(1) Symptom: Pump can not nest
Reason: a, the opposite direction of rotation; b, inhalation or discharge valve closed; c, the entrance without material or pressure is too low; d, viscosity is too high, the pump can not bite
C, check the valve and pressure gauge; d, check the liquid viscosity, at low speed when the speed ratio of the flow rate is present, if the flow, the inflow of insufficient
(2) Symptom: pump flow is insufficient
Cause: a, inhalation or discharge valve closed; b, the inlet pressure is low; c, the outlet pipeline is blocked; d, packing box leakage; e, the speed is too low
C, to confirm the discharge is normal; d, fastening; a large number of leaks affect the production, should stop running, disassembly inspection; e, check the pump shaft actual speed; a, to confirm whether the valve is closed; b, check the valve is open; ;
(3) Symptom: abnormal sound
Failure reasons: a, coupling eccentric or poor lubrication b, motor failure; c, reducer abnormal; d, shaft seal at the poor installation; e, shaft deformation or wear
Countermeasure: a, find or fill the grease; b, check the motor; c, check the bearings and gear; d, check the shaft seal; e, parking disintegration check
