Problems solved by technology

Especially in the field of air compressor application technology, the traditional air compressor uses a crank-connecting rod mechanism to realize the reciprocating movement of the piston in the cylinder and then compress the air. The output pulse of the air compressor in this way is large and unstable. It is easy to get stuck under severe working conditions. In addition, most of the reversing valves that realize the reciprocating movement of the piston in the current hydraulic air compressors use electromagnetic reversing valves and displacement sensors to control the reversing, and the sensors are controlled by proximity switches.

Abstract

The invention discloses a hydraulically-driven reciprocating air compressor. The hydraulically-driven reciprocating air compressor comprises a connecting block, and a first cylinder body and a secondcylinder body are installed at the left end and the right end of the connecting block correspondingly. A piston rod is connected in the connecting block in a sliding mode, the left end of the piston rod is located in the first cylinder body, and the right end of the piston rod is located in the second cylinder body. A first piston connected with the left end of the piston rod is connected in the first cylinder in a sliding mode, and a second piston connected with the right end of the piston rod is connected in the second cylinder body in a sliding mode. The connecting block is provided with areversing valve for controlling the left-right reciprocating motion of the piston rod. A first one-way valve and a second one-way valve for controlling air exhausting are installed at the left end ofthe first cylinder body, and a third one-way valve for controlling air feeding and a fourth one-way valve for controlling air exhausting are installed at the right end of the second cylinder body. Theoverall connecting structure of the first cylinder body and the second cylinder body of the air compressor is more compact, and the reciprocating motion of the piston is free of electric control.

Description

technical field [0001] The invention relates to the technical field of air compressors, in particular to a hydraulically driven reciprocating air compressor. Background technique [0002] With the large-scale application of large-scale mechanical equipment, hydraulic drive has been widely used as a very important driving method, and the hydraulic system and its related technologies are becoming more and more mature. Especially in the field of air compressor application technology, the traditional air compressor uses a crank-connecting rod mechanism to realize the reciprocating movement of the piston in the cylinder and then compress the air. The output pulse of the air compressor in this way is large and unstable. It is easy to get stuck under severe working conditions. In addition, most of the reversing valves that realize the reciprocating movement of the piston in the current hydraulic air compressors use electromagnetic reversing valves and displacement sensors to contro...
