本文根据实测结果,论述了因测定时所用工况不同而引起的压缩机排气量的偏差,提出了既能满足船舶规范要求,又能做到经济合理地选用压缩机的原则。本文还介绍了采用淡水闭式冷却时所用的冷却水的温度和流量,以及验证试验的结果。可供选用和设计压缩机时参考。 Based on the measured results, the disagreement of displacement of the compressor caused by the different working conditions is discussed. The principle that the compressor meets the requirements of the ship norms and the compressor can be economically and reasonably selected is put forward. This article also describes the temperature and flow of cooling water used for closed cooling with fresh water, as well as the results of verification tests. Available for selection and compressor design reference.
