随着现代空间技术、国防、化工、石油炼制、食品以及医药工业的迅速发展,对压缩机气缸实现无油润滑的要求愈来愈迫切。在尿素生产中,对CO_2压缩机气缸也同样迫切需要实现无油润滑。压缩机气缸实现无油润滑,不但可以简化装备,降低成本,节省大量高级润滑油,而且可以防止汽提法尿素流程高压洗涤器 With the rapid development of modern space technology, defense, chemical industry, petroleum refining, food and pharmaceutical industry, there is an increasing demand for the compressor cylinder to achieve oil-free lubrication. In urea production, there is also an urgent need to achieve oil-free lubrication of CO 2 compressor cylinders. Compressor cylinder oil-free, not only can simplify the equipment, reduce costs and save a lot of high-grade lubricants, but also to prevent the stripping process of urea pressure washer
