When there is a problem with the pump, check the power supply status first:
1丶 Connector connection is reliable
2丶Is the switch contact tight?
3丶Fuse is blown
4丶 Whether the three-phase power supply is missing phase
If there is an open circuit, poor contact, blown fuse, or missing phase, the cause should be identified and repaired in time.
Daily maintenance and troubleshooting methods for pumps Water supply, more energy-efficient water supply equipment does not have the above conditions, to see if it is a mechanical failure of the pump itself.
Illness 1, the pump can not start
Common causes: the packing is too tight or the impeller and the pump body are blocked by the accumulation of debris; the pump shaft, the bearing, the leak-reducing ring are rusted; the pump shaft is severely bent.
Remedy: loosen the packing, dredge the draft water tank; disassemble the pump body to remove debris and rust; remove the pump shaft to correct or replace the new pump shaft.
Illness 2, insufficient traffic
Causes: Most of the suction pipe leaks, the bottom valve leaks; the water inlet is blocked; the bottom valve has insufficient water depth; the pump speed is too low; the seal ring or impeller wears too much; the water absorption height exceeds the standard.
Remedy: Check the suction pipe and the bottom valve to block the leaking gas source; clean the sludge or blockage at the water inlet; the depth of the bottom valve must be greater than 1.5 times the diameter of the inlet pipe, increase the depth of the bottom valve; check the power supply voltage. Increase the pump speed, replace the seal ring or impeller; lower the pump installation position, or replace the high lift pump.
Illness 3, can't suck water
Causes: There is air in the pump body or gas in the inlet pipe, or the bottom valve is not tightly closed, the water is not filled, the vacuum pump packing leaks badly, and the gate valve or the door is not closed tightly.
Method of exclusion:
1. Press the water up first, then fill the pump with water and turn it on. At the same time, check whether the check valve is tight, and whether the pipeline or joint is leaking. If air leakage is found, apply lubricant or blend paint at the joint after tightening, and tighten the screw.
2. Check the oil seal ring of the pump shaft. If the wear is serious, replace the new one.
3. The pipeline leaks or leaks. The nut may not be tightened when it is installed. If the leakage is not serious, apply cement in the place where the air leaks or leaks, or apply the cement slurry mixed with asphalt oil. Temporary repairs can be applied to wet mud or soft soap. If water leaks at the joint, the nut can be tightened with a wrench. If the water leakage is serious, it must be disassembled and replaced with a cracked pipe. Lower the lift and press the nozzle of the pump into the water 0.5m.
