Sewage treatment plant sludge through wall pump

sludge return pumpMain structure:

1. Cable: The cable adopts a specially designed waterproof cable;

2. Junction box: The junction box is fully closed and isolated from the surrounding liquid and stator box;

3. Motor: squirrel cage 3-phase submersible asynchronous motor, F-class insulation, protection level IP68. The motor is cooled by the surrounding medium;

4. Shaft: The shaft of the electric motor is made of stainless steel material, and the rotor undergoes dynamic balancing experiments;

5. Sealing: The static seal is an O-ring seal. The shaft seal is a mechanical seal that isolates the oil chamber from the surrounding medium;

feature：

　　The submersible pump based on the principle of submersible operation is characterized by high flow rate and low head, with a flow rate of tens of thousands of cubic meters per hour and a head not exceeding20Rice. The motors are all multi pole motors with low rotational speeds. The installation methods are mostly wellbore type and sled type, commonly used in pump stations and known as flood discharge tools!

The pump is coaxial, and the motor is a dry fully enclosed submersible three-phase asynchronous motor.

The reflux pump uses dual, triple mechanical seals and auxiliary sealing structures,FGrade insulation, protection levelIP68And seal leakage, winding and bearing temperature rise, junction box and oil chamber water inlet detection devices are installed inside the motor. All detection signals are centrally fed back to a submersible pump protector on the electrical control cabinet for monitoring, and sound and light alarms are triggered in case of faults. To ensure the normal operation of the positive pump.

Due to the integration of the submersible axial flow pump motor and water pump, the installation height is reduced and the weight of the unit is reduced compared to traditional pumps40%Without the need for labor-intensive and time-consuming axis alignment processes on site, on-site installation is very convenient2-3A complete set of electric pumps can be installed within an hour.

There are various installation methods for this product, including suspended installation, floor standing installation, diagonal installation, open installation, etc.

The use of this type of submersible electric pump is a complete solution to building pump stations in areas with large water level fluctuations along rivers and lakes, and to achieve complete motor flood control. It also eliminates the long axis and intermediate bearings between the pumps, making the operation of the unit doubly reliable.

Submersible axial flow pump: The electric motor driving the water pump is a dry fully enclosed submersible three-phase asynchronous motor, which can operate in water for a long time and has a series of advantages over traditional units.

Submersible sludge reflux pump

It is necessary to work underwater; Cannot work in environments with flammable, explosive, or highly corrosive liquids; The steel expansion bolt must be fixed as required, and after installation, the cable must be tightened and fixed securely.

When selecting, it is necessary to determine the density and acidity of the water in the pool, which should not exceed the rated parameters. If exceeded, it cannot be used in such an environment, which will cause the motor to overload and burn out the cable. The cable surface should not be damaged, and if damaged, the power should be immediately turned off to replace the cable. If not replaced in time, water can flow from the damaged cable to the inside of the motor, which can also cause the motor to burn out.
