Abstract

Дублированный электронасосный агрегат, содержащий корпус, снабженный входным и выходным патрубками, установленные в корпусе с его противоположных концов два центробежных электронасоса, входные полости которых сообщены с входным патрубком, а выходная полость каждого электронасоса сообщена с выходным патрубком через переводную канавку и Т-образный канал двустороннего обратного клапана, а также размещенный в сквозной полости Т-образного канала переключающий элемент двустороннего обратного клапана, отличающийся тем, что корпус выполнен составным из двух частей, на внешней части корпуса с входным и выходным патрубками выполнена сквозная расточка, ось которой перпендикулярна осям патрубков, а внутренняя часть корпуса выполнена в виде кругового цилиндра с наружным диаметром, равным диаметру сквозной расточки внешней части корпуса, с каждого торца кругового цилиндра выполнена расточка для размещения одного из электронасосов, а Т-образный канал двустороннего обратного клапана выполнен в перемычке между двумя расточками, при этом переводные канавки выполнены на наружной поверхности внутренней части корпуса, а между внешней и внутренней частями корпуса установлен фиксатор их взаимного углового положения.A duplicated electric pump assembly comprising a housing provided with inlet and outlet nozzles, two centrifugal electric pumps installed in the housing from its opposite ends, the inlet cavities of which are connected to the inlet nozzle, and the outlet cavity of each electric pump is in communication with the outlet nozzle through the transfer groove and the T-shaped channel of the bilateral the check valve, as well as the switching element of the two-way check valve located in the through cavity of the T-shaped channel, characterized in that the housing is made n made up of two parts, a through bore is made on the outer part of the body with inlet and outlet nozzles, the axis of which is perpendicular to the axes of the nozzles, and the inner part of the body is made in the form of a circular cylinder with an outer diameter equal to the diameter of the through bore of the outer part of the body, from each end of the circular of the cylinder, a bore is made to accommodate one of the electric pumps, and the T-channel of the bilateral check valve is made in the jumper between the two bores, while the transfer grooves are made externally the inner surface of the housing, and between the outer and inner housing parts installed retainer their mutual angular position.
