Self-priming pumps are divided into the following categories according to the effect:
1. Gas-liquid inclusion type (including internal mixing and external mixing);
2. Water ring wheel type;
3. Jet type (including liquid jet and gas jet).
The task process of the gas-liquid mixed self-priming pump: Because of the extraordinary structure of the self-priming pump body, after the pump stops, there is a certain amount of water in the pump body. After the pump is started again, the air in the suction line is sucked due to the impeller torsion effect. The water is abundant and mixed, and is discharged into the gas and water. The gas from the upper part of the chamber overflows. The lower part of the water returns to the impeller, and the residual air from the new and suction lines is mixed until the gas in the pump and the suction pipe is exhausted. Complete self-priming and pumping normally. The water ring wheel self-priming pump combines the water ring wheel and the pump impeller in a casing, and discharges the gas by means of the water ring wheel to complete self-priming. When the self-priming pump is in normal operation, the passage of the water ring wheel and the pump impeller can be intercepted by the valve, and the liquid in the falling ring wheel can be lost.
Self-priming pump features:
1. The pump body is made of stainless steel, and all over-current metal parts are stainless steel (1Cr18Ni9Ti) s304 or S316L.
2. The viscosity of the medium can be up to 5000 centipoise. 3. It can be supplied with gas-liquid, foam liquid without gas resistance. 4. It can be supplied with suspended soft and hard particle media.
5. Small size, large flow rate - generally speaking, compared with competitive pumps, the volume is the smallest under uniform flow. Easy to install and move.
6. Fully self-priming when squatting - no additional installation required, no need to priming before starting. Suction can reach up to five meters.
7. The softening of the rotor does not damage the medium that is sensitive to shearing, such as paper pulp.
8. When the flexible rotor is running, there is no metal contact and no spark occurs. After the explosion-proof motor is equipped, it is especially suitable for the transportation of alcohol, gasoline, acetone and other solvents.
9. Beautiful appearance, durable and easy to maintain
