Vibration analysis in reciprocating compressors

Valve Losses in Reciprocating Compressors

Vibration Analysis of Rotary Compressors

By theoretically analyzing dynamic behavior of the crankshaft, the rolling piston and the blade inrolling-piston rotary compressors, constraint forces and sliding speed at each pair of movable machine elements were obtained, and unbalanced inertia forces and compressor vibrations were evaluated. It was concluded that theoretical results have a goodagreement with experimental ones. Moreover, it ...

Rod Loading of Reciprocating Compressors

Design Of Journal Bearings In Reciprocating Compressors

Journal bearings in hermetic reciprocating compressors are analyzed experimentally as well as numerically. The motor current and the load applied to the bearing are measured to obtain the performance curve of the journal bearing, from which the critical Sommerfeld number is derived. In the numerical analysis, the Reynolds equation and equilibrium equations of the journal center are solved simul...

Liquid Slugging Measurements in Reciprocating Compressors

Several different methods of measuring cylinder pressures generated during liquid slugging in Hermetic and Semi-Hermetic compressors have been devised. The methods are discussed and compared, and test results are presented. Some interesting aspects of liquid slugging are also discussed. An empirical relation for predicting maximum cylinder pressure aa a function of compressor power, bore size, ...
