Abstract
Reometr przeznaczony do wyznaczania właściwości reologicznych cieczy nienewtonowskich, zwłaszcza niestabilnych reologicznie jest wyposażony w usytuowany pionowo, umieszczony w otoczonym płaszczem (10) naczyniu termostatującym zbiornik ciśnieniowy (1) zamknięty głowicą (9), w której znajduje się doprowadzenie badanej cieczy (18), doprowadzenie sprężonego azotu (16) oraz w której jest zamocowany koniec czujnika termometrycznego (17) umieszczonego wewnątrz zbiornika ciśnieniowego (1). W dnie zbiornika ciśnieniowego (1) są przelotowe otwory, w których są zamocowane wloty umieszczonych w metalowych oprawach i także termostatowanych kapilar (3). Wewnątrz zbiornika ciśnieniowego (1) jest umieszczony obrotowy element roboczy (7) reometru. Element roboczy (7) jest osadzony na wydrążonym wewnątrz wale, którego jeden koniec jest ułożyskowany w pokrywie (2) zbiornika ciśnieniowego (1) oddzielającej zbiornik ciśnieniowy (1) od głowicy (9), zaś drugi koniec wału elementu roboczego (7) jest usytuowany w pobliżu dna zbiornika ciśnieniowego (1), Wał elementu roboczego (7) jest połączonym z silnikiem elektrycznym wyposażonym w urządzenie do jego sterowania i stabilizowania jego prędkości obrotowej, zawierające układ do pomiaru częstości obrotowej oraz układ do pomiaru naprężeń stycznych w badanej cieczy. Wyloty kapilar (3) znajdują się wewnątrz ich metalowych opraw, których dolne końce są umieszczone w tulejach prowadzących zamocowanych w przelotowych otworach w dnie naczynia termostatującego. Wloty kapilar (3) są zamknięte elastycznymi korkami, przymocowanymi do perforowanego talerza (4) usytuowanego wewnątrz zbiornika ciśnieniowego (1), sprzężonego za pomocą trzpienia (5) z dźwignią siłownika elektromagnetycznego (6) złączonego z układem zasilającym wyposażonym w miernik czasu, umieszczonego także wewnątrz głowicy (9) reometru, Reometr zawiera co najmniej trzy kapilary (3) o różnych długościach i/lub o różnych średnicach. Na wale obrotowego elementu roboczego (7), pod pokrywą (2) zbiornika ciśnieniowego (1), jest osadzony kołowy okap (21) z łopatkami przymocowanymi do jego zewnętrznej powierzchni.The rheometer intended for determining the rheological properties of non-Newtonian liquids, especially rheologically unstable ones, is equipped with a vertically located, surrounded by a jacket (10) thermostatic vessel, pressure tank (1) closed with a head (9), in which the test liquid (18) is located, inlet compressed nitrogen (16) and in which the end of the thermometer sensor (17) located inside the pressure vessel (1) is attached. In the bottom of the pressure tank (1) there are through holes in which the inlets located in metal housings and also thermostated capillaries (3) are fixed. Inside the pressure tank (1) there is a rotary working element (7) of the rheometer. The working element (7) is mounted on a hollow shaft, one end of which is mounted in the cover (2) of the pressure vessel (1) separating the pressure vessel (1) from the head (9), while the other end of the working element shaft (7) is located near the bottom of the pressure tank (1), the shaft of the working element (7) is connected to an electric motor equipped with a device for its control and stabilization of its rotational speed, containing a system for measuring the rotational frequency and a system for measuring the shear stress in the tested liquid. Capillary outlets (3) are located inside their metal housings, the lower ends of which are placed in guide sleeves mounted in through holes in the bottom of the thermostatic vessel. The capillary inlets (3) are closed with flexible plugs, attached to a perforated plate (4) located inside the pressure tank (1), coupled by means of a stem (5) with an electromagnetic actuator lever (6) connected to a power supply equipped with a time meter, also located inside the rheometer head (9), the rheometer contains at least three capillaries (3) of different lengths and / or diameters. On the shaft of the rotary working element (7), under the cover (2) of the pressure vessel (1), a circular hood (21) with blades attached to its outer surface is mounted.
