Hydraulic hose bursting is a very troublesome problem. Since the bursting of the hose will cause hydraulic oil leakage, the subsequent maintenance is time-consuming, laborious and expensive. So what are the common reasons for hydraulic hose bursts?
The use of inferior hydraulic hose
After the original hydraulic hose is damaged, many people choose low-quality hydraulic hsoe that are not up to standard in order to be cheap. The performance and reliability of this hydraulic hose are far inferior to the original ones.
In addition, the withholding process of the metal joints at both ends of the hydraulic hose is poor, and the sealing and reliability cannot be guaranteed. After a period of use, it will save fuel and even leak. Therefore, when replacing hydraulic hoses, you must choose products from regular big brands. Orientflex will serve you wholeheartedly.
The hydraulic system pressure is too high
If the preset pressure of the hydraulic system is too high, it will increase the probability of hose bursting. The method is to test the pressure value generated by the main pump in combination with various actions. If it is confirmed that the pressure value is too large, the pressure of the multi-way valve can be appropriately lowered.
Hydraulic oil temperature is too high
If the hydraulic system of your machine is high temperature, it will also affect the sealing of hydraulic components and cause tube burst leakage; in addition, the high temperature will also expand the hydraulic components, causing the valve core and valve body to be stuck, resulting in local high temperature and tube bursting.
Mix hydraulic oil of different grades
High-viscosity hydraulic oil has poor fluidity, which will cause high pressure locally in the hydraulic system, which is easy to cause hoseline leakage.
Bad operating habits
If the operator operates rudely, the huge shock load will generate instantaneous shock pressure in the hydraulic system, which will cause premature failure of the press joint between the high-pressure oil hose joint and the rubber hose, oil leakage or hose explosion, which greatly shortens the service life of the hydraulic hose. . In addition, rough handling can also affect the durability of other components, resulting in frequent mechanical failures.
The hydraulic hose is corroded
Although most of the current hydraulic hoses have a certain degree of corrosion resistance, after all, long-term exposure of rubber products to diesel will make the colloid fluffy and deteriorate. It will cause certain adverse effects. Try not to let the hose contact gasoline and diesel.
Generally, the rubber will swell and become fluffy when soaked in gasoline and diesel for a long time. Therefore, in normal use, it is necessary to avoid corrosive liquids such as diesel oil from contacting the hose, and the outer surface of the hydraulic hose should be cleaned frequently.
