Murphy LM500, LM500-TF oil level maintainers油位维持计
New LM500 Level Maintainer
摩菲LM500-TF油维持计包括一个监测功能，确保浮子和开关的正确操作与一个单一的按测试按钮。LM500系列维持发动机曲轴箱，压缩机或泵的油位,油位过低时自动调整补充油位到机器正常运转需要的油位。 LM500-TF油维持计可以在油位过低时它内部的开关发会出报警信号和/或关闭设备以保证设备的正常运转。The Murphy LM500-TF Oil Level Maintainer includes a test feature that confirms both the float and switch are operating correctly with a single press of the test button. The LM500 series maintains the crankcase oil level of an engine, pump or compressor. Adjusted to the correct running-oil-level, it will replenish oil as it is used. The low-level switch will alarm and/or shutdown the equipment if supply oil is lost and the equipment continues to use oil.

LM500 可在任何尺寸的发动机上保持油位。当曲轴箱油位下降时，LM500 浮子也会下降并打开拇指阀。这样，机油就可以从供油箱流出，流经 LM500 并进入曲轴箱。当曲轴箱达到适当的液位时，LM500 浮子上升，导致拇指阀关闭进一步的油流。简单而独特的拇指阀是无堵塞的，并提供积极、无泄漏的密封。它还支持需要 3 线速动开关的安装。LM500 系列可保持发动机、泵或压缩机的曲轴箱油位。调整到正确的运行油位，它将在使用时补充油。如果供应油丢失并且设备继续使用油，低液位开关将报警和/或关闭设备。LM500 由压铸铝制成，具有清晰的“青蛙眼”高冲击透镜，使操作员无需关闭设备即可查看油位和状况。

The LM500 maintains oil level on any size engine. As crankcase oil level drops, the LM500 float also drops and opens the Thumb-Valve. This allows oil to flow from the supply tank, through the LM500, and into the crankcase. When proper level is achieved in the crankcase, the LM500 float rises, causing the Thumb-Valve to close off further oil flow. The simple and unique Thumb-Valve is non-clogging and provides a positive, leak-free seal. It also supports installations that require a 3-wire, snap-action switch. The LM500 series maintains the crankcase oil level of an engine, pump or compressor. Adjusted to the correct running-oil-level, it will replenish oil as it is used. The low-level switch will alarm and/or shutdown the equipment if supply oil is lost and the equipment continues to use oil. The LM500 is made of die cast aluminum and features a clear "frog eye" high impact lens which allows the operator to view the oil level and condition without shutting down the equipment.
