Abstract

Дублированный электронасосный агрегат, содержащий составной из двух частей корпус, внешняя часть которого снабжена входным и выходным патрубками и сквозной расточкой, ось которой перпендикулярна осям патрубков, а внутренняя часть которого имеет вид кругового цилиндра с наружным диаметром, равным диаметру сквозной расточки внешней части корпуса, фиксатор взаимного положения частей корпуса, установленные в расточках внутренней части корпуса с ее противоположных концов два центробежных электронасоса, входные полости которых сообщены с входным патрубком через аксиальную полость в перемычке между расточками внутренней части корпуса и радиальное отверстие во внутренней части корпуса, соосное входному патрубку, размещенный в Т-образном канале перемычки между двумя расточками внутренней части корпуса двусторонний обратный клапан, при этом выходная полость каждого электронасоса сообщена с соответствующим отверстием сквозной полости Т-образного канала через переводную канавку на внутренней части корпуса, а глухая полость Т-образного канала сообщена с выходным патрубком, отличающийся тем, что на внутренней поверхности входного патрубка со стороны сквозной расточки внешней части корпуса выполнена расточка с диаметром, равным диаметру радиального отверстия, в стенке радиального отверстия выполнена проточка, в которой установлено пружинное стопорное кольцо, а фиксатор взаимного положения частей корпуса выполнен в виде втулки с наружным диаметром, равным диаметру радиального отверстия, размещенной в расточке входного патрубка и радиальном отверстии между торцевой стенкой расточки и торцом пружинногоA duplicated electric pump assembly containing a two-part body, the outer part of which is equipped with inlet and outlet nozzles and a through bore, the axis of which is perpendicular to the axes of the nozzles, and the inner part of which has the form of a circular cylinder with an outer diameter equal to the diameter of the through bore of the outer part of the housing, a latch the relative position of the parts of the housing, installed in the bores of the internal part of the housing from its opposite ends are two centrifugal electric pumps, the input cavities of which are communicated the inlet pipe through the axial cavity in the jumper between the bores of the inner part of the casing and the radial hole in the inner part of the casing, coaxial to the inlet pipe located in the T-shaped channel of the jumper between the two bores of the inner part of the casing is a two-way check valve, while the outlet cavity of each electric pump is in communication with the corresponding the hole of the through cavity of the T-shaped channel through the transfer groove on the inner part of the housing, and the blind cavity of the T-shaped channel is in communication with the outlet pipe ohm, characterized in that on the inner surface of the inlet pipe from the side of the through bore of the outer part of the housing, a bore is made with a diameter equal to the diameter of the radial hole, a groove is made in the wall of the radial hole, in which a snap ring is installed, and the latch of the relative position of the housing parts is made in in the form of a sleeve with an outer diameter equal to the diameter of the radial hole located in the bore of the inlet pipe and the radial hole between the end wall of the bore and the end face of the spring

Claims

A duplicated electric pump assembly containing a two-part body, the outer part of which is equipped with inlet and outlet nozzles and a through bore, the axis of which is perpendicular to the axes of the nozzles, and the inner part of which has the form of a circular cylinder with an outer diameter equal to the diameter of the through bore of the outer part of the housing, a latch the relative position of the parts of the housing, installed in the bores of the internal part of the housing from its opposite ends are two centrifugal electric pumps, the input cavities of which are communicated the inlet pipe through the axial cavity in the jumper between the bores of the inner part of the casing and the radial hole in the inner part of the casing, coaxial to the inlet pipe located in the T-shaped channel of the jumper between the two bores of the inner part of the casing is a two-way check valve, while the outlet cavity of each electric pump is in communication with the corresponding the hole of the through cavity of the T-shaped channel through the transfer groove on the inner part of the housing, and the blind cavity of the T-shaped channel is in communication with the outlet pipe ohm, characterized in that on the inner surface of the inlet pipe from the side of the through bore of the outer part of the housing, a bore is made with a diameter equal to the diameter of the radial hole, a groove is made in the wall of the radial hole, in which a snap ring is installed, and the latch of the relative position of the housing parts is made in in the form of a sleeve with an outer diameter equal to the diameter of the radial hole located in the bore of the inlet pipe and the radial hole between the end wall of the bore and the end face of the spring the retaining ring, wherein the cavity is formed with an axial cross section, covering a cross-section as the sleeve, and the circlip.
