一、前 言 近几年,随着迅速地推进各种设备的合理化和大容量化,对被称为开动设备心脏部位的压缩机的要求条件越来越严格。尤其是要求能够长时间连续运转易于保养维修,而且维修费用低等,这些是设备用压缩机的必要条件。 下面,分别讲一讲往复式压缩机和离心式压缩机最近的发展动向及存在的问题。 I. INTRODUCTION In recent years, with the rapid promotion of the rationalization and capacity increase of various equipment, the requirements on the compressor, which is called the heart of the starting equipment, have become more and more stringent. In particular, it is required to be able to operate continuously for a long period of time and to be easily maintained and repaired, and the maintenance cost is low, which are necessary conditions for compressor for equipment. Next, talk about the reciprocating compressor and centrifugal compressors, the recent developments and problems.
