(1) Failure phenomenon: the pump can not discharge Fault causes: a, the opposite direction of rotation; b, suction or discharge valve is closed; c, no inlet or pressure is too low; d, viscosity is too high, the pump can not bite countermeasures: a , Confirm the direction of rotation; b, confirm the valve is closed; c, check the valve and pressure gauge; d, check the viscosity of the liquid to low-speed operation by the speed ratio of the flow rate is there, if the flow, the inflow is insufficient.
(2) Symptoms: abnormal sound failure reasons: a, coupling eccentric or poor lubrication b, motor failure; c, reducer abnormalities; d, shaft seal at the installation of bad; e, shaft deformation or wear countermeasures: a, Check or fill the grease; b, check the motor; c, check the bearings and gears; d, check the shaft seal; e, parking disintegration inspection (3) Symptom: pump flow failure Cause: a, suction or discharge valve is closed; b, the inlet pressure is low; c, the outlet pipe plugging; d, packing box leak; e, speed is too low countermeasures: a, confirm the valve is closed; b, check the valve is open; c, confirm the discharge volume is normal; Solid; a large number of leaks affect production, should stop running, demolition inspection; e, check the actual shaft speed;
(4) Fault phenomenon: the current is too large Fault causes: a, the outlet pressure is too high; b, melt viscosity is too large; c, shaft seal assembly bad; d, shaft or bearing wear; e, motor failure measures: a, check Downstream equipment and pipelines; b, test viscosity; c, check the shaft seal, appropriate adjustments; d, check after parking, hand crank car is too heavy; e, check the motor (5) Symptoms: pump suddenly stopped Cause of the malfunction: a , Power outage; b, motor overload protection; c, coupling damage; d, the outlet pressure is too high, interlocking reaction; e, bite abnormal pump; f, shaft and bearing adhesion stuck measures: a, b, check the motor; c, open the safety cover, disk inspection; d, check the instrument interlock system; e, after parking, reversing confirmation; f,
