Vortex pump capable of reducing noise and meanwhile reinforcing self suction and having superhydrophobic gas-liquid separation

Abstract

The invention discloses a vortex pump capable of reducing noise and meanwhile reinforcing self suction and having superhydrophobic gas-liquid separation. The pump comprises an impeller, a pumping chamber, a gas and liquid separation chamber, a vortex pump outlet, a pre-water-injection opening, and a water suction chamber. A superhydrophobic porous semipermeable wall is mounted in the gas and liquid separation chamber, and additionally isolates a gas collection chamber from the gas and liquid separation chamber, the gas collection chamber communicates with the vortex pump outlet through an exhaust hole, gas in gas and liquid mixed fluid in the gas and liquid separation chamber enters the gas collection chamber through the superhydrophobic porous semipermeable wall and is exhausted through the exhaust hole, and the liquid cannot pass through the superhydrophobic porous semipermeable wall to be wound back to the water suction chamber again. The superhydrophobic porous semipermeable wall with the outer surface coated with a superhydrophobic material isolates the gas collection chamber special for exhaust from the gas and liquid separation chamber, the noise generated by cavitation is reduced, and meanwhile, the self suction and exhaust capacity of the vortex pump can be improved.

Description

technical field [0001] The invention relates to the technical field of water pumps, in particular to a vortex pump with superhydrophobic gas-liquid separation capable of reducing noise and enhancing self-priming. Background technique [0002] The vortex pump is a kind of vane pump. In terms of principle and structure, it is different from the centrifugal and axial flow pumps. Because it sucks and discharges the liquid by the effect of the vortex motion of the liquid when the impeller rotates, so called a vortex pump. The main components of the vortex pump are impeller, pump body, pump cover and the annular flow channel formed by them. The impeller of the vortex pump is different from the impeller of the centrifugal pump. It has a disk with radial blades on its outer wheel. The liquid enters the flow channel from the suction pipe, and obtains energy through the rotating impeller, and is transported to the discharge pipe to complete the working process of the pump.

Problems solved by technology

Furthermore, the self-priming capacity of the vortex pump is worse than that of the jet pump, whether it is the self-priming range or the stability of the self-priming capacity, and the anti-interference ability. In particular, the vortex pump has high requirements for the assembly process, and a considerable To a certain extent, it is necessary to ensure its self-priming ability. If the assembly gap between the impeller and the tongue is too large, the exhaust self-priming ability will be significantly reduced, and if the assembly gap is too small, the impeller will be stuck and the vortex pump will not work normally.
