| Abstract: | In the desolventing unit of phenolic epoxy resin production, gear pump of the falling film evaporator pump and pelletizer feeding runs under high temperature and high viscidity and vacuum. Concerning with the problems such as difficult operation of manual jigger, bad seal of stuffing box, severe leakage, short span of the stuffing, and quicker abrasion of pump's axis, reasons which causes for these problems are analyzed. Improvement is made on the stuffing box seal and better result is obtained in combination with the application of sealing of skeleton oil seal. |
