Definitions

  • the invention relates to a high-pressure air pump.
  • the working principle of the existing high-pressure air pumps is mostly piston or screw type. Due to the repeated movement of the piston or screw, the wear rate of the piston or screw is high and the life is low. As a result, the existing high-pressure air pumps are prone to wear and low life. Since the recent improvements in high-pressure air pumps are all revolving around pistons, the problems of high wear and low life of high-pressure air pumps cannot be fundamentally solved.
  • An object of the present invention is to provide a hydraulic high-pressure air pump that does not require a piston, is resistant to wear and has a long life.
  • a hydraulic high-pressure air pump is composed of a steel cylinder, a hydraulic pump, and the like. ; At least one of the two cylinders has an air inlet and outlet, and at least one of the cylinders has a liquid inlet.
  • Figure 1 is a schematic diagram of the structure of the present invention
  • the hydraulic high-pressure air pump of the present invention has two steel cylinders, namely, a steel cylinder 1 and a steel cylinder 2.
  • the two steel cylinders are connected to the hydraulic distribution valve 5 through a pipeline 3, and the hydraulic distribution valve 5 is connected to the hydraulic pump 6.
  • At least one of the two steel cylinders of the present invention has an air inlet and outlet, and at least one of the steel cylinders has a liquid inlet.
  • One cylinder can only have air inlets and outlets, one cylinder can only have liquid inlets, or both cylinders can have both air inlets and outlets.
  • the two steel cylinders 1 and 2 have air inlets and outlets 7 and 8, respectively, and the steel cylinder 1 also has a liquid inlet 9.
  • Liquid level sensors 10 and 11 are provided at the air inlets and outlets of the cylinders 1 and 2. The control signals output by the liquid level sensors 10 and 11 control the operation of the hydraulic pressure distribution valve 2.
  • the gas inlets and outlets of the cylinders 1 and 2 are also provided with gas valves 12, 13, and 12 and 13, which are connected to the gas storage tank 15 through a pipeline and a one-way valve 14.
  • the pressure of the hydraulic high-pressure air pump can be set manually as required.
  • the present invention can provide a plurality of steel cylinders.
  • the hydraulic high-pressure air pump of the present invention utilizes the principle that liquid cannot be compressed and air can be compressed.
  • the hydraulic pump compresses the air in the cylinder to form a high-pressure gas without the need for a piston, so that the hydraulic high-pressure gas pump of the present invention is resistant to wear and has a long service life.
  • the hydraulic pump can reach a large pressure, so that The invention can output higher pressure air.
  • the hydraulic high pressure air pump has the advantages of small size, low noise, small wear, no air leakage, large gas production, etc., and can be widely used in the fields of industry, agriculture, power stations, navigation and the like.

Abstract

L'invention concerne une pompe de compression hydraulique de gaz comprenant une pompe hydraulique et deux cylindres en acier qui sont reliés à la pompe hydraulique par des conduits et dont au moins un présente une entrée et une sortie d'air et une entrée de liquide. Selon le principe de la compression sous vide, l'utilisation de cette pompe hydraulique permet que l'air dans les cylindres en acier soit comprimé hydrauliquement afin d'obtenir un gaz haute pression sans recourir à un piston. Cette pompe hydraulique présente encore l'avantage de résister à l'usure et d'avoir une longue durée de vie.
