文档介绍：单螺杆式压缩机主要结构和工作原理星轮排气孔口主轴星轮单螺杆转子机壳吸气腔星轮星轮两星轮旋转方向相反,分别以轴平面为界的两个工作腔工作单双螺杆压缩机比较相同点:定内容积比不同点:单螺杆具有双工作腔、运动更平稳压缩过程吸气压缩排气动画片 pact, simple and robust construction Lack of valves or critical ponents increases resistance to liquid slugging and ensures maximum reliability Very low bearing load, well-balanced axial and radial forces by pression with a single rotor and 2 idle turning gate rotors Durable polymer gate rotors eliminate friction and significantly reduce wear and energy losses No oil pump necessary – compressor screw is cooled and sealed pressor by liquid refrigerant injection, resulting in a constant working temperature throughout an extended working life and allowing reduced rotor clearance for accurate and pression Very low vibration levels,
