Brake Accumulator - Test and Charge

Usage:

797F LAJ

------ WARNING! ------

蓄能器充气不当会招致人员伤亡。

干燥氮气是唯一被认可用作蓄能器充气的气体。 用氧气对蓄能器充气会引起爆炸。 如果用的氮气罐配上符合 CGA 压缩气体协会(Compressed Gas Association)标准公司的580号 接头,就不会产生危险。

购买氮气时,确保氮气罐上配有 CGA 580号 接头。 不要用颜色标记,或其它方法来 认定氮气和氧气罐之间的区别。

绝对不能用一个接头,把氮气充气组合连到氮气,氧气及其它各种气体罐公用的出口阀上。 确保使用的是干燥的氮气(纯度99.8 %)


------ WARNING! ------

机器突然动作或在压力下放油,可能对机器上或机器附近的人员造成严重伤害。

为避免可能造成的伤害,在测试和调整液压系统之前,遵照以下程序:

简介

制动系统蓄能器安装在机器左侧机架上纵梁之间。

蓄能器充注步骤

  1. 请参阅专门说明书, REHS5464, "蓄能器排放和充压步骤"。

翻新蓄能器的充注压力


注意

在进行检验、保养、测试、调整及维修产品期间,必须小心以确保装好排放出的油液。 在打开任何舱室或解体任何储有液体的部件之前,要准备好合适的容器收集液体。

有关收集和盛接 Cat 产品上油液的适用工具和用品,请参阅专门出版物, NENG2500, "代理商维修工具目录"。

按照当地法规和要求处置所有液体。


蓄能器翻新后,必须排出蓄能器上部腔室中的空气。 翻新蓄能器之后,在蓄能器的氮气室内加入大约 0.9 L (1 qt) 的 SAE 10W 液压油。 这些油将用来协助排除蓄能器氮气室内的空气。 这些液压油还能够润滑蓄能器中活塞的顶部密封件。

将翻新的蓄能器安装到机器上。 要充注翻新的蓄能器,请参阅专门说明书, REHS5464, "蓄能器排放和充压步骤"。
