摘要： There is disclosed apparatus and method for determining pumping head requirements for an operating pumping system by subtracting a desired delivery head or pressure from an actual head. The difference represents overpressure, and this overpressure is subtracted from a measured pump total dynamic head to establish the pumping head requirement of the system. The pumping head requirement data is recorded together with other data indicating a measured fluid flow rate. The data so recorded is in a form for plotting a system head curve. Once the system head curve is available it is possible to modify the supply system so as to avoid pumping at a pressure in excess of that which may be required for any given flow rate condition. Such avoidance of overpressure pumping produces an energy saving in the operation of the pumping system.

摘要： A flushing station for a ring-pipe or series-pipe system, comprises a cold water port for connecting a cold-water pipe, a hot water port for connecting a hot water pipe, and a waste water port, wherein the cold-water port and the hot water port are fluidicly coupled to the waste water port. The cold-water port, the hot water port and the waste water port are assigned to a bottom side of the flushing station.

摘要： A liquid distribution system having at least one liquid conduit extending from a liquid source to a liquid tap and a method for substantially retaining the temperature of a liquid in the liquid distribution system. When a tapping operation is finished, the liquid is evacuated from the liquid conduit, and a gas is brought into the liquid conduit in order to replace the liquid therein and cause the liquid to flow backwards to the liquid source. When liquid is to be tapped from the liquid tap, the gas is evacuated from the liquid conduit.
