When the rubber hose with the pressure of the hydraulic system between 25-8.0MPa is broken, the sticking method can be adopted: wipe the area around the rupture of the hose; One of "oxygen resin" glue, "801" glue or "502"glue (the length of the glue is about 2-3 times the length of the ruptured part); wrap the glued place with tape or canvas strips in a laminated manner 4- 5 layers (each layer should be coated with glue); tie both ends ofthe canvas strip with the wrapping tape into dead knots; it can be used after it has solidified for 15-20 minutes. Transposition method: In the hydraulic system, the rubber hoses of the same oil circuit have the samespecifications, but bear different oil pressures.
Broken hoses are mostly hoses that are subject to high oil pressure. For example, among the two oil pipes with the same specifications on the boom cylinder of W4-60 excavatorand ZL series loader, the oil pipe connected to the large cavity of the boom cylinder always bears the higher oil pressure. According to this, the transposition method can be used: simply stick or tie the broken hose; usethe oil pipes of the large cavity and the small cavity of the boom cylinder interchangeably (that is, use the unbroken oil pipe to withstand high pressure, and use the unbroken oil pipe to withstand high pressure. Broken but simply patched or tied tubing is subject to low pressure).
