Description
хода по давлению, выходной сигнал которой равен нулю при отсутствии изменени расхода и давлени и при возрастании давлении в пределах действи гидравлического регул тора давлени , когда изменение давлени не влечет изменени расхода. Отклонение производной расхода по давле .. нию от нул приводит к включению определител 4 изменени режима работы, сигнал определител 4, измен ющийс по заданной программе , подаетс на преобразователь Величина этого сигнала пропорционална требуемой скорости вращени рабочего колеса насосной установки 6. Преобразователь 3 формирует сигнгш управлени электроприводом 5. Изобретение позвол ет избежать непроизводительного повышени йавлени в напорной сети, в результате чего снижаетс потребление электроэнергии , увеличиваетс надежность и срок службы напорных трубопроводов.a pressure stroke, the output of which is zero with no change in flow rate and pressure and with increasing pressure within the range of the hydraulic pressure regulator, when the change in pressure does not cause a change in flow. The deviation of the derivative of the flow rate by pressure from zero leads to the inclusion of the determinant 4 changes in the operating mode, the signal of the determinant 4, varying according to a given program, is fed to the converter. The magnitude of this signal is proportional to the required rotational speed of the impeller of the pump unit 6. electric drive 5. The invention allows to avoid unproductive increase of pressure in the pressure network, as a result of which power consumption is reduced, reliable nce and lifetime of pressure pipelines.
