How to Install Rotary Vacuum Pump

Reasonable installation of rotary vane vacuum pump can not only ensure the normal operation of the pump, but also prolong the service life of the pump. Then how to install rotary vane vacuum pump correctly? Next, vacuum pump experts will introduce the installation method of rotary vane vacuum pump for you.

First, after opening the box, carefully remove the rotary vane vacuum pump body, spare accessories and instructions and keep them for future reserve. Remove the filler and wipe off the dust and dirt on the surface of the pump. Count the number by packing list.

Secondly, the rotary vane vacuum pump is installed in the room with clean environment, good ventilation and sufficient light to meet the requirements of Article 4. Pumps should be installed in a certain ample site according to the use, so as to facilitate operation and maintenance. See the shape and size of the pump. Rotary vane vacuum pump can be placed on a solid flat ground, without special foundation. If it needs to be fixed, additional screw and foundation can be firmly fixed. See the size of foot screw. If the rotary vane vacuum pump is close to the precision instrument, it should be considered to add shock-proof device.

Connect the vacuum hose or flange to the rotary vane vacuum pump. If the flange is connected, there should be rubber groove on the flange. See figure 50 for the form and size of the flange. The diameter of the pipe connecting the pumped container should not be less than the diameter of the pump intake, the pipe should be short, and the joint should be less. Otherwise, the pumping speed should be affected, and the leakage of the pipe and joint should be small. The gas volume of the pumped container should be in accordance with the pumping speed of the pump. The relationship between the pumping speed of the rotary vane vacuum pump is shown in Fig. 4. It is suggested that a vacuum valve be installed between the pump and the pumped container to control the gas flow. For pumps, it is recommended to install a vent valve (or solenoid valve) to vent the pump when it stops, which can prevent oil return and start easily.

Then, the power supply is connected according to the voltage and wiring mode indicated by the motor sign, and it is suggested that the safety device be used to avoid overload, and the direction of motor rotation should be determined in accordance with the direction of arrow on the pump. Remove the exhaust plug and install the exhaust hood, or remove the sleeve on the exhaust nozzle. The rotary vane vacuum pump needs the cooler to connect to the water source.

Finally, if it is necessary to remove toxic and corrosive ferrous metal gases, gases with chemical changes to vacuum oil, and gases with dust and atmospheric temperature, relevant devices such as neutralization, cooling and filtering should be installed in the intake pipeline to cooperate with the use, otherwise the performance and service life of rotary vane vacuum pump will be affected. When extracting harmful gases to human body, corresponding pipes should be installed to lead the exhausted gases outdoors away from the work area for treatment.

Positive Displacement Blower Repair USA

Positive Displacement blowers use mechanical power to squeeze fluid and thereby increase the pressure. Rotary Vane and Rotary Lobe are the two types of positive displacement blowers, Positive displacement blowers are often driven by direct-coupled electric motors but they can also be driven by gas engines, hydraulic motors, etc in unusual circumstances. Positive displacement blowers are used in pneumatic conveying, for sewage aeration, filter flushing, gas boosting, as well as to move gases of all kinds in the petrochemical industries.

Blowers are specified on the basis of pressure and flow rate. Blowers can be purchased based on the ratio of system inlet pressure and outlet pressure. Some of the important points to be considered while selecting blowers are the structure of blades, the flow capacity, the port design, and more.

Centrifugal blowers resemble centrifugal fans. Multi-stage centrifugal blowers are used to generate greater pressures. In positive displacement industrial blowers, a fixed amount is entrapped and sent forward with greater pressure. They are beneficial to application processes that are prone to clogging.  Industrial blower efficiency is the ratio between the power transferred to the air stream and the power delivered by the motor to the blower. The efficiency of the blower depends upon the type of impeller being used.

Vacuum Pumps are an integral part of industrial manufacturing processes which includes packaging, bottling, drying, degassing, pick and place, to name a few. For smooth and efficient working of any system, pumps are required, and hence it is crucial to understand the features, benefits, and operating principles of vacuum pump technology.

