Roots vacuum pump unit will be widely used

With the continuous development of economy, roots vacuum pump unit also develops very fast, and because of its rapid development, vacuum pump factory thinks roots vacuum pump unit should be widely promoted and applied in China. Today, let's learn about the development of Roots vacuum pump unit.

1、 At present, almost all large or 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 the production efficiency. Therefore, the domestic roots vacuum pump must try to enter the international market on the basis of occupying the domestic market. In this way, we must further reduce the vibration and noise of the roots pump, thoroughly solve the problem of shaft seal oil leakage, and improve the pump The appearance quality of the pump can improve the smoothness and cleanliness of the pump;

2、 The sales of Roots vacuum pump units account for no more than 5% of the global sales volume of Roots pumps. The total sales volume of these five pumps is only 20%. The output of Roots pumps is not large, but the price of overseas Roots pumps (roots vacuum pump units) is much higher than that of domestic pumps;

3、 In order to meet the requirements of different limit vacuum degree, this kind of pump can be used in series. Generally, an air-cooled Roots pump is added in front of Roots vacuum pump unit, and the ultimate vacuum is one order of magnitude higher than that of the previous stage pump. Because there is no working medium in the pump cavity, this kind of pump is also a dry pump. At present, this kind of air-cooled direct exhaust air roots pump and its unit have been tested in petroleum, chemical, plastic, pesticide, steam turbine rotor dynamic balance, aerospace space simulation and other devices for a long time. Therefore, roots vacuum pump unit should be vigorously promoted and applied in China.
