??Rubber seals surface factors

??Rubber seals to prevent fluid or solid particles between the surface and prevent leakage from adjacent binding material or foreign matter such as dust and water intrusion and other parts inside the machine equipment parts.

??Under normal operating pressure equipment, rubber seals occurs at the surface exceeds the permissible level of leakage leakage, rubber seals will not only cause loss of media. Continue to leak device media will make the hard seal material destruction, conventional rubber seal sealing surface is flat and smooth, but to be absolutely no leakage is very difficult in the medium with pressure situations. Rubber seals at a predetermined pressure value, if the outlet end invisible, it can not find the leak, sealing performance is considered acceptable.

??Generally caused the seal leakage is dirt impurities fall onto the surface of the rubber seal, will stay sealed mat surface caused by the gap, thereby seal leakage. Methods to eliminate this failure to clear the drop rubber seal surface dirt and impurities.

??Another case is the rubber seal surface damage. Sealing surface damage caused Lord is bad rubber seal materials. Hardness is not enough, lack of flexibility, causing the surface of the rubber seals cracks and other wear scar, resulting in sealing performance.

??Another reason for the rubber seal leakage due to improper assembly or rubber seal wrong size. During assembly the rubber seal and the junction translucency phenomenon, or rubber seals sealing against too broad. Remedy is to check to check the rubber seals the gap size and uniformity, appropriate to reduce the width of the sealing surface to achieve an effective seal according to drawings.