There are two factors that can cause the vacuum pump to inject oil

With the continuous expansion of vacuum technology in various application fields, the demand for direct connected rotary vane pump is increasing. Some foreign vacuum manufacturers have set up professional factories in China because of the large number of pumps, heavy workload of processing and installation, and low quotation. The vacuum pump is a rotary variable volume pump, which can only be used with the previous pump. It has a large pumping speed in a wide pressure range. However, generally speaking, there are two reasons for fuel injection in the exhaust hole of Rongxiang vacuum pump One is that the sealing solvent is too large, and the vacuum pump is too small. The second is the excessive vacuum refueling, which causes the vacuum pump to eject with the exhaust port in the process of operation. Vacuum pump is developing rapidly. Due to the high-speed friction between the vane and the pump body, the oil is easy to be oxidized and decomposed. Especially the diffusion pump often works in high temperature environment, which increases the steam pressure and reduces the vacuum degree in the system. Therefore, the vacuum pump oil is required to have good thermal oxidation stability. Domestic small and medium-sized direct rotary vane pump has passed the technical standard, and the price is far lower than that of foreign pumps, so domestic pumps still have competitive advantages. The key is to deal with the leakage of shaft seal, the function and quality of rotary vane material and vacuum pump oil, ensure the stable and reliable operation of direct connected rotary vane pump under high speed and high temperature, and further improve the water vapor removal ability of domestic direct connected rotary vane pump.

How to choose a manufacturer of vacuum pumps

[guzumachineryusa-blog]

The vacuum pump’s market

The vacuum pump is a large-volume product with a large output and low output value, but it is indeed an essential basic product that directly affects the performance quality of vacuum equipment. Vacuum pumps range from high/ultra-vacuum to coarse/low vacuum, and their products can be roughly divided into 14 categories: High/ultra-vacuum - cryopump, molecular pump, sputter ion pump, titanium sublimation pump, diffusion pump.

6 inch trash pump

Medium vacuum - dry pump, two-stage rotary vane pump, Roots pump, oil booster pump, water vapor jet pump. Coarse/low vacuum - single stage rotary vane pump, slide valve pump, liquid ring pump, reciprocating vacuum pump.

4 inch trash pump

The market for vacuum pumps changes dynamically according to the needs of users. The main drivers of market growth are the rapid development of the semiconductor industry and the growing use of dry pump and molecular pump applications. At present, the global vacuum pump market has annual sales of about 2 billion US dollars, with an annual growth rate of about 7%.

 There are many manufacturers of vacuum pumps in China. The annual sales of all vacuum pumps is about 150 million yuan, which is only equivalent to the annual sales of a vacuum pump from Kinney. Through the analysis of the global vacuum pump market, we can see that the market and application fields of various vacuum pumps are constantly changing and developing. China's vacuum pump manufacturing industry has a long history and solid foundation. Domestic vacuum pumps have been applied and verified in various fields. Some pumps have also been exported to foreign countries and have been recognized by foreign users and received favorable comments. It should be said that China's vacuum pump manufacturing industry is at home and abroad. The market still has huge room for development.Liquid ring pump. Although the liquid ring pump is a rough vacuum pump, it still has a large market in China's petroleum, chemical, electric power, textile, paper, medicine and other fields. In foreign countries, the sales of liquid ring pumps accounted for 14% of the total vacuum pump market, second only to dry pumps, so companies such as Nash, Seimems and Kinney are investing in China or establishing sales networks to expand their market share in China. Since most of the liquid ring pump is casting, the processing requirements are not high, and it is a labor-intensive product. Therefore, the domestic liquid ring pump has a competitive advantage in price. The key is to improve the design, reduce the volume, reduce the weight, improve the efficiency, and reduce the energy. Consumption.

 Slide valve pump

Because the spool valve pump is more durable and reliable, all kinds of vacuum furnaces, coating machines, drying and impregnation equipments at home and abroad use the slide valve pump as the foreline pump, but the sliding valve pump castings are heavy and the processing workload is large, so foreign Each vacuum plant is looking for a partner in China. In order to enable the domestic spool valve to enter the international market, it is necessary to further reduce the vibration and noise of the pump, prevent fuel injection and oil leakage, and improve the reliability of the long-term operation of the spool pump. It’s specially used in self priming trash pump and self priming sewage pump.

