石油地质专业管理局的具有2CГД型高压压缩机的第17号压缩机站,对工作介质随压缩机工作时间的延续,通过塑料和铸铁填料环发生泄漏的过程进行了研究。采用空气作为工作介质。填料环用AФГM塑料和C428-48铸铁制成;机器曲轴转速为365转/分,由转速计测得,并在各次测定中均保持不变。已知,2CГД型单作用压缩机具有两个并列的缸,并具有回水装置。一个气缸装设铸铁填料环,另一个气缸装设塑料的。对于某几种结构型式,只是在安装于中体
The No. 17 compressor station with a 2CГД-type high-pressure compressor of the Bureau of Geo-Administration of Geology has studied the process of working medium with leakage of plastic and cast iron rings due to the continuation of compressor working time. Using air as the working medium. The packing rings are made of AФM plastic and C428-48 cast iron; the crankshaft speed of the machine is 365 rpm and is measured by a tachometer and remains constant for each measurement. It is known that the 2CГД single-acting compressor has two juxtaposed cylinders and has a return device. One cylinder is fitted with a cast iron packing ring and the other cylinder is filled with plastic. For some types of structures, only installed in the body
