When the pump works, the liquid at the inlet of the turbine will produce liquid vapor under a certain vacuum pressure. The vaporized bubbles will detach from the impeller and other metal surfaces under the impact of liquid particles, thereby damaging the system. impeller and other metal surfaces and causing peeling.
1. Reason: There may be water accumulation inside the pump body, which will cause the temperature inside the pump body to increase, thereby causing the temperature at point d2 to increase.
2. There may be dirt inside the pump body, which may cause the internal temperature of the pump body to increase, thereby causing the temperature to rise at point d2 5.
