Causes of leakage of high pressure hose fitting
Time of issue:
2021-03-12
Causes of leakage of high pressure hose fitting The application of high-pressure hose is very extensive, and it is used in coal, petroleum and other industries. If the joint of the high-pressure hose leaks, it will bring great losses, so it is necessary to prevent the leakage of the high-pressure hose joint. To prevent leakage of high-pressure hose joints, we must first understand the reasons, so that we can achieve purposeful prevention. There are several reasons for the leakage of high-pressure hose fitting: "о" ring is aging or deformed to cause leakage; "о" ring is not assembled in place, so that the two planes are connected with uneven pressure or the "о" ring is cut to cause leakage; The “о”-shaped ring is not compacted, and the elastic deformation is insufficient, causing leakage; the “о”-shaped ring is too deep to cause leakage. In this regard, it is necessary to re-select the "о" ring with the same outer diameter and thicker section, or cut or grind the sealing surface with the spigot groove to reduce the depth of the spigot groove to make the "о" The ring has enough elastic deformation (compression should generally be between 0.35-0.65mm). Hose fitting crimping machine For leaks at pipe fittings using oil-resistant rubber sheet, wool felt, mild steel cardboard, combined sealing gasket or sealant, no matter what material it is, first check whether the seals are damaged, deformed, aging, and rough. , And then take appropriate measures.
