Causes and Precautions of Automotive Wiring Harness Protection Sleeve Damage

First, there was a burst in the Automotive Wiring Harness Protection Sleeve. Generally, it is not caused by too much static pressure, but related to the severity and frequency of pressure shocks. When the construction machinery is in operation, the oil pressure in the oil pipe will repeatedly rise or fall suddenly, and the oil pipe is subjected to frequent pressure shocks, which will cause foaming and rupture of the Automotive Wiring Harness Protection Sleeve and loosening and leakage of the pipe joint. Therefore, during operation, the valve stem should not be pulled too hard, but must be gentle.

Secondly, the use temperature of stainless steel metal hose oil is too high. When the hydraulic system heats up the oil due to power loss, coupled with the influence of external air temperature, the oil temperature can rise sharply. The higher the temperature of the oil, the more likely the rubber will age, the elasticity will deteriorate, the strength and sealing performance will decrease, and the hose will burst soon. Therefore, in operation, when the temperature rises too high or too fast in the hydraulic system, the cause should be found out in time and eliminated; in summer operation, especially in continuous operation, necessary cooling measures should be taken.
Finally, the selection and installation of Automotive Wiring Harness Protection Sleeve are unreasonable. When replacing a large-diameter Automotive Wiring Harness Protection Sleeve, the length, number of steel wire layers, joint shape and size of the selected Automotive Wiring Harness Protection Sleeve should be reasonable, and the bending degree of the Automotive Wiring Harness Protection Sleeve should be minimized; when tightening the joint nut, Do not Distortion of the Automotive Wiring Harness Protection Sleeve, excessive bending and twisting will greatly reduce the service life of the Automotive Wiring Harness Protection Sleeve; protective measures should be taken for some parts that are prone to friction to prevent the Automotive Wiring Harness Protection Sleeve from bursting due to wear.
