In the Hydraulic station system, the control of oil temperature is crucial, which directly affects the performance, reliability and life of the system.
First of all, understanding the factors that affect the increase of oil temperature is the premise of effectively controlling the oil temperature. During the operation of the hydraulic system, the internal friction of components such as hydraulic pumps and hydraulic valves and the friction of oil flowing in the pipeline will generate heat, causing the oil temperature to gradually increase. In addition, the load change of the system, the ambient temperature and the heat dissipation conditions will also affect the oil temperature.
In order to control the oil temperature, you can start from the following aspects. First, choose hydraulic oil reasonably. Different types of hydraulic oil have different thermal stability and viscosity characteristics. Choosing a suitable hydraulic oil can reduce the rate of increase of oil temperature to a certain extent. For example, choosing a hydraulic oil with a higher viscosity index, its viscosity changes less at different temperatures, can ensure the normal operation of the system in a wider temperature range, and reduce the friction loss and heat generation caused by viscosity changes.
The second is to optimize the system design. When designing the Hydraulic station system, the heat dissipation problem should be fully considered. The heat dissipation effect can be enhanced by increasing the area of the radiator and increasing the power of the cooling fan. At the same time, arrange the pipelines reasonably, reduce unnecessary bends and excessively long pipelines, and reduce the pressure loss and heat generation of the oil during the flow process.
The third is to control the workload and running time. Avoid the system running under high load for a long time, arrange the work tasks reasonably, and give the system enough rest time to reduce the rate of increase of the oil temperature.
The fourth is to install temperature sensors and control systems. Monitor the changes in oil temperature in real time. When the oil temperature exceeds the set value, automatically start the heat dissipation device or take other cooling measures. For example, the oil temperature can be reduced by controlling the speed of the cooling fan and adjusting the flow of hydraulic oil.
In addition, keeping the Hydraulic station system clean also helps to control the oil temperature. Impurities and contaminants will increase the friction of the system and cause the oil temperature to rise. Regularly replacing the hydraulic oil and cleaning the filter can effectively remove impurities in the system and ensure the normal operation of the system.
In short, the oil temperature control of the Hydraulic station system requires comprehensive consideration of multiple factors. By rationally selecting hydraulic oil, optimizing system design, controlling workload, installing temperature monitoring and control systems, and keeping the system clean, the oil temperature can be effectively controlled within a reasonable range to ensure the stable operation and long life of the Hydraulic station system.
