Description
(5) ЦЕНТРОБЕЖНЫЙ НАСОС(5) CENTRIFUGAL PUMP
II
Изобретение относитс , к гидромашиностроению и может быть использовано в центробежных насосах.The invention relates to hydraulic engineering and can be used in centrifugal pumps.
Известен центробежный насос, содержащий корпус с неподвижно установленным в нем упругим уплотнительным кольцом и размещенное с осевым зазором относительно последнего рабочее колесо ц.Known centrifugal pump, comprising a housing with a fixedly mounted in it an elastic sealing ring and placed with an axial clearance relative to the last impeller c.
Недостатком известной конструкции вл етс небольшой межремонтный ресурс работы за счет быстрогоизноса уплотнительного кольца.A disadvantage of the known construction is a small service life between repairs due to the rapid wear of the sealing ring.
Цель изобретени - увеличение ресурса работы.The purpose of the invention is to increase the work resource.
Указанна цель достигаетс тем, что уплотнительное кольцо снабжено клиновидной кольцевой, вставкой и имеет дл размещени последней коническую канавку на торцовой поверх .ности, обращенной к рабочему колесу.This goal is achieved in that the sealing ring is provided with a wedge-shaped annular insert and has a conical groove on the end surface facing the impeller to accommodate the latter.
На чертеже изображен центробежный насос, разрез.The drawing shows a centrifugal pump, a slit.
Центробежный насос содержит корпусThe centrifugal pump includes a housing
1с неподвижно установленным в нем j упругим уплотнительным кольцом 2 и размещенное с осевым зазором 3 относительно последнего рабочее колесо1c an elastic sealing ring 2 fixed in it j and an impeller placed with an axial clearance 3 relative to the latter
, причем уплотнительноё кольцо 2 снабжено клиновидной кольцевой вставкой 5 и имеет дл размещени последней коническую канавку 6 на торцовой поверхности 7) обращенной к рабочему , moreover, the sealing ring 2 is provided with a wedge-shaped annular insert 5 and has to accommodate the latter a conical groove 6 on the end surface 7) facing the worker
10 колесу Ц. Центробежный насос содержит также вал 8.10 wheel C. Centrifugal pump also contains the shaft 8.
Устройство работает следующим образом .The device works as follows.
1515
По мере износа уплотнительного кольца 2 и увеличени зазора 3 вал 8 освобождают и перемещают в осевом направлении , при этом рабочее колесоAs the sealing ring 2 wears and the gap 3 increases, the shaft 8 is released and moved in the axial direction, while the impeller
2продвигает клиновидную кольцевую 2 promotes wedge ring
