1. Process medium relative density and viscosity index:
Processing method: check the material component to make its viscosity and relative density and design value is in line with the process operator to adjust
2. Electrical failure :
Processing method: check the circuit breaker heater setting value, check the voltage, three-phase current should be balanced, the error is not greater than 3%
3. When the pump starts, the outlet valve is open, the resistance in the outlet pipe is too small :
Processing method: the outlet valve is closed, the pump starts slowly open the outlet valve .
4. Balance tube is not smooth :
Processing method: clear the balance tube
5. Pump assembly is not good, static and dynamic part of the friction or stuck :
Treatment method: to pump the assembly, check the fit clearance, bearing clearance, mechanical seal, and so on, and strictly according to the design requirements to adjust .
