一、正确选用压缩机新装及更新压缩机时应选择节能型压缩机,遵循的原则如下:一是了解压缩机的性能、使用范围、主要参数,看其是否能满足使用工况的要求;二是节能型压缩机在设计时已经考虑了一定的裕量,因此,在选型时不必再考虑压缩机的裕量,应选在使用工况额定值的附近;三是压缩机的附属设备应与主机配套,要充分考虑压缩机的安装及配管要求和配件的供应等问题;四是要考虑节电效益,投资回收期限要小于1/2～2/3的压缩机寿命周期.
First, the correct choice of compressor New compressor and compressor should be updated to choose energy-saving compressor, follow the principles are as follows: First, understand the performance of the compressor, the use of the main parameters to see whether it can meet the requirements of the working conditions; Is the energy-saving compressor has been designed in the design of a certain amount of margin, so in the selection no longer have to consider the compressor margin, should be selected in the vicinity of the rated working conditions; Third, the compressor should be attached to the equipment should And supporting the host, we must fully consider the compressor installation and piping requirements and supply of spare parts and other issues; Fourth, to consider the power-saving benefits, investment recovery period of less than 1/2 ~ 2/3 compressor life cycle.
