Problems solved by technology

[0002] At present, positive displacement compressors generally adopt the piston type. Due to the friction between the piston and the cylinder wall, the efficiency of this type of piston compressor is reduced, the life is short, and it is difficult to dissipate heat when the diameter of the cylinder is large.

Embodiment Construction

[0009] exist figure 1 Among them, the cylinder (5) is equipped with a pressure transmission liquid, and the top of the cylinder (5) is respectively connected to the inlet port (2) and the exhaust port (1) through the inlet check valve (3) and the exhaust check valve (4). , the bottom of the cylinder (5) communicates with the pump (7) through the reversing valve (6). The cylinder (8) is equipped with a pressure transmission liquid, and the top of the cylinder (8) is respectively connected to the air inlet (2) and the exhaust port (1) through the intake check valve (10) and the exhaust check valve (9). (8) The bottom is connected to the pump (7) through the reversing valve (6).

[0010] During work, start the pump (7) to pump the pressure transmission liquid in the cylinder (5) into the cylinder (8). At this time, the intake check valve (3) on the top of the cylinder (5) is opened, and the exhaust check valve ( 4) close, carry out suction, the exhaust one-way valve (9) of cyli...

Abstract

Disclosed is a compressor with a liquid piston. Suction and exhaust of a cylinder are achieved by replacing traditional piston motion with ascending and descending of liquid driven by a pump in the cylinder, friction of a liquid piston with a cylinder wall is much smaller than friction of a solid piston with the cylinder wall, and accordingly efficiency is improved and service life is prolonged. In addition, the liquid piston and the cylinder can be made into a parallel structure of a plurality of small tubes, and accordingly the defect that a traditional cylinder is hard to radiate when diameter is large is overcome and manufacture cost of the compressor with the liquid piston is low.

Description

Technical field [0001] The invention relates to a volumetric compressor, which belongs to the technical field of compressors. Background technique [0002] At present, positive displacement compressors generally adopt the piston type. Due to the friction between the piston and the cylinder wall, the efficiency of this piston type compressor is reduced, the service life is short, and it is difficult to dissipate heat when the diameter of the cylinder is large. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a liquid piston compressor, which uses a pump to drive the liquid to rise or fall in the cylinder instead of the traditional piston movement to realize the suction and exhaust of the cylinder, because the liquid The friction between the piston and the cylinder wall is much smaller than the friction between the solid piston and the cylinder wall, which improves the efficiency and life. In addition, ...
