Pulsation of the valve stem of the diaphragm valve at the low-temperature pump outlet!

Thread Content

The outlet valve of the liquid oxygen pump in our unit is a diaphragm gate valve. During operation, it was observed that the stem of the check valve fluctuated continuously as pressure increased, when the opening degree was around 60-70%. When the rotation speed was 3600 revolutions per minute and the outlet pressure was around 6 MPa, both the outlet pressure and the stem fluctuations were significant. We are seeking solutions! Thank you for the advice!

Is the valve vibration caused by fluctuations in the pump outlet pressure?
