water cooling CNG compressor

1.The assembly takes 2 threads symmetry structure. and 2 cranks in 180°. The to and for inertia force keeps balance with rotating inertia force. This assembly runs well and not vibrates. 2.Cylinder level symmetry structure, oil free lubricating structure of cylinder, packing can save more than 25% of oil comparing with other oil lubrication compressor in China. 3. High-pressure packing seal technology, which can save more than 10% power, are taken into use. 4.Compressor assembly is packing whole and driven by elastic coupling of motor, easy to transport and install. 5.Piston ring and packing seal assembly take polytetra fluoroethylen (PTFE) non-oil lubricating materials, wearable and low maintenance cost and wont bring virulent accidence such as pulling cylinder. 6 Cushion efficiency produced by cushion key can reduce the inpingement from valve plate made of stainless steel materials. The valve spring was imported from Sweden. 7.Crosshead supporting face is covered with Babbitt alloy steel that is wear-resisting. 8.The cylinder jacket is pre-mask jacket, small friction rates. The friction among cylinder, piston ring and support ring is small, which can extend the using time of the assembly. 9.Cooling style is water-cooling or mixed cooling (wind cooling and closed water cooling) and choose able: Water-cooling compressor assembly takes separatable pipeline cooler. The air flows in the pipe and water outside. The water gas walks in opposite direction. The structure of the assembly is small and beautiful. The pipe core is seperatable, the water dust is easy to clean. 10.The air cooler of mixed cooling compressor assembly is packing on the compressor .The closed water-cooling system holds small CNG filling station. 11.Control system of compressor is composed of PLC writable controller of Siemen and soft driven starter, which can inspect the work of compressor assembly to ensure the assembly working safely.
