product details:

First, product introduction

    The QZB axial flow submersible pump and the QHB mixed flow water pump are the replacement products of the traditional water pump motor group. The motor for driving the water pump is a dry type fully closed submersible three-phase asynchronous motor, which can invade the water for a long time. A series of unparalleled advantages of traditional units.

    Since the motor and the water pump are integrated, the on-site installation is convenient and fast, and the installation time can be saved by 95% compared with the conventional unit.

    Because the motor sneaked into the water, the motor has good cooling conditions, no high temperature in the pumping station, low noise, and can be built into an underground pumping station to maintain the ground environment, greatly simplify the geotechnical and building structure of the pumping station, reduce the installation area, and save the project cost. -40%

    The submersible motor adopts double and triple mechanical seals and auxiliary sealing structure. The F-class is resistant to temperature 155C insulation and the protection grade is IP68. And set seal leakage, winding and bearing temperature rise detection device in the motor

    The detection signal is concentratedly fed back to the monitoring room of the electric control cabinet, which is convenient to operate and easy to realize automatic control and remote control.

Second, the main use of the environment

    QZB/QHB two types of submersible pumps can be widely used in working condition docks, urban water supply and drainage, farmland irrigation, power supply and drainage. QZB axial flow submersible pump is suitable for low lift and large flow occasions. QHB mixed flow submersible pump has high efficiency and good cavitation performance. It is suitable for occasions with large water level changes and relatively high lift. The above-mentioned product conveying medium is raw water or mild sewage, the highest conveying liquid problem is 50C degree, the conveying medium has a PH value of 4-10, the transported medium has a volume ratio of less than 2%, and the medium sealing is less than 1.2*10 3KG/ M3. The use of this product is the most thorough way to solve the flood control problem of building stations along rivers and lakes with large fluctuations in water level.

Third, the structure description

    The structure of the submersible pump is shown in the figure below. The submersible motor of the submersible pump is placed above the pump. The submersible motor has a dry structure, F-class insulation, reliable mechanical seal and auxiliary seal, and has leakage and internal winding, bearing temperature rise protection device and supporting control cabinet. The operation is safe and reliable, the water quality and environment are widely applicable, the blades are adjustable, and the working conditions are large.

    Seen from the direction of the water inlet, the impeller rotates counterclockwise.

    When the click power is below 315KW, the voltage is 380V or 600V. When the motor power is above 315KW, the voltage is 6KV or 10KV.
