Description
Изобретение относитс к устройствам дл контрол физико-химических характеристик жидких сред, в частности, к устройствам дл измерени в зкости, и может быть использовано дл контрол и управлени химическими и нефтехимическими процессами .The invention relates to devices for monitoring the physicochemical characteristics of liquid media, in particular, to devices for measuring viscosity, and can be used to monitor and control chemical and petrochemical processes.
Целью изобретени вл етс повышение точности измерени и упрощение конструкции устройства.The aim of the invention is to improve the measurement accuracy and simplify the design of the device.
На чертеже изображена схема предлагаемого устройства.The drawing shows a diagram of the proposed device.
Устройство состоит из побудител расхода 1, посто нных капилл ров 2 и 5, дроссел 3, регулируемого капилл ра 4, дифманомет- ра 6 и исполнительного органа 7 со шкальным устройством 8.The device consists of a flow rate driver 1, fixed capillaries 2 and 5, droplets 3, an adjustable capillary 4, a differential pressure gauge 6, and an actuator 7 with a scale device 8.
Устройство работает следующим образом .The device works as follows.
При изменении в зкости жидкости, протекающей через устройство, возникает перепад давлени , воспринимаемый динамическим нуль-индикатором. Регулирующа схема воздействует через исполнительный орган на регулируемый капилл р, измен его сечение до возобновлени равновеси моста, при котором перепад на дифманометр становитс равным нулю. Значение кинематической в зкости указываетс на шкальном устройстве, жестко св занном с исполнительным органом.When the viscosity of the fluid flowing through the device changes, a pressure differential occurs that is perceived by the dynamic null indicator. The control circuit acts through the actuator on the adjustable capillary, changing its cross section until the equilibrium of the bridge is restored, at which the differential on the differential pressure meter becomes zero. The value of the kinematic viscosity is indicated on a scale device rigidly connected to the executive body.
Экономический эффект от использовани предлагаемого изобретени (в результате уменьшени погрешности измерени от 3 до 1,5%) может быть получен за счет увеличени выпуска продукции с минимальным запасом по качеству.The economic effect of using the present invention (as a result of reducing the measurement error from 3 to 1.5%) can be obtained by increasing output with a minimum quality margin.
