Z-type CNG Compressor

Detailed Product Description

1 Vertical structure. Small floor space
2. Core line of cylinder is vertical to the ground, cylinder wall cannot bear the gravity of piston assembly. Cross head sliding path cannot bear the gravity of cross head assembly. Lubricant oil drops (haze) wont gather at one side because of gravity, spread everywhere. The friction of cylinder and piston and packing is small and equal. The sealing condition is best, which can extent the using time of cylinder.
3. The bend rod of mutual row compressor arranged in alternate angle ( 2 rows in 180°3rows in 120°) One bend turn accompanies with one row cylinder. The reciprocating inertia force keeps balance with rotating inertia in the machine. The property is easy to maintenance and less vibration.
4.Cylinder and packing are made of nonlubrication substance and oil free lubricating structure. The advantage is no oil, no pollution to natural gas and low cost. If using this machine, standard natural gas filling station produces 10,000 squares each day can save more than 1800kg lubricant every year.
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.The pad valve was awarded national scientific progress prize. 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 .The cylinder and packing are cooled by forced input water and cooling effect is good.
8.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 separatable, the water dust is easy to clean.
    The air cooler of mixed cooling compressor assembly is packing on the compressor .The closed water cooling system holds small floor space suits the northern area and small CNG filling station.
 9. 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 saf
