1、This equipment is a multi unit vacuum system equipment developed by our company, which provides vacuum extraction for the operation of on-site workshop immersion machines Empty function, which allows for the free setting of operating parameters within the vacuum range, enabling the vacuum system to operate and match on-site to the fullest extent possible In good condition, meeting the workshop's requirements for the 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 emission。

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