摘要： The present invention provides a screw compressor in which an oil path is provided within the casing body such that the oil for sealing gaps in the compression chamber and lubricating the bearings is circulated to the vicinity of the low pressure side, allowing the compressor to have high adiabatic efficiency and high volumetric efficiency. The present invention also provides a screw compressor in which an oil path is provided in the screw bore outer circumferential portion of the casing body to prevent contact between the screw rotor and the screw bore portion of the casing body. The present invention also provides a screw compressor which includes a heat sink to increase the heat transfer area for exchanging heat between the oil and refrigerant gas or liquid refrigerant, thereby achieving increased resistance to returned liquid refrigerant.
摘要翻译：本发明提供一种螺杆式压缩机，其特征在于，在所述壳体内设置油路，使得用于密封所述压缩室中的间隙的润滑油和润滑轴承的油循环到所述低压侧附近，使得所述压缩机具有高绝热效率和高体积效率。本发明还提供一种螺杆式压缩机，其特征在于，在所述壳体的螺纹孔外周部设置有油路，以防止所述螺杆转子与所述壳体的螺纹孔部接触。本发明还提供了一种螺杆式压缩机，其包括散热器，以增加用于在油和制冷剂气体或液体制冷剂之间交换热量的传热面积，从而实现对返回的液体制冷剂的增加的阻力。
