Centrifugal self-priming pump

First, what is the centrifugal self-priming pump?

Centrifugal self-priming pump is a motor driven impeller high-speed operation. Due to the action of the blade, the liquid obtains energy and flows along the surface of the rotating liquid ring in helical shape. Under the action of centrifugal force, it is thrown to the space outside the direction of centrifugal force (mainly the atmosphere), thus converting kinetic energy into static pressure energy for storage. When fresh blood is needed, a special self-filling pump can be completed by opening the outlet valve and the gate valve of the suction line

The device.

Working principle of centrifugal self-priming pump:

1. The belt disk on the motor drive shaft is connected with the drive bearing through the coupling

Connected, and then connected to the driving gear in the reduction box through the elastic pin

Go up.

2. The driven gear is installed on the outside of the shell, and is closed with the active and passive teeth

Rotation to transfer dynamic torque and torque output to the cochlea or planetary frame

And other parts.

3. The rotor rotates around its center line and fricts with the inner wall of the stator to produce vacuum degree difference, forming negative pressure, that is, vacuum zone at the suction port.

4, to absorb the air and water in the container into the suction chamber for gas-liquid mixing.

5, and then discharge along the exhaust pipe to the spit pipe road. At this time, the gas mixture is filtered through the filter screen and then sent to the storage tank for reuse. (If used for sewage irrigation, sterilization system should be added)

Three, the characteristics of centrifugal self-absorbent motor:

(1) Simple and reasonable structure, small size, light weight, smooth operation

Reliability and other advantages.

2) It has the characteristics of high efficiency and wide range of performance.

(3) Strong overload capacity.

4) Speed adjustment is convenient.

(5) stepless speed regulation, can meet different flow requirements.

(6) Low noise.
