(Summary description)Solution to the failure of the inner layer of the high-pressure hose
1. Hard layer in the rubber tube, cracks: Because the plasticizer is added to the rubber product, the plastic tube has elasticity. When the hose is under high temperature and high pressure, the hose will overheat and the plasticizer will overflow. In addition, if the oil passing through the cylinders, valves or other components of the system is overheated, a greater pressure drop will cause the oil to decompose, resulting in oxidation and hardening of the hose layer. In this case, first check whether the working temperature of the hydraulic system is normal, whether the valve is throttled, whether the suction pipe of the pump is smooth, etc. After removing all the factors that may cause the oil temperature to rise and oil decomposition, the hose should be checked. If only the hose under the rupture of the hard rubber and the top of the well are maintained, it means that the hose is ruptured when over-squeezed.
2. The inner layer of the hose is severely deteriorated and obviously swelled: the inner layer of the hose is severely deteriorated. The severe swelling is due to the use of hydraulic oil over time or oxidative deterioration of dirt in the hydraulic system. The hose is chemically deterio The rubber in the oil shattered. If this happens, check the physical and chemical indexes of the hydraulic oil, and check whether the material compatibility and working temperature of the system fluid and hose glue meet the standards.
