Common failures of water pumps and their elimination-no liquid supply, insufficient liquid supply or insufficient pressure

1) The pump is not filled with water or is not properly vented; Elimination measures: Check whether the pump casing and the inlet pipeline are all filled with liquid. 2) Speed u200bu200bis too low; Elimination measures: Check whether the motor wiring is correct, whether the voltage is normal or whether the steam pressure of the turbine is normal; 3) The system head is too high; Elimination measures: Check the system head (especially friction loss). 4) Suction range is too large 1) The pump is not filled with water or is not properly vented; Elimination measures: Check whether the pump casing and the inlet pipeline are all filled with liquid. 2) Speed u200bu200bis too low; Elimination measures: Check whether the wiring of the motor is correct, whether the voltage is normal or whether the steam pressure of the turbine is normal; 3) The system head is too high; Elimination measures: Check the system head (especially friction loss). 4) The suction lift is too high; elimination measures: check the existing net pressure head (too small or too long inlet pipeline will cause great friction loss). 5) The impeller or pipeline is blocked; elimination measures: check for obstacles. 6) The direction of rotation is wrong; elimination measures: check the direction of rotation. 7) Air is generated or the inlet pipeline is leaking; elimination measures: check the inlet pipeline for air pockets and/or air leakage. 8) The packing or seal in the stuffing box is worn, causing air to leak into the pump casing; elimination measures: check the packing or seal and replace as necessary, and check whether the lubrication is normal. 9) The suction head is insufficient when pumping hot or volatile liquids; elimination measures: increase the suction head and consult the manufacturer. 10) The bottom valve is too small; Elimination measures: Install a bottom valve of the correct size. 11) The immersion depth of the bottom valve or inlet pipe is not enough; elimination measures: consult the manufacturer for the correct immersion depth. Use baffles to eliminate turbulence. 12) Impeller clearance is too large; Elimination measures: Check whether the clearance is correct. 13) Impeller damage; elimination measures: check the impeller and replace it as required. 14) The impeller diameter is too small; elimination measures: consult the manufacturer for the correct impeller diameter. 15) The position of the pressure gauge is incorrect; elimination measures: check whether the position is correct, check the outlet nozzle or pipe
