Arc gear pump common fault and maintenance methods

First, the common fault and maintenance methods 1) Symptom: The pump can not discharge Fault causes: a, the opposite direction of rotation; b, suction or discharge valve is closed; c, the inlet without material 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 according to the proportion of speed flow if there is flow, then inflow Insufficient, insufficient pump flow (2) Symptom: Insufficient pump flow Cause of malfunction: a. Suction or discharge valve is closed. B. Inlet pressure is low. C. Outlet line is blocked. D. The valve is closed; b, check the valve is open; c, confirm the discharge is normal; d, tighten; a large number of leaks affect production, should stop running, disassembly inspection; e, check the actual shaft speed; (1) Check all pipe flanges and joints before starting.
