Oil seal: precautions for installing skeleton rubber oil seal
2023/10/27
1. First select the number of oil seals to apply.
2. From skeleton sealing to installation. Keep it clean.
Before installation, it is necessary to strengthen the inspection of the skeleton rubber oil seal and measure whether the specifications of each position of the skeleton rubber oil seal match the specifications of the shaft and waveguide. Before installation, please compare the diameter specifications of the shaft with the diameter specifications of the skeleton sealing gasket. The specifications in the cavity should be suitable for the overall diameter and width of the skeleton seal. Inspect the lip of the skeleton seal for damage or deformation, as well as areas where the yellow spring has fallen or rusted. Avoid damaging the frame sealing ring without placing it in the transportation process, where inertial forces and collisions gently compress it and damage its roundness.
4. Prepare machining inspection data for the parts before processing, and measure whether the specifications of the cavity and various parts of the shaft are reasonable, especially the inner rounded corners, and there should be no tilting. The inner holes of the shaft and waveguide must be squeezed. Smooth, with no damage or burrs on the rounded corners. Clean the machining position of the parts. There should be no burrs, crushed stones, iron sand, or other dirt in the installation part (rounded corners) of the shaft to avoid bending the sealing lip of the skeleton. For damaged skeleton rubber oil seals, it is recommended to use angle r for the rounding position.
In terms of operational skills, you can touch it with your hand for a while to see if it is smooth and smooth.
6. Before installing the skeleton rubber oil seal, it is not necessary to prematurely tear open the packaging bag to prevent dust from adhering to the surface of the frame sealing strip and making it work.
Before assembling the machine, the skeleton rubber oil seal should be properly wiped and the middle of the lip should be coated with lithium tungsten disulfide ester and tungsten disulfide to prevent the shaft from suddenly starting to cool, which can cause the skirt to polish and pose a danger. The gap between the lips. Parts should be processed early. Install the frame seal seat for the skeleton rubber oil seal. If you want to build the machine immediately, it is recommended to cover it with a cloth to prevent dust from adhering to the frame seals. The hands or working shells of the lubricating grease must be clean and tidy.
8. The sealing components of the skeleton should be installed flat and not tilted. It is recommended to use steam pressure equipment or bolted working shells. The air pressure does not need to be very high, and the speed must be uniform and slow.
9. For the machine and equipment installed with the skeleton rubber oil seal this time. Please mark it for easy tracking and pay attention to all steps.

Material classification of O-ring
Natural Rubber is made from rubber latex collected from rubber trees and is a polymer of isoprene. It has good wear resistance, high elasticity, tensile strength, and elongation. It is prone to aging in the air, becomes sticky when exposed to heat, expands and dissolves easily in mineral oil or gasoline, and is alkali resistant but not strong acid resistant· It is a raw material for making tape, hose, and rubber shoes, and is suitable for making shock absorbing parts and products used in liquids containing hydrogen peroxide such as automotive brake oil and ethanol.

Complete knowledge of O-ring sealing
The O-ring rubber ring is a circular shape of a circular rubber ring. O-ring is a widely used hydraulic and pneumatic system for sealing. The O-ring has good sealing performance, which can be used for both static and dynamic sealing; Not only can it be used alone, but many basic components of the sealing device can also be combined. It has a wide range of applications, and if the materials are selected correctly, it can meet various media and sports conditions.
