第一章 绪 论 一、概述 气体压缩机如以压力划分时,一般的划分原则是:压力为2-10大气压的称为低压压缩机;压力为10-100大气压的称为中压压缩机;压力为100-1000大气压的称为高压压缩机,而1000大气压以上者称之为超高压压缩机。本文仅就国外超高压压缩机的发展概况及其发展趋向等作一概括介绍。 超高压压缩机的应用范围也是比较广泛的,如很早就用来压缩氢气、氮气。近年来随着科学技术的不断发展,尖端技术的不断涌现,国防工业的迅速发展,化学工业中高速度发展起来的高分子合成工业的形成,特别是近年来高压法聚乙烯的出现和发展,给超高压压缩机的应用开辟了更为广濶的前景。目前就世界范围看,超高压压缩机的主要应用是在高压法聚乙烯的生产上。下面概要介绍一下高压法聚乙烯的一些情况。
The first chapter introduction First, an overview of the gas compressor, such as pressure division, the general principle of division is: pressure is 2-10 atm called low pressure compressor; pressure is 10-100 atm compressor called pressure; pressure For 100-1000 atmospheric pressure called high-pressure compressor, and 1000 atmospheres above referred to as ultra-high pressure compressor. This article only summarizes the development of ultra-high pressure compressor abroad and its development trend. Ultra-high pressure compressor is also widely used, such as long used to compress hydrogen and nitrogen. In recent years, with the continuous development of science and technology, the continuous emergence of cutting-edge technology, the rapid development of national defense industry, the rapid development of chemical industry in the formation of polymer synthesis industry, especially in recent years, the emergence of high-pressure polyethylene and development, to The application of ultra-high pressure compressor has opened up a broader perspective. Currently on a global scale, the main application of EHV compressors is in the production of high-pressure polyethylene. Here’s a brief overview of some of the high pressure polyethylene.
