how does the mechanical seal manufacturer choose the product?
Feb 11, 2018

How does the mechanical seal manufacturer choose the product? Mechanical seals in the sample after the movement, the friction pair of the original running track will be changed, the contact surface sealing is very vulnerable to damage. There are many types of products, and each is widely used in many industries. Now, with the continuous innovation of technology, the replacement of products more and more to meet the needs of people, especially the company's products, performance is constantly promoted. The following is an introduction to the relevant knowledge of the product.

What problems should be paid attention to when installing and disassembling mechanical seals?

1, the installation of precautions

A, to be very careful to avoid installation errors caused by installation

(1) Tighten the gland should be found after the coupling, bolts should be evenly on the support to prevent the gland face deflection, with Feeler check each point, the error is not greater than 0.05 mm.

(2) Check the gland and shaft or sleeve diameter of the matching clearance (that is, concentricity), evenly around, with feeler check each point tolerance is not greater than 0.01 mm.

b, the spring compression should be in accordance with the provisions, not allowed to have too large or too small phenomenon, required 2.00 mm error. The General Assembly increases the end-face pressure, the other speed end face wear. Too small can cause less than pressure and can not play a sealing effect.

C, dynamic ring after the installation of the beard to ensure that the axis of flexible movement, the dynamic ring pressure to spring should be able to automatically bounce back.

2, Demolition Notice

A, in the removal of mechanical seals to be careful, strictly prohibit the use of hammer and flat shovel, so as not to damage the sealing elements. Can do a pair of wire hooks, in the direction of self-financing into the drive seat gap, the sealing device pull out. If the scaling is not removed, should be cleaned and then removed.

b, if both ends of the pump with mechanical seals, in the assembly, demolition process to take care of each other, to prevent the other.

C, the operation of mechanical seals, where the gland is loose to seal the movement of the situation, the static and dynamic ring parts must be replaced, should not be tightened to continue to use.
