1, submersible pump from time to time (about 1000h), before use to check the submersible pump insulation resistance, should not be less than 0.5MΩ, if not required, then to be dried.

2, before use to check the cables, switches, electric shock protector, switches and other electrical appliances should work properly, the cable is not damaged, and pay attention to carefully identify the cable. Yellow and green two-color line for the ground line, to prevent leakage electric shock accident.

3, regularly check the drain hole and drain hole. Tighten if there is no abnormality.

4, submersible pump into the water or water, TSWA horizontal multistage pump will be awarded the first cut off the power, and then pull the rope tied to the rings, the cable can pull absolutely 5, the submersible pump can not be buried in the river 怍 怍, If the water is more debris in water, the submersible pump should be placed in a basket or basket, then the basket or basket into the water 6, the submersible pump test machine outside the water (such as in order to determine the steering), shall not exceed 5min , To prevent the motor heat burn 7, submersible pump 300h after work, to conduct a sensitive water inspection, if the release of water or oil-water mixture is less than 25mL, you can continue to use, or to check the block and the rubber seal is damaged submersible pump Leakage failure Submersible pump leakage Mostly due to sealing device aging, wear and tear, in addition to the replacement of the new seal, but also can take the following simple exclusion method Submersible pump seals due to long-term use of the loss of elasticity, then remove the seal, and then find 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 sealing ring and finally fitted with the original sealing ring.

Submersible pump Nylon sealing seat within the rubber seal wear, the seal can be removed, and then exchange the location of installation, such as the sealing ring on the fastening spring loses its elasticity or fracture, you can remove the spring, with a suitable diameter wire or wire tight.

Submersible pump first seal ring serious wear and tear can be removed nylon ring, and then coated with asbestos butter butter, wrapped in stainless steel wrap to slightly higher than the original nylon seat, and then fill the butter, and then nylon seat with a bolt Compaction.

Submersible pump seal box and cast iron between the ring of elasticity, can be removed from the cast iron ring groove, find a piece of hard cardboard 1-6 mm thick cut into the same size, pad in the groove, and then seal Circle into.

Submersible pump oil hole rubber ring damage, find a piece of tape, cut into holes slightly larger than the bolt, plus flat pad above, together set in the bolt into the hole.
