A, Mechanical seals The installation
Mechanical seal installation must be carried out in strict accordance with the requirements of any installation deviation may lead to system disorders, general installation error can not be more than 0.05 mm of gland, gland and gap error between the shaft or shaft sleeve is not more than 0.01 mm, otherwise it will make the seal tight.
Mechanical seal spring compression must meet the installation requirements of more than or shortage situation cannot occur, the error is less than 2 mm. Spring mechanical seal if too long, will make the increase of friction caused by wear, spring is too short will cause the pressure of less than the seal failure.
Two, Mechanical seals Disassembly
Mechanical seal removing carefully, using violent means such as hammer etc. are not allowed, in order to avoid the destruction of the sealing element. Mechanical seals can be used by removing the hook, pull out the driving seat gap sealing device, the sealing device if there is dirt, it should go next step after the demolition to cleaning and maintenance.
If the mechanical seals are used simultaneously in the two ends of the pump body, to take care of each other in the disassembly and assembly.
Mechanical seals in operation after the cover if there is loose, to replace the static ring parts as soon as possible, and not to tighten, otherwise it will lead to friction because the trajectory change, leading to the contact surface of the seal is damaged.
