Testing and Evaluation of Rotary Water Seals Wet-Head Continuous Mining Machines.

摘要

Two modes of seal application were indentified,and promising state-of-the-art seals of both types-shaft and drum-were selected for initial rating by non-destructive testing. Only one shaft seal survived the initial test,and a search was made for other candidate seals including new seals. One new type of seal was found that gave promising enough operation,as both a shaft and seal,to be recommended for installation in prototype wet-head machines.
