Why does the Cryostar liquid oxygen pump stop generating pressure suddenly during operation, and how should it be handled?
Thread Content
During operation, our company’s liquid oxygen pump suddenly experienced a drop in pressure and current; its speed was 3200 rpm. The pump was stopped to check the filter, and the inlet was reconnected to the main cooling exhaust pipe, but the problem persisted. No abnormalities were found in the pump itself. What could be the cause? There was liquid in the exhaust pipe of the pump at the beginning of operation, but it disappeared after the pump started running – why then did the pressure and current drop?
When the discharge of the pump is increased, there is no air in it, and the pressure is normal! What’s the reason?
