攀钢焦化厂尿素工段有两台2D8-14/35型CO_2压缩机,从1991年开工以来,一直存在压缩机进排气阀更换频繁,造成压缩机经常性停转,严重影响正常生产。而现场拆下来的进排气阀,反映出的问题,经常性的存在于阀座与阀片间的密封不严,造成漏气。开始,直接用人工方法让阀座端面在研磨平台上研磨,但是由于阀座底凸台很短,直接
There are two 2D8-14 / 35 CO_2 compressors in the urea section of Panzhihua Coking Plant. Since 1991, there has been frequent replacement of the compressor intake and exhaust valves, causing the compressor to stall frequently and seriously affecting normal production. The on-site demolition of the intake and exhaust valve, reflecting the problems, there is often the valve seat and the seal between the valve lax, resulting in leaks. The beginning, the direct use of artificial methods to seat the end surface grinding on the ground, but because the seat bottom boss is very short, direct
