What is the working principle of the explosion-proof self-priming pump?

The explosion-proof self-priming pump is a vacuum pump that sucks and squeezes liquid, and has some unique characteristics. Since its invention more than 60 years ago, it has been used more and more widely in various industrial and mining applications.

Its working principle is:

1 There is an eccentric cam in the pump chamber. As the flexible vane leaves the eccentric mass, the volume between the vanes increases and a vacuum is created, which causes the liquid to be drawn into the pump chamber inlet without interruption.

2 When the flexible blade rotates, the liquid is carried into the discharge portion by the pump chamber suction portion.

3 When the flexible blade comes into contact with the eccentric cam again, bending occurs, and accompanied by a pressing action, the liquid is discharged out of the pump chamber without interruption or pulsation, thereby completing the entire process of suction and discharge.

Its core technology is the flexible elastomer technology of the impeller.

As the core technology of the flexible pump, the impeller of the pump should have good elasticity, small deformation, and can withstand long-term high frequency flexing without breaking or tearing. “Ten years of grinding a sword”, the superior impeller elastomer technology determines the superior performance and durability of the pump. There are two kinds of materials for the impeller - sanitary EPDM; the impeller is mainly used in the fields of vegetable oil, mineral oil, oily medium and high sanitary requirements; the ethylene-propylene wheel is mainly used for weak inorganic acids, organic acids and alkalis. A wide range of media such as salt, alcohol, ketone, and sewage.

The explosion-proof self-priming pump mainly consists of the following 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 transport medium can reach 5000 centipoise

3. It can transport gas-containing liquid, foam liquid without gas resistance

4. It can transport medium containing suspended soft and hard particles.

5. Small size, large flow rate - generally speaking, the volume is the smallest under the same flow rate compared with the competitive pump type. Easy to install and move.

6. Instantly self-priming - no additional equipment required, no need to priming before starting. Suction can reach up to five meters. 7. The gentle action of the rotor does not damage media that are sensitive to shearing, such as papermaking dispersants.

7. The flexible rotor has no metal contact during operation, and the torque limiter does not generate sparks. It is especially suitable for the transportation of solvents such as alcohol, gasoline and acetone after the explosion-proof motor.

8. Beautiful appearance, durable and easy to maintain
