供油系统和多供油系统螺杆式压缩机的润滑方法

供油系统和多供油系统螺杆式压缩机的润滑方法(中文5700字,英文4600字)
摘要
油液制冷压缩机应用于制冷等系统，在其系统中，由于高温和润滑剂粘度降低而造成的轴承材料强度降低和轴承材料寿命降低的问题已经得到解决。压缩机体的供油系统是由轴承供油系统（在低压下，为压缩机体的每个轴承进行润滑）和油液温控系统（在高压下，为压缩机体进行温度控制）组成。轴承供油系统是一个由油箱、油冷却器和油泵组成的闭环供油系统，油液温控系统是一个由隔油池和油冷却器组成的闭环供油系统。

Lubricant supply system and operating method of multisystem lubrication screw compressor
Sekiya; Yoshimitsu (Moriya, JP)
Abstract
    An oil refrigeration screw compressor being applied to a refrigeration system etc., in which the problem of strength reduction of a bearing material under high temperatures and that of lifetime reduction of the bearing material due to viscosity lowering of lubricant are solved. A lubricant supply system to a compressor body is divided into a bearing oil supply system for supplying lubricant to each bearing of the compressor body at low pressure and into a temperature control oil supply system for supplying lubricant into the compressor body at high pressure. The bearing oil supply system is a closed circuit oil supply system comprising an oil supply tank, an oil cooler, and an oil supply pump, and the temperature control oil supply system is a closed circuit oil supply system comprising an oil separator and an oil cooler.
