How can we ensure that the mechanical seal installation quality of it

The so-called mechanical seal is actually a rotating machinery oil seal device, it is in a pair or more than the vertical axis of rotation of the end surface of the fluid pressure and compensation mechanism of elastic (or magnetic) role and the auxiliary seal with the cooperation, Thereby preventing the fluid from leaking. So its installation quality requirements are very high, in the installation process requires a series of precautions,
1, the equipment shaft radial runout should be ≤ 0.04 mm, the axial movement is not allowed to more than 0.1 mm;
2, the sealing parts of the device should be installed to keep clean, sealed parts should be cleaned, sealed face intact, to prevent impurities and dust into the sealing area;
3, in the installation process is strictly prohibited bumps, beating, so as not to pay the mechanical seal friction failure and seal failure;
4, when installed in contact with the sealing surface should be coated with a layer of clean mechanical oil, so that can be successfully installed;
5, the installation static ring gland, tighten the screws must be uniform force to ensure that the static ring face and the axis of the vertical line requirements;
6, after installation to promote moving ring by hand, can move the ring on the axis of flexible movement, and a certain flexibility;
7, after the installation of hand drive shaft, the shaft should be no light and heavy feeling;
8, the equipment must be filled with media before operation to prevent dry friction seal failure.
Mechanical seal installed, in order to ensure that the relevant machinery in the subsequent use of the stability of the process.
