Why are appropriate hydraulic fluid levels important in a hydraulic system?

Maintaining appropriate hydraulic fluid levels is crucial for ensuring that the system operates efficiently and to prevent cavitation. When the hydraulic fluid levels drop too low, it can result in insufficient fluid to transfer power effectively, which can lead to increased wear and tear on the system components. Additionally, low fluid levels can cause cavitation, a condition where vapor bubbles form in the fluid due to pressure drops. When these bubbles collapse, they can create shock waves that cause damage to the internal components of the hydraulic system. Maintaining the correct fluid level helps to avoid these issues, ensuring smooth operation, optimal performance, and longevity of the hydraulic system.
