How should floating oil seals be inspected?
1. The floating oil seal static seal test simulates a situation where the seal ring is filled with oil and the sealing surface is under pressure, observing whether oil leakage or seepage occurs from the sealing surface to determine if the seal is qualified.
2. Floating Oil Seal Working Surface Hardness Test: Test the hardness of the sealing ring working surface to ensure it has sufficient hardness.
3. Floating Oil Seal Air Pressure Test: The air pressure test simulates the actual working environment of the sealing ring, placing it in water while maintaining atmospheric pressure to ensure the floating sliding seal's integrity. The leakage is observed to determine if the sealing surface is qualified. DO1020B sliding seal manufacturer, their atmospheric pressure is three times the actual operating pressure.
4. Dynamic Seal Performance Test and Reliability Life Test of Floating Oil Seals: The dynamic seal performance test and reliability life test of floating oil seals simulate the actual operating conditions of crawler dozer drive sprockets, ensuring pressure on the floating sliding seal surface, with a strengthening ratio of 4-5 times the test operating conditions.
Analysis of the Abolition of Floating Oil Seals
1. Inappropriate float seal design
Because the floating oil seal must be combined with the floating seal seat to form a complete sealing system, the rationality of the floating seal seat design directly affects the proper functioning of the floating oil seal. Refer to the design data provided by the floating oil seal manufacturer or relevant standards for floating oil seals, and process according to specifications. DO1020B sliding seal quote
2、Inappropriate lubricant use
Improper lubricant use can cause floating oil seals to fail prematurely. Choosing the wrong lubricant can lead to rubber rings corroding and aging, losing their elasticity, especially when combined with heat, which exacerbates this issue. Inadequate lubrication and cooling can also result in the burning of the floating seal ring.
Reasons for Oil Leaks in Floating Oil Seals and Improvement Methods
During the installation of the floating oil seal, due to the incorrect installation of the O-ring causing misalignment, the Shanxi DO1020B sliding seal is not properly installed, resulting in uneven pressure on the sealing surface. This leads to the installation gap of the DO1020B sliding seal, ultimately causing oil leakage.
2. Due to the small diameter of the sealed cavity, the compression force of the seal is too low, thereby reducing the pressure on the compressed surface. This can cause gaps in the sealing surface, leading to oil leakage.
3. Due to the seal working continuously in gear oil, the temperature can become extremely high, exceeding 100 degrees. This can easily lead to rubber aging and loss of elasticity, causing damage and oil leakage.