 Direct coupling rotary vane pump

With the continuous expansion of vacuum technology in various application fields, the demand for direct-coupled rotary vane pumps is increasing. Due to the large number of such pumps, the processing and assembly work is very large, and the price is very low, so some foreign vacuum manufacturers set up professional factories in China. The domestic small and medium-sized direct-coupled rotary vane pump has been technically passed, and the price is far cheaper than that of the foreign pump. Therefore, the domestic vacuum pump still has a competitive advantage. The key is to solve the shaft seal oil leakage and the performance quality of the rotary vane material and the vacuum pump oil. To ensure the stability and reliable operation of the direct-coupled pump at high speed and high temperature, and to further improve the ability of the domestic direct-coupled rotary vane pump to remove water vapor. It can also fit in 6 inch trash pump.

 Roots pump

From the perspective of the production of Roots pumps abroad, several large foreign companies, such as Leybold, Balzers, Alcatell, Edwards and ULVAC, their sales of Roots pumps accounted for less than 5% of the global sales of Roots pumps. The total of these 5 companies is only 20%. The output of Roots pumps is not large, but the price of foreign Roots pumps is much higher than that of domestic pumps. At present, almost all large and small high-vacuum and medium-vacuum systems at home and abroad are equipped with Roots pumps in order to shorten the pumping time and improve production efficiency. Therefore, the domestic Roots pump must try to enter the international market based on the occupation of the domestic market. Therefore, it is necessary to further reduce the vibration noise of the domestic Roots pump, completely solve the problem of shaft seal oil leakage, improve the appearance quality of the pump, and improve the smoothness and cleanliness of the pump. In addition, it is necessary to consider that the power frequency of some countries and regions is 60Hz, and it is necessary to ensure the reliability of the long-term operation of the Roots pump under the condition of increasing the speed. The self priming pump have roots pump also.

 At present, domestic air-cooled direct-flow atmospheric Roots pumps are progressing rapidly and are technically mature. Since the pump is equipped with a gas cooler below the exhaust port, and a part of the cooled gas is returned to the pump chamber through the pipe to cool the rotor, so that the heat of compression is balanced, the pump can be directly exhausted to the atmosphere. In order to meet the requirements of different ultimate vacuum, the pumps can be used in series. Generally, an air-cooled straight-flow atmospheric Roots pump is added in front, and the ultimate vacuum achieved is one order of magnitude higher than that of the foreline pump. This type of pump is actually a dry pump because there is no working medium in the pump chamber. At present, this air-cooled direct-flow atmospheric Roots pump and unit has been tested in the long-term operation of petroleum, chemical, plastics, pesticides, turbine rotor dynamic balance, aerospace space simulation and other devices, so it should be promoted in China. And application. 4inch trash pump also have this.

 5. Molecular pump

Molecular pumps are used in many foreign semiconductor fields to replace cryopumps, especially sputtering, etching and LCVD. The composite molecular pump and traction pump are used as the main pump.

Since the pumping speed of the molecular pump to water vapor is only one quarter of the pumping speed of the same-diameter cryopump, the molecular pump has a longer exhaust time than the cryopump. In order to increase the pumping speed, a low-temperature cold plate of -130 ° C ~ -150 ° C is installed on the inlet side of the molecular pump, which is called a low temperature molecular pump. The water vapor is captured by the cryogenic plate, and other gases are pumped away by the molecular pump. This low-temperature molecular pump is applied to a vacuum coating device, which not only improves production efficiency but also improves film quality. With the rapid development of China's semiconductor industry, film industry and scientific research, molecular pumps should be the focus of the development of China's vacuum pump manufacturing industry. First of all, the molecular pump should establish a complete series from small to large, and research and development of various composite molecular pumps, traction pumps and low temperature molecular pumps to meet the needs of different occasions.

6. Dry pump

The dry pump market in foreign countries continues to grow, and its main drivers are the rapid development of the semiconductor industry, chemical industry and film industry. In Japan, the semiconductor industry has replaced dry-type vacuum pumps with oil-sealed mechanical pumps. More than 45% of the European and American semiconductor industries have replaced the oil-sealed mechanical pumps with dry vacuum pumps, which greatly improved the performance and quality of the products. In order to meet the requirements of different application fields and different working conditions, there are multi-stage Roots vacuum pumps, multi-stage claw vacuum pumps, screw vacuum pumps, scroll vacuum pumps, reciprocating piston vacuum pumps and turbine oil-free vacuum pumps. The ultimate pressure is from 10Pa to 10-2Pa, and the pumping speed is from 20m3/h to 500m3/h. According to statistics, the current domestic dry pump application is less than 1%. The domestic dry pumps for the semiconductor industry are all imported from abroad, and the price is very expensive. Therefore, China should vigorously research and develop dry pumps, making dry pumps a new economic growth point for China's vacuum industry.

