螺杆压缩机BC—101是丁二烯抽提装置的核心设备,由西德好望冶金厂(GHH)1979年制造,1986年6月在大庆石化总厂丁二烯装置投入生产运行,因长期漏油,严重困扰着丁二烯装置的生产。BC—101螺杆压缩机原用机械密封为GHH公司产品,结构及安装见图1,主要数据见表1。从1990年8月压缩机首次检修后,7年来虽做了很多工作,但机械密封漏油问题一直没有解决,为此进行了以下技术分析。
Screw Compressor BC-101 is the core equipment of butadiene extraction unit, manufactured by West Germany Hope Metallurgical Plant (GHH) in 1979, put into operation in butadiene plant of Daqing Petrochemical Plant in June 1986, Oil spills seriously haunt the production of butadiene plant. BC-101 screw compressor original mechanical seal GHH company’s products, structure and installation shown in Figure 1, the main data in Table 1. After the first overhaul of the compressor in August 1990, a lot of work has been done in the past seven years. However, the problem of oil leakage from mechanical seals has not been solved. The following technical analysis has been carried out for this purpose.
