Analysis and Treatment of Leakage in the Mechanical Seal Water Cooler of the Hydrogenation Extraction Unit Pump
This paper introduces the mechanical seal,flushing mode and water cooler structure in the mechanical seal system of machine pump,and the coil leakage of water cooler in the mechanical seal system of high temperature hot oil pump in the hydroextraction unit.The causes of coil leakage of water cooler of high temperature hot oil pump are analyzed through corrosion mechanism,corrosion type and factors affecting coil corrosion.And listed the water cooler coil material upgrade,from 304 austenitic stainless steel to 2205 two-way steel,the circulating water to debrine,water cooler coil before the factory heat treatment,regular water cooler backwash to prevent coil leakage measures and the effect after implementation.
