Description
Изобретение относитс к области измерени угловой скорости вращени рабочих элементов объемных пневThe invention relates to the field of measuring the angular velocity of rotation of the working elements of the volume pneu
MOf OTOpOB,MOF OTOpOB,
Цель изобретени - снижение трудоемкости измерени и затрат путем уменьшени номенклатуры измерительных приборов.The purpose of the invention is to reduce the laboriousness of measurement and costs by reducing the range of measuring instruments.
На чертеже изображена принципиал най схема реализации предлагаемого способа измерени .The drawing shows the principle of implementation of the proposed measurement method.
Схема состоит из средств измерени , . преиЛущесУгвенно выполненных в виде протйчногр пневмодатчика 1, св зьшаёмого линией 2 с полостью 3 выталкивани пневмомотора 4,, имеющего .камеру 5 выхлопа и полость 6 подачи сжатого газа. Рабочий орган 7 св зан кинематически с приводным устройством 8 валом 9, угловую скорость вращени которого измер ют согласно предлагаемому способу, и имеет рабочие камеры 10.The circuit consists of measuring instruments,. PREFERENCES Presently made in the form of an air sensor 1, connected by a line 2 to a cavity 3, pushing out a pneumatic motor 4, having an exhaust chamber 5 and a compressed gas supply cavity 6. The operating member 7 is connected kinematically with a driving device 8 by a shaft 9, the angular velocity of rotation of which is measured according to the proposed method, and has working chambers 10.
Способ реализуетс следующим образом .The method is implemented as follows.
В полоеть 6 подачи пневмомотора 4 подвод т сжатый газ, который, заполн рабочие камеры 10, приводит в движение рабочий орган 7 пневмо05016In Poole 6 supply pneumomotor 4 brings t compressed gas, which, filling the working chamber 10, sets in motion the working body 7 pneumo05016
мотора 4 и через вал 9 приводимое устройство 8, Затем рабочие камеры 10 опорожн ютс в камеру 5 выхлопа, снижа давление сжатого газа до 5 близкого к атмосферному. При дальнейшем движении рабочего органа 7 газ, наход щийс в рабочих камерах 10, после выхлопа поступает в полость 3 выталкивани , Т1ткуда отво- 10 дитс по линии 2 на проточныйmotor 4 and through shaft 9 the driven device 8. Then the working chambers 10 are emptied into the exhaust chamber 5, reducing the pressure of the compressed gas to 5 close to atmospheric. Upon further movement of the working body 7, the gas in the working chambers 10, after exhausting, enters the ejection cavity 3, T1, where it is withdrawn along line 2 to the flow-through
пневмодатчик 1. Показани последнего характеризуют угловую скорость вращени вала 9-.air sensor 1. The readings of the latter characterize the angular velocity of rotation of the shaft 9-.
Предлагаемый способ позвол ет 15 исключить преобразователь угловой скорости вращени вала пневмомотора в пневматический сигнал.The proposed method allows 15 to eliminate the angular rotational speed converter of the pneumatic motor into a pneumatic signal.
Некоторое снижение точнос-ти измер емого параметра в сравнении с известным способом вполне допустимо дл определенного класса задач, например, при использовании ченного сигнала в качестве сигнала обратной св зи в системах автоматического управлени пневмоприводом. Кроме того, снижение точности измерени непроисходит в системах приводов с нагрузкой, имеющей посто нные параметры.Some decrease in the accuracy of the measured parameter in comparison with the known method is quite acceptable for a certain class of problems, for example, when using a signal as a feedback signal in automatic control systems of a pneumatic actuator. In addition, a decrease in measurement accuracy does not occur in drive systems with a load that has constant parameters.
