| Abstract: | The frequent leaking occurred in the operation of metal bellow seal in asphalt pump(double screw pump) in propane deasphalting unit,the analysis concluded that the seal wearing and coking on the bellow seal are the culprits of failure.The optimization of operation has effectively solved the problems of evacuation of asphalt pumps due to the propane carry-over in asphalt,operating environment of bellow seal has been greatly improved,and revamping of seal installation has reduced the work load of screw pump m... |
