摘要
影响螺杆式压缩机排气量的主要因素有两个 :压缩过程中制冷剂泄漏和制冷剂被预热。这两个因素直接与螺杆的形状和加工精度、压缩过程中螺杆被冷却的程度等有关。由于各厂家的螺杆设计和加工技术千差万别 ,因此难以用计算方法确定螺杆式压缩机的容积效率。笔者通过对螺杆式压缩机容积效率的主要影响因素的分析 ,推导出容积效率的计算方法 ,经验证此方法可用于工程设计。
It is two main factors that the refrigerant leakes and preheated in compress process for the discharging of the screw refrigeration compressor. The size of them directly is related to the form of the screw and the precision of the screw processed, and the screw cooled etc. Each compressor factory is different from others for designing and processing the screw. In the engineering design, it is difficult to calculate volumetric flow rate of the screw refrigeration compressor. The main factor of the volumetric flow rate is analyzed for the screw refrigeration compressor. A method of calculating the volumetric flow rate is inferred and checked. It can be for the use of engineering design
