Reciprocating compressor models
Thread Content
Could some expert please explain the meaning of the numbers in the model of a reciprocating compressor: what do the numbers 2D16-22.9/23-35 in Shenmu’s models represent?
2D16-22.9/23-35 2: Indicates that there are two compressor rows (2, 4, 6, 8). D: Indicates that the compressor type is opposed-type (D, M, L, P, DZ). 16: Indicates that the compressor’s load capacity is 16T. 22.9: Indicates the exhaust volume in m3/min under inlet conditions. 23-35: Indicates the inlet and outlet pressures in bar(g)
What exactly does bearing capacity refer to? Is it the mass flow rate of the compressor?
This mainly refers to the piston force and the bearing load of the crankshaft.
It’s also a way of indicating the level of load, right?
Yes, generally speaking, this refers to a design load of 16T, which is the designed bearing load for the piston, piston rod, and crankshaft.
I’d like to provide you with some additional information on compressors. Air machines are divided into: 1. Velocity type ； 2. Positive-displacement ； Positive displacement types are further divided into rotary and reciprocating types ； Rotary type: (1) Rotor type ； (2) Screw-type ； (3) Sliding vane type. Reciprocating: (1) Piston type ； (2) Membrane type. Air compressors can be divided into two main categories based on their working principle: positive-displacement and dynamic.
