Description
источник 9 света (лампа накаливани с рефлектором), подключенный к аккумул торной батарее IО через выключатель 11 и реостат 12. В цепи питани источника света имеетс контрольный вольтметр 13, Источник света и фотоэлемент закрыты непрозрачными колпаками 14.a light source 9 (incandescent lamp with a reflector) connected to the battery IO through the switch 11 and the resistor 12. In the power supply circuit of the light source there is a control voltmeter 13, the light source and the photocell are closed with opaque caps 14.
Измерительна кювета-труба св зана с объектом испытани трубопроводом 15 и снабжена устройством дл замера давлени манометром 16 и устройством замера температуры - термопарой 17. Контрольна . кювета 2 подсоединена к источнику сжатого воздуха трубопроводом 18.The measuring cuvette-tube is connected to the test object by pipeline 15 and is equipped with a device for measuring pressure with a pressure gauge 16 and a device for measuring temperature — a thermocouple 17. Test. cuvette 2 is connected to a source of compressed air by pipeline 18.
Замер дымности газа производитс путем сравнени силы тока фотоэлемента 7 от пучка световых лучей, прошедшего через контрольную кювету 2 (чистый воздух), и силы тока фотоэлемента 7 от такого же пучка света, ослабленного при его прохождении через измерительную кювету 1 (задымленный газ). В контрольную кювету 2 во врем замера посто нно нагнетаетс чистый воздух, который через щель на торце этой кюветы с большой скоростью на торец измерительной кюветы 1и дальше в атмосферу, эжектиру газ и одновременно предохран стекла от загр знени .Gas smoke is measured by comparing the photocell current 7 from the beam of light rays passing through the control cuvette 2 (clean air) and the current of the photocell 7 from the same light beam weakened as it passes through the measuring cuvette 1 (smoked gas). During the measurement cell 2, during the measurement, clean air is continuously pumped through the slot at the end of this cell at high speed to the end of the measuring cell 1 and further into the atmosphere, ejecting gas and at the same time protecting the glass from contamination.
Предмет изобретени Subject invention
Устройство дл анализа газовых сред оптическими методами, содержащее побудитель расхода, кювету с фланцами, закрытую с торцов оптически прозрачными пластинами, отличающеес тем, ; что, с цельЮ повышени надежности работы, побудитель расхода выполнен в виде щелевых эжекторов, образованных установкой оптически прозрачных пластин с зазором от фланцев.A device for analyzing gaseous media by optical methods, containing a flow booster, a cuvette with flanges, closed at the ends with optically transparent plates, characterized in; that, in order to increase the reliability of operation, the flow booster is made in the form of slot ejectors formed by installing optically transparent plates with a gap from the flanges.
