摘要： A separator system may include a separator for separating a liquid (e.g. an operating liquid received from a liquid ring pump) from a mixture comprising the liquid and another substance; a level indicator coupled to the separator, the level indicator being for indicating a level of the liquid in the separator, the level indicator comprising a tubular member fluidly connected to the separator such that the liquid within the separator may flow from the separator into the tubular member; and a liquid line configured to supply liquid to the separator, the liquid line coupled to the level indicator such that the tubular member is fluidly connected between the liquid line and the separator.

摘要： A system comprising: a suction line; a liquid ring pump coupled to the suction line, the liquid ring pump comprising a chamber and an impeller mounted within the chamber; a non-return valve arranged to permit fluid to flow into the chamber via the suction line and to prevent or oppose fluid flow out of the chamber to the suction line; a gas line coupled to the liquid ring pump such that a gas may flow into the liquid ring pump via the gas line, the gas line coupled to the liquid ring pump between the non-return valve and the chamber; a valve disposed on the gas line; and a controller configured to control the valve.
