Heat affects hydraulic systems primarily through its impact on the hydraulic fluid and the system components. When the temperature of the hydraulic fluid increases, it can lead to several issues that affect the performance and longevity of the hydraulic system.
Effect on Hydraulic Fluid: High temperatures can cause the hydraulic fluid to thin out, reducing its viscosity. This thinning can lead to a decrease in the fluid's ability to lubricate moving parts effectively. As a result, there is an increased risk of wear and tear on the system components, such as pumps, valves, and cylinders. Additionally, the reduced viscosity can affect the system's ability to maintain consistent pressure, which is crucial for proper operation.
Effect on System Components: Prolonged exposure to high temperatures can also degrade the seals and hoses in the hydraulic system. The heat can cause these components to become brittle and crack, leading to leaks. This is particularly critical in systems that operate at high temperatures, as mentioned in the reference, where special materials like viton, PTFE, or PFA are required to withstand prolonged use at temperatures up to 200°C. The use of inappropriate materials or exceeding temperature limits can result in rapid degradation of these components, leading to system failure.
Temperature Control Measures: To mitigate the effects of heat on hydraulic systems, effective temperature control measures are essential. The reference mentions the use of a hot plate with automatic temperature control, which maintains the temperature at a preset value. This helps in ensuring that the hydraulic system operates within safe temperature limits. Additionally, the use of a large area water or air-cooled chiller in the hydraulic system helps in reducing the run-time temperature of the hydraulic oil, thereby maintaining its viscosity and protecting the system components.
Safety Considerations: High-temperature fluids in hydraulic systems pose significant safety risks, including scalding and burns. Leaks in such systems can lead to dangerous situations, including the melting or burning of materials they come into contact with. Therefore, it is crucial to use appropriate safety measures and materials that can withstand high temperatures without degrading.
In summary, heat significantly impacts hydraulic systems by affecting the hydraulic fluid's viscosity and the integrity of system components. Effective temperature control and the use of appropriate materials are essential to ensure the safe and efficient operation of hydraulic systems, especially in high-temperature environments.
