Contamination During Installation / 安装过程中污染:
Problem: Dirt, debris, or old hydraulic fluid entering the new pump or system during installation can lead to immediate damage or accelerated wear.
Solution: Always work in a clean environment. Flush the hydraulic system thoroughly before installing the new pump and use clean, new hydraulic fluid. Replace all filters.
问题: 在安装过程中进入新泵或系统的灰尘、碎屑或旧液压油会导致立即损坏或加速磨损。
解决方案: 始终在清洁的环境中工作。在安装新泵之前彻底冲洗液压系统，并使用清洁的新液压油。更换所有滤清器。
Maintenance Issues / 维护问题:
Contaminated Hydraulic Fluid / 液压油污染:
Problem: The most common cause of hydraulic pump failure is contaminated fluid, which can abrade internal components.
Solution: Regularly check hydraulic fluid levels and quality. Follow the manufacturer's recommended service intervals for fluid and filter changes. Use only specified, high-quality hydraulic fluid.
问题: 液压泵故障最常见的原因是液压油污染，这会磨损内部组件。
解决方案: 定期检查液压油液位和质量。遵循制造商推荐的流体和过滤器更换保养间隔。仅使用指定的、高质量的液压油。
Overheating / 过热:
Problem: High operating temperatures can degrade hydraulic fluid and seals, leading to reduced efficiency and premature pump failure.
Solution: Ensure the hydraulic system has adequate cooling. Check for blockages in the cooler, proper fan operation, and correct fluid viscosity.
