In the hydraulic system, whether it is a hydraulic fitting, a metal pipe joint, or a hose joint, there are problems that are prone to leakage.
In the hydraulic system, whether it is a hydraulic fitting, a metal pipe joint, or a hose joint, there are problems that are prone to leakage. For card sleeve type pipe fittings, most of the pipeline is subject to a large external force or impact force, which causes the card sleeve to be loose or the pipe end face to deform, causing leakage.
For fittings such as hydraulic transition fittings, leakage may exist. At this time, check whether the ferrule is out of round, whether the cutting edge is defective, whether the pipe end is intact, and the tightness of the ferrule nut. External force of the pipeline. For flared pipe fittings, most of them are leaked due to excessive flaring, substandard quality or multiple disassembly, resulting in deformation or cracking of the flaring. At this time, the front end can be cut off and reflared. If the top pressure of the male and female cones is used for sealing, most of the leakage is due to the damage of the two cone surfaces, and the cone surfaces can be ground with abrasive sand.
Leakage in such fittings of hydraulic transition fittings is likely to be caused by "о" ring not being compacted and insufficient elastic deformation; leakage of "о" ring stop grooves is too deep. In this regard, it is necessary to re-select the "о" ring with the same outer diameter and a thicker cross section. The sealing plane with a groove can also be cut or ground to reduce the depth of the groove and make "о" The ring has sufficient elastic deformation. For leaks at pipe fittings using oil-resistant rubber sheets, wool felt, soft steel cardboard, combined gaskets or sealants, no matter what the material is, first check the seal for damage, deformation, aging and excessive roughness, and then take Appropriate measures.
