The operating principle and advantages and disadvantages of submersible pumps

The principle of a submersible pump

A submersible pump is a pump that pumps liquid in the form of submersible, which is composed of a submersible pump body, an electric motor, a coupling and a mounting bearing. The working principle of the submersible pump is that the rotating energy of the motor is transmitted to the submersible pump body, the submersible pump body drives the impeller to rotate, and the rotation of the impeller drives the liquid to enter the impeller cavity of the pump body from the suction inlet, and in the rotation process of the impeller, the liquid is pressurized under the action of the impeller, so that the liquid is discharged from the discharge port and the pump body is realized, so as to realize the effect of pumping liquid.

Advantages of submersible pumps

1. The design structure of the submersible pump is simple, easy to maintain, can provide high-pressure flow and efficient discharge, and ensure the reliability and operability of the system;

2. The shell of the submersible pump has good anti-corrosion performance, can work stably for a long time, has strong pressure resistance, can resist high-pressure environment, impact resistance and wear resistance;

3. The pump body of the submersible pump has high strength and adopts a special strengthening design, which can resist high temperature, high pressure and complex flow environment;

4. The suction inlet and discharge outlet of the submersible pump are connected by threads, which can be quickly disassembled and replaced with pipelines to facilitate maintenance;

5. The power consumption of the submersible pump is small, small in size and light in weight, which can meet the needs of various applications and save energy.

Disadvantages of submersible pumps

1. The price of submersible pump is expensive and cannot meet the budget of most users;

2. The use of submersible pumps is noisy, and sound insulation devices need to be installed to reduce noise pollution;

3. The lubricating oil pump of the submersible pump is worn badly, which is easy to cause oil leakage and needs to be replaced regularly;

4. The impeller of the submersible pump is easy to burn out at high temperature, and a cooler needs to be installed.
