Seven tips and troubleshooting for submersible pump
1. The submersible pump should check the insulation resistance of the submersible pump at intervals of 0.5MΩ before use. If it does not meet the requirements, it should be dried.
2, before use, check cables, switches, electric shock protectors, switches and other electrical appliances should work normally, the cable is not damaged, and pay attention to carefully identify the cable. The yellow and green two-color lines are grounded to prevent electric shock and electric shock.
3. Regularly check the drain hole and drain hole. Tighten if there is no abnormality.
4. When the submersible pump enters the water or the water, the TSWA horizontal multistage pump must first cut off the power supply, and then pull the rope on the ring, absolutely pull the cable
5. The submersible pump can't be buried in the river mud. If there are more water and debris in the water, put the submersible pump into the basket or the basket, then put the basket or basket into the water.
6. When the submersible pump is tested outside the water (for example, to determine the steering), it must not exceed 5 minutes to prevent the motor from burning out.
7. After the submersible pump has been working for 300h, it should be tested for sensitive water. If the water or oil-water mixture is less than 25mL, it can be used continuously. Otherwise, check whether the block and rubber seal are damaged.
The water leakage fault of the submersible pump is mostly caused by the aging and wear of the sealing device. In addition to replacing the new seal, the following simple troubleshooting methods can be adopted.
The submersible pump seal ring loses its elasticity due to long-term use. At this time, the seal ring can be taken out, and then a piece of paper or cloth with a thickness of 0.3 to 0.5 mm is cut into a groove slightly larger than the original seal ring. Finally, Install the original seal.
The rubber seal ring in the nylon seal seat of the submersible pump is worn out, and the seal ring can be taken out and replaced. If the fastening spring on the seal ring loses elasticity or breaks, the spring can be removed and the wire or wire with a suitable diameter can be used. tight.
The first seal ring of the submersible pump is severely worn. The nylon seal ring can be taken out, and the asbestos rope coated with butter is wound on the stainless steel sleeve to fill it slightly higher than the original nylon seat, then filled with butter, and then the nylon seat is tightened with bolts. Compaction.
The submersible pump seal box and the cast iron seal ring lose their elasticity. The seal ring can be taken out from the cast iron tank. Find a piece of cardboard with a thickness of six to one millimeter and cut it into the same size, pad in the groove, and then seal it. Put in the circle.
If the rubber seal of the submersible pump oil hole is damaged, you can find a piece of tape, cut it into a hole slightly larger than the bolt, add a flat pad on the upper side, and put it in the oil hole of the bolt together.
