储运厂乙烯气进口往复压缩机组十字头系统采用十字头与滑道相同材质的结构,在使用过程中出现了配合面拉伤、温度升高连锁停机故障,该机组一开一备,为聚丙烯装置输送原料,2台都发生故障时会导致聚丙烯装置停工等重大事故。我们及时对该机组十字头与滑道进行解体改造,改变了十字头系统材质配合状态,经过计算,合理增大了配合间隙,增大了润滑油槽长度及深度,保证修复后开机试运一次成功。
Storage and transportation plant ethylene gas reciprocating compressor crosshead crosshead system uses the crosshead and slide the same material structure, the use of the surface occurred in the joint strain, the temperature rise interlocking downtime, the unit opened and prepared for the poly Propylene plant transportation of raw materials, 2 have a breakdown will lead to major accidents such as the shutdown of polypropylene plant. We promptly disassemble and reconstruct the cruciform crosshead and the slideway of the unit, changing the cross-head system with the material state, after calculation, reasonable increase with the gap, increasing the length and depth of the lubricating oil tank to ensure that the repair after boot a successful trial .
