How to use the submersible pump correctly?

1. Use of submersible pump

(1) Check whether there are cracks in the casing of the submersible pump. If there is a crack, it cannot be used.

(2) Check whether the vent hole, water drain hole, oil drain hole and the seal at the cable joint of the submersible pump are loose, and must be tightened if they are loose.

(3) Check the insulation resistance of the submersible pump. Use a 500V insulation resistance meter to test, and the insulation resistance should not be less than 5MΩ. If it is lower than this value, open the water and vent holes, dry or sun dry before use.

(4) The cable of the submersible pump is best not to have connectors. If there are connectors, they should be wrapped up. The entire cable should be free from damage or breakage. Otherwise, the cable should be replaced with a new one. In addition, the cable should be overhead and not too long.

(5) Correct the positive and negative poles of the power supply before starting to prevent the water pump from turning upside down and no water flow.

(6) Perform a comprehensive inspection of the power supply circuit and switch before starting the machine, and leave it on the ground for 3 to 5 minutes if it is running normally, then put it in the water and put it into use.

1, the submersible pump can not dehydrate operation. The test run shall not exceed 5 minutes in anhydrous condition. In the pumping process, if the water level drops continuously, it is necessary to pay attention not to let the pump body work out of the water.

2. The submersible sewage pump can not be started immediately after stopping. It can only be started after the backflow of the stored water in the pipe is completed. If there is no water after starting, stop the machine immediately to find out the reason and eliminate it.

3, should be used near the specified head; The inner diameter of rubber pipe, iron pipe or canvas pipe should meet the technical requirements.

4. When the submersible pump is put into the water or put out of the water, the lifting rope must be pulled and the cable must not be pulled. If you want to carry, disassemble or repair, should first cut off the power supply.

5. The diving depth of the submersible sewage pump is generally 0.5 to 3.0 meters. When the submersible pump dives into the water, it should be vertically lifted, not recuperate, but not trapped in the mud.

6. The submersible pump should not be started frequently, and should not be used for drainage and irrigation of water with high sediment content or mud water. When the pump can be used outside the bamboo net or wire mesh live, in order to prevent water weeds clogging submersible pump grid or mobil honda accord stuck pump impeller.

7. After starting the machine, if the impeller reverses (at this time, the water output is greatly reduced or no water), it should be stopped immediately, and any two phases of the three-phase core wire in the cable should be replaced to make it turn to water.

8, the submersible pump can be controlled by the pump control cabinet. In the absence of such equipment, a three-phase knife switch may be used, provided that a 6 ampere electric fuse is installed.
