Product description

1. Introduction to ZQB and HQB submersible axial flow pumps and mixed flow pumps

The ZQB submersible axial flow pump and the HQB submersible mixed flow pump are the updated products of the traditional pump-motor unit. The integrated machine and pump can be submerged in the water for a long time and have a series of outstanding advantages.

2. Advantages of ZQB and HQB submersible axial flow pumps and mixed flow pumps

1. As the pump runs submerged in the water, it greatly simplifies the geotechnical and building structure engineering of the pumping station, reduces the installation area, and can save 30%-40% of the total project cost.

2. Since the water pump and the motor are integrated, there is no need to carry out the shaft-to-center assembly process on site, and the installation is convenient and fast.

3. Low noise, no high temperature in the pumping station, to improve working conditions, and an all-underground pumping station can also be built as required to maintain the ground environment.

4. Convenient operation, no need to lubricate the rubber bearing of the water pump before starting up, and it can be remotely controlled and automatically controlled by time.

5. It can be used for irrigation and drainage of farmland, industrial and mining docks, urban construction, and water supply and drainage of power stations along the river where the water level fluctuates greatly.

6. The ZQB submersible axial flow pump is suitable for low head and large flow occasions. The HQB submersible mixed flow pump has high efficiency and good gas turbidity. It is suitable for occasions with large water level fluctuations and high head requirements.

7. The conveying medium is water or other liquids with physical and chemical properties similar to water. The temperature of the conveyed liquid is higher than 40°C.

3. The scope of application of ZQB and HQB submersible axial flow pumps and mixed flow pumps

ZQB, HQB submersible axial flow pumps and mixed flow pumps are widely used in farmland irrigation and drainage, industrial and mining docks, urban construction, power station water supply and drainage and water conservancy projects.

4. ZQB, HQB type submersible axial flow pump, mixed flow pump operating conditions

1. It is suitable for conveying clean water or other liquids with physical and chemical properties similar to water. The higher temperature of the conveyed medium is: 40℃.

2. PH value of the conveyed medium: 5-9.

3. Larger diving depth: 10m.

4. The interval between two starts is not less than 10 minutes.

5. Technical requirements for ZQB and HQB submersible axial flow pumps and mixed flow pumps

1. The submersible axial flow pump is used to pump rainwater with a small amount of floating objects in the urban rainwater pumping station, and it can work normally.

2. The inlet chamber of the submersible axial flow pump is equipped with a conical inlet and anti-vortex facilities to ensure an ideal inlet flow pattern at the suction inlet.

3. The submersible axial flow pump can work normally within the specified range and has stable head flow characteristics. When the pump runs at any point on its characteristic curve, the motor power is not overloaded.

4. All pressure-bearing parts of the submersible axial flow pump are subjected to air pressure test, and the test pressure is 1.5 times of the design pressure, but not less than 0.4Mpa, which lasts for 5 minutes without leakage.

5. After the submersible axial flow pump is sealed and assembled, the 0.4MPa air pressure test is carried out, and there is no leakage for 5 minutes.

6. The submersible axial flow pump is sprayed with anticorrosive paint, and its surface is bright, without fouling, bumps, cracks, etc., and the surface of the parts is sprayed with epoxy resin anticorrosive paint after derusting and degreasing

7. The impeller of the submersible axial flow pump adopts a semi-adjustable structure. The impeller blades and the spherical chamber are perfectly matched, and the gap is uniform. The impeller undergoes a static balance test before assembly. The imbalance is within its allowable range, and the balance accuracy is G6.3.
