Multifunctional energy-saving buffer supercharger

Abstract

The invention relates to a multifunctional energy-saving buffer supercharger. In order to solve the problem of poor flow performance of existing equipment, it includes a water injection pipe head for connecting a water injection pipe and a water supply pipe head for connecting a high-pressure water supply pipe. The water supply pipe head is connected with a casing or a section of variable diameter pipe with a large front and a small rear. The variable diameter pipe or casing has a built-in booster spring. The front end of the booster spring is equipped with a booster stopper with a water hole in the center. The rear end of the booster spring is equipped with a valve plate matched with the small-diameter end of the variable-diameter pipe body or the rear end of the sleeve pipe or the head end of the water supply pipe. The inner circumference of the small-diameter end of the variable-diameter pipe body or the head end of the water supply pipe is formed or equipped with a ring seat that is sealingly matched with the valve plate. With simple structure and easy operation, it can increase the water injection pressure, reduce equipment loss, reduce power consumption, stop the pump water will not flow back, and the water injection changes from low-pressure coarse flow to high-pressure fine flow, which can easily enter the coal seam gap and infiltrate the coal body Even, it can also achieve good liquid injection effect for dense coal seams.

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...
