How are the rows and stages of reciprocating piston compressors divided? How can you determine the number of columns and stages from the compressor model?
One compression cycle is considered one stage; the number of compression cycles determines the number of stages. Regarding model designations such as 4M20-5.2/20-187, the 4M indicates a compressor with four columns, while 20 denotes that the total piston force is 20 tons； The values indicated by different manufacturers are not entirely consistent; they all represent parameters related to pressure and flow rate. For 2D20-6.83/160-185, the same rule applies: 2D denotes two rows of compressors, while 20 indicates that the total piston force is 20 tons ； The values shown by different manufacturers for these parameters are not entirely consistent; they all represent pressure and flow rate values
