Supply the working principle of submersible axial flow pump of Tianjin Deneng pump industry

  Working principle of submersible axial flow pump supplied to Tianjin Deneng pump industry working principle of submersible axial flow pump:
QZ series submersible axial flow pump is specially designed for occasions with large flow and low head
The service head of submersible axial flow pump is generally less than 10m
This product is the best alternative to the traditional axial flow pump
The motor and the water pump form a whole and run in the water
It has a series of advantages unmatched by the traditional unit

In agriculture, it is used for irrigation and drainage: in municipal administration, it is used for drainage of rainwater and mild sewage; Used for water supply, cooling water and raw water supply in industry; It is used in water conservancy for water transfer projects
It is suitable for transporting clean water or light sewage
The nominal outlet diameter of the pump is 350, 500, 600, 700, 800, 900, 1000, 1200, 1400, 1600, 1800mm, etc

Since the motor and the water pump are integrated, there is no need for labor-consuming, time-consuming and complex axis alignment assembly procedures on site, and the installation is very convenient and fast
Therefore, the stand-by pump can be stored in the warehouse without reserving the stand-by pump, so as to save the investment in the inlet pool of the pump station
Due to submerged operation, the pump station and building structure engineering can be greatly simplified, the installation area can be reduced, and 30-40% of the total cost of the pump station can be saved

The pump runs in water and the water flows around the motor, with low noise and good cooling conditions for the motor
It can be built as an underground pump station to maintain the environmental style of the ground
The use of submersible electric pump is the most thorough method to solve the problems of pump station construction and flood control in areas along rivers and lakes with large water level fluctuation
It eliminates the long shaft between pumps and improves the safety and reliability of operation

The impeller is converted by the most advanced hydraulic model at present, with excellent performance, stability and maturity
Select a small nd value, which has good cavitation resistance and ensures smooth operation
Two sets of independent mechanical seals separate the motor from the pump; It is installed up and down in series to provide multiple insurances and improve reliability
The oil chamber is lubricated with oil and cooled and sealed to isolate the motor from the transmitted medium
The volume left inside can slow down the rise of pressure in the oil chamber

At the moment of unit startup, the reaction torque of motor starting torque often makes the whole unit rotate in the opposite direction
The anti rotation device can solve this problem
The bearing adopts rolling bearing, which can bear all axial and radial loads and is completely separated from the medium delivered by the pump
The pump is coaxial with the motor, with compact structure, shaft extension as short as possible, deflection reduction in design, small vibration during movement and longer service life of seal and bearing

High performance squirrel cage induction motor, especially designed and manufactured for submersible pump, meets gb755 standard
The insulation grade is f, and the maximum working temperature can reach 135 ℃ Depending on the power, 380V, 660V, 3KV, 6kV, 10kV and other voltage levels can be adopted
For high-voltage motors, twice VPI insulation process can be adopted to ensure reliable insulation
The motor shell directly transfers the heat to the surrounding medium, and the heat is taken away by the surrounding water flow
The high-power and high-voltage motor adopts the patented technology of internal air duct heat dissipation, so that the temperature rise of three-phase winding is low and the temperature field is evenly distributed

Equipped with electric control lead to the submersible pump
The protection devices include overload, phase loss, leakage, overtemperature, humidity, immersion protection, etc
the installation form with closed inlet channel is adopted

Submersible axial flow pump is suitable for drainage and irrigation pump station Large flow Low lift The transmission water quality is raw water Or light sewage The temperature of conveying medium is below 50 ℃ The lift is less than 10 meters, and the operation is simple Easy to use Fit the system An underground pumping station can be built Keep the ground clean It is most suitable for the riverside where the water level fluctuates greatly Stations will be built in lake areas Is the most thorough solution to flood control