Several Vacuum Pumps in Chemical Industry

1. Several kinds of vacuum pumps commonly used in chemical industry-the common vacuum pumps in chemical industry can be simply divided into variable-volume vacuum pumps and jet vacuum pumps. Variable-volume vacuum pumps are devices that use the periodic change of pump chamber volume to complete suction and exhaust. Reciprocating vacuum pumps, rotary vane vacuum pumps, slide valve vacuum pumps, water ring vacuum pumps and Roots vacuum pumps belong to variable-volume vacuum pumps. Type vacuum pump. Jet vacuum pump is a momentum transfer pump that uses the high-speed jet generated by the pressure drop of Venturi effect to transport gas to the outlet. Water jet vacuum pump, steam jet vacuum pump, steam-water series jet vacuum pump and steam-water combined jet vacuum pump belong to the same kind of jet vacuum pump. 2. Working Principle and Advantages and Disadvantages of Variable Volume Vacuum Pump

(1) Reciprocating vacuum pump, rotary vane vacuum pump, slide valve vacuum pump and Roots vacuum pump inhale, compress and discharge gas by reciprocating motion or rotation of piston. Their advantage is that the vacuum degree of the new pump is relatively high, but the piston is a running part, so the wear of the piston is inevitable. With the increase of maintenance times, the working vacuum degree will continue to decline until it can not meet the production requirements. This kind of pump has the disadvantage of high working noise, high fuel consumption and high failure rate. Generally, it needs to open a spare one, which invisibly increases the cost of equipment investment and operation. In addition, if this kind of pump is used to pump condensable gases such as suction steam, lubricating oil will be emulsified, so it can only be used to suck non-condensable (air) gases, nor can it suck medium with granular shape, which limits its scope of application.

(2) Water ring vacuum pump rotates by an eccentric rotor with multi-blades installed in the pump shell, throwing water into the pump shell to form a water ring concentric with the pump shell, and the water ring and the rotor blades form a volume periodic change, thus inhaling, compressing and discharging gas. It has the advantages of large suction capacity at low vacuum and direct suction of condensable gases such as water vapor. Its shortcomings are low vacuum, inability to suck granular media, high-speed rotation of the rotor is not easy to do anti-corrosion treatment, so it can not suck corrosive media. 3. Working Principle and Advantages and Disadvantages of Jet Vacuum Pump

Jet vacuum pump is a momentum transfer pump that uses the high-speed jet generated by the pressure drop of Venturi effect to transport gas to the outlet. It is divided into water jet vacuum pump, steam jet vacuum pump, steam-water series jet vacuum pump, steam-water combination jet vacuum pump. Jet vacuum pump is widely used in chemical operation because of its wide vacuum range, direct suction of condensable gases such as water vapor and granular media, simple structure, easy operation, small maintenance of non-operating components, energy saving and consumption reduction.

Under what conditions should vacuum pump be used best?

Many users don't understand the use conditions of vacuum pump, which often causes the damage of vacuum pump, so under what conditions is the best use of vacuum pump? According to the basic needs of users and their own experience, the technicians of vacuum pump factory summarized the following points, hoping to help you. (1) The selection of vacuum pump should be based on the user's specific process, such as the vacuum degree, the pumping rate, the selection of power supply voltage, etc. (2) The vacuum pump should be cleaned and changed regularly. Especially for the rotary vane vacuum pump, kerosene or straight run gasoline shall be used for cleaning. After cleaning, all parts shall be dried, air dried or blown with a blower. When changing oil, 100 × or 1 × clean vacuum pump oil shall be selected. If other oil is used instead, the vacuum degree will be seriously affected, the vacuum pump shall be placed in a clean and dry place. (3) The connection pipeline between vacuum pump and user system shall be mainly short and thick, and elbows shall be minimized. If there are elbows, all joints shall be strictly sealed to ensure no air leakage. (4) The temperature of the gas pumped by the vacuum pump is also limited. If the temperature of the gas pumped by the water ring vacuum pump is higher than 40 ℃, a gas cooling device shall be added. If there is liquid drop, condensation dehumidification device shall be added. If the pumped gas has corrosiveness or chemical reaction with oil, the material of vacuum pump shall be selected. (5) Before starting the pump, check whether the rotation direction of the motor is correct (when checking the direction, take off the drive belt first to avoid oil gushing out when the motor reverses). The inspection methods of the rotary vane vacuum pump and the water ring vacuum pump are different, and check whether the lubrication system is reliable and the oil quantity is appropriate. （6） The oil temperature of vacuum pump in operation shall not exceed 75 ℃, and there shall not be too much noise and vibration, otherwise it shall be shut down for maintenance. (7) When stopping the pump, the valve connecting the vacuum system shall be closed first, and the vent valve shall be opened to prevent the pump oil from being sucked back into the vacuum system, and then the power supply of the motor shall be cut off. To sum up, the service life of the vacuum pump is not only related to the quality of the vacuum pump itself, but also requires the user to use it in strict accordance with the requirements of our factory. It is not allowed to dismantle or operate the pump without permission under unclear conditions.

