Description

Technical Field

[0001] The utility model relates to the technical field of grease processing, and specifically, to a grease apparent viscosity measuring instrument. Background Art

[0002] Viscosity can also be called fluidity, which refers to the resistance shown by a fluid to flow. When a fluid (gas or liquid) flows, when a part flows on another part, it is subject to resistance, which is the internal frictional force of the fluid. To make the fluid flow, a tangential force needs to be applied in the fluid flow direction to counteract the resistance.

[0003] The physical meaning of the viscosity coefficient (abbreviated as viscosity) η is: in two liquid layers with a unit distance apart, the tangential force required to maintain a unit velocity difference per unit area of the liquid layer. Its unit in the centimeter-gram-second (c·g·s) system is poise (g·cm-1·s-1), and in the SI system is Pascal-second (Pa·s or kg·m-1·s-1), 1 poise = 0.1 Pa·s.

[0004] Viscosity is also called the coefficient of viscosity, which is a physical quantity measuring the viscosity of a fluid. For two parallel liquid layers in a fluid with a distance dx apart, due to internal friction, there is a velocity gradient dv / dx between the liquid layers perpendicular to the flow direction. When the velocity gradient is 1 unit, the viscous force F (also called the internal frictional force) generated on the contact surface S of adjacent flow layers is the viscosity, denoted by η: η =, unit: Pa·s. Its magnitude is related to the composition of the substance. The greater the intermolecular force, the greater the viscosity. When the composition remains unchanged, the viscosities of solids and liquids decrease with the increase in temperature (the opposite is true for gases), and their relationship can be roughly expressed by the formula: η = η0Exp(E / KT), where η0 is a constant, E is the activation energy, K is the Boltzmann constant, and T is the absolute temperature.

[0005] During the viscosity detection process of grease, if the consistency of the grease is too high, a wall-hanging phenomenon will occur. If most of the grease adheres to the inner side wall of the cylinder, it will cause the stirring detection to be unable to proceed. In view of this, a grease apparent viscosity measuring instrument is developed. Content of the Utility Model

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0030] As Figures 1 to 4 shown, this embodiment proposes a grease apparent viscosity measuring instrument, including

[0031] a measuring table 1, and an equipment box 2 is arranged on the measuring table 1;

[0032] a stirring and detecting assembly 3, and the stirring and detecting assembly 3 is arranged on the measuring table 1;

[0033] The stirring and oscillating assembly 4 is arranged on the lower end face of the measuring table 1;

[0034] The stirring and detecting assembly 3 includes a limit disc 3-1 which is arranged on the measuring table 1. A supporting vertical frame 3-2 is arranged on the measuring table 1. A supporting disc 3-3 is arranged on the supporting vertical frame 3-2. A telescopic cylinder 3-4 is arranged on the upper end face of the supporting disc 3-3. The telescopic end of the telescopic cylinder 3-4 inserts into the supporting disc 3-3. The telescopic end of the telescopic cylinder 3-4 is connected with an output motor 3-5. A stirring rod 3-6 is arranged at the output end of the output motor 3-5. Stirring blades 3-7 are arranged on the stirring rod 3-6. A sealing cover 3-8 is arranged on the bottom surface of the output motor 3-5. A telescopic rod 3-9 is arranged between the sealing cover 3-8 and the supporting disc 3-3.

[0035] In this embodiment, a grease container is placed in the limit disc 3-1 of the stirring and detecting assembly 3. After the telescopic cylinder 3-4 drives the sealing cover 3-8 to be buckled in the grease container, stirring is carried out by the output motor 3-5. The sealing cover 3-8 and the limit disc 3-1 are hermetically inserted, which can ensure that the temperature in the sealing cover 3-8 will not be lost. The telescopic rod 3-9 is used to improve the stability of the sealing cover 3-8 during the lifting process.

[0036] Specifically, the telescopic rod 3-9 is composed of a sliding rod and a sleeve pipe inserted between them. The sealing cover 3-8 is a cylindrical cover body. The sealing cover 3-8 and the limit disc 3-1 are inserted and connected. A sealing ring groove 3-10 is arranged at the inner top of the sealing cover 3-8.

[0037] In this embodiment, the sliding of the sliding rod in the sleeve pipe realizes the telescopic effect of the telescopic rod 3-9. The sealing ring groove 3-10 is used for the sealing of the grease container.

[0038] Furthermore, the stirring and oscillating assembly 4 includes an oscillating disc 4-1. A part of the oscillating disc 4-1 is embedded in the measuring table 1. The oscillating disc 4-1 is located inside the limit disc 3-1. A limit disc 3-1 is arranged on the lower end face of the oscillating disc 4-1. An oscillating motor 4-3 is arranged at the lower end of the measuring table 1. The output end of the oscillating motor 4-3 is connected with a driving cam 4-4. The driving cam 4-4 is in contact with the limit disc 3-1.

[0039] In this embodiment, after the grease container is placed on the oscillating disc 4-1, the oscillating disc 4-1 bears the gravity, so that the oscillating disc 4-1 always keeps in contact with the driving cam 4-4. After the oscillating motor 4-3 drives the driving cam 4-4 to rotate, the oscillating disc 4-1 generates an oscillating effect, so that the grease hanging on the wall in the grease container falls off.

[0040] Further, a positioning key 4-5 is provided on the side surface of the oscillating disk 4-1. The positioning key 4-5 is embedded in the measuring table 1. The output motor 3-5 is fixedly connected to the sealing cover 3-8 by bolts. The output end of the output motor 3-5 is inserted into the sealing cover 3-8. The oscillating motor 4-3 is fixedly connected to the measuring table 1 by bolts.

[0041] In this embodiment, the positioning key 4-5 is used for limiting the oscillating disk 4-1 to prevent the oscillating disk 4-1 from rotating self, and to ensure the smoothness of the up and down sliding of the oscillating disk 4-1.

[0042] Further, the limiting disk 3-1 is of a C-shaped structure. The diameter of the limiting disk 3-1 matches the diameter of the sealing cover 3-8. Support feet 5 are provided on the lower end surface of the measuring table 1. The support feet 5 are arranged at the four corners of the lower end surface of the measuring table 1. A sealing ring gasket 6 is provided on the inner top of the sealing ring groove 3-10. The sealing ring gasket 6 is attached inside the sealing ring groove 3-10. Both the oscillating disk 4-1 and the support disk 3-3 are of circular structures.

[0043] In this embodiment, the support feet 5 are used to support the measuring table 1, and the sealing ring gasket 6 is used for sealing between the sealing cover 3-8 and the grease container.

[0044] When stirring detection is required, a grease container is placed in the limiting disk 3-1 in the stirring detection assembly 3. After the sealing cover 3-8 is driven by the telescopic cylinder 3-4 to be buckled in the grease container, stirring is performed by the output motor 3-5. The sealing cover 3-8 and the limiting disk 3-1 are hermetically inserted, which can ensure that the temperature in the sealing cover 3-8 will not be lost. After the oscillating disk 4-1 and the grease container are placed on it, they bear gravity, so that the oscillating disk 4-1 always remains in contact with the driving cam 4-4. After the oscillating motor 4-3 drives the driving cam 4-4 to rotate, the oscillating disk 4-1 generates an oscillating effect, so that the grease adhering to the wall of the grease container falls off.

[0045] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
