Roots rotary vane vacuum unit is a low and high vacuum obtaining equipment with roots vacuum pump as the main pumping pump and single-stage or double-stage rotary vane pump as the front stage pump. The whole unit is arranged on a frame, equipped with pipeline, valve and electrical operation control box, and also equipped with cooling water pipe system. The unit is compact in structure and convenient in use, with high vacuum degree, low noise and sustainable work.
The ratio of the nominal pumping speed of each pump of roots rotary vane vacuum unit is generally between 41 and 101. In order to prevent the front rotary vane vacuum pump from shutting down and returning oil, an electromagnetic vent valve is installed on the front pipeline, whose action is linked with the motor of the front rotary vane vacuum pump, so as to ensure the normal and efficient operation of the pump.
In order to improve the pumping performance of the vacuum unit, reach a higher limit vacuum, improve the pumping speed characteristics at low inlet pressure and use a smaller specification of the front pole pump for large vacuum units, roots vane vacuum units can also be used in series with two-stage roots vacuum pump to form a three-stage unit according to customer requirements.
