Air Shutoff - Test
要确保空气关断阀在发动机吸入气体烟雾时始终闭合，请在每次更换机油时进行测试。 测试失败表明到阀体接口和/或轴承系统的隔板中有磨损。
- 将发动机置于低怠速。 确保常规用于该应用的风扇、动力输出装置等所有辅助装置在使用中。
- 手动启动空气关断。 在电子操作员空气关断中，使用来自蓄电池的适用电源或跨接电缆将空气关断电磁阀通电。 确保电磁阀仅接收瞬时信号，以防过热。 对于某些危险位置单元，在液压操作员空气关断中，通过拉下紧急制动手柄启动。
- 确保空气关断已启动且发动机完全停机。
注: 由于各应用的附加负载和惯性不同，无法确定故障的持续时间。 但是，如果发动机卡住或试图继续运行，这些症状表明可能有磨损部件需要更换。

某些情况下，启动空气关断阀可能导致机油通过轴密封件泄漏。 在发动机负载运转时反复启动空气关断阀会导致涡轮增压器机械性损坏并减少涡轮增压器使用寿命。 |
