Description

Rotary viscometer convenient to position Technical Field The application relates to the technical field of rotary viscometers, in particular to a rotary viscometer convenient to position. Background With the development of science and the improvement of industrial production, it is becoming very important to determine the viscosity of a substance, and a rotational viscometer can be used to determine the viscosity and flow behavior of a polymer liquid. Because most polymers are processed and formed under viscous flow conditions, it is very important to grasp the viscous flow state performance rule for measuring the viscosity of the polymers in the polymer production process. The utility model discloses a rotary viscometer (publication number: CN 206095863U), which solves the problems that electric energy waste is easy to cause and the service life of a motor is easy to shorten when the motor idles, and the technical scheme is characterized in that a viscosity measuring device comprises a rotor and a motor for driving the rotor, a bearing tray is arranged below the rotor, a container for containing a sample to be measured is arranged on the upper surface of the bearing tray, and the rotary viscometer further comprises a pressure detecting unit, a comparing unit and an executing unit; on the contrary, when the container is not filled with the sample to be measured or the quantity of the sample to be measured is insufficient, the pressure value between the container and the bearing plate is smaller than the standard pressure value, and the motor cannot be started at the moment, so that the motor is prevented from idling, the purpose of saving electric energy is achieved, and the service life of the motor can be prolonged.
