(Summary description)The possible failure of the inner layer of high pressure hydraulic hose and its solution

1, the rubber hose within the hard layer, crack: As the rubber products by adding a plasticizer, so flexible plastic tube. Hose in high temperature, high pressure, the hose overheating, plasticizer will overflow. In addition, overheating of the oil through the system in the cylinder, valves or other components, if a greater pressure drop will lead to decomposition of oil, resulting in the hose layer of oxidation and hardening. In this case, you should first check the hydraulic system operating temperature is normal, the valve throttling, the pump suction duct is smooth, etc., in the exclusion of all factors that may lead to oil temperature and oil decomposition after the replacement of the hose. If only the hose under the rupture of the hard rubber and the top of the well maintained, this indicates that the hose rupture at the excessive extrusion, bending too fast or reverse phenomena such as oil heating and speed up oxidation, will cause the plastic hair hard .

2, the hose inner layer of serious deterioration, significant swelling: hose inner layer of serious deterioration, significant swelling due to the use of hydraulic oil over time or oxidized deterioration of the dirt is present in the hydraulic system, the hose by the chemical effect Deterioration, will be found in the oil back to the broken pieces of rubber. If this happens, should check the physical and chemical indicators of hydraulic oil, check the system fluid and hose glue material compatibility and working temperature is in line with standards.
