长期以来,我国发展双级滑阀真空泵遇到不少困难和挑战,标准制定后相隔二十多年才有生产2H-150等产品。实际上由于大抽速的双级滑阀真空泵设计制造会遇到动平衡、控制双级供油、降低噪声等一系列的问题,所以其设计制造给厂方带来很大麻烦。但是大抽速双级滑阀真空泵在使用上有很广泛的应用前景,本文介绍大抽速双级滑阀真空泵开拓发展的必要性和介绍研制成功的2H-150滑阀真空泵设计特点,并提出发展更大抽速的双级滑阀真空泵的必要性。
For a long time, the development of China's double-stage slide valve vacuum pump encountered many difficulties and challenges, standard development after more than 20 years after the production of 2H-150 and other products. In fact, the design and manufacture of double-stage slide valve vacuum pump with large pumping speed will encounter a series of problems such as dynamic balance, two-stage oil supply control, noise reduction and so on. However, there is a wide range of applications of the large pumping speed double-stage spool vacuum pump. This paper introduces the necessity of developing the large pumping speed double-stage spool vacuum pump and introduces the design features of the developed 2H-150 sliding valve vacuum pump. Necessity of developing double-stage slide valve vacuum pump with bigger pumping speed.
