A rotary viscometer

Abstract

The invention relates to a rotary viscometer comprising a base, a standing column, a detecting motor, a clamping sleeve seat, a detecting container and a pneumatic clamping device; the standing columnis vertically disposed on the base; the output shaft of the detecting motor is mounted on the top of the standing column; the output shaft of the detecting motor is connected with a rotor shaft for detecting the viscosity of a liquid in the detecting container; the lower portion of the standing column is provided with a rack; the clamping sleeve is provided with a rotating moving device matched with the rack; the detecting container is placed on the clamping sleeve seat; the clamping sleeve seat is provided with the pneumatic clamping device. An adjustable clamping part is arranged to adjustthe upper and lower positions of the detecting container relative to the motor, and accurately clamps the detecting container, thereby avoiding displacement of the container during the detecting process, and improving the safety of experiments; the consistency of the axis of the motor and the center axis of the container can be ensured, testing accuracy can be improved, and the detection containerhas own heating device to heat an internal liquid to be tested.

Description

【Technical field】 [0001] The invention relates to a viscometer, in particular to a rotary viscometer capable of rapidly detecting fluid viscosity, and belongs to the technical field of fluid viscosity testing devices in mechanical engineering. 【Background technique】 [0002] Viscosity is an indicator of fluid flow resistance. With the development of industrial production and scientific research, the determination of the viscosity or fluidity of fluid substances has become an essential material test. It is used in the quality control of the production process and the final It plays an important role in product performance evaluation, and plays a decisive role in identifying product quality, seeking the best production process and developing new products. The viscometer is a general-purpose measuring instrument used to continuously measure the viscosity of various Newtonian liquids and the apparent viscosity of non-Newtonian fluids in industrial production processes.

Problems solved by technology

[0004] However, the problems in the existing design are: (1) due to the heavy self-weight of the detection motor, it is inconvenient to operate when adjusting the up and down position slippage; It is not conducive to controlling the vertical of the central axis of the detection motor, and then affects the measurement accuracy; (2) because the detection container and the main body of the machine base are separated, and the detection container must be cleaned after each test, it is difficult to detect the detection by human eyes. The position adjustment of the detection container is difficult to ensure the accuracy requirements
