Portable completely-oil-free gas supercharger

Abstract

The invention relates to the technical field of gas compression treatment, and especially relates to a portable completely-oil-free gas supercharger. The portable completely-oil-free gas supercharger comprises a cylinder cover, a valve sheet, a valve plate, cylinder bodies and floating pistons, and is characterized in that two groups of the cylinder bodies are vertically arranged on a crankcase side by side, a crankshaft is arranged in the crankcase, two crank pins are oppositely arranged at an angle of 180 degrees, and crank pin bearings are arranged on the crank pins; and the surfaces of the outer rings of the crank pin bearings and the floating pistons are attached and follow up through the driving force of a motor, the gravity and the pressure difference of gas, and the two crank pin bearings correspond to the two floating pistons in a one-to-one mode. The portable completely-oil-free gas supercharger has the following advantages: 1) multi-stage compression for the gas can be realized, and connecting-rod-free structural design is adopted, so that the portable completely-oil-free gas supercharger is small in size, light in weight and compact in structure; 2) the space occupied by a movement mechanism is greatly reduced, so that the size of the crankcase is reduced; and 3) a split crankcase structure is adopted, so that the machine is convenient to install, detach and maintain. Compared with an integral crankcase structure, the portable completely-oil-free gas supercharger is simple to machine, capable of reducing the weight, convenient to maintain, and portable.

Description

technical field [0001] The invention relates to the technical field of gas compression treatment, in particular to a portable oil-free gas booster. Background technique [0002] The gas pressurization equipment is suitable for the working environment that needs to increase the gas pressure, and can increase the pressure of the gas to be compressed in the working system by 2 to 25 times. The output pressure can be adjusted to the working pressure range allowed by the working place by adjusting the additional pressure reducing valve. At present, the structure of the pneumatic booster pump is generally a reciprocating plunger pump. When working, the booster pump reciprocates rapidly. As the output pressure increases, the reciprocation of the pump slows down until it stops. At this time, the pressure of the pump is constant and the energy consumption is the lowest. Part stops moving. Generally, the driving gas pressure: 0.3~0.8MPa, the maximum output pressure: 80MPa, that is t...

AI Technical Summary

Problems solved by technology

[0004] The disadvantage of the gas-driven plunger booster is that it is bulky and is not suitable for small-scale gas booster applications, especially the pressurized filling of medical oxygen. The booster is required to be portable and oil-free. None of the pressurized devices can well meet the requirements of oil-free and portable
