The compression of the mechanical seal spring must be carried out according to the regulations, and the phenomenon of too large or too small is not allowed. The mechanical seal requires error±2.00 mm, too large will increase the specific pressure of the section and accelerate the wear of the section. Too small will result in insufficient specific pressure and cannot play a sealing role. After the spring is installed, it must move flexibly in the spring seat. When using a single spring, pay attention to the direction of rotation of the spring. The direction of rotation of the spring should be opposite to the direction of rotation of the shaft.

After the moving ring is installed, it must keep moving flexibly. After pressing the moving ring to the spring, it should be able to spring back automatically. Put the static ring sealing ring on the back of the static ring first, and then put it into the sealing end cover. Pay attention to protect the section of the static ring, ensure the perpendicularity between the section of the static ring and the center line of the end cover, and align the anti-rotation groove on the back of the static ring with the anti-rotation pin, but do not make them touch each other.

It is absolutely not allowed to directly beat the mechanical seal components during the installation process. When knocking is required, special objects must be used for knocking to prevent damage to the sealing components. All sealing rings should be coated with soapy water and other lubricants during assembly to avoid damage during assembly apron.
