1、 Overview of WQP stainless steel submersible sewage pump:

1. The WQP stainless steel submersible sewage pump adopts a large channel anti clogging hydraulic component design, greatly improving the ability of sewage to pass through. It can effectively pass through 5 times the diameter of the pump and solid particles with a diameter of about 50% of the pump diameter.

2. Reasonable design, reasonable matching motor, high efficiency, significant energy-saving effect.

3. The mechanical seal adopts a dual channel series seal, made of hard and wear-resistant tungsten carbide, which has the characteristics of durability and wear resistance, and can ensure the safe and continuous operation of the pump for more than 800 hours.

4. The pump structure is compact, small in size, easy to move, and easy to install, without the need to build a pump room. It can work underwater, greatly reducing project costs.

5. There is an oil-water probe installed in the pump oil chamber. When the mechanical seal on the pump side is damaged and water enters the oil chamber, the probe generates a signal to protect the pump.

6. A fully automatic safety protection control cabinet can be equipped according to user needs to monitor pump leakage, electric leakage, overload, and overheating, ensuring reliable and safe pump operation.

7. The dual rail automatic coupling installation system has brought great convenience to the installation and maintenance of pumps, and people do not have to enter and exit the sewage pit for this.

8. The float switch can change according to the required water level. Automatic control of pump stop and start, no need for dedicated personnel to supervise.

9. Ensure that the motor operates without overload within the range of head.

10. According to the usage scenario, the motor can adopt a water jacket external third-party circulating cooling system, which can ensure the safe operation of the electric pump in a dry state without water.

11. There are two installation methods: fixed automatic coupling installation and mobile free installation, which can meet different usage scenarios.

2、 Structural Description of WQP Stainless Steel Submersible Sewage Pump

The WQP stainless steel submersible sewage pump consists of a motor and a pump, which are separated by an oil isolation chamber and mechanical seal components. It is an electromechanical integrated product, and the motor and pump share the same shaft (rotor). The entire length of the pump is short and the structure is compact. Equipped with multiple protective devices to ensure reliable operation of the pump, its main components function as follows:

Signal line 1: Equipped with a fully protected water pump control cabinet to provide comprehensive protection for the pump, including leakage, phase failure, short circuit, overheating, motor overload, and other items Motor stator 8: adopts B-level or F-level insulation.

Leakage probe 11: This component is installed in the oil chamber. When the mechanical seal is damaged and water enters the oil chamber, the probe can send a signal to the control system to protect the pump.

Mechanical Seal 13: Adopting a dual channel series seal and using a new type of hard and corrosion-resistant tungsten carbide material, it has the characteristics of reliable sealing, wear resistance, and long service life.

Impeller 17: The impeller adopts a single channel or double channel structure, which has strong passing capacity and can pass large materials and fiber garbage, reducing blockage and entanglement failures.

Pump body 15: Paired with the impeller, the pump has high efficiency.

Sealing ring 18: installed at the mouth ring of the pump body. When the impeller wears out the mouth ring due to operation, the sealing ring can be replaced to ensure optimal efficiency of the pump operation.
