Sewage self-priming pumpIt is a hybrid system that combines self-priming and non clogging discharge, using axial reflux and passing through the pump body The design of the impeller flow channel allows for the removal of large solid particles and long fiber impurities without the need for a bottom valve or inlet water like a typical self-priming water pump.

Compared with similar domestic products, sewage self-priming pumps have the characteristics of simple structure, good self-priming performance (self-priming height can reach 5m), strong sewage discharge capacity, energy saving, and easy maintenance. All technical indicators are at an advanced level domestically. Has broad prospects for application market development.

　　Sewage self-priming pumpProduct advantages:

1. Strong sewage discharge capacity: The special impeller anti blocking design ensures that the pump is unobstructed.

2. Energy saving: Adopting a hydraulic model, the efficiency is 3-5% higher than that of a typical self-priming pump.

3. Good self-priming performance: The self-priming height is 1 meter higher than that of a typical self-priming pump, and the self-priming time is shorter.

It is necessary to understand some common faults and troubleshooting methods when using sewage self-priming pumps,

Fault phenomenon of sewage self-priming pump:

1. The motor of the sewage self-priming pump is running normally, but the water output is low or not at all.

2Sewage self-priming pumpThe casing is electrified.

Exclusion method:

1. In this situation, the sealing of the sewage self-priming pump should be checked first. During the inspection, the power plug should be unplugged, the suction port should be blocked by hand, the water pump should be filled with water, and the outlet should be held with the mouth to blow air hard into it. Observe whether the pump head leaks water, which is the damaged seal. Common faulty parts include the suction port pad, outlet pad, and impeller cover pad, which should be replaced during maintenance. If there is no phenomenon of full water, it is mostly due to damage to the impeller, corrosion and wear of the water blocking inner wall between the suction chamber and the discharge chamber, flattening of the pump head water blocking wall, and increased gap between the impeller and the pump casing. The impeller and pump casing should be replaced. When replacing the impeller, attention should be paid to removing the residual copper blades inside the pump to avoid damaging the new impeller again.

2. Most of them areSewage self-priming pumpThe water seal is damaged, and water seeps into the motor through the motor shaft, deteriorating the insulation performance of the motor. It can be repaired by replacing the water seal, drying the motor, and other methods. It should be noted that due to long-term contact with water and outdoor work, the insulation performance of the water pump is easily deteriorated by moisture. In order to ensure personal safety, the electric sewage self-priming pump should be reliably grounded.
