What is the critical maintenance procedure required to prevent cavitation in a hydraulic system of a landfill compactor?

The critical maintenance procedure required to prevent cavitation in a hydraulic system of a landfill compactor is to ensure that the hydraulic fluid reservoir is properly filled with the correct type of hydraulic fluid, and that the fluid is free from contamination, including air and water. Cavitation occurs when the pressure within the hydraulic system drops below the vapor pressure of the hydraulic fluid, causing vapor bubbles to form. These bubbles then collapse violently when they enter a region of higher pressure, creating shock waves that can damage pump components, valves, and cylinders. Maintaining the correct fluid level ensures that the pump has an adequate supply of fluid and prevents air from being drawn into the system. Using the correct type of hydraulic fluid, as specified by the manufacturer, ensures that the fluid has the appropriate viscosity and anti-cavitation properties. Regularly checking and replacing hydraulic fluid filters removes contaminants that can contribute to cavitation. Bleeding the hydraulic system to remove trapped air is also essential. Low fluid levels, incorrect fluid types, and contaminants all contribute to pressure drops that can induce cavitation, so diligent maintenance is key to preventing this damaging phenomenon.
