CNG son-station compressor

 
 
       
 

2 Applications
The model of D-0.28/ (30-200)-250 unit is skid-mounted with the main frame and auxiliary unit are installed on the same skid which is covered with acoustic enclosure. Within it is equipped with Ex-proof lamp, exhaust fan, anti-electrostatic instrument. The structure of the compressor is symmetrical balanced reciprocating piston type, two-stage compression. The tandem cylinder on the working throw, balance throw on another which is used to balance reciprocating inertia force and reduce unit vibration.
The cooling type is air-water combination cooling. The packing of cylinder and piston rod is less oil lubrication. The unit can directly refuel the vehicle with high or low pressure and refuel the storage tank with middle or high pressure bank through the control the priority sequence control system .
