An experimental study of the dynamic equivalence leakage of rolling-piston compressors

摘要

Based on the rolling-piston compressor as the research object, in this work, a new type of dynamic equivalence testing device for the compressor is put forward, which simulates the working condition of the inside compressor cavity and accomplishes dynamic adjustable speed, controllable differential pressure, and variable clearance. More groups of experiments with dynamic changes of multi-factors are carried out and finally the quantity and regularity about the leakage change with speed, differential pressure, and clearance are obtained.
