Technical Field

[0002] Viscometer is an instrument used to measure the viscosity of fluids (liquids and gases). Viscosity is a physical quantity that indicates the internal friction of a fluid when it flows. It is the ability of a fluid to resist deformation and is an important indicator used to identify certain finished or semi-finished products. The viscosity varies with different fluids and changes with temperature. There are three main types of viscometers: capillary viscometers, rotational viscometers, and falling ball viscometers. The principle of the rotational viscometer is that the rotor drives the butterfly spring to rotate, and the viscosity is measured by the change in torque.
[0003] The existing rotational viscometer has a single detection method and cannot measure the viscosity of the sample under test at different temperatures, resulting in relatively simple measurement data. At the same time, the viscosity of some colloids is relatively small, and the rotor accuracy is insufficient, resulting in inaccurate measurement results.
[0004] Therefore, a rotary viscosity measuring device is needed. Utility Model Content

There are two electromagnets 15, and the two electromagnets 15 are symmetrically arranged along the slot 14. The electromagnet 15 is electrically connected to the controller 9. A snap ring 13 is clamped on the outside of the measuring cup 7, and the snap ring 13 is adsorbed on the electromagnet 15. A spring 17 is fixedly installed in the slot 14, and a pad 16 is fixedly installed on the top of the spring 17.
[0022] In this embodiment, the colloid to be tested is placed in the measuring cup 7, the snap ring 13 is clamped on the outside of the measuring cup 7, and the measuring cup 7 is inserted into the slot 14. The measuring cup 7 pushes the pad 16 to squeeze the spring 17, so that the spring 17 is in a compressed state.

[0023] Example 2
[0024] Furthermore, based on Example 1, the present invention proposes a solution: the amplifier includes a sleeve 12, an external thread is processed under the rotor 6, an internal thread is processed on the inner wall of the sleeve 12, the sleeve 12 is meshed with the rotor 6, and a stirrer 10 is fixedly installed on the outside of the sleeve 12.

[0025] In this embodiment, during measurement, the sleeve 12 of the amplifier is first screwed into the rotor 6, and the rotor 6 is fixed to the rotary measuring instrument 4. The lifting rod 3 is adjusted so that the bottom of the rotor 6 is inserted into the measuring cup 7.

By installing an array of agitator plates 10 on the outside of the sleeve 12, the resistance of the colloid is increased. Since the area of the agitator plates 10 is fixed, the viscosity is amplified without affecting the experimental results. Therefore, colloids with lower viscosities can be tested, and the experimental results are more accurate.
[0026] Working principle:
[0027] The colloid to be tested is placed in the measuring cup 7, the clamping ring 13 is clamped on the outside of the measuring cup 7, and the measuring cup 7 is inserted into the clamping slot 14. The measuring cup 7 pushes the pad 16 to squeeze the spring 17, so that the spring 17 is in a compressed state. At the same time, the electromagnet 15 is adsorbed on the clamping ring 13 to fix the measuring cup 7 to avoid shaking during the measurement process. The liquid grease is discharged into the constant temperature chamber 18 through the water supply pipe 8. According to the experimental needs, the experimental temperature is set by the controller 9, and the resistance wire 19 heats the liquid grease. The thermal stability of the liquid grease is higher, and by setting the temperature sensor 20, the temperature sensor 20 can stabilize the temperature of the liquid grease, thereby maintaining a constant temperature during the detection process, and can be used for testing colloids under different temperature environments. The viscosity is tested. After the test process, the controller 9 turns off the circuit of the electromagnet 15. At this time, the compressed spring 17 pushes the pad 16 up, and then the measuring cup 7 can be pushed out. When measuring, first screw the sleeve 12 of the amplifier into the rotor 6, fix the rotor 6 and the rotary measuring instrument 4, adjust the lifting rod 3, so that the bottom of the rotor 6 is inserted into the measuring cup 7, start the rotary measuring instrument 4, and the rotary measuring instrument 4 drives the rotor 6 to rotate, so that the viscosity of the colloid can be measured. By installing an array of agitator plates 10 on the outside of the sleeve 12, the resistance of the colloid is increased. Since the area of the agitator plates 10 is fixed, while amplifying the viscosity, it does not affect the experimental results. Therefore, colloids with lower viscosity can be tested, and the experimental results are more accurate.
