High-pressure steel wire braided hoseOn the premise of ensuring quality, improper use can greatly shorten the service life. In practical work, many high-pressure hoses are damaged due to improper use.

1、 Unreasonable selection and installation of rubber hoses

When replacing the hose, pay attention to the model and size of the hose used. During the process, reduce the bending of the hose and avoid excessive bending. When tightening the joint nut, it is necessary to prevent the hose from twisting during the process. Bending and twisting beyond the limit will reduce the service life of the hose. After installation, protective measures should be taken in areas prone to friction to prevent rubber hose rupture caused by wear and tear.

2、 Affected by frequent and intense pressure shocks

The occurrence of high-pressure steel wire braided rubber hose rupture is usually not related to the static pressure it is subjected to, but mostly related to the severity and frequency of the impact pressure it is subjected to during operation. During the operation of construction machinery, there will be repeated sudden increases or decreases in hydraulic pressure inside the pipe, resulting in frequent pressure impacts on the pipe body, exacerbating the damage to the oil seals of various organizational structures, causing rubber hoses to rupture, and loose joints to leak. Therefore, during operation, the pulling of the valve stem should not be too strong and should be gentle.

3、 The use temperature of the oil is too high

During the operation of construction machinery, the hydraulic system will generate heat in the oil due to energy loss, and then be affected by external temperature. If the heat dissipation measures are not taken properly, the temperature will continue to rise, resulting in poor elasticity and aggravated aging of the rubber hose. Therefore, in the operation, when the temperature rise of the hydraulic system is too high or too fast, the cause should be identified and eliminated in a timely manner. Cooling measures should be taken during continuous operation.

The above are the factors that affect the service life of high-pressure steel wire braided rubber hoses during use. When assembling the hose and joint, attention should be paid to the crimping speed. If the crimping speed is too fast, it is easy to cause damage to the inner rubber and breakage of the steel wire layer, resulting in premature damage to the hose during use.
