我厂使用的氮氢气压缩机的刮油环漏油,故对其刮油装置的内部结构进行了较大的改造。首先是增加了一只阻油环,把十字头体飞溅和活塞杆带入的绝大部分润滑油挡住,其次是改用重量较轻的材料做刮油环座,克服了刮油环座体因自身重量而下坠的问题,使刮油环与活塞杆的表面接触贴合得更加均匀严密,从而达到理想的刮油效果 (见附图)。于1991年1月14日投入运行至今无一点漏油痕迹。 Nitrogen hydrogen compressor used in our factory scraping the oil ring leakage, so its internal structure of the scraping device made a major transformation. The first is to add an oil ring, the crosshead splash and piston rod into most of the oil block, followed by the use of lighter weight material to do oil scraper ring seat to overcome the scraper ring seat Due to its own weight and the problem of falling, the wiper ring and the surface of the piston rod contact with a more uniform and close fit, so as to achieve the desired oil scraping effect (see photo). January 14, 1991 put into operation so far no trace of oil spills.
