Installation of 4 INCH SUBMERSIBLE ELECTRIC WATER PUMP products is an important part, so it is necessary to have a detailed understanding of the installation steps of submersible pumps.

1. Check carefully before installation

4 INCH SUBMERSIBLE ELECTRIC WATER PUMP products Before installation, first check whether the pump shaft rotates flexibly. If you find that the pump shaft does not rotate flexibly, there is a knocking sound, and the pump shaft shakes radially, you should eliminate the fault before installing. Secondly, check whether the water inlet hose is damaged, and repair it in time if there is any crack. Third, check whether the fastening bolts are loose, and tighten the loose bolts.

2. Correct power distribution

4 INCH SUBMERSIBLE ELECTRIC WATER PUMP products The power line should be selected according to the regulations, the cable should be overhead, and the power line should not be too long. If the distance between the power supply and the water pump is long, the cross-sectional area of ​​the wiring cable should be appropriately increased, and the number of joints should be as few as possible. , to reduce line voltage drop.

3. There must be two-level leakage protection measures

In order to ensure safety, a metal rod with a length of more than 1 meter can be buried in the wet ground near the power supply or water pump as the grounding body of the submersible pump. At the same time, a leakage protector must be installed. Because 4 INCH SUBMERSIBLE ELECTRIC WATER PUMP products work underwater, it is easy to leak electricity and cause power loss or even electric shock accidents.

4. Check the rotation direction of the motor before entering the water. Because there are many types of submersible pumps that can discharge water when they are forward and reverse, but the water output is small and the current is large when the reverse is reversed. If the reverse time is long, the motor winding will be damaged. Therefore, before the submersible electric pump enters the water, first connect the power supply to check whether the direction of rotation is correct.

5. Set up safety warning signs

To prevent accidents, clear warning signs should be placed near 4 INCH SUBMERSIBLE ELECTRIC WATER PUMP products. For the sake of safety, it is strictly forbidden for people and livestock to touch the source of the submersible pump near the outlet of the submersible pump.
