1. Issue: Contamination in Hydraulic System / 问题：液压系统污染
Description / 描述: Leading cause of pump failure. Abrasive particles can damage internal pump components.
Solution / 解决方案: Always use "clean hydraulic fluid" and "replace filters regularly" as per manufacturer's guidelines. Ensure the system is thoroughly flushed before installing a new pump.
2. Issue: Overheating / 问题：过热
Description / 描述: Can be caused by low fluid levels, clogged coolers, or excessive system load. High temperatures degrade seals and fluid viscosity.
Solution / 解决方案: Maintain "correct hydraulic fluid levels", ensure "coolers are clean and functioning", and avoid consistently exceeding the machine's rated capacity.
3. Issue: Cavitation / 问题：气蚀
Description / 描述: Formation and collapse of air bubbles in the fluid, often due to restricted suction lines or low fluid levels. Causes noise and internal damage.
Solution / 解决方案: Ensure "suction lines are clear and unobstructed", maintain "adequate fluid levels", and check for any "air leaks" in the suction side.
4. Issue: Incorrect Installation / 问题：安装不正确
Description / 描述: Misalignment, improper torque on fittings, or damaged seals during installation can lead to leaks or premature failure.
Solution / 解决方案: Follow the "Komatsu service manual precisely" for installation. Use "proper tools", ensure all connections are "clean and correctly torqued", and replace all "seals and O-rings" during installation.
5. Issue: Wear and Tear / 问题：磨损
Description / 描述: Normal operational wear over time. Can manifest as reduced power, slow response, or increased noise.
Solution / 解决方案: Implement a "scheduled preventative maintenance program", including regular fluid analysis and pressure checks. Replace the pump before catastrophic failure occurs if signs of significant wear are detected.
