Gear pump common fault and troubleshooting:
1, the cause of the malfunction: a, rotating in the opposite direction; 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 material.
2, troubleshooting: 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 is there, if the flow, then inflow insufficient.
Symptom two: insufficient pump flow:
1, the cause of the malfunction: a, suction or discharge valve is closed; b, the inlet pressure is low; c, the outlet pipe plugging; d, packing box leakage; e, speed is too low.
2, troubleshooting: a, to confirm the valve is closed; b, check the valve is open; c, to confirm the discharge is normal; d, tighten; a large number of leaks affect production, should stop running, disassembly inspection; Actual shaft speed
Symptom three: abnormal sound:
1, the cause of the malfunction: a, coupling eccentric or poor lubrication b, motor failure; c, reducer abnormalities; d, shaft seal at the installation of bad; e, the shaft deformation or wear.
2, troubleshooting: a or find filling grease; b, check the motor; c, check the bearings and gears; d, check the shaft seal; e, parking disintegration inspection.
Symptom four: the current is too large:
1, the cause of the malfunction: 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. The valve inlet pump industrial washing machine 2, troubleshooting: a, check the downstream equipment and pipelines; b, test the viscosity; c, check the shaft seal, appropriate adjustments; d, check after parking, hand crank car is too heavy; .
Symptom five: pump suddenly stopped:
1, the cause of the malfunction: a, power failure; b, motor overload protection; c, coupling damage; d, the outlet pressure is too high, interlocking reaction; e, abnormal bite into the pump; f, stuck shaft and bearing stuck.
2, troubleshooting: a, check the power; b, check the motor; c, open the safety cover, disk inspection; d, check the instrument interlock system; e, after parking, reversing confirmation; f,
