Explosion-proof self-priming centrifugal pump is based on the relevant technical information at home and abroad by the digestion, absorption, improved after the development of the latest products, the pump for the oil industry, land oil depot, tank car ideal product. Now to say explosion-proof centrifugal pump working principle and characteristics of what? Explosion-proof self-priming centrifugal pump First, the explosion-proof self-priming centrifugal pump works Explosion-proof self-priming centrifugal pumps preclude the use of axial back to the pump body structure. The pump body is composed of a suction chamber, a liquid storage chamber, a scroll chamber, a liquid return hole, a gas-liquid separation chamber and the like. After the pump is normally started, the impeller sucks the liquid stored in the suction chamber and the air in the suction pipe together, Within the fully mixed, under the action of centrifugal force, the liquid entrained gas flow to the outer edge of the scroll chamber, the outer edge of the impeller formed with a thickness of white foam belt and high-speed rotating liquid ring. Gas-liquid mixture through the diffuser into the gas-liquid separation chamber. At this point, due to a sudden drop in flow rate, the lighter gas is separated from the mixed gas and the gas continues to rise through the pump outlet. Degassed liquid back to the liquid storage chamber and re-enter the impeller from the return hole, and the impeller suction from the suction pipe gas re-mixing, high-speed rotating impeller and flow to the outer edge of the impeller. As the process goes on and off, the air in the suction line is continuously depleted until the gas is exhausted, completing the self-priming process, and the pump is put into normal operation. Because of its unique venting capability, the pump delivers gas-laden liquids without the need to install a foot valve and has good sweeping capabilities when used on tankers. Explosion-proof self-priming centrifugal pump features 1, self-priming pump with a simple structure, easy operation, stable operation, easy maintenance, high efficiency, long life, and has other pumps do not have the self-priming function and so on. No need to end of the valve in the pipeline, just to ensure that the pump body before storage can be cited quantitative oil. With "a drainage, lifelong self-suction" function, for tanker or marine pumps, can double as a stripping pump, stripping a good effect. 2, Self-priming pump is made of high-quality materials, sealed with carbide mechanical seal, durable, spit out the pipeline does not require the installation of safety valves, suction pipe does not need to install the end valve thus simplifying the piping system and improve Labor conditions.
