Abstract

The invention relates to a liquid piston type gas compressor. The liquid piston type gas compressor comprises at least one cylinder block, a hydraulic cylinder block is arranged between the cylinder block and a crankcase, the hydraulic cylinder block and the cylinder block are correspondingly communicated, the hydraulic cylinder block is internally provided with a piston, the piston is matched with the inner wall of the hydraulic cylinder block in a sliding manner, the lower end of the piston is connected with a crankshaft through a connecting rod, the upper part of the piston is filled with working fluid, the piston pushes the working fluid to move up and down in a cylinder to compress air in the cylinder through a liquid plunger, and a metal heat sink is installed in the cylinder block to directly cool the compressed gas. The liquid plunger can play the role of sealing the piston of the original air compressor and transmitting power. The liquid plunger will completely submerge the heat absorber during the up and down movement, and play the role of cooling the heat absorber and the cylinder wall. The liquid piston type gas compressor improves the cooling capacity of the piston gascompressor as much as possible, makes the compression process of the liquid piston gas compressor approach ideal isothermal compression as soon as possible, and reduces the power consumption of the piston gas compressor.

Description

technical field [0001] The invention belongs to the field of gas compressor manufacturing, and in particular relates to a piston type gas compressor. Background technique [0002] The existing piston gas compressors have been using the traditional cylinder and piston structure, and the cooling methods of the existing piston gas compressors are air cooling and water cooling, both of which are for cooling the cylinder body, and the cooling of the compressed gas is not sufficient. It is far away from the ideal isothermal compression, and the power consumption is large. Contents of the invention [0003] The invention provides a liquid piston gas compressor, at least solving one technical problem in the background art, which improves the cooling capacity of the piston gas compressor as much as possible, so that the compression process of the liquid piston gas compressor of the present invention is as close to ideal as possible Isothermal compression, and reduce the power cons...
