How to repair the water pump? It can be seen from the pump repair diagram below

Pump

It can be repaired if it breaks, such as water pump leakage, water pump leaf rotation and so on. The pump leakage is likely to be a non -tight cause of the nuts during installation. If the leakage is not serious, you can apply cement or cement slurry where the leakage is leaked. The pump leaf rotation is relatively light with a honeycomb to perform the pump leaf rotation.

Pump repair method

The pump cannot be started

Reason: The filler is too tight or the impeller and the pump are blocked by the accumulation of debris; the bearings, pump shafts, leak -reducing rusts; severe bending of the pump shaft, and so on.

Maintenance method: Relax the filler, dredge the drinking sink; remove the pump body to remove and clear the debris, and carry out rust removal; remove the pump shaft for correction or replace the new pump axis.

Insufficient traffic

Reason: In most cases, due to the leakage and bottom valve leakage of the water absorption pipe; the water inlet is blocked; the depth of the bottom valve is insufficient; the speed of the water pump is too low;

Maintenance method: View water absorption pipe and bottom valve to block the gas leakage source; remove the silt or block at the water inlet; the depth of the bottom valve into the water needs to be greater than 1.5 times the diameter of the water inlet pipe, and the depth of the bottom valve into the water increases; view After the power supply voltage increases the speed of the pump, the sealing ring or the impeller is replaced; the installation position of the pump is reduced before replacing the high -rise pump.

Unable to suck water

Reason: There are air or water inlet pipes in the pump body, or the bottom valve is not closed, and the water is insufficient. The vacuum pump filler leaks, and the gate valve or valve is closed.

Maintenance method:

1. First put the water pressure, then fill the pump body with water and then boot. At this time, check whether the inverse valve is tightly, the pipeline and the connector are leaked. If you find that the air leakage can be applied to the lubricating oil or blended the paint at the joint and tighten the screw.

2. Check the oil seal ring of the pump axis. If the wear is severely, the new accessories should be replaced.

3. The pipe is leaking or air. It is very likely that the nuts are not tightly twisted during installation. If the leakage is not serious, you can apply cement or asphalt oil to mix and mix the cement slurry where the air leakage or leaks. Temporary repair can apply some wet mud or soft soap. If you leak water at the connector, you can tighten the nut with a wrench. If the leakage is severely needed to be re -disassembled, the tube with cracks is replaced; the raising journey is reduced and the pump’s mouth is pressed to 0.5mm underwater.

Water pump does not get out of water

Reason: The pump body and the water absorption pipe are not filled with water diversion; the water level is lower than the water pump filter pipe; the water absorption pipe is ruptured.

Maintenance method: After the failure of the bottom valve is eliminated, the water diversion is filled; the installation position of the pump can be reduced to ensure that the water filter pipe is pumped at the water level or waited for the water level. Or replace.

Vibration or noise occurred in the pump body

Reasons: The water pump is not firm or the pump is too high; the motor drum bearing is damaged; the spindle of the pump is bent or the motor spindle is different or uncomfortable.

Maintenance method: stabilize the water pump or reduce the installation of the water pump; replace the drum bearing of the motor; correction or adjust the relative position of the water pump and motor.

Too much power consumption

Reason: The speed of the pump is too high; the spindle of the water pump is bent or the spindle of the pump and the motor axis is different or uncomfortable; it is not appropriate to choose the water pump; the water pump is inhaled or the block;

Maintenance method: Check the circuit voltage to reduce the speed of the pump; correct the pump’s spindle or adjust the relative position of the pump and motor; select the appropriate raising water pump; clean the sediment or block; replace the drum bearing of the motor.