Useful of vacuum pump

The vacuum pump is a large-volume product. The output is large. The output value is not high. But it is indeed an essential basic product that directly affects the performance quality of vacuum equipment. Vacuum pumps range from high/ultra vacuum to coarse/low vacuum. Its products can be roughly divided into 14 categories: High / ultra vacuum - . Cryopump molecular pump sputtering ion pump titanium sublimation pump diffusion pump. Medium vacuum - dry pump two-stage rotary vane pump Roots pump oil booster pump steam jet pump. Thick/low vacuum - . Single-stage rotary vane pump slide valve pump liquid ring pump reciprocating vacuum pump.

  The market for self priming trash pump changes dynamically according to the needs of users. The main drivers of market growth are the rapid development of the semiconductor industry and the growing use of dry pump and molecular pump applications. Currently. The global vacuum pump market has annual sales of approximately $2 billion. The annual growth rate is around 7%.

  self priming pump

  There are many manufacturers of vacuum pumps in China. The annual sales of all self priming trash pump are about 150 million yuan. It is only equivalent to the annual sales of a vacuum pump from a company in Kinney, USA. We can see from the analysis of the global vacuum pump market. The market and application fields of various types of vacuum pumps are constantly changing and developing. China's vacuum pump manufacturing industry has a long history and a solid foundation. Domestically produced pumps have been applied and proven in various fields. Some pumps are also exported abroad. It has been recognized by foreign users and has been well received. It should be said that China's vacuum pump manufacturing industry still has huge room for development in the domestic and foreign markets.

  Liquid ring pump

  Although the self priming sewage pump is a rough vacuum pump. But in our country's oil. Chemical industry. electric power. Light textile. papermaking. There is still a large market in the fields of medicine and so on. In foreign countries. Sales of liquid ring pumps accounted for 14% of the total vacuum pump market. Second only to dry pumps. Therefore, companies such as Nash.Seimems and Kinney are investing in factories or establishing sales networks in China. Continue to expand market share in China. Since the liquid ring pump is mostly cast. Processing requirements are not high. It is a labor-intensive product. Therefore, the domestic self priming sewage pump has a competitive advantage in price. The key is to improve the design. Reduce the size. reduce weight. Improve efficiency. Reduce energy consumption.

  2. Slide valve pump

  Because the 6 inch trash pump is more durable. reliable. Various vacuum furnaces at home and abroad. Coating machine and drying. Equipment such as impregnation uses a spool valve as a foreline pump. However, the spool valve castings are heavy. The processing workload is large. Therefore, foreign vacuum plants are looking for partners in China. In order to enable domestic spool valve pumps to enter the international market. The vibration and noise of the 6 inch trash pump must be further reduced. Eliminate fuel injection and oil leakage. Improve the reliability of the long-term operation of the spool pump.

  3. Direct coupling wet prime pump

  With the continuous expansion of vacuum technology in various application fields. The demand for direct-coupled rotary vane pumps is growing. Because of the large number of such pumps. Processing and assembly work is very large. The price is very low. Therefore, some foreign vacuum manufacturers have established professional factories in China. Domestic small and medium-sized direct-coupled rotary vane pumps have been technically passed. The price is far cheaper than the foreign pump. Therefore, domestic pumps still have a competitive advantage. The key is to solve the problem of shaft seal oil leakage and the performance quality of the rotary vane material and wet prime pump oil. Make sure the direct pump is at high speed. Stable performance and reliable operation at high temperatures. At the same time, it is necessary to further improve the ability of the domestic direct-spinning rotary vane pump to remove water vapor.

