发展经过过去十年中,在高压领域内,离心式压缩机已经向往复式压缩机提出挑战。由于对高压压缩机在容量、气量及功率的要求增长,也就是说,要建造更大的肥料(氨)厂,而且要求成本低,设备经济,因而促使离心式压缩机进入了迄今为止被认为是往复式压缩机所独占的领域。但是,还有一个领域仍由往复式占领。这就是很高压力的领域,本文取此压力平均高于1500巴(1巴=1.019公斤力/厘米~2—译注),而目前工业用往复式压缩机的上限,约为4000巴。
Development Over the past decade, centrifugal compressors have challenged reciprocating compressors in the area of high pressure. Due to the increased capacity, gas and power requirements of high pressure compressors, that is, the need to build larger fertilizer (ammonia) plants, with low costs and equipment availability, has prompted centrifugal compressors to hitherto be considered Reciprocating compressor is the exclusive area. However, another area is still occupied by reciprocation. This is a very high pressure area, and in this paper, the pressure is taken to be above 1500 bar (1 bar = 1.019 kgf / cm²) on average, and the current upper limit for industrial reciprocating compressors is about 4000 bar.
