1. Installation Notes

 a. the installation to be very careful to avoid bias arising from the installation, (1) the gland coupling alignment should be carried out after the bolts should be evenly supported to prevent the gland face skewed, with a feeler points , the error is not greater than 0.05 mm. (2) Check the gland and the shaft or sleeve diameter with the gap (ie concentric), four weeks should be uniform, with a feeler points tolerance no more than 0.01 mm.

 b. the amount of compression according to the provisions of the spring, allowed the phenomenon is too large or too small to require error 2.00 mm. Than the pressure may increase the end, the other face wear rate. Too small will cause less than the pressure seal and can not play a role.

 c. ring installed in the shaft after the beard to ensure that mobile and flexible, the pressure to the ring after the spring should be able to automatically bounces back.

 2. disassembly Note

 a. When the demolition of the mechanical seal carefully, non-use of hand-hammer and flat blade, so as not to damage the sealing elements. To do a pair of wire hook, stretching in the direction of self-financing gap in the drive seat, the seal out. If the scale demolition of no less than should be cleaned before demolition.

 b. If the pump mechanical seal both ends, in the assembly, the demolition process to take care of each other, to prevent the other.

 c. mechanical seal on the run-off, where a loose gland seal is moved to the situation, the static rings parts must be replaced, not re-tighten the continued use. Ying move because of the sample, the friction will be a change in the original running track, the contact surface of the seal is very easily damaged.
