How should the floating oil seal be tested?

2019-11-05 14:19:24
1. The floating seal static seal test simulates whether the sealing surface is filled with oil and the sealing surface is guaranteed to have pressure. Observe whether the sealing surface is leaking or seeping oil to determine whether the seal is qualified.


2. Hardness test of floating oil seal working face: Test the hardness of the working face of the sealing ring to ensure that the working face has sufficient hardness.


3. Floating oil seal pressure test: The air pressure test simulates the actual working environment of the seal ring. Under the condition of ensuring the atmospheric pressure of the floating sliding seal, it is placed in the water to observe whether it leaks to determine whether the sealing surface is qualified. The atmospheric pressure is 3 times the actual use pressure.


4. Dynamic sealing performance test and reliability life test of floating oil seal: dynamic seal performance test and reliability life test of floating oil seal simulate the actual working condition of the track-type bulldozer roller, ensure the pressure of the floating sliding sealing surface, and the strengthening ratio is the experiment. 4-5 times the working condition.
