Rheometer intended for determination of rheological properties of non-Newtonian fluids, preferably the rheologically instable fluids

摘要

reometr intended for determining characteristics reologicznych non-newtonian liquids, especially vulnerable reologicznie is equipped with a vertically situated, placed in a jacketed vessel (10) termostatuju0105cym pressure vessel (1) closed head (9), in which the know found to achieve test liquid (18).the compressed nitrogen (16) and which is mounted over the sensor termometrycznego (17) placed inside a pressure tank (1). in the bottom of the pressure vessel (1) are przelotowe openings in which are mounted intakes placed in metal fittings and also termostatowanych capillaries (3).inside a pressure tank (1) is placed rotating working element (7) reometru.the working element (7) is deposited on the inside of a hollowed shaft whose one end is uu0142ou017cyskowany in the lid (2) of the vessel (1) separating the pressure vessel (1) from the head (9), and the other end of the working element (7) is located near the bottom of the container c iu015bnieniowego (1),the working element (7) is connected with an electric motor equipped with a device for the control and stabilizing his speed, containing system for measuring rotational frequency and system for measuring tangential stress in the test liquid.departures of capillaries (3) are located inside the metal frameworks, which lower ends are placed in the bushes mounted in openings in the bottom of the leading przelotowych dishes termostatuju0105cego.the capillaries (3) are closed resilient stoppers attached to the perforowanego plate (4) located inside a pressure tank (1), coupled via a mandrel (5) with a lever (6) with electromagnetic actuator zu0142u0105czonego supply system equipped with meter time, placed within the head (9) reometru,reometr contains at least three capillaries (3) of different lengths and / or of different diameters. the torque element (7), working under the lid (2) of the vessel (1) is embedded circular rbt (21) with blades attached to its outer surface.
