离心式压缩机的轴端密封是设计和制造中的主要技术问题之一。实践证明,试验数据和实际运行数据有较大的差别。我厂通过对几台产品的设计、试验和运行实践,摸索到浮动环油密封的一些规律,认为要克服这种现象,必须考虑以下几个方面。 1.有关参数的选取泄漏量是决定密封性能的主要参数。就当前国内外机组的运行情况来看,内漏量还满足 Centrifugal compressor shaft seal is the design and manufacture of one of the major technical issues. Practice has proved that there is a big difference between experimental data and actual operating data. I plant through several product design, test and operation practice, to explore some of the laws of the floating ring oil seal that the need to overcome this phenomenon, we must consider the following aspects. 1. The selection of parameters Leakage is the main parameter that determines the sealing performance. On the current operation of units at home and abroad point of view, the amount of leakage is also satisfied
