Common faults and elimination of water pumps-no liquid supply, insufficient liquid supply or insufficient pressure
1) The pump is not filled with water or properly vented;
Remedy: Check that the pump casing and inlet line are completely filled with liquid.
2) The speed is too low;
Elimination measures: Check whether the wiring of the motor is correct, the voltage is normal or the steam pressure of the turbine is normal;
3) The system head is too high;
Elimination measures: Check the head of the system (especially friction loss).
4) The suction stroke is too high;
Elimination measures: Check the existing net head (inlet pipeline is too small or too long will cause a lot of friction loss).
5) The impeller or pipeline is blocked;
Elimination measures: Check for obstacles.
6) The direction of rotation is wrong;
Remedy: Check the direction of rotation.
7) There is leakage of air or inlet pipeline;
Elimination measures: Check the inlet pipeline for cavitation and / or air leakage.
8) The packing or seal in the stuffing box is worn out, causing air to leak into the pump casing;
Elimination measures: Check the packing or seal and replace as necessary, check whether the lubrication is normal.
9) Insufficient suction head when pumping hot or volatile liquids;
Elimination measures: increase the suction head, consult the manufacturer.
10) The bottom valve is too small;
Elimination measures: Install the correct size foot valve.
11) The immersion depth of the bottom valve or inlet pipe is not enough;
Elimination measures: Consult factory for correct immersion depth. Use baffles to eliminate eddy currents.
12) The impeller clearance is too large;
Elimination measures: Check whether the gap is correct.
13) Impeller damaged;
Elimination measures: Check the impeller and replace it as required.
14) The impeller diameter is too small;
Elimination measures: Consult factory for correct impeller diameter.
15) The position of the pressure gauge is incorrect;
Elimination measures: Check the correct position, check the outlet nozzle or pipeline
