Description

Дл  измерени  скорости пульсирующего потока газа лредлагаетс  устройство, схема которого изображена на чертеже.To measure the velocity of a pulsating gas flow, a device is proposed, the circuit of which is shown in the drawing.

Между отверсти ми 1 н 2 трубки J4, служащими дл  измерени  статического и динамического «апора. и отводами S и 9 к. манометру в носике трубки J4 устанавливаетс  цилиндрическа  вращающа с  пробка 7, имеюща  каналы 3 к 4 а кольцевые камеры 5 и .Between the holes 1 n 2 tubes J4, serving to measure static and dynamic pressure. and taps S and 9 k. A cylindrical rotating plug 7 is installed in the spout of tube J4, the tubes having 3 to 4 channels and annular chambers 5 and.

При совпадении отверстий каналов 3 п 4 вращающейс  пробки 7 с отвер-сти ми 1 и 2 трубки М последн   включаетс  в работу, в лротивнОМ случае трубка Полностью выключена, т. е- имеетс  периодическое включение и выключение -фубки Н.When the holes of the channels 3 and 4 of the rotating tube 7 with the holes 1 and 2 of the tube M coincide, the tube is put into operation, in the opposite case the tube is completely off, i.e. there is a periodical switching on and off of the hook N.

Врем  оборота пробки 7 устанавливаетс  равным периоду пульсаций . В этом случае трубка 14 и св занный с «ей Атанометр будут воспринимать ТОЛЬКО импульсы, отвечающие определенной фазе колебаний скорое™. Врем , в течение которОГо трубка 14 воспринимает импульсы , может быть сделано достаточно малым, и вли ние изменени The turnover time of the plug 7 is set equal to the pulsation period. In this case, the tube 14 and the Atanometer associated with it will ONLY perceive pulses corresponding to a certain phase of the oscillations ™. The time during which the tube 14 senses pulses can be made sufficiently small, and the effect of the change

скорости за этот промежуток времени будет сведено к минимуму.speeds for this period will be minimized.

Дл  замера пульсирующего потока со всех сторо-н измерительной трубки М наружный корпус этой трубки имеет зубчатку, поворот которой осуществл етс  винтом 12, св занным с шестерней 13. Угол поворота винта 12 фиксируетс  указателем 15.To measure the pulsating flow from all sides of the measuring tube M, the outer body of this tube has a gear, which is rotated by a screw 12 connected to gear 13. The rotation angle of the screw 12 is fixed by the pointer 15.

По достаточному числу измерений , соответствующих различным фазам, устанавливаетс  среднее по времени значение скорости.A sufficient number of measurements corresponding to different phases is used to establish the time average of the speed.

Пробка 7 приводитс  в движение электродвигателем 11.The plug 7 is driven by the motor 11.

Число оборотов фиксируетс  счетчиком 16.The speed is recorded by a counter 16.
