Summary of the invention
Complicated for solving existing gas compressor crank linkage driving system, global reliability and the problem such as durability is poor and relatively costly, this utility model provides a kind of piston gas compressor.
nullThis utility model is completed by following technical proposal: a kind of piston gas compressor，Including setting cavity in it、Two ends set the cylinder body of end cap，It is provided with piston in cylinder body cavity，It is characterized in that cylinder body cavity is divided into air cavity and sap cavity by piston，Air cavity end is provided with air inlet pipe and the escape pipe of band check valve，Escape pipe is connected with gas equipment，Sap cavity end is provided with liquid in-out pipe，Liquid in-out pipe successively with solenoid directional control valve、Seal reserving liquid tank to be connected with hydraulic pump，Hydraulic power is provided will pass through hydraulic pump in cylinder body sap cavity，After the gas extruding in air cavity to promote piston to move in air cavity is as pressed gas，Pressed gas is provided to gas equipment，When extracting pressure liquid out sap cavity by hydraulic pump afterwards，Piston moves to sap cavity，Drawn air in air cavity by air inlet pipe simultaneously，So complete a compression to supply gas again the cycle of operation of air-breathing.
Described cylinder body is at least set to arranged side by side two, and the escape pipe of the air cavity end of each cylinder body is all connected with filter inlet end, and filter outlet end is connected with gas equipment；The liquid in-out pipe of the sap cavity end of each cylinder body is respectively a pipe, its outer end is all connected with the liquid in-out mouth of solenoid directional control valve one end, the inlet of the solenoid directional control valve other end is connected with sealing reserving liquid tank by feed pipe, hydraulic pump, liquid outlet is connected with sealing reserving liquid tank by liquid back pipe, alternately hydraulic power is provided to the sap cavity of each cylinder body again will pass through hydraulic pump through solenoid directional control valve, thus alternately the gas in the air cavity of each cylinder body is compressed, to continue to provide compressed gas to gas equipment efficiently, dispelled the heat by sealing reserving liquid tank simultaneously.
The sap cavity end of described cylinder body is provided with pressure transducer, in order to be monitored the pressure in sap cavity by pressure transducer, and then is controlled gas compression process.
Air inlet pipe and the escape pipe of described air cavity end are provided with check valve respectively, can only air inlet, escape pipe can only give vent to anger controlling air inlet pipe.
This utility model has following advantages and effect: alternately can provide hydraulic power to the sap cavity of each cylinder body conveniently by hydraulic pump through solenoid directional control valve, after the gas extruding in air cavity to promote piston to move in air cavity is as pressed gas, continue to provide pressed gas to gas equipment efficiently, not only simplify driving and drive mechanism, and owing to cylinder body volume is bigger, after compression, air cavity remaining space is the least, big compression ratio can be realized, requirement is just can reach, it is to avoid the problem that multi-stage compression structure is excessively complicated by one stage of compression.It addition, this device has the advantages such as caloric value is little, good airproof performance, maintenance rate are low, durable in use, with low cost, an actually preferable gas compressor.
