Problems solved by technology

[0002] The existing water pump provides the power source through the motor, and the motor drives the water-pressing mechanism inside the pump. The water-pressing mechanism quickly and briefly pushes the water in the pump to move forward to realize the pumping of the pump. For high-lift pumping, this method consumes power Large, high cost, and not environmentally friendly, and the water potential difference between the upper water source and the lower water of the existing large rivers is large, and the water is not effectively used when it is not pumped

Abstract

The invention discloses a large piston fast-reset device of a high pressure water suction pump. The large piston fast-reset device comprises a large piston. The right side of the large piston is provided with a reset spring. One end of the reset spring is fixedly connected with the end surface, close to the outer edge, of the right side of the large piston and connected with a supporting rod in a sleeving mode. The other end of the reset spring is connected with a fixing plate and can expand and contract along the supporting rod. The left end of the supporting rod is fixedly connected with the large piston. The right end of the supporting rod is connected with a reset piston. The reset piston is placed in a reset piston cavity with an opening at the right end. The reset piston cavity is fixedly connected with a cavity body. According to the large piston fast-reset device of the high pressure water suction pump, through the reset spring, the large piston can be fast reset, the reset piston is placed in the reset piston cavity, resetting and buffering functions can be achieved, so that a middle reset compressing spring firstly acts on an inner decompression valve and a decompression valve, so that the inner decompression valve and the decompression valve are opened, the fact that the large piston is opened in advance for conducting decompression is achieved, and acting force of the left end of the large piston is reduced, so that the reset sensitivity is further improved.

Description

technical field [0001] The invention belongs to the technical field of pressurized water pumps, and relates to a quick reset device for a large piston of a high-pressure water pump. Background technique [0002] The existing water pump provides the power source through the motor, and the motor drives the water-pressing mechanism inside the pump. The water-pressing mechanism quickly and briefly pushes the water in the pump to move forward to realize the pumping of the pump. For high-lift pumping, this method consumes power Large, high cost, and not environmentally friendly, and the water potential difference between the upper water source and the lower water of the existing large rivers and rivers is large, and it is not effectively used when the water is not pumped. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a quick reset device for a large piston of a high-pressure water pump, capable of pumping water with ...
