Description

II

Изобретение относитс  к гидравлическим машинам и может быть использовано в различных област х народного хоз йства.The invention relates to hydraulic machines and can be used in various areas of the national economy.

Известен шиберный насос, содержащий цилиндрический корпус с эксцентрично установленным в нем ротором, соединенным с приводным валом, снабженный впускным и выпускным патрубками, причем в последнем расположен обратный клапан 1.Known gate pump containing a cylindrical body with an eccentric mounted in it a rotor connected to the drive shaft, equipped with inlet and outlet nozzles, and in the latter is a check valve 1.

Недостатком известного насоса  вл етс  износ пластин-шиберов, работающих в услови х трени  скольжени , а также внутренней поверхности цилиндрического корпуса .A disadvantage of the known pump is the wear of plate-slide valves operating in conditions of sliding friction, as well as the inner surface of the cylindrical body.

Цель изобретени  - уменьшение износа.The purpose of the invention is to reduce wear.

Поставлен«а  цель достигаетс  тем, что в роторе выполнена кольцева  полость, в которой установлено упругое водило, имеющее на конце ролик, взаимодействующий с поверхностью кольцевой полости и кинематически св занное с валом.The goal is set by the fact that an annular cavity is made in the rotor, in which an elastic carrier is installed, having a roller at the end that interacts with the surface of the annular cavity and is kinematically connected with the shaft.

На чертеже изображен шиберный насос.The drawing shows a sliding pump.

Насос содержит цилиндрический корпус 1 с эксцентрично установленным в нем ротором 2, соединенным с приводным валом (не показан), снабженный впускным 3 иThe pump includes a cylindrical body 1 with an eccentrically mounted rotor 2 connected to a drive shaft (not shown), equipped with an inlet 3 and

выпускным 4 патрубками, причем в последнем расположен обратный клапан 5. Б роторе 2 выполнена кольцева  полость 6, в которой установлено упругое водило 7, имею щее на конце 8, взаимодействующий с поверхностью кольцевой полости 6 и кинематически св занное с валом. В корпусе 1 установлены щкбер 9 с пружиной 10.exhaust pipe 4, the latter having a check valve 5. The rotor 2 has an annular cavity 6 in which an elastic carrier 7 is installed, having at the end 8, interacting with the surface of the annular cavity 6 and kinematically connected with the shaft. In case 1 there are mounted cable 9 with spring 10.

Насос работает следующим образом.The pump works as follows.

Приводной вал вращает упругое водило 7, ролик 8 которого катит ротор 2, имеющий fQ полость 6, по внутренней полости корпуса 1. Перекачиваема  жидкость заполн ет пространство между внутренней полостью корпуса 1 насоса и кольцевым ротором 2 и па мере качени  кольцевого ротора 2 перегон етс  к выпускному патрубку через клапан 5. Шибер 9 с пружиной 10 не дают возможность жидкости перетекать к впускному патрубку в момент ее нагнетани  в выпускной патрубок.The drive shaft rotates the resilient carrier 7, the roller 8 of which rolls the rotor 2, having fQ cavity 6, through the internal cavity of the housing 1. The pumped liquid fills the space between the internal cavity of the pump housing 1 and the ring rotor 2 and as the ring rotor rolls towards the outlet pipe through the valve 5. The gate 9 with the spring 10 does not allow the liquid to flow to the inlet pipe at the time of its injection into the outlet pipe.

В предлагаемом насосе достигаетс  существенное снижение износа элементов на20 соса за счет качени  кольцевого ротора по внутренней рабочей полости насоса (трение качени ), а также за счет сведени  трени  скольжени  шибера о кольцевой ротордо минимума.In the proposed pump, a significant reduction in wear of the elements of the pump is achieved due to the rolling of the ring rotor along the internal working cavity of the pump (rolling friction), as well as by reducing the sliding sliding friction against the rotary ring to a minimum.
