Precautions for the installation of hydraulic system mechanical seals

Hydraulic system hydraulic system mechanical seal is actually a rotary mechanical oil seal device, which is the action of the fluid pressure and compensation mechanism elastic force (or magnetic force) on one or more pairs of end faces perpendicular to the rotation axis and the auxiliary seal In cooperation, the fluid leakage prevention is maintained by the combination of the sliding and the relative sliding.

The installation quality requirements are very high and there are a series of precautions during the installation process. Let's take a look at the specific installation precautions following Dalan Hydraulics:

1. The sealing part of the equipment should be kept clean during installation. The sealing parts should be cleaned, the sealing end surface is intact, and impurities and dust are prevented from being brought into the sealing part;

2. A clean layer of mechanical oil should be applied to the surface in contact with the seal during installation so that it can be installed smoothly;

3. It is strictly forbidden to hit or knock during the installation process, so as to avoid the mechanical seal friction and damage and the seal failure;

4. The radial runout of the equipment shaft should be ≤0.04 mm, and the axial yaw force should not be greater than 0.1 mm;

5. When installing the static ring gland, the tightening screw must be evenly stressed to ensure the vertical requirements of the static ring end face and the axial line;

6. After the installation, push the moving ring by hand to make the moving ring move flexibly on the shaft and have certain elasticity;

7. After installation, the rotating shaft and the rotating shaft should be light and heavy.

8. The equipment must be filled with media before operation to prevent dry friction and seal failure.


If you want to ensure the quality of the entire mechanical seal installation and stability during subsequent use, it is recommended that you still find a professional to do the relevant operations.
