| Abstract: | It analyzes the hydrogenation seal compressor dry gas seal common damage expiration ways.Based on the examples,the reasons of dry gas seal pollution are analyzed,dry gas seal air-supplying system improvement and structure improvement are proposed,after that,the compressor runs well.Three measures adopted,such as reprocessing the bearing cavity,establishing the logical control system and the second-level discharge outlet opened in the sealed chamber upper side,it proposes dry gas seal air-supply system impro... |
