Изобретение относитс к области измерени параметров движени и может быть использовано при измерении распределени скоростей преимущественно вращательного движени жидкости.The invention relates to the field of measurement of motion parameters and can be used to measure the distribution of velocities, mainly the rotational motion of a fluid.
Известное устройство дл измерени скорости слоев жидкости, содержащее несколько гидрометрических вертушек, св занных с преобразовател ми , имеет сложную конструкцию.The known device for measuring the velocity of the liquid layers, containing several hydrometric rotators associated with the transducers, has a complex structure.
Дл упрощени конструкции устройства в нем гидрометрические вертущки выполнены в виде коаксиально расположенных многолопастных измерительных рамок, кажда из которых св зана с преобразователем скорости вращени в электрический сигнал.To simplify the design of the device, the hydrometric jacks are made in the form of coaxially arranged multi-blade measuring frames, each of which is associated with a converter of rotational speed into an electrical signal.
На чертеже представлена схема предлагаемого устройства.The drawing shows a diagram of the proposed device.
Устройство содержит многололастные рамки 1, помещенные в сосуд с исследуемой жидкостью 2. Рамки 1 насажены на соосные полые валы 3, каждый из которых на свободном конце имеет кодирующий диск 4 дл измерени частоты вращени данной рамки с помощью датчика 5 (например, индуктивного), подключаемого к схеме измерени частоты. Крышка 6 экранирует торцовые поверхности рамок и валы от попадани капель жидкости.The device contains multi-flanged frames 1 placed in a vessel with the liquid under study 2. Frames 1 are mounted on coaxial hollow shafts 3, each of which has a coding disk 4 at the free end for measuring the frequency of rotation of this frame using a sensor 5 (for example, inductive) connected to the frequency measurement circuit. The cover 6 shields the end surfaces of the frames and the shafts against the ingress of liquid droplets.
Число лопастей, размещаемых в каждой рамке, существенного вли ни на точность измерени не оказывает, но дл облегчени балансировки их число должно быть больше трех. Профиль лопастей близок по форме к чечевицеобразному, так что лопасть наибольшей щирины повернута перпендикул рно линейной скорости вращени жидкости. Частота вращени каждой измерительной рамки пропорциональна угловой скорости вращени сло жидкости, сцепленного с ее лопаст ми. Поэтому по соотношению частот, фиксируемых частотомерами, можно однозначно измерить распределение скоростей (поле скоростей ) в каждый момент времени.The number of blades placed in each frame does not significantly affect the measurement accuracy, but their number should be more than three to facilitate balancing. The profile of the blades is close in shape to the lenticular shape, so that the blade of the greatest width is perpendicular to the linear velocity of rotation of the fluid. The frequency of rotation of each measuring frame is proportional to the angular velocity of rotation of the layer of fluid coupled to its blades. Therefore, by the ratio of the frequencies recorded by the frequency meters, it is possible to unambiguously measure the distribution of velocities (velocity field) at each moment of time.
