Description
Изобретение относитс к области энергетики и гадравлики и может быть использовано например , дл определени характеристик фитилей тепловых труб. Известио устройство дл определени высоты подн ти жидкости по капилл рно-пористому образцу, содержащее рабочую камеру, частично заполненную пробной жидкостью и снабженную в верхней части отверстием дл закреплени конца исследуемого образца 1. Высоту подн ти определ ют визуально по видимой границе смачивани предварительно осушенного фитил при его погружении в пробную жидкость . Недостатком известного устройства вл етс невысока точность, а также невозможность измерений в том случае, если жидкость не видима на пористом образце. Целью изобретени вл етс повышение точности. Это достигаетс тем, что над отверстием дл закреплеии конца исследуемого образца расположена сообщающа с с ним дополнительна ка мера дл контрольной жидкости, при этом ра боча камера соединена с источником сжатого газа и снабжена средством дл изменени уровн пробной жидкости. На чертеже приведена схема предлагаемого устройства. Устройство содержит рабочую камеру 1, частично заполненн)то пробной жидкостью 2. В верхней части рабочей камеры 1 выполнено отверстие , закрытое сменным коническим злементом 3, в котором закреплен исследуемый образец 4. Над узлом креплени образца расположена дополнительна камера 5 дл контрольной жидкости. Дл изменени уровн контрольной жидкости в дополнительной камере устройство снабжено вытеснителем 6. Рабоча камера в верхней части соединена при помсщи трубопровода 7 и вентил 8 с источником сжатого газа и снабжена в нижней части сильфоном 9 дл изменени уровн пробной жидкости. Устройство работает следующим образом. Дополнительна камера 5 заливаетс контрольной жидкостью до уровн , лежащего ниже кра гнезда дл конического элемента 3. Затем вставл ют конический элемент 3 с закрепленным.The invention relates to the field of energy and hydraulics and can be used, for example, to determine the characteristics of heat pipe wicks. A device for determining the elevation height of a liquid through a capillary-porous sample, containing a working chamber, partially filled with test liquid and provided with an opening in the upper part for fixing the end of the test sample 1, is visible. its immersion in the test fluid. A disadvantage of the known device is the low accuracy as well as the impossibility of measuring if the liquid is not visible on the porous sample. The aim of the invention is to improve the accuracy. This is achieved by the fact that an additional chamber for the control fluid communicating with it is located above the hole for fixing the end of the sample under investigation, while the working chamber is connected to a source of compressed gas and provided with means for changing the level of the test fluid. The drawing shows a diagram of the proposed device. The device contains a working chamber 1, partially filled with a test liquid 2. In the upper part of the working chamber 1 there is a hole closed by a replaceable conical element 3 in which the sample 4 is fixed. Above the sample fixing unit is an additional chamber 5 for the test liquid. To change the level of the control liquid in the auxiliary chamber, the device is equipped with a displacer 6. The working chamber in the upper part is connected with the pipeline 7 and the valve 8 to a source of compressed gas and equipped with a bellows 9 in the lower part to change the level of the test liquid. The device works as follows. The additional chamber 5 is filled with the control liquid to the level lying below the edge of the socket for the conical element 3. Then the conical element 3 is inserted with the fixed one.
