System Pressure Release

Usage:

WSF255 XD AE2
注: 如果液力端的排放侧没有安装滚针安全阀或低扭矩阀,则不要操作泵。

执行以下操作,以确保在进行任何保养或脱开任何部件之前,已从系统中释放了压力:

  • 确保发动机没在运行。 将"不准操作"或类似的警告标签贴到点火钥匙开关上。 遵循经过批准的锁定/标定步骤。

  • 确保变速箱处于脱开状态。

  • 确保没有液体输送到连接至泵歧管的吸油管。

  • 确保排放管不被堵塞。 排放管堵塞可能会导致排放系统中压力过高。 压力过高可能会损坏排放系统中的所有部件。

  • 确保排放系统上的安全阀已打开。

  • 检查进口和出口管道上的压力释放表的读数,以确保不存在压力。
