Multifunctional energy-saving buffering supercharger

Abstract

The invention relates to a multifunctional energy-saving buffering supercharger which solves the problem of poor water running performance of the existing device. The multifunctional energy-saving buffering supercharger comprises a water injection pipe connector for connecting a water injection pipe and a water supply pipe connector for connecting a high pressure water supply pipe. A casing pipe or a section of a reducing pipe body with front end large and rear end small is connected between the water injection pipe connector and the water supply pipe connector, a supercharging spring is arranged in the reducing pipe body or the casing pipe, a supercharging blocking sheet with a water through hole in the middle is assembled at the front end of the supercharging spring, and a valve block matched with the small-diameter end of the reducing pipe body, or the rear end of the casing pipe or the end of the water supply pipe contactor is assembled at the rear end of the supercharging spring. An annular seat in sealing match with the valve block is manufactured or arranged on the inner periphery of the small-diameter end of the reducing pipe body or the end of the water supply pipe contactor. The multifunctional energy-saving buffering supercharger has the advantages that the structure is simple, the operation is convenient, water injection pressure can be enlarged, wear of devices and power consumption are reduced, water cannot flow back when a pump stops, low-pressure thick flow of water injection is changed into high-pressure thin flow, water can easily enter gaps of coal seams to evenly wet coal, and good liquid injection effect can be achieved to the coal seams with compact structures.

Description

technical field [0001] The invention relates to coal seam water injection (liquid) technology in coal mines, in particular to a multifunctional energy-saving buffer supercharger. Background technique [0002] When working underground in coal mines, due to the large coal dust, many coal mines perform coal seam water injection to reduce coal dust and improve the working environment (or add other agents to the water to achieve purposes other than dust reduction). And when water is injected, because of the difference of coal seam, the required water injection pressure is also different, and the pressure of 30MPa in some coal mines also can't inject water. Moreover, the use of high voltage consumes electricity, wears out equipment, and the water injection is uneven, and it is easy to cause a burst. Contents of the invention [0003] The object of the present invention is to solve the above problems and provide a multifunctional energy-saving buffer supercharger with simple str...
