2, the self-priming height can not exceed the specified value of 5-6.5 meters, suction tube length ≤10 meters.

Type meaning

Working principle of structure

Both ZXL direct connected self-priming pump and CYZ-A direct connected self-priming centrifugal pump adopt the pump body structure of axial liquid return. The pump body is composed of suction chamber, liquid storage chamber, vortex chamber, liquid return hole, gas-liquid separation chamber, etc. After the pump starts normally, the impeller inhales the liquid stored in the suction chamber and the air in the suction pipe together, and can be completely mixed in the impeller. Under the action of centrifugal force, the liquid carries the gas to the outdoor edge of the vortex. At the outer edge of the impeller, a white foam band with a certain thickness and a high-speed spinning ring are formed. The gas-liquid mixture enters the gas-liquid separation chamber through the diffusion tube. At this time, due to the sudden decrease in flow rate, the lighter gas is separated from the mixture, and the gas continues to rise through the pump body. The degassed liquid returns to the liquid storage chamber and enters the impeller again through the reflux hole. It is mixed with the gas inhaled from the suction pipe inside the impeller again. Under the action of the high-speed rotating impeller, the degassed liquid flows to the outer edge of the impeller...... . As this process goes on again and again, the air in the suction line is continuously reduced until the gas is sucked out, the self-priming process is completed, and the pump is put into normal operation. Because of this unique exhaust capability, both pumps can transport liquids containing gases without the need to install a bottom valve. CYZ-A direct-connected self-priming centrifugal oil pump has good sweeping function when used on oil tankers.

Structure description:

1, motor: directly connected with the pump to transmit power, the use of motor. CYZ-A pumps use explosion-proof motors.

2. Pump shaft: coaxial with motor. The shaft is extended for the motor to ensure the concentricity of the shaft, so that the pump runs smoothly, no noise and vibration phenomenon, and adopts chrome plating treatment to enhance the service life.

3. Water retaining ring: prevent water from entering the motor due to sealing water leakage.

4. mechanical seal: made of stainless steel, tungsten carbide, fluorine rubber and other materials. Balanced high temperature and high pressure mechanical seal, long operating life, no leakage, no wear to the shaft, no scale, so that the working environment is clean.

5. Pump cover: Connect pump body and motor

6. pump body: the extrusion chamber and suction chamber and the gas-liquid separation chamber are designed with excellent hydraulic model, which is beautiful and efficient, and the installation foot is convenient for installation and stable operation.

7. impeller: The use of higher hydraulic model design, with efficiency, good reliability and other characteristics.

8. sealing ring: pump impeller and pump body joints play a sealing role.

9. Bottom cover plate: When there is dirt deposition in the pump body, the bottom cover plate can be opened to remove dirt.

10. drain water hydrant: when the pump is not used for a long time, you can open the drain water hydrant to drain the storage liquid.

11. chassis: connected to the whole pump for easy installation, you can also install vibration isolators.

12. Outlet nozzle: Connect the outlet pipe

13. water valve: when the pump cavity storage is insufficient, the valve can be opened to add water.

14. the upper return valve plate: when the pump stops working, it can prevent the water in the pipeline from returning

15. Interface takeover: Connect the inlet pipe.
