Operational Checks

Usage:

325D L A3R
操作检查可用来查找系统中的泄漏和工作不正常的部件。 连杆运动的速度或马达的扭矩可用来检查油缸、马达和泵的状况。

执行下列操作检查,以便诊断和排除有关机器的液压回路和部件的问题。

  • 测试和调整, "发动机性能 - 测试(发动机转速)"

  • 测试和调整, "在平地上行驶 - 测试"

  • 测试和调整, "在平地上行驶 - 测试(可选测试)"

  • 测试和调整, "机器在斜坡上的沉降 - 检查"

  • 测试和调整, "在平地上的回转速度和回转过量 - 检查"

  • 测试和调整, "在斜坡上的回转速度和回转漂移 - 检查"

  • 测试和调整, "油缸沉降 - 检查(空载铲斗)"

  • 测试和调整, "油缸沉降 - 检查(负载铲斗)"

  • 测试和调整, "油缸速度 - 检查"

操作检查所用的表中列出的技术规范是经计算的平均值。 由于机器配置和发动机转速不同,这些数值也会不同。 表 1 列出了为获得这些规格而使用的机器配置。

参考有关发动机转速规格,请参阅测试和调整, "发动机性能 - 测试(发动机转速)"。
