1、 Overview of QWB Explosion proof Sewage Pump

Explosion proof sewage pumps are suitable for the chemical, petroleum, pharmaceutical, mining, paper industry, cement plants, steel mills, power plants, coal processing industry, as well as urban sewage treatment plant drainage systems, municipal engineering, construction sites and other industries that transport granular sewage and waste. They can also be used to pump clean water and corrosive media. The submersible pump adopts a structure and a new type of mechanical seal, which can effectively transport solid materials and long fibers. Compared with traditional impellers, the explosion-proof water pump impeller adopts a single channel or double channel form, which is similar to a curved pipe with the same cross-sectional size and has good overcurrent performance. Coupled with a reasonable volute chamber, the submersible sewage pump has high efficiency, and the impeller has undergone dynamic and static balance tests, making the pump operate without vibration. Explosion proof submersible pumps are a new generation of pump products that have been successfully developed based on the introduction of foreign technology and combined with the usage points of domestic water pumps. They have energy-saving effects, anti winding, non clogging, automatic installation, and automatic control. It has advantages in the discharge of solid particles and long fiber waste.

2、 QWB explosion-proof sewage pump product points

1. The explosion-proof sewage pump adopts a single blade or double blade impeller structure, which greatly improves the ability of pollutants to pass through, and can effectively pass through fiber materials that are 5 times the diameter of the pump

Solid particles with a pump diameter of approximately 50.

2. The mechanical seal of the explosion-proof sewage pump adopts a new type of hard and corrosion-resistant tungsten carbide material, and the seal is improved to a double end face seal, allowing it to operate in the oil chamber for a long time,

Can make the pump run continuously for more than 8000 hours.

3. Explosion proof sewage pump has a compact overall structure, small volume, low noise, energy-saving effect, easy maintenance, no need to build a pump room, can work underwater, greatly reducing

Engineering cost.

4. The explosion-proof sewage pump is equipped with high-precision anti-interference leakage detection sensors in the sealed oil chamber, and thermal sensitive components are embedded in the stator winding to detect water leakage in the pump motor

Protection.

5. Explosion proof sewage pumps can be equipped with protective control cabinets according to user needs to protect the pump from water leakage, electric leakage, overload, and overheating, thereby improving production efficiency

The quality and nature of the product.

6. The floating ball of the explosion-proof sewage pump can automatically control the start and stop of the pump according to the required liquid level changes, without the need for dedicated personnel to supervise, and is convenient to use.

7. Explosion proof sewage pumps can be equipped with a dual rail automatic coupling installation system according to user needs, which brings great convenience to installation and maintenance, and people do not have to enter the sewage for this purpose

Pit.

8. Explosion proof sewage pumps can be used within the full head range while ensuring that the motor does not overload.

9. There are two different installation methods for explosion-proof sewage pumps: fixed automatic coupling installation system and mobile free installation system.

10. The mobile explosion-proof sewage pump is suitable for frequent movement or temporary emergency situations. It does not need to be fixedly installed. Simply put on a rubber pipe, connect the pipe, and place the pump under the water to level it.

3、 Service conditions for explosion-proof sewage pump

The medium temperature of the explosion-proof sewage pump shall not exceed 60 ℃, the medium density shall be 1-1.3kg/dm3, and the pH value shall be within the range of 5-9.

Explosion proof sewage pump without internal self circulation cooling system, with the motor part exposed to the liquid level not exceeding 1/2.

The main component material of the explosion-proof sewage pump is cast iron, so it cannot be used for pumping highly corrosive liquids. Explosion proof sewage pump, stainless steel explosion-proof submersible pump, small submersible pump, QY type submersible pump, automatic mixing sewage pump,
