发动机机油压力开关测试是一种发动机机油压力驱动测试和电连续性测试。 这种测试可确定发动机机油压力开关是否出现故障,以及是否需要更换发动机机油压力开关。 使用 1U-5470 发动机压力总成 和 8T-0500 连续性测试仪 进行此测试。

  1. 如果与发动机机油压力开关具有相同发动机机油压力的检修孔未接近发动机机油压力开关,拆下发动机机油压力开关。 在该位置处安装一个三通管。 在三通管一侧安装发动机机油压力开关,并在三通管对侧连接 1U-5470 发动机压力总成 。

    注: 如果有正确接头,此测试也可在带有进气压力的工作台上进行。

  1. 从接线箱上断开发动机机油压力开关。 发动机停机时,检查触点 (2) 和常用触点 (1) 间的连续性。 连续性应是断开的。 然后,检查触点 (3) 和常用触点 (1) 间的连续性。 连续性应是关闭的。

  1. 起动发动机并允许发动机运转。 从发动机起动时开始观察 8T-0500 连续性测试仪 和 1U-5470 发动机压力总成 ,直至发动机已运转。 发动机机油压力开关的发动机机油压力大于其消动压力时,触点 (2) 和常用触点 (1) 间的连续性应关闭。

    发动机机油压力开关的发动机机油压力高于其消动压力时,发动机应开始运转,而起动马达应断开。 发动机机油压力开关的连续性改变时,记录压力表中的读数。 对读数和发动机机油压力开关消动压力的规格进行比较。

  1. 发动机机油压力开关的发动机机油压力高于其指定消动压力时,发动机机油压力开关应关闭触点 (2) 和常用触点 (1) 。 如果发动机机油压力开关未关闭,则发动机机油压力开关出现故障。 更换有故障的开关。
