Reasons for damage to steel wire braided rubber hoses during equipment operation

The cracking of high-pressure hoses is usually not caused by excessive static pressure, but only by the strength and frequency of the impact of working pressure.
During the operation of construction machinery and equipment, the pressure inside the hydraulic pipeline will suddenly rise or fall from time to time, causing continuous impact on the working pressure of the pipeline, resulting in aggravated damage to the skeleton seal, bubbles and cracks in the rubber hose, and loose water leakage at the pipe joints. So in practical operation, the rotation of the valve seat should not be too violent, it must be gentle.
Due to the complex types, diverse structures, and different usage conditions of rubber hoses, their service life not only depends on quality, but also on correct use and maintenance. Therefore, even if the product has very high quality, if not used and maintained correctly, it can seriously affect its application quality and lifespan, and even lead to the occurrence of malfunctions.
Steel wire braided rubber hoses and hose assemblies require the use of specific materials, otherwise their service life may be reduced or they may fail. The correct length variation of the hose under high pressure (-4% -2%) and the length variation caused by mechanical motion are also important.
The hose assembly should not be used under pressure exceeding the design working pressure (including impact pressure). Under normal circumstances, the medium temperature of the hose assembly should not exceed -40 ℃ -120 ℃, otherwise it will reduce its service life.
During the operation of construction machinery equipment, due to the loss of output power in the hydraulic transmission system, the hydraulic oil is hot. In addition, the harm of uniform external temperature (especially in summer) can greatly increase the oil temperature. The higher the temperature at which hydraulic oil is used, the poorer its ductility, compressive strength, and sealing properties.
In work, when the temperature of the hydraulic transmission system rises too high or too fast, the cause should be immediately identified and eliminated; Corresponding cooling measures should be taken during continuous work in summer. When disassembling and replacing steel wire braided rubber hoses, the length, number of steel wire layers, appearance and specifications of the joints should be effective, and the degree of bending should be minimized as much as possible.
