What are the hazards of heating in the hydraulic system?

The heating of the hydraulic system is our taboo and prevention of important problems, then the hydraulic system heating will produce what harm to the equipment?

The components of the hydraulic system will deteriorate at high temperature, the flexibility will be reduced, the sealing performance will be reduced, and even the sealing failure will increase the leakage.

When the temperature of working fluid increases, the viscosity of working fluid decreases and the leakage of pump increases, resulting in the decrease of the actual flow of the pump.

When the valve core, valve body material is different, the thermal expansion coefficient is not the same, the spool and valve between the thermal expansion caused by the spool stuck, resulting in the concrete pump can not work.

In order to avoid the occurrence of these phenomena, some concrete pump after a certain period of time, had to stop, so that the system cooling, thereby reducing the start-up rate of the concrete pump, affecting the construction schedule.

When the viscosity of the working fluid drops, the lubrication performance of the working fluid is reduced, the wear of the hydraulic component is accelerated, the wear failure of the component is accelerated, and the service life of the component is shortened.
