(1) The impeller flow channel is blocked. If the impeller flow channel is blocked, it will affect the work of the impeller and cause the outlet pressure to drop. Therefore, it is necessary to remove the pump to check and remove the foreign matter. In order to prevent the recurrence of this problem, if necessary, a filter device can be added before the pump inlet. (2) internal leakage occurs when the gap between the rotating part and the stationary part of the pump exceeds the design range, it will lead to internal leakage, which is reflected in the drop of the discharge pressure of the pump, such as the gap between the impeller mouth ring and the inter-stage gap of the multi-stage pump. At this time, the corresponding disassembly and inspection shall be carried out to repair or replace the parts with excessive clearance. (3) Inlet cavitation occurs if the pump
