FW Murphy LR857 Lube Level Regulator
LR857 Lube Level Regulator

 

Murphy LR857润滑油油位调节器保持发动机、泵或压缩机的曲轴箱油位。调整到正确的运行油位后,LR857将在使用时补充机油。如果供油中断且设备继续用油,一个完整的低液位开关将报警和/或关闭设备。LR857保持任何尺寸发动机的机油油位,但建议用于需要三线速动开关的中小型应用和安装。随着曲轴箱油位下降,LR857浮子也会下降并打开指形阀?。这允许机油从供油箱流过LR857进入曲轴箱。当曲轴箱中达到适当的油位时,LR857浮子上升,导致拇指阀关闭进一步的油流。简单和独特的拇指阀是无堵塞的,并提供了一个积极的,无泄漏的密封。通过1/8英寸(3 mm)节流孔的流量对于允许通过LR857重新加注曲轴箱非常重要。 FW Murphy LR857 Lube Level Regulator maintains the crankcase oil level of an engine, pump or compressor. Adjusted to the correct running oil level, the LR857 will replenish oil as it is used. An integral, low-level switch will alarm and/or shut down the equipment, if supply oil is lost and the equipment continues to use oil. The LR857 maintains oil level on any size engine but is recommended for small- to medium-volume applications and installations that require a three-wire, snap-action switch. As crankcase oil level drops, the LR857 float also drops and opens the Thumb-Valve?. This allows oil to flow from the supply tank through the LR857 and into the crankcase. When proper level is attained in the crankcase, the LR857 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. Flow rate through the 1/8 inch (3 mm) orifice is significant to allow crankcase refill through the LR857.
