回转式螺杆压缩机的润滑方法
摘要：
本发明关于一种以酯为基础的润滑油，其是用于利用不含氯的氢氟碳化物(HFC)冷冻剂例如R-134a的回转式螺杆压缩机，该以酯为基础的润滑油含有由三季戊四醇与混合的C5-C10单羧酸的反应获得的产物或由二季戊四醇与混合的C5-C10单羧酸的反应获得的产物及任意地由二季戊四醇与C5单羧酸的反应获得的产物。
摘要（英）：

The invention relates to ester-based lubricating oil which is used for a rotary helical screw compressor employing a hydrofluorocarbon (HFC) refrigerant not containing chlorin, such as R-134a. The ester-based lubricating oil contains a product obtained through reaction of tripentaerythritol and mixed C5-C10 monocarboxylic acid, or a product obtained through reaction of dipentaerythritol and mixed C5-C10 monocarboxylic acid and a product obtained through random reaction of dipentaerythritol and C5 monocarboxylic acid.
