heating problem of hydraulic oil

Three main problems and solutions of hydraulic systems are the heating of the hydraulic oil, the vibration of the hydraulic system, and the leakage of the hydraulic system.

The heating problems and solutions of hydraulic oil

Due to the different flow rates of the force transmission medium (hydraulic oil) in the flow process, there is a certain internal friction inside the liquid, and there is also friction between the liquid and the inner wall of the pipeline, which all cause the temperature of the hydraulic oil to rise reason.

An increase in temperature will increase internal and external leakage and reduce its mechanical efficiency. At the same time, due to the higher temperature, the hydraulic oil will expand, resulting in increased compressibility, and the control action cannot be transmitted well.

Solution to the problem of heating of hydraulic oil

heating is an inherent feature of the hydraulic system, which cannot be eradicated and can only be reduced as much as possible. Use good quality hydraulic oil, avoid elbows in the layout of hydraulic pipelines, and use high-quality pipelines, pipe adapters, hydraulic valves, etc.

Vibration problem of hydraulic systems

Vibration problems and solutions of hydraulic system

The shock caused by the high-speed flow of hydraulic oil in the pipeline and the shock caused by the opening and closing of the control valve are the reasons for the vibration of the system. Strong vibration can cause errors in system control actions, as well as errors in some of the more sophisticated instruments in the system, leading to system failures.

The solution to the vibration of the hydraulic system

the hydraulic pipeline should be fixed as far as possible to avoid sharp bends. Avoid frequently changing the direction of the liquid flow, and damping measures should be taken when it is unavoidable. The entire hydraulic system should have good vibration damping measures, and at the same time, avoid the impact of external vibration sources on the system.

leakage problem of hydraulic system

The leakage problems and solutions of hydraulic system

Internal leakage refers to the leakage process that occurs inside the system, such as the leakage on both sides of the hydraulic cylinder piston, the leakage between the control valve spool and the valve body, etc. Although the internal leakage will not cause the loss of hydraulic oil, due to the leakage, the established control action may be affected until the system malfunctions.

External leakage refers to the leakage that occurs between the system and the external environment. If hydraulic oil leaks directly into the environment, it will not only affect the working environment of the system, but also cause failures due to insufficient system pressure. The hydraulic oil that leaks into the environment also poses a fire hazard.

The solution to the leakage problem of the hydraulic system

Use better quality hydraulic seals to improve the processing accuracy of the equipment.

This post about three main problems and solutions of hydraulic systems hope more help for your hydraulic systems.
