Hydraulic overheat ??? Pahami dulu cara kerjanya !!!

When a excavator experiences hydraulic overheating, it indicates that the hydraulic system is operating at a higher temperature than recommended. Hydraulic overheating can lead to decreased performance, damage to components, and potential system failure if not addressed promptly. Here are some steps you can take to address hydraulic overheat in an excavator:

Stop Operating: If you notice the hydraulic system overheating, the first step is to stop operating the excavator and allow it to cool down. Continuing to operate the machine while it's overheating can exacerbate the issue and potentially cause severe damage.

Check Hydraulic Fluid Level: Inspect the hydraulic fluid level in the reservoir or tank. Ensure that the fluid level is within the recommended range. Low fluid levels can cause increased heat due to inadequate lubrication and cooling.

Inspect Hydraulic Fluid Condition: Check the condition of the hydraulic fluid. If the fluid appears dirty, contaminated, or has a burnt smell, it may need to be replaced. Contaminated fluid can cause increased friction and heat generation within the system.

Clean Heat Exchangers and Coolers: Inspect the heat exchangers, coolers, and radiator for any debris, dirt, or obstructions. Clean them thoroughly using compressed air or water to ensure proper airflow and cooling efficiency.

Check Hydraulic Filters: Inspect the hydraulic filters for any clogs or restrictions. Dirty or clogged filters can impede the flow of fluid and cause increased heat. Replace the filters if necessary.

Inspect Hydraulic Hoses and Connections: Check for any leaks, loose connections, or damaged hydraulic hoses. Leaks can lead to a loss of hydraulic fluid, which affects the system's cooling ability. Repair or replace any damaged components as needed.

Monitor Work Load and Operating Conditions: Be mindful of the workload and operating conditions of the excavator. Continuous heavy loads, high ambient temperatures, or prolonged operation can contribute to hydraulic overheating. Adjusting the workload or taking breaks can help prevent overheating.

Consider Hydraulic Fluid Upgrade: If the excavator frequently experiences overheating issues, consult with the manufacturer or a hydraulic specialist to determine if upgrading to a hydraulic fluid with better temperature tolerance is recommended.
