Corrosive environment and the mechanical seal granular media

Corrosive environment of the mechanical seal
Some of the mechanical seal in a corrosive environment , then only pay attention to the mechanical seal in the corrosion resistance of each of the part itself , but also to prevent them together may be electrically coupled to produce the phenomenon . Corrosive environment of the mechanical seal , to the attention in the selection of corrosion resistant materials . In addition , you can use externally mounted mechanical cable tie. For particularly corrosive prone to accidents , and can double seal , the introduction of barrier fluid to protect them.
The mechanical seal particulate media
Some mechanical seal may contain solid particles of media work , when the solid particles into the friction face , easy to produce severe wear , resulting in failure of the seal faces soon . Another solid particles may cause the snap ring seals can not move axially , so that the ring can not float, losing compensatory , leading to mechanical seal failure . This more effective approach is to add an external flushing device . Since the flushing fluid into the sealed chamber above the seal chamber pressure medium pressure , thus can effectively prevent the particulate media into the sealed chamber . Also you can use double mechanical seal , seal in the middle of adding liquid cable seals chamber . Can also be used externally mounted mechanical seal.
