Do You Know The Characteristics Of Submersible Axial Flow Pump?

Jun 01, 2022

Submersible axial flow pump is a submersible pump based on the working principle of axial flow. It is characterized by large flow and low head. The flow can reach tens of thousands of cubic meters per hour and the head is no more than 20 meters. The motors are multi pole motors with low speed. Most of the installation methods are shaft type and sled type, which are commonly used in pump stations and are called flood drainage sharp tools!

The motor of the submersible axial flow pump is coaxial with the water pump, and the motor is a dry fully enclosed submersible three-phase asynchronous motor.

The submersible axial flow pump adopts double and triple mechanical seal and auxiliary seal structure, with class F insulation and protection grade of IP68. The motor is equipped with seal leakage, winding and bearing temperature rise, junction box and oil chamber water inlet detection devices. All detection signals are fed back to a special protector for submersible electric pump on the electric control cabinet for monitoring, and audible and visual alarm in case of failure. To ensure the normal operation of the positive electric pump.

Due to the integration of submersible axial flow pump motor and water pump, the installation height is reduced, and the weight of the unit is 40% lower than that of the traditional pump. There is no need to carry out labor-consuming and time-consuming complex axis alignment process on site. The on-site installation is very convenient, and a complete set of electric pump can be installed in about 2-3 hours.

As the submersible axial-flow pump runs in the water, the water flows through the surface of the motor, the motor is cooled well, and there is no high temperature and noise in the pump station. An underground pump station can be built to maintain the ground style and save 30% - 40% of the total civil construction cost. Easy to operate, easy to realize remote control and automatic control.

The medium conveyed by the submersible axial-flow pump is raw water or light sewage, the temperature of the conveyed liquid is 50 ℃, the pH value is 4-10, the volume ratio of the conveyed medium is less than 2%, and the density of the medium is less than 1.2 * 1000kg / m3. This product is very suitable for rivers and lakes with large water level fluctuation, and is the best way to solve the problem of flood prevention by motors.

There are many ways to install the product, which can be divided into: suspension installation, floor installation, cable-stayed installation, open installation, etc.

The use of this type of submersible electric pump is a way to solve the problem of building pump stations along rivers and lakes where the water level fluctuates greatly, solve the problem of complete motor flood control, and omit the long shaft and intermediate bearing between machines and pumps, so as to make the operation of the unit more reliable.

Submersible axial flow pump: the motor driving the water pump is a dry fully enclosed submersible three-phase asynchronous motor, which can be immersed in water for a long time, and has a series of unparalleled advantages of traditional units.

Since the motor and the water pump are integrated, there is no need to end the labor-consuming and time-consuming assembly process of the axis alignment of the motor, transmission mechanism and water pump on the assembly site. The on-site assembly is convenient and fast.
