Off Highway Engineering - Lubrizol Special Edition (Chinese) - 17

调查取得的重要发现
• 液压问题最常见,在停机成本和维修费用方面 也最高。 • 保修期满后由于劣质润滑油的使用和忽略维护 日程,导致问题增加。 • 液压油是重要的润滑油,更换频率最少。

• 通常,车辆每周工作 43 小时或每年工作 2,250 小时。 • 设备的一般零部件使用了 5.1 年;租赁企业的设 备稍微要新一些。 • 只有 6% 的设备还在保修期内,因此机械故障维 修费用极高。

问题概述
• 90% 的受访者指出,每年每辆车通常会出现一 次足以使部件停止运行的设备问题。 • 平均停机时间刚刚超过 1.5 天,导致每天收益下 降 700 到 800 美元左右。 • 预计每年每辆车因变速器、车桥和液压系统问 题导致的全部维修与停机费用是 5,046 美元。

详细的问题分析
• 液压问题最常见,维修费用最高。 • 88% 的租赁企业受访者和全部受访者中 71% 的 人认为,液压泵低压是非常严重的问题。 • 一般的车队都会遇到液压问题,导致每 10 个月 发生一次严重停机事故。

• 超过一半的受访者都提到车桥 故障、齿轮故障和离合器打滑 问题。 • 44% 的受访者提到离合器故 障,36% 的受访者提到换档 噪音大问题。 • 39% 的受访者遇到车桥油泥积 聚问题。 • 1/4 的受访者提到润滑油水污 染问题。 •总体而言,由来自区域性 OEM 的车辆组成的车队管理 者提到的问题较多,特别提 到与液压问题和油泥积聚相 关的问题。 • 总体而言,由轮式装载机和挖 掘机组成的车队管理者提到的 问题较少,但和其它车队相 比,这类车队管理者认为润滑 油误用问题的严重性要高。
