Arc gear pump failure phenomenon and solutions
Arc gear pump failure phenomenon and solutions: (1) circular arc gear pump common stuck problem causes of failure: a, the opposite direction of rotation; b, suction or discharge valve is closed; c, the inlet without material or pressure is too low; d , The 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 liquid viscosity to low speed operation by the speed ratio of the flow appears, If there is flow, the inflow is insufficient, (2) arc gear pump fault phenomenon: insufficient pump flow Failure causes: a, suction or discharge valve is closed; b, the inlet pressure is low; c, outlet pipeline plugging; d, e, speed is too low countermeasures: a, to confirm whether the valve is closed; b, check the valve is open; c, to confirm the discharge is normal; d, fastening; leaks affect a large number of production should stop running, demolition inspection; Check the actual speed of the pump shaft; (3) Symptom: abnormal sound Fault causes: a, coupling eccentric or poor lubrication b, motor failure; c, reducer abnormalities; d, arc gear pump shaft seal installed poor; e, shaft deformation or wear
