A two-stage pressurized and noise-reducing water hammer pump

Abstract

A two-grade pressurization and noise-lowering type hydraulic ram pump comprising a first-grade pressurizing pump body assembly and a second-grade pressurizing pump body assembly. The first-grade pressurizing pump body assembly and the second-grade pressurizing pump body assembly each comprise a tubing pump chamber, an elbow, a noise-lowering water draining valve, a check valve, a pressure accumulation buffering air tank, a high-pressure water input pipe, a one-way valve and a high-pressure water output pipe. Each tubing pump chamber is horizontally arranged. One end of the tubing pump chamberof the first-grade pressurizing pump body assembly communicates with a power water pipe through the corresponding check valve, one end of the tubing pump chamber of the second-grade pressurizing pumpbody assembly communicates with the high-pressure water output pipe of the first-grade pressurizing pump body assembly. The other end of each tubing pump chamber communicates with the corresponding noise-lowering water draining valve through the corresponding elbow. Each high-pressure water input pipe is vertically arranged. The lower end of each high-pressure water input pipe communicates with the corresponding tubing pump chamber. The upper end of each high-pressure water input pipe is provided with the corresponding one-way valve. Each pressure accumulation buffering air tank is installed on the corresponding high-pressure water input pipe in sealed and sleeving manners. Each one-way valve is located in the corresponding pressure accumulation buffering air tank. Each high-pressure wateroutput pipe communicates with a tank body of the corresponding pressure accumulation buffering air tank. The high-pressure water output pipe of the second-grade pressurizing pump body assembly communicates with an operating water pipe.

Description

technical field [0001] The invention belongs to the technical field of water hammer pumps, in particular to a two-stage pressurized and noise-reducing water hammer pump. Background technique [0002] The water hammer pump is a kind of water lifting device that uses flowing water as the power to generate water hammer effect through mechanical action, and then converts low water head energy into high water head energy. At present, water hammer pumps are mainly used for water lifting and irrigation in remote areas, and do not need to consume additional energy such as electric energy. Promote the use of water hammer pumps. [0003] With the promotion and use of water hammer pumps, water hammer pumps as water lifting equipment have been endowed with more functions, such as being used more and more to generate high-pressure water and use high-pressure water for other production operations. However, the water hammer pump with the traditional structure is still limited in the high...

AI Technical Summary

Problems solved by technology

However, the water hammer pump with the traditional structure is still limited in the high-pressure water production capacity, especially the gap between the water outlet pressure and the actual demand is large, which is specifically reflected in the pressurization capacity of the water hammer pump. For some special operations, it is necessary to use When spraying at high pressure, the water hammer pump with traditional structure cannot meet the requirements

In addition, although the traditional structure of the water hammer pump will be accompanied by a lot of noise during operation, when it is used for water lifting and irrigation, it can be left unattended most of the time, so the impact of the noise factor on people is relatively small. But when the water hammer pump is used to generate high-pressure water and perform other production operations, the impact of noise factors on people will be multiplied at this time
