LM500-TF油位维持计 自动补油器
Murphy LM500-TF Oil Level Maintainer

 

Murphy LM500-TF机油油位保持器包括一个测试功能,通过一次按下测试按钮即可确认浮子和开关均正常工作。LM500系列保持发动机、泵或压缩机的曲轴箱油位。调整到正确的运行油位后,它将在使用时补充机油。如果供油中断且设备继续用油,低液位开关将报警和/或关闭设备。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.
