Description
(54) РЕГУЛЯТОР (54) REGULATOR
Изобретение относитс к системам регулировани подачи топлива в газовые турбины .This invention relates to systems for regulating the supply of fuel to gas turbines.
Известны регул торы подачи топлива в газовые турбины, содержащие центробежный тахометр, соединенный с клапаном перепуск воздуха, установленным в канале с жиклером , подключенным к полости давлени за компрессором, дл управлени сильфоном, кинематически св занным с дозирующей иг- лой.Known regulators for the supply of fuel to gas turbines include a centrifugal tachometer connected to a valve bypassing air installed in a channel with a jet connected to the pressure cavity behind the compressor to control the bellows kinematically connected to the metering needle.
Предлагаемый регул тор отличаетс тем что в канале дл управлени сильфоном установлен корректор с рабочим объемом , разделенным упругим элементом на две полости , одна из которых соединена с полостью давлени за компрессором, а друга - с трубой Вентури дл воздействи на канал управлени с помощью регулирующей иглы, кинематически св занной с упругим элементом .The proposed regulator is characterized in that in the channel for controlling the bellows there is a corrector with a working volume divided by an elastic element into two cavities, one of which is connected to the pressure cavity behind the compressor, and the other to the venturi pipe to act on the control channel with a regulating needle, kinematically associated with the elastic element.
На чертеже изображена схема пpeдлaгaeМОго регул тора.The drawing shows the scheme of the proposed controller.
Он имеет центробежный тахометр 1, соединенный с клапаном 2 перепуска воздуха в канале 3 с жиклером, подключенным к полости давлени за компрессором, дл управлени сильфоном 4. Сильфон кинематически св зан с дозирующей иглой 5, обеспечивающей подачу топлива из канала 6 к двигателю по каналу 7.It has a centrifugal tachometer 1 connected to the air bypass valve 2 in channel 3 with a jet connected to the pressure cavity behind the compressor to control the bellows 4. The bellows is kinematically connected to the metering needle 5 providing fuel supply from channel 6 to the engine through channel 7 .
Рабочий объем корректора 8 разделен подпружиненной мембраной 9 на две полости одна из которых 10 каналом 11 соед11нена с узким сечением трубы Вентури 12, а друга 13 - с полостью давлени за : комппрессором . Подпружиненна мембрана 9 соединена с ругулирующей иглой 14 дл перепуска воэауу-а из канала 3 в атмосферу по каналу 15.The working volume of the corrector 8 is divided into two cavities by the spring-loaded membrane 9, one of which 10 is connected to channel 11 with a narrow section of the Venturi tube 12, and the other 13 to the pressure cavity behind: the compressor. The spring-loaded membrane 9 is connected to a regulating needle 14 for bypassing the air from channel 3 to the atmosphere through channel 15.
Регул тор работает следующим образом.The regulator works as follows.
На режимах запуска и холостого хода в .зависимости от давлени воздуха в канале 3, равного давлению за компрессором, сипь фон 4 устанавливает дозирующую иглу 5 в положение, обеспечивающее потребный рас- ПОДАЧИ ТОПЛИВА В ГАЗОТУРБИННЫЙ ГЕНЕРАТОР СЖАТОГО ВОЗДУХАIn the starting and idling modes, depending on the air pressure in channel 3, equal to the pressure behind the compressor, sypto von 4 sets the dosing needle 5 to a position that provides the required fuel supply to the compressed air generator.
