Submersible pumps are generally composed of water pumps, submersible motors, cables, water pipes and control switches. Its structure is relatively simple, and it is also easy to disassemble when repairing it.

Usually, replacing a submersible pump requires following a series of clear steps to ensure safety and efficiency. The following are the detailed steps for replacing a submersible pump:

Preliminary preparation

1. Check equipment and tools:

• Make sure that all required equipment and tools are complete and in good condition.
• Common tools include wrenches, ladders, lifting equipment, etc.

1. Confirm the model and technical parameters of the submersible pump:

• According to the model and technical parameters of the submersible pump being replaced, choose a suitable replacement.

1. Turn off the power:

• During operation, make sure that the power of the submersible pump is turned off and the equipment is in a power-off state.

1. Arrange personnel and safety protection:

• Reasonably arrange personnel to ensure high efficiency and safety of operations.
• Operators need to wear necessary safety protection equipment, such as helmets, gloves, etc.

1. Remove surrounding debris:

• Remove debris around the submersible pump to ensure a clean working space.

1. Check the installation environment:

• Check the installation environment to ensure that the equipment can be accurately and safely installed and used.

Disassemble the original submersible pump

1. Ensure power is off:

• Confirm again that the submersible pump is powered off before disassembly.

1. Drain the pump:

• If there is liquid in the pump, drain it first.

1. Remove the connecting bolts:

• According to the installation method of the submersible pump, remove the connecting bolts and separate the pump body from the pipeline.

1. Remove the cable connection:

• Remove the cable connection of the submersible pump to ensure that the submersible pump can be completely disconnected from the power supply.

1. Remove the submersible pump:

• According to the installation location and structure of the submersible pump, take appropriate measures to remove the submersible pump and move it away from the site.

Install the new submersible pump

1. Install the pump body:

• According to the model and technical parameters of the new submersible pump, select an appropriate location to install the pump body in the appropriate position.

1. Connect the pipeline:

• Connect the new submersible pump to the pipeline and ensure that the connection is firm to avoid leakage.

1. Connect the cable:

• Connect the cable of the submersible pump and ensure that the circuit is normal to avoid short circuit.

1. Reset the submersible pump:

• Adjust the position of the submersible pump to ensure that the pump body is in the appropriate position.

Later work

1. Trial run:

• Put the submersible pump in the water, making sure that the motor part is not immersed in the water.
• Turn the rotor of the submersible pump several times to remove debris in the pump.
• Turn on the power and start the motor to test the pump.
• After confirming that there is no abnormality in the trial run, the submersible pump can be used normally.

1. Clean the base:

• After the replacement is completed, clean the base of the original equipment to ensure that the new pump can be placed accurately.

1. Fixing and installation inspection:

• Check the fixing and installation of the submersible pump to ensure safety and normal operation.
