First, arc gear pump common faults and Countermeasures:
1, the phenomenon of failure: pump flow arc gear pump failure reasons: 1) suction or discharge valve is closed; 2) inlet pressure is low; 3) outlet pipe plugging; 4) filler box leakage; low.
Countermeasures: 1) Confirm whether the valve is closed; 2) Check whether the valve is open; 3) Check if the discharge volume is normal; 4) Tighten; .
2, the phenomenon of failure: the pump can not discharge the cause of the malfunction: a, the opposite direction of rotation; b, suction or discharge valve is closed; c, the inlet or the pressure is too low; d, viscosity is too high, the pump can not bite material.
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, low speed operation according to the speed ratio of the flow rate appears, if the flow, the inflow is insufficient.
Second, arc gear pump operation and maintenance methods are:
1, check all pipe flanges before starting, the tightness of joints.
2, disc drive coupling, no friction and collision sound.
3, the first start should be injected into the pump liquid.
4, before starting the full suction and discharge valves in the pipeline, closed valve is strictly prohibited to start.
5, verify the direction of motor rotation, start the motor.
Arc gear pump in the use of a period of time after regular maintenance and repair to ensure that arc gear pump better operation
