Have the PVC Braided Hoses been Maintained Correctly?
Causes of Hydraulic Hose Burst
People who have used excavators have encountered the problem of hydraulic hose bursting. This is a very common and important problem. If it is not handled in time, it may cause bigger problems. Time will delay the construction period. So the best way is to prevent this kind of accident. Next, the manufacturer of the hydraulic hose will analyze the reasons for the burst of the hydraulic hose:
The quality of the hydraulic hose is too low:
There are many reasons why the quality of hydraulic hoses does not meet the standards. For example, if you purchase cheap and inferior products, it may be that the selected specifications do not meet the requirements for use. These two factors make the function of the hydraulic hose have a certain gap in all aspects. Although it can be used, the service life will be greatly shortened, and it is easy to cause problems such as leakage and bursting.
The pressure of the hydraulic system is too high:
In addition to the quality problems of the hydraulic hose itself, there may also be problems of the hydraulic system itself. For some reasons, such as the preset pressure is too high, the pressure on the hose will be too high, which increases the chance of bursting of the hose. If the pressure in the tube is longer than the maximum pressure the hose can withstand, it will cause the hydraulic hose to rupture or even burst. Therefore, without understanding the magnitude of the pressure generated by the system, the preset pressure can be lowered to avoid damage to the hydraulic hose and loss.
The temperature in the hydraulic system is too high:
Excessively high temperature will not only accelerate the aging of the hydraulic hose, but also affect the sealing performance of the hose, causing the oil body in the pipe to leak. This is because the hydraulic hose is a kind of rubber product, which also has the characteristics of thermal expansion and contraction, so too high temperature will cause the hydraulic hose to expand, causing problems such as blockage and jamming of the assembly and valves, which may eventually lead to A tube explosion occurred.
