Description

Предлагаемый вискозиметр, основанный на истечении жидкости через винтовой капилл р и предназначенный дл  определени  в зкости не только густых жидкостей, но и крупных взвесей, например целлюлозы в воде, позвол ет определ ть концентрацию целлюлозы в жидких потоках и степень размола целлюлозы в роллах.The proposed viscometer, based on the flow of fluid through a screw capillary and intended to determine the viscosity of not only thick liquids, but also coarse suspensions, such as cellulose in water, allows determining the concentration of cellulose in liquid streams and the degree of grinding of cellulose in rolls.

Устройство и работа вискозиметра по сн етс  чертежом.The design and operation of the viscometer is explained in the drawing.

Залита  в мерный цилиндр 1 жидкость после подн ти  клапана 2 протекает в нижнюю часть прибора через винтовой капилл р 3, помещенный в цилиндре 4.The liquid poured into the measuring cylinder 1 after the valve 2 is raised, flows into the lower part of the device through a screw capillary tube 3 placed in the cylinder 4.

Как известно, чем больше в зкость или концентраци  вещества в жидкости, тем больше внутреннее сопротивление трению, вследствие чего происходит потер  напора и уменьщение скорости выхода жидкости из винтового капилл ра в единицу времени.As is well known, the greater the viscosity or concentration of a substance in a liquid, the greater the internal resistance to friction, as a result of which there is a loss of pressure and a decrease in the rate at which the liquid exits the screw capillary per unit time.

Указанное свойство жидкости при прохождении используетс  в нижней части прибора, где воронка 5 дл  слива жидкости имеет дополнительный патрубок 7, расположенный выше уровн  основного отверсти  6 в трубке воронки. При таком размещении отверстий при прохождении через прибор 1 л воды через каждое из отверстий выливаетс  по 0,5 л воды.This property of passing fluid is used in the lower part of the device, where the funnel 5 for draining the liquid has an additional nozzle 7 located above the level of the main opening 6 in the funnel tube. With this arrangement of the holes, when passing through the device with 1 liter of water, 0.5 l of water is poured through each of the holes.

При большой в зкости жидкости она распредел етс  между отверсти ми в соответствующих, завис щих от в зкости соотношени х.With a high viscosity of a fluid, it is distributed between the orifices in corresponding viscosity-dependent ratios.

Предмет изобретени Subject invention

Вискозиметр, основанный на истечении жидкости через винтовой капилл р, отличающийс  тем,, что, с целью измерени  в зкости при помощи мерного калиброванного сосуда, вискозиметр снабжен воронкой 5, имеющей дл  слива жидкости в измерительный сосуд .9 дополнительное отверстие с патрубком 7, расположенное выше уровн  основного отверсти  в трубке 6 воронки и имеющее живое сечение, отличное от такового у основного отверсти  с тем, чтобы при вытекании измер емой жидкости из винтового капилл ра 3 она распредел лась между упом нутыми отверсти ми в соответствующих завис щих от в зкости соотношени х.A viscometer based on the flow of fluid through a screw capillary, characterized in that, in order to measure viscosity using a calibrated measuring vessel, the viscometer is equipped with a funnel 5 having an additional opening with nozzle 7 located above the measuring vessel .9 the level of the main hole in the tube 6 of the funnel and having a living section different from that of the main hole so that when the measured liquid flows out of the screw capillary 3 it is distributed between the said holes in respective boiling depend on the viscosity ratios.
