L-piston compressor is widely used in domestic mining enterprises to mine air compressor to provide a steady brand manufacturers for wellhead cradle, security doors, put oblique lifting beam, with a variety of motives wind, dust pipeline ash mixing and other facilities. Air compressor room general mounting arrangement of air compressors, air pressure lines in parallel mode. Each compressor including temperature, pressure, including a total of up to 10 parameters need to be constantly monitored, there is more than one compressor dozens or even hundreds of state parameters. Because the console is a separate compressor arrangement in place, so the compressor inspection tour, start-stop control operation to bring a lot of trouble, not only the workload, and not easy to be observed in the operation of the air compressor state. High temperature saturated air first enters the pre-cooler cold and dry, with the pre-cooler from the local dry cold evaporator heat exchange air compressor manufacturers, reduce the temperature to obtain preliminary into the evaporator, air In a second evaporator in heat exchange with the refrigerant vapor, the temperature was further reduced to close to the refrigerant evaporation temperature; in the two cooling process, the compressed air saturated water vapor can be condensed into liquid water droplets into the air and gas water separator, the separator separates the liquid through the automatic drain (not shown) from the plane of large air compressor manufacturers, low temperature drying compressed air is returned to the pre-cooler compressor manufacturers, wholesale, and just entering the saturated air by heat exchange, so that the temperature itself is improved, so that the dryer vent to give a lower moisture content (i.e., low dew point) at the same relative humidity lower drying compressed air. From the above analysis, the pre-cooler, evaporator and air-water separator is cold and dry compressed air flow system hollow three components. Air compressor manufacturers, wholesale, Qin Wei Air (certified), Yichun air compressor manufacturers to provide the Compressor Co., Ltd., Xianyang Qin Wei. Xianyang Qin Wei Compressor Co.
