2、spensable based products. The vacuum pump market inaccordanee with the needs of users and happen dynamics. Market growth from the main driv ing force of the rapid developme nt of the semic on ductor in dustry and dry pump and molecular pump applicati on field of wide ning.Keywords: vacuum pump; mark

3、et development; expandIntroduction: At present, the vacuum pump market sales of about $20 billionin annualrate around 7%. Our producti on of vacuum pump manu facturer of vacuum pump, all in many sales are about 1.5 billionyuan, is only American KINNEYcompany annual sales1 2of vacuum pump . Based on

4、the an alysis of global vacuum pump market we can seethat all types of vacuum pump market and application fields are constantly changing and developing.Our country vacuum pump manufacturing has a long history and strongfoun dati on, homebred vacuum pump has bee n applied in many differe nt fields an

5、d validated, some pumps also exported abroad, get foreign customers approval and good reputation,it should be said that China vacuum pump manufacturing in domestic andintern ati onal market still has the huge developme nt space.1. Water-ring vacuum pumpAlthough water-ri ng vacuum pump bel ongs to ro

6、ugh vacuum pumps, but in our country of petroleum, chemical in dustry, electric power, textile, paper, pharmaceutical products still has a large market. In a foreig n coun try, water ring vacuum pumps sales3total market of 14% , after dry pump, so SEIMEMS and NASH, such compa nies inChi na KINNEYinv

7、 estme nt and con struct ion or establish sales n etwork, and3constantly expand in our market share . Because water ring pumps are mostly casting, processing requirements are not high, of labor-intensive products, so the domestic water ring pump on price competitive advantage, the key is to design i

At prese nt, this kind of air type in-li ne atmospheric ROM Bates pump and crew have in petroleum, chemical, plastic, pesticide, turb ine

20、rotor dyn amic bala nee, aerospace space simulation device got Iong-term operation of the test, so it should be popularized and applied in China5.5. Molecular pumpMolecular pump in the field of many foreig n semic on ductor process occasi on is used instead of cryogenic pumps, especially sputtering,

21、 etching and LCVD devices are adopted complex molecular pump and tractio n pump as the main pump.Because of molecular pump to water vapor is only the pumping speed with diameter cryoge nic pumps pump ing speed in the quarter, so molecular pump exhaust time tha n cryoge nic pumps long. In order to im

In Japa n, semic on ductor in dustry is full already use dry vacuum pump oil seal type JiXieBe ng, euramerica n in stead of semic on ductor in d

26、ustry more tha n 45% replaced with dry vacuum pump oil seal type JiXieBeng, greatly improving the product performa nee and quality .In order to meet differe nt applicati ons and requireme nts of different working conditions, abroad have multistage ROM Bates vacuum pump, multi-stage claw type vacuum

27、pump, screw vacuum pump and the vacuum pump, reciprocati ng type vortex pist on vacuum pump and turb ine oil free pump etc. Extreme pressure from 10PA 10-2PA, pumping speed from 20M3 / H 500M3 / H. Accord ing to statistics, at prese nt domestic dry pump applicatio n is in sufficie nt still 1%7, dome

28、stic semic on ductor in dustry with dry pump all imported from abroad, its price is very expensive. Therefore, our country should vigorously research and developme nt dry pump, and let the dry vacuum pump become Chin a's in dustrial new econo mic growth point.7、Vacuum pump tech no logy progress

29、trendTech no logy is the impulsi on of the dema nd of the market. Because the vacuum tech no logy, expa nsion and the rapid growth of high-tech, the domestic market to the vacuum pump tech no logy level put forward higher request. The vacuum pump product ion en terprises must through tech ni cal inn

41、he expansion of the land. At present domestic built semic on ductor in tegrated circuit producti on line, almost all of the dry vacuum pump (including other vacuum equipment) are all imported mainly from Britain, Japa n, Germa ny, America, etc. Domestic product ion of dry vacuum pump from en teri ng

42、 the field was very difficult, making the dry vacuum pump this future vacuum pro-duct ion equipme nt lead ing products in our country through a very difficult situati on. The cause of this situati on was the main cause of dry vacuum pump in our startti ng eve ning, just a start n amely facing abroad

44、vided up the domestic market, and establish feet, domestic producti on because of the dry vacuum pump has lost market incentive, did not have the developme nt power, progress is slow. In dustry experts agree that the dry vacuum pump is vacuum pro-duct ion equipme nt the directi on of developme nt, b

45、ut also vacuum pro-ducti on means "cutt in g-edge tech no logy", our coun try's vacuum pump industry must make a differenee in this field, the first in food, chemical, pharmaceutical, etc. After these markets to cultivate and exercise, and the n in to the semic on ductor in dustry. To

46、make the in dustry of keep ing pace with times.At prese nt domestic molecular pump shall improve its series and develop many varieties, such as low molecular pump, complex molecules pump etc, gradually expa nd the market.7.4、To in troduce adva need foreig n tech no logy, make domestic in depe ndent

47、bran ds.In troduce the foreig n adva need tech no logy, improve our scie ntific and tech no logical content of products in other in dustries have successful experie nee. In the developme nt of vacuum pro-duct ion equipme nt in the high-e nd product in troducti on of foreig n tech no logy, and good d

48、igesti on absorpti on, will cha nge our country product otaku pin lia ng speed low-skilled, quality and tech no logy level cannot meet the dema nd of market of the status quo. But we the in troduct ion of foreig n tech no logy, should pay special atte nti on to two poin ts: one is the emphasis on di

49、gest absorb, and based on this, cultivate enterprise of independent intellectual property rights and innovation ability. 2 it is not repeat import blindly, aiming at the intern ati onal on con temporary latest tech no logy, avoid in troduc ing gen erati on, backward gen erati on. The in troducti on

50、of foreig n tech no logy is not an end, but a means, through in troduc ing tech no logy ultimately make domestic in depe ndent brand!7.5、Grasp product structure adjustment to develop to meet market dema nd of the products.The traditi onal vacuum equipme nt we produce decades in the n ati on wide for

51、m became the stability of the product distribution pattern. But with the high speed developme nt of economy, the in formati on tech no logy, aerospace, nano scie nee and other high-tech bow I guide of today's scie nee and tech no logy developme nt trend. And these high-tech vacuum pro-duct ion e

52、quipme nt's developme nt is in separable from the basic equipme nt. At prese nt domestic situati on is still in product ion vacuum pump producti on en terprise traditi onal product mainly in the traditi onal applicati on field occupied more tha n 90% of the market share .In the high-tech fields,

53、 domestic products in the tech ni cal level and quality will fail to meet dema nd, more tha n 90 perce nt market share by foreig n product occupati on. Domestic vacuum pro-duct ion products and the developme nt of new high tech no logy, product structure apart seriously in compatible. Most en terprises only expect to exist ing old products, and con sta ntly in creased product ion and in creased profits, this possibility in curre nt competitive market will be more and more small. In today's domestic and foreign market patter n in front, as soon as possible adjustme nt of product struc
