Abstract

Изобретение позвол ет повысить надежность и эффективность работы жидкостно-кольцевой машины путем улучшени торцовых уплотнений. Распределительные диски /Д/ с окнами подвода 6 и отвода 7 рабочей среды установлены с возможностью осевого перемещени . Рабочее колесо с лопатками установлено эксцентрично на валу 8, размещенном в подшипниках 21. Устройство осевого перемещени Д 4, 5 выполнено в виде упорных винтов 11, 12, установленных в отверсти х торцовых крышек 2, 3 корпуса 1. В Д и крышках 2, 3 выполнены соосные отверсти 13 - 16, в к-рых размещены блокирующие винты 17. Отверсти 13, 15 в крышках 2, 3 выполнены сквозными, в Д-глухими резьбовыми. Колесо в продольном сечении выполнено составным из элементов 18, 19, каждый из к-рых с наружной стороны имеет полую ось 20. Ось 20 выполнена заодно с колесом, установлена во внутренней обойме подшипника 21 и взаимосв зана с валом 8. Зат гивание винтов 17 в Д обеспечивает необходимый торцовой зазор между колесом 9 и Д, что приводит к снижению утечек рабочей среды. 1 з.п. ф-лы. 3 ил.The invention improves the reliability and performance of a liquid ring machine by improving the mechanical seals. The distribution discs / D / s with the windows of the inlet 6 and the outlet 7 of the working medium are mounted with the possibility of axial movement. The impeller with blades is mounted eccentrically on the shaft 8 placed in the bearings 21. The axial movement device D 4, 5 is made in the form of stop screws 11, 12 installed in the openings of the end covers 2, 3 of the housing 1. coaxial holes 13–16 are made, in which the locking screws 17 are placed. Holes 13, 15 in the covers 2, 3 are made through, in D-blind threaded holes. The wheel in longitudinal section is made up of elements 18, 19, each of which has a hollow axis 20 on the outside. Axis 20 is made integral with the wheel, installed in the inner race of the bearing 21 and interconnected with the shaft 8. D provides the necessary face clearance between the wheel 9 and D, which leads to a reduction in leakage of the working environment. 1 hp f-ly. 3 il.
