Summary

 

M-type (4-throw or 6-throw above) symmetrical balance compresser is the best balance of performance one in various types of piston compressor.

 

Advantage

 

  • 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.
     

Function

 

  • M-type with the compressor body& motor positioning measures adopted so that the accuracy of assembly, especially with the compressor motor coaxiality maintain good positioning measures to avoid a period of time to run the compressor motor and the crankshaft on the deterioration of sets of coupling and flexibility lead to early failure, which caused packing, piston rod to reduce the consequences of life.
  • Inlet and outlet of all stage cylinder are arranged downward,making connecting rigid pipe, and pipe vibration small; and all pipelines are arranged on the skid, not only meet national security design specifications, but also easy to identify problems, to facilitate maintenance.
  • All the low-pressure and middle-pressure stages are equipped with inner tube outlet of new-type separator, separation efficiency, making the separated oil and water do not go into the next stage.
  • With the rotor-type lubrication oil pump flow to ensure that the pressure of the moving parte lubricating oll pressure in the 0.4-0.5MPaG run, improves the reliability, extended service life.
  • Can also be used in accordance with user needs to provide the refined ofl filter with the imported filter element to meet the quality of the oil content of CNG request.
