How to determine the compression of mechanical seal spring
1. The mechanical seal spring compression measurement is directly measured with a caliper. First, measure the spring expansion and contraction in the free state, and then measure the amount after the mechanical seal is installed in place. One reduction is the compression.
2. Cartridge seals don't need to set the compression amount by yourself, because the entire seal is already set when it is installed, and non-containment seals should be measured according to different pump types.
3. The compression amount of the single spring mechanical seal is 50%-70%, about 3~5mm after the seal is compressed,............
4. Generally, it is enough to compress the spring by 1/3~1/2, of course, the calculation method can also be used. This is a little more work.
Here, small springs and bellows are generally about 4mm, which can be slightly larger. Large springs such as UK and 2000 are generally 5mm. Very simple big spring such as 108, we usually adjust it according to the situation, sometimes it is more than 10mm.
