Improved self-suction centrifugal pump

Abstract

The invention relates to the technical field of self-suction centrifugal pumps, in particular to an improved self-suction centrifugal pump. The improved self-suction centrifugal pump comprises a centrifugal pump body, an air compressor, a jet assembly and a check valve; the top of the jet assembly is provided with a suction chamber, and a nozzle is arranged on the suction chamber and connected with an air outlet of the air compressor through a high-pressure air pipe; the jet assembly is arranged on a water inlet of the centrifugal pump body and communicates with the water inlet; a floating ball assembly is arranged below the suction chamber; and a bottom plate of the suction chamber is provided with an air outlet. According to the improved self-suction centrifugal pump provided by the invention, the air compressor, the jet assembly and the check valve are combined and used, centrifugal pump self suction is achieved, the jet assembly is provided with the floating ball assembly, the water level of the water inlet of the centrifugal pump body ascends during self suction, thus, a floating ball moves upwards, a sealing head is attached to the air outlet of the suction chamber through lever force transmission, accordingly, air exhaust is automatically stopped without manual operation, and using is convenient and quick.

Description

technical field [0001] The invention relates to the technical field of self-priming centrifugal pumps, in particular to an improved self-priming centrifugal pump. Background technique [0002] A pump is a machine that transports or pressurizes a fluid. It transfers the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. Before the pump works, the pump body and the water inlet pipe must be manually filled with water. When the impeller rotates rapidly, the blades make the water rotate quickly, and the rotating water flies away from the impeller under the action of centrifugal force, and the water in the pump is After being thrown, the central part of the impeller forms a vacuum area. The water from the water source is pressed into the water inlet pipe through the pipe network under the action of atmospheric pressure (or water pressure). The circulation is endless like this, just can realize continuous pumping. M...

Problems solved by technology

However, when the invention is in use, it still needs to manually adjust the clutch according to the self-priming situation to realize the opening and closing of the corresponding valve, which requires more human operation, and there is still room for improvement.
