Description

technical field [0001] The invention belongs to the technical field of air compressors, and in particular relates to an air compressor. Background technique [0002] With the large-scale application of large-scale mechanical equipment, the use of hydraulic drive technology in the field of air compressor application technology is becoming more and more mature. 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 of this method is large, unstable, and it is easy to get stuck under severe working conditions. In addition, most of the reversing valves that realize the reciprocating motion of the piston in the current hydraulic air compressors use electromagnetic reversing valves and displacement sensors to match each other. Cooperate with the control of the reversing, the sensor is controlled by the proximity switch, the reversing i...

[0002] With the large-scale application of large-scale mechanical equipment, the use of hydraulic drive technology in the field of air compressor application technology is becoming more and more mature. 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 of this method is large, unstable, and it is easy to get stuck under severe working conditions. In addition, most of the reversing valves that realize the reciprocating motion of the piston in the current hydraulic air compressors use electromagnetic reversing valves and displacement sensors to match each other. Cooperate with the control of the reversing, the sensor is controlled by the proximity switch, the reversing is unstable and unreliable; the control circuit part of the reversing device is controlled by the circuit board, because the circuit board is a non-standard part, and it is difficult to manufacture and process, and repair after damage It is very difficult; if the existing reversing device is continuously energized for a long time, it is easy to damage small devices and cannot meet the requirements of long-term energization, which also affects production efficiency to a certain extent
