Abstract

The invention discloses a high-efficiency energy-saving self-priming centrifugal hydraulic system, and relates to the technical field of water pumps. The high-efficiency energy-saving self-priming centrifugal hydraulic system is characterized in that the high-efficiency energy-saving self-priming centrifugal hydraulic system comprises a pump body, the pump body is provided with a centrifugal impeller, a water inlet channel, a centrifugal cavity and a water outlet channel, the pump body is provided with an ejector, an energy storage bin, a communication channel and a self-adaptive regulating valve, the self-adaptive regulating valve comprises an outer shell and a self-adaptive floating ball body, the outer shell is provided with a streaming cavity, a water inlet and a water outlet, the streaming cavity comprises a guide section, the water inlet channel is provided with a narrow opening section, the energy storage bin is provided with a water supplementing inlet, the inner wall of the water inlet channel is provided with a stepped annular groove, the end of the centrifugal impeller is provided with a protrusion, the inner wall of the water outlet channel is provided with a backflow cavity, and the inner wall of the backflow cavity is provided with an elastic arc plate. By arranging the ejector and the self-adaptive regulating valve, so that the energy loss of the pump body is reduced, the energy utilization rate of the pump body is increased, and the pump body is more efficient and energy-saving; by arranging the narrow opening section, the self-priming capacity of the pump body is improved; and by arranging the elastic arc plate, the energy utilization rate of the pump body is further increased.

Description

technical field [0001] The invention relates to the technical field of water pumps, in particular to a high-efficiency energy-saving self-priming centrifugal hydraulic system. Background technique [0002] At present, the water pump is a machine that transports liquid or pressurizes the liquid. It transmits the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid, and is mainly used to transport the liquid. [0003] Suction centrifugal pump is a kind of water pump. Self-priming pump is a single-stage single-suction centrifugal pump that produces self-priming effect by the special structure of the pump itself. Compared with ordinary centrifugal pumps, there are significant differences in the structure of the pump body: one is The inlet position of the pump is improved, and sometimes a suction valve is installed; the second is to set a water-air separation chamber on the water outlet side. [0004] The existing centr...

AI Technical Summary

Problems solved by technology

[0004] The existing centrifugal self-priming pump generally adopts a filled self-priming structure, and the self-priming pump is usually replenished at the water inlet, while the water circulation in the internal water-air separation chamber and the centrifugal impeller cavity is still in the process of pumping water. In progress, self-priming is still in progress, resulting in high energy loss and the defect of low energy utilization rate, which cannot meet the requirements of large flow and high suction lift