  4. Roots pump

  From the perspective of the production of Roots pumps abroad. Several large foreign companies. Such as Leybold.Balzers.Alcatell.Edwards and ULVAC. The sales of their Roots pumps accounted for less than 5% of the global sales of Roots pumps. These 5 totals are only 20%. Roots pump production is not large. But the price of foreign Roots pumps is much higher than domestic pumps. Currently. Almost all large and small high vacuum and medium vacuum systems at home and abroad. In order to shorten the pumping time. The productivity is enhanced with a Roots pump. Therefore, the domestic Roots pump must try to enter the international market on the basis of occupying the domestic market. Therefore, it is necessary to further reduce the vibration noise of the domestic Roots pump. Thoroughly solve the problem of shaft seal oil leakage. Improve the appearance quality of the pump. Improve the smoothness and cleanliness of the pump. In addition, it is also necessary to consider that some countries and regions have a power frequency of 60 Hz. It is also necessary to ensure the reliability of the Roots pump for long-term operation with increased speed.

  4 inch trash pump

  Currently. Domestic air-cooled direct-flow atmospheric Roots pumps are progressing rapidly. Technically mature. Since this pump is equipped with a gas cooler below the exhaust port. A portion of the cooled gas is returned to the pump chamber through a conduit to cool the rotor. Thereby the compression heat is balanced. So this pump can go straight to the atmosphere. In order to meet the requirements of different ultimate vacuum. This type of pump can be used in series. Generally, an air-cooled straight exhaust atmospheric Roots pump is added in front. The ultimate vacuum achieved is an order of magnitude higher than that of the foreline pump. This type of pump has no working medium in the pump chamber. It is actually a dry pump. Currently. This air-cooled straight-line atmospheric Roots pump and unit is already in oil. Chemical industry. plastic. The dynamic balance of the pesticide turbine rotor.

  5. Molecular pump

  Molecular pumps are used in many process areas in foreign semiconductors to replace cryogenic pumps. Especially sputtering. Etching and LCVD devices are used as the main pump for the color composite molecular pump and the traction pump.

  Since the pumping speed of the molecular pump to water vapor is only one quarter of the pumping speed of the same-diameter cryopump, the molecular pump has a longer exhaust time than the cryopump. In order to increase the pumping speed, one of the inlets of the molecular pump is installed abroad. - 130 ° C - 150 ° C low temperature cold plate, called low temperature molecular pump, water vapor is captured by the cryogenic plate, other gases are pumped away by the molecular pump. This low temperature molecular pump is applied to a vacuum coating device. It not only improves production efficiency but also improves film quality. With China's semiconductor industry. The film industry and scientific research are developing rapidly. Molecular pump should be the focus of the development of China's vacuum pump manufacturing industry. First, the molecular pump should build a complete series from small to large. And research and development of various composite molecular pumps, traction pumps and low temperature molecular pumps to meet the needs of different occasions.

  6. Dry pump

  The engine driven trash pump market in foreign countries continues to grow. Its main driver comes from the semiconductor industry. chemical industry. The rapid development of the film industry. In Japan. The semiconductor industry has replaced dry-type vacuum pumps with oil-filled mechanical pumps. More than 45% of the semiconductor industry in Europe and America replaced the oil-sealed mechanical pump with a dry vacuum pump. Greatly improve the performance and quality of the product. In order to meet the requirements of different application areas and different working conditions. There are multi-level Roots vacuum pumps in foreign countries. Multi-stage claw engine driven trash pump. Screw vacuum pump. Scroll vacuum pump. Reciprocating piston vacuum pump and turbo oil-free vacuum pump. The ultimate pressure is from 10 Pa to 10 2 Pa. The pumping speed is from 20 cubic meters / H - 500 cubic meters / hour. According to the statistics. At present, the domestic dry pump application is less than 1% domestic. Dry pumps for the semiconductor industry are all imported from abroad. Its price is very expensive. Therefore, China should vigorously research and develop dry pumps. Make dry pumps a new economic growth point for China's vacuum industry.
