Mix/Axial Flow Pump
QZ submersible axial flow pump, the motor driving the pump is dry type fully enclosed submersible three-phase asynchronous motor.
The pump and motor shaft are integrated.Can be long - term underwater operation, with a series of traditional units incomparable advantages.
Because the pump and motor together ,Can Diving into the water at the same time, there is no need to carry out power consumption and time-consuming assembly process at the installation site, which is convenient and fast for on-site installation.
The electric pump running under water can greatly simplify the civil structure of the pump station, reduce the installation area and save 30%-40% of the total cost of the civil engineering. Electric pump submerged operation, low noise, good motor cooling effect, no high temperature in the pump station, no noise interference, improve the working environment of the pump station, at the same time, according to the requirements of the construction of underground pump station, maintain the surface environment.
Easy operation, flexible, can be opened and closed at any time unit, no need to lubricate the pump before starting the rubber bearing, easy to achieve remote control and automatic control. The unit is easy to assemble and disassemble and easy to maintain. It is the most thorough way to solve the problem of flood control of pumping stations along the big river and lake area with water level tension. The long shaft between pump and motor is omitted, and the reliability of operation safety is improved.
If the variable frequency control is used, the input power of the motor can be automatically controlled to adapt to the change of water level, so as to save energy and reduce consumption..
It can also realize remote control, establish the central control room, and truly realize the modernization of pump station management....
