What are the scope of use and product features of explosion-proof submersible pumps?


    Explosion-proof submersible pumps are suitable for the transportation of granular sewage in the chemical, petroleum, pharmaceutical, mining, paper, cement, steel, power, coal processing, and urban sewage treatment plant drainage systems, municipal engineering, construction sites, etc. Dirt, stainless steel explosion-proof submersible pumps can also be used to pump clean water and corrosive media.

What problems must be paid attention to during the use and maintenance of deep well submersible pumps?

(1) The submersible pump cannot be dehydrated. Test run under anhydrous conditions, the time must not exceed 5 minutes. In the process of pumping, if the water level is not reduced, it must be noted that the pump body should not be exposed to the surface.

(2) After the submersible pump is stopped, it cannot be restarted immediately. It must be started after the return of the stored water in the pipe is completed. If water cannot be discharged after starting, stop the machine immediately and find out the cause and eliminate it.

(3) Different types of submersible pumps shall be used according to the specified head; the inner diameter of the matching rubber pipe, iron pipe or canvas pipe shall meet the technical requirements.

(4) When the submersible pump is put into the water or raised to the surface of the water, the rope on the "ears" must be pulled, and the cable must not be pulled. To handle, disassemble, or overhaul, turn off the power.

Explosion-proof submersible sewage pump mainly has several product features:

1. It adopts the unique single-blade or double-blade impeller structure, which greatly improves the dirt passing ability, and can effectively pass the fiber material with the diameter of the pump 5 times and the solid particles with the diameter of the pump diameter of about 50%.

2. The mechanical seal adopts a new type of hard and corrosion-resistant tungsten carbide as the material, and at the same time, the seal is improved into a double-end seal, so that it can be operated in the oil chamber for a long time, and the pump can be safely operated continuously for more than 9000 hours.

3. It can be equipped with automatic safety protection control cabinet according to user's needs to absolutely protect the pump from water leakage, leakage, overload and over temperature, thus improving the safety and reliability of the product.

4, the beginning of the float can automatically control the start and stop of the pump according to the required liquid level change, no need for special care, easy to use.

5, according to the needs of users with dual-rail automatic coupling installation system, it brings great convenience to installation and maintenance, people do not have to enter the sump for this purpose.

6. The overall structure is compact, small in size, small in noise, remarkable in energy saving effect, easy to overhaul, no need to build a pump room, and can work in submerged water, greatly reducing the project cost.

7. The high-precision anti-interference water leakage detecting sensor is installed in the sealed oil chamber, and the heat-sensitive components are embedded in the stator winding to absolutely protect the pump motor.
