How does a vacuum pump automatically adjust the level of vacuum in response to fluctuations in inlet pressure? How to set up the control system?
A balance pipe is added between the pump’s inlet and outlet; the opening of this pipe is controlled by a diaphragm control valve based on the pressure value feedback from the inlet pressure, thereby regulating the inlet vacuum level. If the pump handles a large volume of gas, the pump’s speed can also be adjusted through frequency conversion control. The logic control diagram is shown below; some information on vacuum technology can be found on our website: www.ytskv.com
This kind of request is rarely mentioned. The principle of pressure control is the same; the common methods used are controlling the opening degree of the inlet valve, adjusting the pump’s frequency, and setting up a bypass
