- Изобретение относитс к измерительной технике дл оценки фрикционных свойств глинистых корок.- The invention relates to a measurement technique for evaluating the frictional properties of clay crusts.
Известен прибор дл исследовани фрикционных свойств глинистых корок, 5 содержащий основание, установленный на нем измерительный стакан, предназначенный дл размещени в нем исследуемого материала, привод вращени стакана, контробразец, помещаемый на tO исследуемый материал и взаимодействующий с ним в процессе исследовани , . узел нагружени пары и узел регистрации силы трени , соединенный с контробразцом 1.15A known device for studying the frictional properties of clay crusts, 5 containing a base, a measuring glass mounted on it, designed to accommodate the material under study, a rotational drive of the glass, a counter sample, placed on the tO material and interacting with it during the investigation,. the loading unit of the pair and the friction force recording unit connected to counter-probe 1.15
Недостатком такого прибора вл етс низка точность измерени сил трени образца металла по глинистой корке из-за наличие скольжени между узлом передачи сил трени и штоком, 20 перекосов и неполного прилегани образца к глинистой корке.The disadvantage of such a device is the low accuracy of measuring the friction force of a metal sample on a mudcake due to the presence of a slip between the friction force transfer unit and the rod, 20 distortions and an incomplete adherence of the sample to the mudcake.
Целью изобретени вл етс повышение точности измерений.The aim of the invention is to improve the measurement accuracy.
Дп этого прибор снабжен узлом тикального перемещени узла нагружени и контробразца, а узел регистрации силы трени выполнен в виде катушки со сквозным осевым отверстием и размещенного в нем стержн с иглой на ЗОDp of this device is equipped with a unit for ticking movement of the loading unit and counter piece, and the unit for recording the friction force is made in the form of a coil with a through axial hole and a rod with a needle in the DZ located in it
конце, обеспечивающего центрирование контробразца и исследуемого материала, и двух закрепленных .на торце катушки с возможностью вращени роликов, через которые перекинута нить, один конец которой св зан с индикатором, а другой - жестко закреплен на основании .the end providing centering of the counterpiece and the test material, and two fixed coils at the end of the coil with the possibility of rotation of the rollers through which the thread is threaded, one end of which is connected to the indicator, and the other is rigidly fixed to the base.
На чертеже представлена схема прибора .The drawing shows a diagram of the device.
Прибор содержит основание 1, установленный на нем измерительный стакан 2 с днищем 3, предназначенный дл размещени в нем исследуемого материалаThe device contains a base 1, a measuring cup 2 installed on it, with a bottom 3, designed to accommodate the material under study.
4(пло-ко-параллельный песчаный фильтр с глинистой коркой), привод вращени стакана, состо щий из электродвигател 4 (flat-parallel sand filter with a mudcake), drive rotation of the glass, consisting of an electric motor
5и шкива 6, контробразец 7, соединенный с ним узел нагружени , выполненный в виде плиты 8 с грузами 9, Узел вертикального перемещени узла нагружени контробразца 7 выполнен в виде пружинного индикатора 10, пружины 11 сжати , подвижной втулки 12 и винта 13, который с помощью стальной нити5 and a pulley 6, a contra-sample 7, a loading unit connected to it, made in the form of a plate 8 with weights 9, a node of the vertical movement of the loading unit of the counter-sample 7 made in the form of a spring indicator 10, a compression spring 11, a movable sleeve 12 and a screw 13, which with the help of steel thread
14 соединен с плитой 8. Узел регистрации силы трени выполнен в виде катушки 15 со сквозным осевым отверстием , стержн 16 с иглой 17 дл центрировани исследуемого материала 4 и14 is connected to the plate 8. The friction force recording unit is made in the form of a coil 15 with a through axial bore, a rod 16 with a needle 17 for centering the test material 4 and
