| TV towers, vacuum pump is a product, | | | | vane pump demand is growing. Because of this |
| production lot, the output value is not high, but it | | | | high number of pumps, processing and assembly |
| is indeed a direct impact on the quality of the | | | | of the heavy workload, the price also very low, |
| vacuum properties of complete sets of | | | | so some foreign manufacturers in China, a |
| equipment essential for basic products. Vacuum | | | | professional vacuum plant. Domestic small and |
| pump from the high / ultra-vacuum to a thick / | | | | medium sized Direct rotary vane pump is |
| low vacuum, and its products broadly classified | | | | technically had passed, prices will be cheaper than |
| into 14 broad categories: | | | | the pump outside, it still has competitive |
| High / Ultra Vacuum - cryogenic pumps, molecular | | | | advantages of domestic pump, the key is to |
| pumps, sputter ion pumps, titanium sublimation | | | | address the seal oil spills, as well as rotary vane |
| pumps, diffusion pumps. | | | | vacuum pump oil performance materials and |
| Vacuum - Dry pumps, dual-stage rotary vane | | | | quality issues to ensure that direct-pump in |
| pumps, Roots pumps, oil booster pumps, water | | | | high-speed, high temperature stable performance |
| vapor jet pump. | | | | and reliable operation, while also further enhance |
| Coarse / low vacuum - single-stage rotary vane | | | | the domestic Direct rotary vane pump water |
| pumps, rotary piston pump, liquid ring pumps, | | | | vapor extraction capabilities. |
| reciprocating vacuum pump. | | | | 4. Roots pumps |
| Vacuum pump market place according to the | | | | Roots pumps from abroad, the production point |
| needs of the user dynamics. The main driver of | | | | of view, several large foreign companies, such as |
| market growth from the rapid development of | | | | Leybold, Balzers, Alcatell, Edwards, and ULVAC, |
| the semiconductor industry, as well as molecular | | | | they Gejia Roots pump sales accounted for the |
| pump dry pumps and application fields are | | | | proportion of the global sales of Roots pump no |
| expanding. | | | | more than 5% This 5 total only 20%, Roots |
| At present, the global market, with annual sales of | | | | pump output is not, but abroad, Roots pump |
| vacuum pumps about 20 billion U.S. dollars, annual | | | | prices much higher than domestic pump. At |
| growth rate of about 7%. | | | | present, almost all domestic and foreign large or |
| Vacuum pump manufacturers in China produce a | | | | small, high-vacuum and the vacuum system, in |
| lot, all vacuum annual sales of about 1.5 billion | | | | order to shorten the extraction time, improve |
| yuan, only the equivalent of the United States | | | | production efficiency are equipped with Roots |
| with annual sales of Kinney's a vacuum pump. | | | | pumps, Roots pumps must be made so the |
| Through the analysis of the global pump market, | | | | occupation of the domestic market to enter the |
| we can see, all kinds of vacuum pumps on the | | | | international market on the basis of , so that |
| market and applications are constantly changing | | | | must be made to further reduce vibration noise |
| and development. Vacuum pump manufacturers in | | | | Roots pump, seal leakage solve problems, |
| China has a long history and strong foundation, | | | | improve the appearance quality of the pump to |
| made really pumps have been applied in various | | | | improve pump the finish and cleanliness. Also, |
| fields and have been verified, and some pumps | | | | some countries and regions, taking into account |
| are exported abroad, recognized by foreign | | | | the power supply frequency of 60Hz, even more |
| customers and well received, we should say that | | | | to ensure that the Roots pump in improving the |
| my vacuum pump manufacturers in the domestic | | | | speed of the case of long-running reliability. |
| outside the market is still enormous room for | | | | 5. Molecular Pump |
| development. | | | | Molecular pump outside the semiconductor field is |
| 1. Liquid-Ring Pump | | | | used to replace a number of occasions, cryogenic |
| Although the liquid ring vacuum pumps are rough, | | | | process pump, in particular, sputtering, etching, |
| but in China's petroleum, chemical, electric power, | | | | and LCVD color devices are complex molecules |
| textile, papermaking, medicine and other areas | | | | such as pumps and traction pump as the main |
| there is still a huge market. In other countries, | | | | pump. |
| liquid ring vacuum pump sales accounted for 14% | | | | 6. Dry pumps |
| of the market, second only to dry pumps, so | | | | Overseas markets dry pumps is growing, the |
| Nash, Seimems, and Kinney and other companies | | | | main driver from the semiconductor industry, |
| are investing in building factories in China or the | | | | chemical industry, film industry developed rapidly. |
| establishment of sales network, and continuously | | | | In Japan, the semiconductor industry have all been |
| expand our market share. As the liquid ring pumps | | | | replaced with a dry-type vacuum pump oil seal |
| are mostly casting, processing requirements are | | | | mechanical pump, Europe and the United States |
| not high, is a labor-intensive products, they are in | | | | semiconductor industry for more than 45% of |
| the price of domestic liquid ring pumps have a | | | | the dry-type vacuum pumps instead of oil seal |
| competitive advantage, the key is to improve the | | | | mechanical pump, greatly improved product |
| design, reduce volume, reduce weight, improve | | | | performance and quality. In order to meet |
| efficiency, reduce to consumption. | | | | different applications and different operating |
| 2. Rotary piston pump | | | | conditions of the request, a number of levels of |
| As the slide-valve pump is more durable, reliable, | | | | foreign Roots vacuum pumps, multi-claw-type |
| domestic and international variety of vacuum | | | | vacuum pumps, screw-type vacuum pumps, scroll |
| furnaces, coating machines and drying, dipping and | | | | vacuum pumps, reciprocating vacuum pumps, and |
| other equipment are used as a pre-slide-valve | | | | turbo oil-free vacuum pump and so on. Extreme |
| pump pump, but the slide-valve pump re-casting, | | | | pressure from 10Pa ~ 10-2Pa, pumping speed |
| processing a larger workload, so The vacuum of | | | | from 20m3 / h ~ 500m3 / h. According to |
| foreign factories in China looking for partners. In | | | | statistics, the application of domestic dry pumps |
| order to make homemade rotary piston pump | | | | less than 1% of the domestic semiconductor |
| can enter the international market, we must | | | | industry to use all of the dry pumps imported |
| further reduce the vibration of the pump noise, to | | | | from abroad, its price is very expensive. |
| eliminate fuel injection and oil spills, improve the | | | | Therefore, China should vigorously research and |
| rotary piston pump long-running reliability. | | | | development of dry pumps, so that dry industrial |
| 3. Direct Rotary Vane Pumps | | | | vacuum pumps become China's new economic |
| With the vacuum technology in various areas of | | | | growth point. |
| applications continues to expand, Direct rotary | | | | |
