Prerequisites for online maintenance of mechanical seals

There is enough space between the shaft sleeve of the mechanical seal and the bearing bracket. The difficulty of online maintenance of the mechanical seal lies in the narrow installation space of the mechanical seal. The general slurry pump mechanical seal can only be seen when the mechanical seal is opened and closed. It is difficult to check the internal compression spring and O-ring of the hard alloy sealing end face. Therefore, to realize the on-line maintenance of the mechanical seal on a large scale, it is necessary to check the space between the slurry pump bearing bracket and the pump body. Carry out appropriate technical transformations so that there is enough maintenance space to implement online maintenance of mechanical seals.

The damaged part of the mechanical seal is the compression spring or O-ring. Once the sealing end face of the mechanical seal is damaged, the mechanical seal will lose the possibility of online repair, and at the same time lose the value of repair. Therefore, if the sealing gland is disassembled It is found that the end face of the machine seal is damaged and can only be replaced with a new machine seal, but the seal end face of the double end face machine seal is made of cemented carbide, which has high hardness and good wear resistance but is brittle, easy to break and disassemble. Be careful not to use brute force to disassemble, the damage of the end face is not easy to occur.　　212.html,
