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 сквозная полость Т-образного канала двустороннего обратного клапана выполнена скрещивающейся с осью наружной поверхности внутренней части корпуса и размещена между выходным патрубком и продольной осью корпуса, между внешней и внутренней частями корпуса установлен фиксатор их взаимного углового положения, а переводные канавки выполнены на наружной поверхности внутренней части корпуса, причем выход каждой переводной канавки в сквозную полость Т-образного канала выполнен с длинной стороны последней.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 the cylinder is made a bore to accommodate one of the electric pumps, and the T-shaped channel of the bilateral check valve is made in the jumper between the two bores, while the through cavity of the T-shaped channel is two of the check valve is made intersecting with the axis of the outer surface of the inner part of the housing and is located between the outlet pipe and the longitudinal axis of the housing, between their outer and inner parts there is a latch for their mutual angular position, and the transfer grooves are made on the outer surface of the inner part of the housing, with the output of each transfer grooves in the through cavity of the T-shaped channel is made on the long side of the latter.

Claims
