How are the suction and discharge pressures of a reciprocating compressor formed?
Thread Content
A two-stage compression reciprocating compressor normally draws in 2.0 at the first stage, 4.0 at the second stage, and 8.0 at the final stage. If the suction pressure becomes 3.0 and the back pressure at the secondary outlet remains unchanged, what will be the exhaust pressure at the primary stage? If the suction pressure remains constant and the back pressure at the secondary outlet becomes 10.0, what will be the exhaust pressure at the primary stage?
I guess, since you’re not a designer, just follow the parameters specified in the instructions. The principle is the series connection of two or more piston compressors. The working capacity at different levels and the required cylinder diameter are not the same; it’s not calculated on a proportional basis as one might think. For reference.
Is the operating condition of the compressor fixed once it leaves the factory? The inlet pressure is 2.0 and the outlet pressure is 8.0. Can’t it be changed?
