Abstract

FIELD: sanitary engineering. SUBSTANCE: proposed is load redundancy (possibility to increase capacity) of the pump plants at the expense of increased frequency of rotation by using the current frequency step-up converter. On failure of a pump, revolution speed of pumps remained in operation is increased in such a manner to keep the plant capacity at the same level. On repairing the failed pump, speed of revolution comes back to the rated value. EFFECT: higher reliability. 1 dwg

Изобретение относится к области санитарной техники и может быть использовано в насосных станциях с центробежными насосами. Задачей изобретения является повышение надежности насосных станций без увеличения числа резервных насосов. Предлагается использовать нагрузочное резервирование (возможность повышения производительности) насосных агрегатов за счет повышения частоты их вращения путем применения повышающего преобразователя частоты тока. После отказа насоса скорость вращения агрегатов оставшихся работоспособными, повышают таким образом, чтобы производительность станции осталась на требуемом уровне. После восстановления отказавшего насоса - скорость вращения возвращают к номинальному значению. Таким образом обеспечивается требуемая надежности насосной станции без увеличения числа установленных насосных агрегатов. Кроме того увеличивается способность насосной станции работать при пиковых сверхрасчетных нагрузках, при том же количестве рабочих агрегатов.The invention relates to the field of sanitary engineering and can be used in pumping stations with centrifugal pumps. The objective of the invention is to increase the reliability of pumping stations without increasing the number of standby pumps. It is proposed to use load redundancy (the possibility of increasing productivity) of pumping units by increasing their rotation frequency by using a step-up current frequency converter. After a pump failure, the speed of rotation of the units remaining operable is increased so that the productivity of the station remains at the required level. After restoration of the failed pump, the rotation speed is returned to the nominal value. This ensures the required reliability of the pumping station without increasing the number of installed pumping units. In addition, the ability of the pumping station to work at peak over-calculated loads increases, with the same number of working units.
