Arc gear pump common fault and maintenance methods
Arc gear pump failure and maintenance methods common what? As follows: (1) arc gear pump failure phenomenon: the pump can not discharge arc gear pump failure 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 Too high, the pump can not bite arc gear pump measures: a, confirm the direction of rotation; b, confirm the valve is closed; c, check the valve and pressure gauge; d, check the liquid viscosity, low speed operation by the speed ratio of the flow rate Appears, if there is flow, the inflow is insufficient, (2) circular arc gear pump failure phenomenon: insufficient pump flow circular arc gear pump failure reasons: a, suction or discharge valve is closed; b, inlet pressure is low; c, outlet pipeline plugging; d, packing box leakage; e, speed is too low arc gear pump countermeasures: a, confirm the valve is closed; b, check the valve is open; c, to confirm the discharge volume is normal; d, fastening; , Should stop running, disassembly inspection; e, check the actual speed of the pump shaft; arc gear pump operation and maintenance methods: (1) before starting to check all the pipe flange, the joint of the close Sealing. (2) Disc drive coupling, no friction and collision sound. (3) The first start should be injected into the pump liquid. (4) should be fully open before inhalation and discharge of the valve in the pipeline, closed valve is strictly prohibited to start. (5) After verifying the direction of motor rotation, start the motor. Arc gear pump in use for some time after regular maintenance and repair to ensure better pump operation.
