Abstract
Целью изобретени вл етс повышение эффективности разгрузки центробежного компрессора от осевых усилий. Величина осевого усили , действующего на вал 1 центробежного компрессора, регулируетс путем соединени промежуточных камер 8, выполненных в неподвижной втулке 7 в зоне ступенчатых переходов разгрузочного диска 2, закрепленного на валу 1, каналами 9 с полост ми высокого и низкого давлени 4 и 5. Входные и выходные отверсти каналов 9 могут перекрыватьс поворотной заслонкой 10, съемными заглушками или при помощи регулируемого дроссел . 1 з.п. ф-лы, 3 ил.The aim of the invention is to increase the efficiency of unloading a centrifugal compressor from axial forces. The magnitude of the axial force acting on the shaft 1 of a centrifugal compressor is adjusted by connecting intermediate chambers 8, made in a fixed sleeve 7 in the zone of stepped transitions of the discharge disk 2 fixed on shaft 1, channels 9 with cavities of high and low pressure 4 and 5. Inputs and the outlet openings of the channels 9 may be blocked by a rotary valve 10, removable plugs or by means of an adjustable throttle. 1 hp f-ly, 3 ill.
