压缩机是负压原油稳定装置的关键设备。为了提高稳定装置的效率,河南油田江河联合站的原油稳定装置先后采用了天津压缩机厂生产的 LG16-5/3.5、LG16-10/3.5型压缩机,及从英国豪顿公司进口的 HI204型(额定排气量20m~3/min)螺杆压缩机。从使用情况看,两者都具有操作弹性大,运转平稳的优点,且都能满足装置的设计要求。但进口机组更具有压缩效率高、自动保护齐全、灵敏、维护工作量小、运转时间长等优点;缺点是配件昂贵。通过对比,可比出进口压缩机与国产压缩机的优劣,同时也可达到对进口压缩机进行消化吸收,以促进国产压缩机更新改造之目的。
Compressor is the key equipment of negative pressure crude oil stabilizer. In order to improve the efficiency of the stabilizing device, the crude oil stabilizing device at the Henan River Joint Station has adopted the LG16-5 / 3.5, LG16-10 / 3.5 compressors from Tianjin Compressor Factory and the HI204 from Howden, UK (Rated displacement of 20m ~ 3 / min) screw compressor. From the usage point of view, both have the advantages of flexible operation, stable operation, and can meet the design requirements of the device. However, the imported unit has the advantages of high compression efficiency, complete automatic protection, sensitivity, small maintenance workload and long operation time. The disadvantage is that accessories are expensive. By comparison, the advantages and disadvantages of imported compressors and domestic compressors can be compared, but also to achieve the purpose of digestion and absorption of imported compressors in order to promote the renovation of domestic compressors.
