Description

Изобретение относитс  к области исследовани  жидкостей и может быть использовано дл  определени  времени жизни капель на границе раздела жидкость - жидкость, например , капель нефти на границе вода - нефть. Известно устройство дл  определени  времени жизни капель, включающее шприц с изо гнутым капилл ром, систему дл  подачи исследуемой жидкости из шприца в рабочую емкость . Однако получение капель разного объема, невозможно, что приводит к ошибкам при проведении эксперимента. Наиболее близким техническим решением к изобретению  вл етс  устройство дл  измерени  времени жизни капель, включающее шпрш с капилл ром дл  исследуемой жидкости , шприц с капилл ром дл  разделительной жид кости , рабочую емкость и систему дл  подачи жидкости в капилл ры 2j. Однако капли разделительной жидкости не всегда равномер- но попадают в капнлл р дл  исследуемой жидкости , из-за чего снижаетс  качество эксперимента . Цель изобретени  - повышение достоверности результатов. Дл  этого в предлагаемом устройстве капилл р дл  разделительной жидкости введен в капилл р дл  исследуемой жидкости. На чертеже представлена схема предлагаемого устройства дл  измерени  времени жизни капель. Устройство включает шприц 1 с капилл ром 2 исследуемой жидкости, шприц 3 с капилл ром 4 дл  разделительной жидкости, введенным в капилл р 2, рабочую емкость 5, микрометрические винты 6 и 7 дл  подачи исследуемой и разделительной жидкости в капилл ры . Устройство закреплено на штативе 8. После заполнени  шприца 1 исследуемой, а шприца 3 и рабочей емкости 5 разделительной жидкостью с ломощью микрометрического винта 7 капилл р 2 заполн ют исследуемой жидкостью до места ввода капилл ра 4. С помощью микрометрического винта 6 заполн ют разделительной жидкостью капилл р 4 и часть капилл ра 2 от его конца до места ввода капилл ра 4. С помощью микрометрического винта 7 в зан тую разделительной жидкостью часть капилл ра 2 выдавливаютThe invention relates to the field of liquid research and can be used to determine the lifetime of drops at the liquid-liquid interface, for example, oil drops at the water-oil interface. A device for determining the lifetime of the droplets, comprising a syringe with a curved capillary, is known, a system for supplying the test liquid from the syringe to the working container. However, obtaining drops of different volume is impossible, which leads to errors during the experiment. The closest technical solution to the invention is a device for measuring the lifetime of the droplets, including a splash with a capillary for the test liquid, a syringe with a capillary for separating liquid, a working container and a system for supplying the liquid to the capillaries 2j. However, the droplets of the separation liquid do not always evenly fall into the capsule for the liquid under investigation, which reduces the quality of the experiment. The purpose of the invention is to increase the reliability of the results. To this end, in the proposed device, a capillary for the separation fluid is introduced into the capillary for the test liquid. The drawing shows the scheme of the proposed device for measuring the lifetime of droplets. The device includes a syringe 1 with a capillary 2 of the test liquid, a syringe 3 with a capillary 4 for the separation fluid introduced into the capillary 2, a working container 5, micrometric screws 6 and 7 for feeding the test and separating fluid into the capillaries. The device is mounted on a tripod 8. After filling the syringe 1 under test, and the syringe 3 and working tank 5 with a separating fluid with a micrometer screw 7 capillary p 2, the test liquid is filled to the place where the capillary 4 is inserted. The capillary separator p 4 and part of the capillary 2 from its end to the point where the capillary 4 is introduced. Using a micrometer screw 7, squeeze out the part of the capillary 2 occupied by the separation liquid
