Abstract

The invention provides a viscometer. The viscometer comprises a servo motor and a viscosity sensor, wherein the servo motor comprises a servo motor body, a motor shaft, a motor rotor, a permanent magnet and a coder, wherein a first end of the motor shaft is arranged inside the servo motor body; the motor rotor, the permanent magnet, the coder are fixedly connected with the first end of the motor shaft; a second end of the motor shaft extends outside the servo motor body, and is directly and fixedly connected with the viscosity sensor; the rotation of viscosity sensor is lagged under the actionof viscosity torque generated in liquid to be tested; the coder is used for reading a lagging angle fed back by the motor shaft, and liquid dynamic viscosity of the liquid to be tested is calculatedaccording to the lagging angle. The viscometer is simple in structure, the rotation of the motor shaft and the viscosity sensor device is insusceptible to the interference of external environment, sothat the adaptivity of the viscometer in a plurality of industrial flows is improved, and the accuracy of the liquid hydraulic viscosity measured by the viscometer is increased.

Description

technical field [0001] The invention relates to the field of detection equipment, in particular to a viscometer. Background technique [0002] A viscometer is a testing device used to measure the dynamic viscosity of a liquid. Liquid dynamic viscosity determination plays an important role in the industrial sector and scientific research fields. Especially in pharmaceutical, food, chemical and other industrial processes, it is more necessary to accurately measure and control liquid dynamic viscosity to improve product quality. [0003] Existing viscometers such as figure 1 As shown, the device includes: a motor output shaft 1 , an upper plate 2 , a lower plate 3 , an elastic element 4 , and a small cylinder 5 . The motor output shaft 1 is connected with the upper disc 2, so that the upper disc 2 and the motor output shaft 1 rotate synchronously at a constant speed. The upper plate 2 and the lower plate 3 are not directly connected, but are respectively connected with two ...
