1、This equipment is a multi unit vacuum system equipment developed by our company, which provides vacuum pumping function for the operation of the immersion machine in the on-site workshop. It can freely set the operating parameters of the vacuum range to achieve the best state of vacuum system operation and on-site matching, meeting the workshop's use of vacuum;
2、The equipment adopts PLC control, with stable and reliable performance, simple and convenient operation and maintenance;
3、The vacuum unit adopts a stepped energy-saving mode, which increases power and operates effectively。
4、The equipment is equipped with an automatic cleaning function, which comes with a startup and shutdown operation for cleaning. The exhaust port of the pump will not have any environmental hazards such as black smoke.

After setting a set of normal vacuum ranges, when the vacuum value is greater than or equal to high vacuum degree, the screw pump operates at low frequency. When it is less than low vacuum degree, the screw pump operates at high frequency. The Roots pump adjusts the operating frequency through a pressure controller
