In daily use, if the operation of the high-temperature gear pump is improperly used, the management is not in place, not only can not exert its performance, and even cause sudden damage of the high-temperature gear pump.
Dalan Motor tells you that the common faults and countermeasures of high temperature gear pumps are as follows:
1, the pump can not discharge
main reason:
a, the direction of rotation is opposite;
b, the suction or discharge valve is closed;
c, the inlet is not material or the pressure is too low;
d, the viscosity is too high, the pump can not bite.
Responses:
a, confirm the direction of rotation;
b. Confirm that the valve is closed;
c. Check the valve and pressure gauge;
d. Check the viscosity of the liquid. If the flow rate is proportional to the speed at low speed, if there is flow, the flow will be insufficient.
2, the pump flow is insufficient
main reason:
a, the suction or discharge valve is closed;
b, the inlet pressure is low;
c. The outlet pipeline is blocked;
d, the stuffing box leaks;
e, the speed is too low.
Responses:
a, confirm whether the valve is closed;
b. Check if the valve is open;
c. Confirm whether the discharge is normal;
d. Fastening; when a large number of leakage leaks affect production, stop operation and disassembly inspection;
e. Check the actual speed of the pump shaft.
3, the sound is abnormal
main reason:
a, the coupling is eccentric or poorly lubricated;
b, motor failure;
c, the speed reducer is abnormal;
d, poor installation of the shaft seal;
e, the shaft is deformed or worn.
Responses:
a, find or fill the grease;
b. Check the motor;
c. Check bearings and gears;
d. Check the shaft seal;
e, parking disassembly check.
4, the current is too large
main reason:
a, the export pressure is too high;
b, the melt viscosity is too large;
c, poor shaft package;
d, shaft or bearing wear;
e, the motor is faulty.
Responses:
a. Check downstream equipment and pipelines;
b, test viscosity;
c. Check the shaft seal and adjust it properly;
d. Check after parking, whether the handcart is too heavy;
e. Check the motor.
5, the pump suddenly stops
main reason:
a, power outage;
b, motor overload protection;
c, the coupling is damaged;
d, the outlet pressure is too high, interlocking reaction;
e, the bite in the pump is abnormal;
f. The shaft and the bearing stick to each Other.
Responses:
a, check the power supply;
b. Check the motor;
c. Open the safety cover and check the car;
d. Check the instrument interlocking system;
e, after parking, positive reversal confirmation;
f, confirm the car.
