The Judging Of The Rubber Oil Seal's Merits
NOVEMBER 02, 2022
Qualified products shall meet the following conditions:
1, the end face of the code identification and need to match.
2, smooth surface, no defect, no deformation.
3, with the skeleton of the rubber seal shape, the end face is round, on the glass plate should be fitted with the glass surface, no disturbance phenomenon.
4, no skeleton oil seal outer edge should be correct, the end surface is smooth, with hand to make its deformation, let go back to the original shape.
5, in the entire circumference of the shape of the edge, the thickness should be consistent with the matching pieces when the test, the edge in the matching neck should be closely fit.
6, with spring Rubber oil seal, spring should be no rust, no deformation, and can be more firmly stuck in the spring groove. Take 50*72*12 rubber oil seal as an example. So that the oil seal from the 1m height of the free landing, if each fall 5 times spring off not more than 1 times, then you can think of spring and oil seal with good.
7. When the distributor buys the rubber oil seal in bulk, it can take the sample to do the oil leaching test first, and measure the rate of its quality change. For example, the oil seal with 25th Transformer oil at (70±5) degree of temperature immersion 24h, its mass change rate should be between 3%-5%.
