The methodThe method of selection using rubber O-rings

 

Rubber O-ring hardness of choice is more important. Low hardness, easy to install, but prone to peeling, installation damage, extrusion pressure even explode. High hardness, inconvenient to install.

 

Usually a rubber O-ring hardness 40 ~ 90 IRHD, but in general the use of 70 IRHD is more appropriate for the silicone rubber is the exception, generally use 60 IRHD.

 

Hardness of the rubber O-ring is important, the size of the rubber O-ring is equally important.

 

Rubber O-ring groove dimensions: bottom diameter, width, groove depth and other data. Concluded that O-ring scale, if it is static seal, so it can often be admitted: bottom diameter /1.04 (elongation of 4% accounting) = O-ring inner diameter; deep groove * 1.2 (20% compression ratio calculation) = O-ring diameter; Reflections after tightening O-ring cross section become type swing, groove width is usually about 1.3 times the diameter. Of course, subject to the conditions induction sealing thinking, I can only say that in general it is. There are other dynamic seals, rotary seals, reciprocating seals, axial seal, radial seal, and so on.

 

When supporting many users after the end of the process, even if the device has passed the test, sent to the user after use for some time still have questions presented, usually under the condition, may be formed by improper use, such as the oil temperature is too high so that the seal burned , you can see the cooling system is not operating properly, rod outer wear and leak, you can see whether the debris inside the hydraulic oil filter is not a failure.

 

Purchasing high-quality O-ring seal, and establish a long time partner is necessary. of selection using rubber O-rings
