China's Huge Market Space Vacuum Pump Manufacturing Industry

  TV towers, vacuum pump is a product, production lot, the output value is not high, but it is indeed a direct impact on the quality of the vacuum properties of complete sets of equipment essential for basic products. Vacuum pump from the high / ultra-vacuum to a thick / low vacuum, and its products broadly classified into 14 broad categories:

High / Ultra Vacuum - cryogenic pumps, molecular pumps, sputter ion pumps, titanium sublimation pumps, diffusion pumps.

Vacuum - Dry pumps, dual-stage rotary vane pumps, Roots pumps, oil booster pumps, water vapor jet pump.

Coarse / low vacuum - single-stage rotary vane pumps, rotary piston pump, liquid ring pumps, reciprocating vacuum pump.

Vacuum pump market place according to the needs of the user dynamics. The main driver of market growth from the rapid development of the semiconductor industry, as well as molecular pump dry pumps and application fields are expanding.

At present, the global market, with annual sales of vacuum pumps about 20 billion U.S. dollars, annual growth rate of about 7%.

Vacuum pump manufacturers in China produce a lot, all vacuum annual sales of about 1.5 billion yuan, only the equivalent of the United States with annual sales of Kinney's a vacuum pump. Through the analysis of the global pump market, we can see, all kinds of vacuum pumps on the market and applications are constantly changing and development. Vacuum pump manufacturers in China has a long history and strong foundation, made really pumps have been applied in various fields and have been verified, and some pumps are exported abroad, recognized by foreign customers and well received, we should say that my vacuum pump manufacturers in the domestic outside the market is still enormous room for development.

  1. Liquid-Ring Pump

Although the liquid ring vacuum pumps are rough, but in China's petroleum, chemical, electric power, textile, papermaking, medicine and other areas there is still a huge market. In other countries, liquid ring vacuum pump sales accounted for 14% of the market, second only to dry pumps, so Nash, Seimems, and Kinney and other companies are investing in building factories in China or the establishment of sales network, and continuously expand our market share. As the liquid ring pumps are mostly casting, processing requirements are not high, is a labor-intensive products, they are in the price of domestic liquid ring pumps have a competitive advantage, the key is to improve the design, reduce volume, reduce weight, improve efficiency, reduce to consumption.
2. Rotary piston pump

As the slide-valve pump is more durable, reliable, domestic and international variety of vacuum furnaces, coating machines and drying, dipping and other equipment are used as a pre-slide-valve pump pump, but the slide-valve pump re-casting, processing a larger workload, so The vacuum of foreign factories in China looking for partners. In order to make homemade rotary piston pump can enter the international market, we must further reduce the vibration of the pump noise, to eliminate fuel injection and oil spills, improve the rotary piston pump long-running reliability.

3. Direct Rotary Vane Pumps

With the vacuum technology in various areas of applications continues to expand, Direct rotary vane pump demand is growing. Because of this high number of pumps, processing and assembly of the heavy workload, the price also very low, so some foreign manufacturers in China, a professional vacuum plant. Domestic small and medium sized Direct rotary vane pump is technically had passed, prices will be cheaper than the pump outside, it still has competitive advantages of domestic pump, the key is to address the seal oil spills, as well as rotary vane vacuum pump oil performance materials and quality issues to ensure that direct-pump in high-speed, high temperature stable performance and reliable operation, while also further enhance the domestic Direct rotary vane pump water vapor extraction capabilities.

4. Roots pumps

Roots pumps from abroad, the production point of view, several large foreign companies, such as Leybold, Balzers, Alcatell, Edwards, and ULVAC, they Gejia Roots pump sales accounted for the proportion of the global sales of Roots pump no more than 5% This 5 total only 20%, Roots pump output is not, but abroad, Roots pump prices much higher than domestic pump. At present, almost all domestic and foreign large or small, high-vacuum and the vacuum system, in order to shorten the extraction time, improve production efficiency are equipped with Roots pumps, Roots pumps must be made so the occupation of the domestic market to enter the international market on the basis of , so that must be made to further reduce vibration noise Roots pump, seal leakage solve problems, improve the appearance quality of the pump to improve pump the finish and cleanliness. Also, some countries and regions, taking into account the power supply frequency of 60Hz, even more to ensure that the Roots pump in improving the speed of the case of long-running reliability.

  5. Molecular Pump

Molecular pump outside the semiconductor field is used to replace a number of occasions, cryogenic process pump, in particular, sputtering, etching, and LCVD color devices are complex molecules such as pumps and traction pump as the main pump.

  6. Dry pumps

Overseas markets dry pumps is growing, the main driver from the semiconductor industry, chemical industry, film industry developed rapidly. In Japan, the semiconductor industry have all been replaced with a dry-type vacuum pump oil seal mechanical pump, Europe and the United States semiconductor industry for more than 45% of the dry-type vacuum pumps instead of oil seal mechanical pump, greatly improved product performance and quality. In order to meet different applications and different operating conditions of the request, a number of levels of foreign Roots vacuum pumps, multi-claw-type vacuum pumps, screw-type vacuum pumps, scroll vacuum pumps, reciprocating vacuum pumps, and turbo oil-free vacuum pump and so on. Extreme pressure from 10Pa ~ 10-2Pa, pumping speed from 20m3 / h ~ 500m3 / h. According to statistics, the application of domestic dry pumps less than 1% of the domestic semiconductor industry to use all of the dry pumps imported from abroad, its price is very expensive. Therefore, China should vigorously research and development of dry pumps, so that dry industrial vacuum pumps become China's new economic growth point.
