Research on Domestic Maintenance of an Imported Expansion Compressor Unit
The expansion compressor unit of a natural gas processing plant encountered water intrusion,resulting in corrosion of the impeller and main shaft,which seriously affected the normal operation of the equipment.After decomposing the unit,two maintenance strategies are put forward:direct repair of damaged parts and local repair of parts.After comparing and analyzing the advantages and disadvantages of the two repair schemes,the local maintenance scheme is selected for unit maintenance,and some parts are reformed domestically.Practice has proved that the unit repaired by the localization maintenance strategy not only runs well in practical application,but also its performance is similar to that of the equipment before transformation.
