发动机清洁度


注意

从事燃油系统维修时保持极端的清洁度至关重要。 即使微小的微粒都可能会导致发动机或燃油系统故障。


在修理燃油系统前,为了清除灰尘和松散碎屑,应使用高压水系统清洗整个发动机。 确保不要将高压水直接冲洗在喷油器的密封件上。

环境

使用正向加压的维修区域以确保部件不会受到悬浮在空气中的污垢和碎屑的污染。 当从系统拆下部件时,必须立即使用正确、清洁的密封塞密封暴露的燃油连接。 只有在重新连接部件时,才能取下密封塞。 不得重复使用密封塞。 使用后,立即废弃密封塞。 请联系最近的 Caterpillar 代理商,以获取适当的密封塞。

新部件

更换燃油管时,不得弯曲或扭结新管。 管的内部损坏可能导致金属微粒被吸入燃油中。

所有新的燃油滤清器、燃油管、管组件和部件都附带各自的密封塞。 只有在安装新零件时,才能取下密封塞。 如果新部件不附带密封塞,则不应使用该部件。
技师必须穿戴适当的橡胶手套。 修理完成后应立即处置橡胶手套,以免污染系统。

加油

在向柴油箱加油时,加油泵和燃油箱盖组件必须清洁且无灰尘和碎屑。 只有在环境状况不受到灰尘、风、雨的干扰时才能加油。 仅使用无污染、符合操作和保养手册, "油液建议"燃油技术规格中的技术规格的燃油。
