Изобретение относитс к средства м контрол параметров работы насосной установки в услови х отказа одного или нескольких контрольных датчиков и может быть использовано при проектировании автономных систем транспортировки жидкости, например дл шахтного водоотлива .The invention relates to a means of monitoring the operating parameters of a pumping installation under the conditions of failure of one or several monitoring sensors and can be used in designing autonomous systems for transporting liquids, for example, for mine drainage.
Известно устройство дл автоматического управлени производитель-; ностью нагнетател по сигналу датчиков расхода и давлени с помощью электронного регул тора l.A device for automatic control of the producer is known; by the signal of the flow and pressure sensors using the electronic controller l.
Недостатком известного устройств вл етс недостаточна стабильность регулировани по да1влению.A disadvantage of the known devices is the inadequate stability of the regulation over the time.
Известно устройство дл контрол работы насосной установки, Содержащее установленные на напорном патрубке насоса датчики, подключенные через блоки сравнени к сумматору, и эталонные модели, св занные с блоками сравнени 2.A device for monitoring the operation of a pumping installation is known. It contains sensors installed at the discharge port of the pump, connected through comparison units to the accumulator, and reference models associated with comparison units 2.
Недостатком известного решени вл етс мала надежность в случае выхода из .стро какого-либо датчикаA disadvantage of the known solution is low reliability in the event that any sensor leaves the building.
Цель изобретени - повышение надежности работы.The purpose of the invention is to increase the reliability of work.
Поставленна цель достигаетс -м, что устройство дополнительноThe goal is achieved - the device additionally
