No. 192, Bianzhong East Road, Chengqiao Street, Liuhe District, Nanjing City, Jiangsu Province, China

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

The ZQB submersible axial flow pump and HQB submersible mixed flow pump are upgraded products of the traditional water pump electric motor unit. The integrated machine pump can operate for a long time underwater and has a series of outstanding advantages.

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

1. Due to the submersible operation of the pump, the geotechnical and structural engineering of the pump station has been greatly simplified, reducing the installation area and saving 30% -40% of the total project price.

2. Due to the integration of the water pump and motor, there is no need to perform shaft to center assembly on site, making installation convenient and fast.

3. Low noise, no high temperature inside the pump station, improving working conditions, and can also be built as required to maintain the environmental style of the ground.

4. Easy to operate, no need to lubricate the rubber bearings of the water pump before starting up, and can be remotely and automatically controlled over time.

5. It can solve the problem of large water level fluctuations along the river, providing irrigation and drainage for farmland, industrial and mining docks, urban construction, and power station water supply and drainage.

6. The ZQB submersible axial flow pump is suitable for low head and high flow situations, while the HQB submersible mixed flow pump has high efficiency, good air turbidity performance, and is suitable for situations 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, and the temperature of the conveyed liquid is relatively high at 40 ℃.

3、 Scope of application for ZQB and HQB submersible axial flow pumps and mixed flow pumps

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

4、 Usage conditions for ZQB and HQB submersible axial flow pumps and mixed flow pumps

1. Suitable for transporting clean water or other liquids with physical and chemical properties similar to water. The medium being transported has a higher temperature of 40 ℃.

2. The pH value of the conveyed medium is 5-9.

3. Larger diving depth: 10m.

4. The interval between each two starts shall not be less than 10 minutes.

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

1. Submersible axial flow pump is used to pump rainwater containing a small amount of floating debris in urban rainwater pumping stations, 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 state at the suction port.

3. Submersible axial flow pumps can operate normally within the specified range and have stable head flow characteristics. When the pump operates at any point on its characteristic curve, the motor power does not overload.

4. All pressure bearing parts of the submersible axial flow pump shall undergo a pressure test, with a test pressure of 1.5 times its design pressure but not less than 0.4 Mpa, for a period of 5 minutes without any leakage.

5. After sealing assembly, the submersible axial flow pump underwent a 0.4MPa air pressure test for 5 minutes without any leakage.

6. The submersible axial flow pump is sprayed with anti-corrosion paint, which has a bright surface and no stains, bumps, cracks or other phenomena. After rust removal and oil removal, the surface of the components is sprayed with epoxy resin anti-corrosion paint

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