Boom Kickout Valve - Test and Adjust
动臂限位阀确保动臂不会垂直升高。 当动臂接近垂直时,动臂上的横梁应与柱塞接触。 柱塞将启动动臂限位阀,且绞盘应停止。
- 把机器开到平整水平的地方。 移到远离工作的机器和人员的地方。
- 机器上仅允许留一位操作员 让其他所有人员远离机器或在操作员的视野范围内。
- 将变速箱置于空档位置。
- 接合停车制动器。
- 在低怠速位置运转发动机。
- 缓缓升起动臂。
注: 当动臂接近垂直时,动臂上的横梁应接触柱塞。 柱塞应驱动动臂限位阀,且绞盘应停止转动。
- 如果绞盘不停止,请执行调整步骤。
- 从左吊管机架 (3) 上拆下盖板。
- 松开将阀 (1) 安装到机架的螺栓 (4)。 阀 (1) 应能够通过安装支架上的开槽孔自由移动。
- 调整阀 (1),使尺寸 (A) 为
13 cm (5.1 inch) 。 此为阀 (1) 上的支重轮和柱塞 (2) 之间的距离。 - 拧紧螺栓 (4)。
- 重复测试步骤。 如果绞盘不停止,则将阀
2 mm (0.08 inch) 移至靠近柱塞。 - 重复步骤 5,直到当动臂靠近垂直方向时绞盘停止为止。
