What Are The Nine Major Installation Methods For Mechanical Seals?
Apr 26, 2018

What are the nine major installation methods for mechanical seals?


What are the installation requirements for mechanical seals? Today we have entered the nine major installation steps for mechanical seals!


1. During installation, the surface in contact with the seal should be coated with a layer of clean lubricant so that it can be assembled smoothly.


Recommended lubricants: soapy water, silicone grease, ethylene glycol, or glycerine.


2. The sealing cavity of the equipment should be kept clean during installation. The sealing parts should be cleaned to keep the sealed end face intact and prevent impurities and dust from being carried into the sealed part.

3. It is forbidden to knock and strike in the installation process, so as to avoid damage to the mechanical seal and seal failure;


4. The rotational direction of the equipment shaft shall be ≤ 0.04mm, and the amount of axial turbulence shall not exceed 0.1mm;


5, when installing the static ring gland, tighten the screws must be uniform, to ensure that the end of the static ring and the shaft perpendicular to the seeking;


6. After the installation, pushing the moving ring by hand can make the moving ring move flexibly on the shaft and have certain flexibility;


7. After the installation, the rotating shaft and the rotating shaft should be moved by hand;


8, the device must be filled with media before operation to prevent dry friction and seal failure;


9. For easy crystallization, granular media, when the temperature of the medium is >80°C, appropriate measures should be taken for flushing, filtering and cooling. For various auxiliary devices, refer to the relevant standards for mechanical seals.
