Z(vertical) type compressor cylinder which do not bear the weight of the working conditions of piston is conducive to high-pressure cylinder without oil lubrication structural design, no oil (less oil) lubrication operation, higher mechanical efficiency, extended service life of cylinder and piston rings to reduce the running costs.
All cylinders are equipped with dry cylinder liner wear resistance.
Compressor has three throws and three cylinders in line, no string-cylinder, and the corresponding packing & the large end bush with the maintenance window, and set up in the skid side, good maintainability.
Small installation area, easy to transport, saving investment.
Two-throw symmetrical balanced horizontal units, throw’s alternate angle to each other 180° the inertial force balance, the piston force distribution, performance and running balance.
By the finite element analysis software simulation load compressor design the overall movement of compressor body, the compressor body and midbody as a whole structure, uniform load transfer, the overall rigid body excellent.
Compressor body with windows for disassembly and inspection of crosshead, etc., to facilitate inspection and maintenance.
Compressor body with oil level gauge, if necessary, can be equipped with platinum thermal resistance and electric heaters, oil testing, oil level, and interlock with the unit running.
With pre-lube oil pump, moving parts of a mandatory pre-lubrication to ensure a reliable operation. D type compressor can be adapted in daughter station, mother station and standard station.
M-type (4-throw or 6-throw above) symmetrical balance compressor is the best balance of performance one in various types of piston compressor.
The inertia force (a first and second order) and the moment of inertia can be completely balanced, uniform shear force, in particular a smooth operation.
The strength of the relative two throws piston in opposite directions, offsetting each other, thereby substantially improving the neck axis (bearing) stress conditions, a decrease of the main axis between the neck and main bearing wear and prolongs the service life.
The more throws, and can be one throw for one stage, one stage for one cylinder. Rigid run good, fast and convenient maintenance overhaul.
Adapt to the larger discharge capacity, the needs of multi-stage compression is the large discharge capacity of gas or CNG mother station with the best type of compressor.
