A TECHNICAL NOTE ON THE EFFECTS OF SUCTION CHAMBER AND CELL INTERACTION ON THE SUCTION CHARACTERISTICS OF A ROTARY VANE COMPRESSOR

摘要

In most sliding vane air compressors, the angular span of the suction port is usually larger than that of an individual cell. Hence two or more cells may communicate simultaneously with the suction plenum chamber during the suction process. Because of this, the suction process in this type of compressor is a continuous process and pulsation effects are small compared to those found in reciprocating compressors. This paper illustrates a theoretical study of the suction characteristics of a sliding vane compressor by accounting for the effects of the interaction between the "ceil-in question" and its neighbouring cells (during the suction process) as well as the suction plenum chamber. The variations of pressure temperature and air mass flow into and/or out of each of the neighbouring cells and the suction chamber during the suction process are shown and discussed together with those of the "cell-in question".
