发动机的清洁度


注意

运行燃油系统时保持高清洁度非常重要,因为即便是微小粒子也可能会导致发动机或燃油系统出现故障。


在维修燃油系统前,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。 确保高压水不要对准密封喷油器。

环境

如有可能,维修区应保持相对密封,确保组件不受空气中的灰尘和碎屑污染。 当卸下系统中的组件时,应立即使用适当的密封塞密封暴露的燃油接头。 只有组件重新连接时才能卸下密封塞。 密封塞不得重复使用。 密封塞使用后应立即丢弃。 要获取正确的密封圈,请联系离您最近的 Caterpillar 代理商或授权的 Caterpillar 分销商。

新部件

高压管路不可重复使用。 新高压管路只可安装在一个位置。 更换高压管路时,不要弯曲或扭曲新管路。 管道的内部损坏可能会引起金属粒子进入燃油。

所有新燃油滤清器、高压管路、管道组件和部件均附带密封塞。 只有安装新部件时才可卸下这些密封件。 如果新部件不附带密封圈,则不应使用该部件。
技术人员必须穿戴适当的橡胶手套。 维修完成后,应立即丢弃橡胶手套,以免造成系统污染。

加油

为了向柴油油箱加油,加油泵和油箱盖组件必须清洁且无灰尘和碎屑。 只有当外界条件免受灰尘、风和雨水影响时,才可进行加油。 仅使用未受污染且符合操作和保养手册, "油液建议"燃油技术参数中的技术参数的燃油。
