This post was last edited by yxmqh on 2010-4-16 at 15:35. Our factory has reciprocating compressors such as 6D32, 6M32, and 2D12M. I would like to ask what the differences are between D-type compressors and M-type compressors?
The M-type compressor features a symmetric arrangement of cylinders, with all cylinders located on one side of the motor. It is also called type D when there is only a pair of cylinders arranged symmetrically. Type D is a type of Type M.
According to the JB 2589-1986 standard, the “M type” is of the symmetrically balanced design, horizontal in layout, with the motor located at one end of the crankshaft； “The “D-type” is a two-column symmetrically balanced compressor.
The answer above is correct; additionally, the number following M indicates the piston force.
I’ve learned it; it’s useful. Thank you, OP
I have a question: in my unit, 3D22 features 3 columns arranged symmetrically
As a supplementary note, the D type represents a symmetrically balanced design, with cylinders located on both sides of the compressor; it consists of two rows of cylinders. The M type is also symmetrically balanced, and can have four or six rows of cylinders. The M type is equivalent to two D types combined, and it has a wider range of applications
After learning it, everyone becomes an expert; I had never heard of this before
