QZB series submersible axial flow pump

The QZB series submersible axial flow pump and QHB series submersible mixed flow pump are new energy-saving electromechanical integrated products that replace vertical long axis axial flow pumps. They are suitable for transporting clean water or liquids with physical and chemical properties similar to water up to 40 ℃, and allow for mild impurities. It can be widely used in farmland irrigation and drainage, industrial circulating water transmission, urban water supply and drainage, environmental protection projects, mudflat aquaculture or other water conservancy projects. The QZ submersible axial flow pump has become an ideal replacement product for traditional axial flow pumps due to its simple structure, low hydraulic cost, high efficiency, and easy installation.

Main features:

Due to submersible operation, geotechnical and building structural engineering can be greatly simplified, and longer shaft pumps can save 30-40% of engineering costs.

Low operating costs, compared with long axis axial flow pumps, the overall unit efficiency is high, and can save 20% electricity.

The water pump is coaxial with the motor, and the motor is placed above the pump. It is a dry fully enclosed submersible three-phase asynchronous motor, which can operate underwater for a long time.

Due to the integration of the motor and water pump, the trouble of aligning the motor and water pump axis is avoided, and on-site installation is fast and convenient.

All units operate underwater with low noise and smooth operation.

The unit can be started without watering, and the operation is simple and convenient.

Adopting dual mechanical seals and auxiliary shaft seals, and equipped with motor insulation over limit protection device and sealed oil chamber water inlet alarm device to ensure the safe operation of the unit.

Equipped with a control cabinet to achieve voltage reduction starting, overload protection, phase loss protection, and submersible motor leakage protection for the motor.

Equipped with a water level alarm mechanism to ensure that the pump operates under reasonable conditions and can be operated without human intervention.

It can completely solve the flood control problem of building pumping stations in areas along rivers and lakes with large water level differences.

The movable installation method provides optimal conditions for establishing a mobile pump station in drainage and irrigation projects.

Choosing this pump for the long axis axial flow pump station can achieve underground pumping and save all ground buildings.

Eliminating the long shaft transmission components of traditional axial flow pumps, reducing volume, weight, and facilitating transportation.

Equipped with a wiring conversion device, the cable is easy to replace due to wear and tear.
