Description
Изобретение относитс к управлению насосными агрегатами, в частное ти к регулированию режима остановки насосной установки, и может быть использовано в системах водоснабжени и канализации.The invention relates to the control of pumping units, in particular, to the regulation of the stopping mode of a pumping unit, and can be used in water supply and sewage systems.
Целью изобретени вл етс уменьшение гидравлического удара в напор ном водоводе при аварийном обесточи- вании. цепи электропитани приводного электродвигател . IThe aim of the invention is to reduce the water hammer in the pressure conduit during an emergency de-energization. power supply circuits for the drive motor. I
На чертеже схематично изображена насосна установка.The drawing schematically shows the pump installation.
Установка содержит насос 1 с валом 2, напо рные водоводы 3 с клапанами 4, установленный на валу 2 приводной электродвигатель 5 с цепью 6 электропитани , в которой установлен выключатель 7, дополнительный электродвигатель 8, установленный на валу 2 насоса 1, цепь 9 электро064852The installation includes a pump 1 with a shaft 2, direct conduits 3 with valves 4, a drive motor 5 mounted on a shaft 2 with a power supply circuit 6 in which a switch 7 is installed, an additional motor 8 mounted on the shaft 2 of a pump 1, a circuit 9 electro
