Causes of bursting of hydraulic pipes of excavators

1. Excessive temperature of the hydraulic system of the excavator equipment will cause the hydraulic oil to heat up, and will also affect the re-closure of the hydraulic components. Moreover, too high temperature will cause the hydraulic components of the equipment to expand and cause the volume to be too large, which will directly cause the valve core and valve body to jam, and thus cause local high temperature to burst the hydraulic pipeline of the excavator.

2. Use mixed hydraulic oil and mix different types of hydraulic oil. Excavators generally use 46# hydraulic oil. If 68# hydraulic oil is accidentally used, which is a commonly used model in the factory parts library, the hydraulic oil will become unstable and cause damage to the components. High viscosity hydraulic oil has poor fluidity, which will cause excessive pressure in the hydraulic system and cause pipeline leakage.

3. The quality of the hydraulic pipe used is too poor. In order to save costs, some people will choose to use hydraulic pipes that do not meet the standards. The performance and reliability of this hydraulic pipeline is far from the original hydraulic pipeline. ...

4. The hydraulic system pressure is too high. This method is mainly used to test the pressure and various actions generated by the main pump. If it is confirmed that the pressure value is too large, the pressure of the multi-way valve can be adjusted appropriately.
