Abstract
Изобретение м.б. использовано при автоматизации систем питани пар-к. ровых котлов, дл судовых паросиловых установок. Цель изобретени - расширение диапазона регулировани с одновременным повьвпением надежности работы насоса. Измен ют режим работы питательного насоса, вдздейству на его привод по сигналам, характеризующим уровень барабане и нагрузку котла. Дополнительно дат- .чиком 6 измер ют подачу насоса и при снижении ее до заданного минимального значени прекращают воздействие на привод по сигналам, характеризующим уровень воды в барабане, измер емый датчиком 2, и нагрузку котла, измер емую датчиком 3, в сторону снижени подачи до момента превышени подачей насоса заданного минимального значени . При превышении подачи насоса воды вьше заданного минимального значени возобновл ют это воздействие . Способ позвол ет регулировать подачу питательной воды как по основным регулируемым параметрам, так и на режиме с минимальной заданг- ной заранее величиной подачи. Это позвол ет использовать в качестве привода паровую турбину. 1 ил. (О (ЛInvention m. used in the automation of steam-to-power systems. boilers for ship steam power plants. The purpose of the invention is to expand the range of regulation while at the same time increasing the reliability of the pump. The operation mode of the feed pump is changed by acting on its drive according to the signals characterizing the level of the drum and the load of the boiler. Additionally, sensor 6 measures the pump flow and, at lowering it to a predetermined minimum value, stops acting on the drive according to the signals characterizing the water level in the drum, measured by sensor 2, and the load of the boiler, measured by sensor 3, in the direction of reducing the flow to the moment the pump exceeds the specified minimum value. When the water pump exceeds the specified minimum value, this action is resumed. The method allows one to regulate the feed water supply both in terms of the main regulated parameters and in the mode with the minimum amount of feed in advance. This makes it possible to use a steam turbine as a drive. 1 il. (Oh (L
