摘　　要：在分析不同类型压缩机的润滑油控制要求的基础上,从产品设计的角度出发,给出了并联机组的油平衡设计方案。涡旋并联机组和螺杆并联机组适宜采用高压回油方案,活塞并联机组适合采用低压回油方案。此研究为并联机组的设计、制造和推广应用提供了依据。Based on the analysis of oil control requirements for different types of compressor and fl＇om the view of product de- sign, a design scheme of oil equilibrium of parallel compressor units was proposed. The scheme of oil return under high pressure difference was suitable for parallel compressor units with scroll or screw compressors, that of oil return under low pressure differ- ence was suitable tbr parallel compressor units with reciprocating compressors. The study could provide the basis of design, manu- facture and application of parallel compressor units.
