摘要： A liquid supply module includes one or more sets of bulk liquid containers each supplying a respective reservoir via a liquid supply line. The bulk liquid containers and reservoirs are vented above the highest liquid level in the system. A pump periodically removes a known volume of liquid from a reservoir which is replenished from a bulk liquid container. A sensor detects a liquid/air transition in the liquid supply line to the reservoir indicative of the exhaustion of liquid resupply from the bulk liquid container. An air vent solenoid valve in communication with the reservoir is closed when an empty bulk liquid container is replaced. Normal pump operation siphons liquid out of the bulk container after container replacement. A control system tracks pump iterations and calculates a number of executable iterations remaining before the reservoir runs dry. With a fresh bulk container in place, the air vent solenoid opens the reservoir air vent upon detection of an air/liquid transition allowing liquid to flow by gravity from the bulk container into the reservoir. A bulk liquid container lid sensor indicates whether a bulk liquid container is properly installed in the system. The liquid module is disposable in a sliding drawer, and can include unique mechanical keying means to insure each bulk liquid container fits in only one position in the liquid supply module.

摘要翻译： 液体供应模块包括一组或多组散装液体容器，每一批液体容器均经由液体供应管线供应相应的容器。 散装液体容器和储存器在系统中排出高于最高液位。 泵从周期性地从大容量液体容器补充的储存器中移除已知体积的液体。 传感器检测到液体供应管线中的液体/空气转变，指示储液器指示从大量液体容器中再供应液体的耗尽。 当更换空的大容量液体容器时，与储存器连通的排气阀电磁阀关闭。 容器更换后，正常的泵操作将液体从散装容器中抽出。 控制系统跟踪泵迭代并计算在油藏运行干燥之前剩余的可执行迭代次数。 在新鲜散装容器就位的情况下，当检测到空气/液体转变时，排气螺线管打开储存空气通道，允许液体通过重力从散装容器流入储存器。 散装液体容器盖传感器指示散装液体容器是否适当地安装在系统中。 液体模块在滑动抽屉中是一次性的，并且可以包括独特的机械键控装置，以确保每个散装液体容器仅装配在液体供应模块中的一个位置。
