Abstract

The invention discloses a non-Newtonian fluid on-line rheological property testing device which comprises a base and a supporting column, the supporting column is fixedly connected with the top of the base, a cavity is formed in the base, a first screw rod is rotatably connected in the cavity, a first motor is fixedly connected to the outer wall of the base, and a second motor is fixedly connected to the outer wall of the base. An output shaft of the first motor penetrates through the outer wall of the base and extends into the cavity, the extending end of the first motor is fixedly sleeved with a first gear, the first screw rod is fixedly sleeved with a second gear meshed with the first gear, and a sliding groove is formed in one side of the supporting column; the top of the first screw penetrates through the inner wall of the cavity and extends into the sliding groove. According to the invention, through the arrangement of multiple adjusting mechanisms, the testing device can be freely adjusted, so that the use convenience of the testing device is improved.

Description

technical field [0001] The invention relates to the technical field of material performance testing, in particular to an online rheological property testing device for non-Newtonian fluids. Background technique [0002] In the fields of chemical industry, food processing, and polymer material molding, there is a non-Newtonian fluid transportation process, and the rheological properties of non-Newtonian fluid have important guiding significance for product quality control, process adjustment, and equipment improvement. At present, the rheological properties of non-Newtonian fluids are generally tested by collecting samples first, and then performing offline measurements through rheometers. Commonly used rheometers mainly include capillary rheometers and rotational rheometers. [0003] The core part of the capillary rheometer is: a set of capillary tubes with different length-to-diameter ratios, a barrel with a constant temperature heating jacket around it, and a hydraulically...
