AI Technical Summary
The existing rotor shaft seal of the slag crusher requires complete disassembly and maintenance when leakage occurs, which makes maintenance difficult.
The auxiliary shaft seal is a split-type detachable seal, including an inner pressure cover, a first sealing layer, an auxiliary sealing layer, and a second sealing layer. Combined with the installation mechanism, it achieves triple sealing and is cooled by a cooling tank. The sealing layer has a split structure for easy disassembly.
It enables quick disassembly and replacement of sealing components in case of leakage, reducing maintenance time, extending service life, and avoiding disruption to equipment operation due to maintenance.
