QZ/QH series submersible axial (mixed) flow Pump
Submersible shaft (mixed flow) pump is a kind of pump product which integrates submersible motor and water pump and can be immersed in water for a long time. The hydraulic design of axial flow pump is based on the lift theory in aerodynamics. When the impeller rotates at high speed, the liquid medium in the pump will be subjected to the axial lift generated by the impeller, thus driving the water flow in the axial direction. The liquid medium in mixed-flow pump is subjected to centrifugal force and axial lift at the same time, and the water flow direction of the impeller outlet is oblique. The motor is usually a dry totally enclosed submersible three-phase asynchronous motor, and the surrounding fluid medium has a good cooling effect on the motor.
Suitable for conveying clean water, rainwater, river water, sewage and other liquid media similar to clean water. The temperature can reach 40℃ and the PH value is between 4 and 10.
Working conditions:

3. Double and multiple mechanical seals can reliably prevent water leakage and prolong the maintenance cycle of the pump.
4. When the electric pump is running, the axial force and radial force are respectively provided with independent bearings, which have reasonable structural design, sufficient lubrication, good heat dissipation and long service life.
5. The motor adopts F-class insulation, which is high temperature resistant and equipped with temperature protection alarm device; The motor protection grade IPX8 ensures the safety and reliability of operation.
6. The cable inlet seal adopts a special full seal design, and the cable adopts a multi-layer seal compression structure, and the cable seal reliability is guaranteed by fixing.
7. The electric pump is equipped with winding overheating and leakage protection monitoring, and optional bearing overheating, bearing vibration and humidity monitoring to protect the reliable operation of the electric pump.
8. It can automatically collect the parameters of overheating, leakage, bearing overheating, bearing vibration and humidity of the electric pump, transmit them through the Internet and connect them into a smart cloud platform. Through the calculation, analysis and judgment of the cloud platform, the intelligent alarm and early warning functions are realized.
9, automatic and intelligent remote monitoring, operation and maintenance management, low operating cost.
10. The pump dives into the water, with good cooling conditions, good running balance, stability, small vibration and low noise.
11. The vertical installation of the pump has the advantages of small floor space, small pump station scale, simple civil and architectural structure, greatly reduced investment, and 30% ~ 40% of the project cost of the pump station can be saved.
