(54) РОТАЦИОННЫЙ ВИСКОЗИГ№ТР(54) ROTATIONAL VISKOZIG.TR

Изобретение относитс  к приборам дл  измерени  в зкости жидкостей, в частности к ротационным вискозиметрам . Известен ротационный вискозиметр, содержавши измерительный цилиндр, погруженный в исследуемую среду, при вод и схему измерени  крут щего момент а 1 . Известен ротационный вискозиметр 2, состо щий из наружного цилиндра , служащего емкостью дл  исследуемой жидкости, и внутреннего полого вращающегос  цилиндра с приводом. Кроме того, вискозиметр имеет устрой ство дл  измерени  величины момента и скорости вращени  внутреннего ци .линдра, по изменению которых суд т . о в зкости исследуемой жидкости. Недостатком описанного ротационного вискозиметра  вл етс  сложность конструкции: привода внутреннего цилиндра и сложной системы дл  контрол  изменени  величины момента и ско рости вращени  внутреннего цилйндоа Цель изобретени  - упрощение кон струкции . Поставленна  цель достигаетс  тем, что привод вращающегос  цилиндр выполнен в виде двух диаметрально расположенных в цилиндре посто нных магнитов, образующих магнитное пОЛё, взаимодействующее с магнитным полем Земли. При этом магниты установленытак- , что их одноименные полюса направленыв одну сторону, а вектор индукции образованного ими пол  лежитв плоскости, перпенда кул ркой оси вращени  цилиндра. На чертеже показан предлагаемый ротационный вискозиметр в разрезе. Ротационный вискозиметр содержит емкость 1 с исследуемой жидкостью, крышку 2 с фиксирующим винтом 3, закрепленную в центре емкости ось 4, на которой свободно установлен вращающийс  цилинда 5 со штифтом б и закреплена стрелка 7. Во вращающемс  цилиндре 5 имеютс  два посто нных магнита 8,9, установ- ; ленных таким образом, что,их одноименные полюса направлены в одну сторону , а вектор индукции образованного, ими магнитного пол  лежит в плоскостиJ перпендикул рной оси вращени  цилнндра . На крышке 2 закреплены упор 10 и шкала 11, отградуированна  в единицах в зкости. На вращающемс  цилиндре имеетс  метка 12.The invention relates to devices for measuring the viscosity of liquids, in particular to rotary viscometers. A rotary viscometer is known, which contains a measuring cylinder immersed in the medium under investigation, with water and a torque measuring circuit a 1. A rotational viscometer 2 is known, consisting of an outer cylinder serving as a reservoir for the liquid under study and an internally rotating rotary cylinder with a drive. In addition, the viscometer has a device for measuring the magnitude of the torque and the rotational speed of the inner cylinder, from which changes are judged. viscosity of the liquid under investigation. The disadvantage of the rotary viscometer described is the complexity of the design: driving the inner cylinder and a complex system to control the change in the torque value and the rotation speed of the inner cylinder. The purpose of the invention is to simplify the design. The goal is achieved by the fact that the drive of a rotating cylinder is made in the form of two permanent magnets diametrically located in the cylinder, forming a magnetic field that interacts with the Earth's magnetic field. At the same time, the magnets are set to such that their like poles are directed to one side, and the induction vector of the floor they form lies in the plane perpendicular to the cylinder’s rotating axis. The drawing shows the proposed rotational viscometer in the section. The rotational viscometer contains a container 1 with the liquid under investigation, a cover 2 with a fixing screw 3, an axis 4 fixed in the center of the container, on which a rotating cylinder 5 is freely mounted with a pin b and an arrow 7 is fixed. In the rotating cylinder 5 there are two constant magnets 8.9 , set-; such that their poles of the same name are directed in one direction, and the induction vector of the magnetic field formed by them lies in the planeJ of the perpendicular axis of rotation of the cylinder. On the cover 2, the stop 10 and the scale 11 are fixed, calibrated in units of viscosity. There is a mark 12 on the rotating cylinder.
