Leakage prevention of rubber hose joint
In the hydraulic system, both metal pipe joints and hose joints are prone to leakage
For ferrule type pipe joints, leakage is mostly caused by the loosening of ferrule or the deformation of pipe end face due to large external force or impact force on the pipe
At this time, check whether the ferrule is out of round, whether the cutting edge is damaged, whether the pipe end is intact and the compression degree of ferrule nut, and eliminate the external force of the pipe
For flared pipe joints, most of them leak due to excessive flared, unqualified quality or repeated disassembly, resulting in flared deformation or cracks
At this time, the front end can be cut off and flared again
If the male and female cone top pressure is used for sealing, the leakage is mostly due to the damage of the two conical surfaces
The conical surfaces can be ground with abrasive sand
In some cases, use & ldquo; о& rdquo; Where the O-ring is sealed by the end face or outer diameter
Causes of leakage of high pressure rubber hose joint
There are several reasons for the leakage of high-pressure rubber hose joints: & ldquo; о& rdquo; Leakage caused by aging or deformation of O-ring& ldquo; о& rdquo; The O-ring is not assembled in place, so that the two planes are pressed unevenly or & ldquo; о& rdquo; The O-ring is cut to cause leakage& ldquo; о& rdquo; The O-ring is not compacted and the elastic deformation is insufficient, resulting in leakage& ldquo; о& rdquo; The O-ring stop groove is too deep to cause leakage
For this, it is necessary to re select the & ldquo; with the same outer diameter and thicker section; о& rdquo; The sealing plane with the stop groove can also be cut or ground to reduce the depth of the stop groove and make & ldquo; о& rdquo; The O-ring shall have sufficient elastic deformation (the compression shall generally be between 0
35-0
65mm)
For the leakage at the pipe joint using oil resistant rubber plate, wool felt, mild steel paperboard, combined sealing gasket or sealant, regardless of the material, first check whether the seal is damaged, deformed, aged and too rough, and then take corresponding measures
Installation of high pressure rubber hose joint
(1) The rubber hose shall not be excessively bent or bent at the root when moving or stationary, and shall start bending at least 1
5 times its diameter; (2) When the rubber hose moves to the extreme position, it shall not be pulled too tightly, but shall be relatively loose; (3) Try to avoid torsional deformation of rubber hose; (4) The rubber hose shall be kept away from the heat radiation components as far as possible, and the heat insulation board shall be installed when necessary; (5) External damage of rubber hose shall be avoided, such as long-term friction on the surface of isomorphic components in use; (6) If the rubber hose is excessively deformed due to its own weight, there shall be supporting parts
