一、概 述 燃气摩托式压缩机自一九三七年开始生产以来,随着天然气开采事业的发展,这种型式的压缩机已有很大发展。其基本结构型式有两种:1.狭义型式（整体式）——发动机与压缩机共曲轴,完全成一个整体;2.广义型式（可分式）——发动机与压缩机曲柄分开,用联轴器连接。七十年代以来,特别是七五年以来,用于气田井口增压及天然气集输的燃气摩托式压缩机的装配及冷却形式趋于撬装及间接风冷。 First, an overview of gas-powered compressor since 1937 began production, with the development of natural gas exploration, this type of compressor has been greatly developed. The basic structure of the type in two ways: 1. Narrow type (monolithic) - The engine and the compressor crankshaft, completely into a whole; 2. Generalized type (separable) - Engine and compressor crank separately, with the joint Shaft connection. Since the 1970s, especially since 1975, the assembly and cooling of gas motor-driven compressors used for gas field wellhead pressurization and natural gas gathering and transport tend to be skid mounted and indirect air-cooled.
