Description
Изобретение относитс к области компрессоростроепи .This invention relates to the field of compressor construction.
Известны устройства дл регулировани радиального зазора между лопатками рабочего колеса и подвижным коническим воздухозаборником в осевом компрессоре. Предлагаемое устройство отличаетс от известных тем, что в воздухозаборнике установлен датчик , например фотоэлектрический, дл замера радиального зазора и подачи электрического сигнала преобразователю, подключенному к сервомеханизму, кинематически св занному с воздухозаборником.Devices are known for adjusting the radial clearance between the impeller blades and the movable conical air intake in an axial compressor. The proposed device differs from those known in that a sensor, such as a photoelectric sensor, is installed in the air intake to measure the radial clearance and provide an electrical signal to the transducer connected to the servo-mechanism connected kinematically to the air intake.
Такое выполнение устройства позвол ет сохранить радиальный зазор минимальным.Such an embodiment of the device allows the radial clearance to be kept to a minimum.
На чертеже схематично представлено описываемое устройство.The drawing schematically shows the described device.
Рабочее колесо У установлено в коническом подвижном воздухозаборнике 2. В воздухозаборнике установлен также датчик 3 дл замера радиального зазора и подачи электрического сигнала преобразователю 4, подключенному к сервомеханизму 5, кинематически св занному с воздухозаборником.The impeller Y is installed in a conical movable air intake 2. Sensor 3 is also installed in the air inlet to measure the radial clearance and provide an electrical signal to the converter 4 connected to servo-mechanism 5, kinematically connected with the air intake.
