Lubricating grease detection mold

Abstract

The invention discloses a lubricating grease detection mold, relates to the technical field of lubricating grease detection, and aims at solving the problems in the prior art that errors are likely tooccur in operation of a grease cup with a small size, the thickness deviation of a grease film in the grease cup is large or damaged and the detection result is affected. According to the technical scheme, the lubricating grease detection mold comprises the grease cup, the grease cup comprises a bowl-shaped bowl part and a pipe part which is located under the bowl part and communicated with the bowl part in the vertical direction. A matching part is arranged in the grease cup and comprises a funnel-shaped separation cone, the height of the separation cone is equal to that of the bowl part, the circumferences of the top and the bottom of the separation cone are attached to the circumferences of the top and the bottom of the bowl part respectively, and penetrating holes are evenly distributed in the conical surface of the separation cone; the top wall of the separation cone is provided with a sleeve which is collinear with the central axis of the separation cone, and the separation coneis located in the sleeve. The lubricating grease detection mold is convenient to operate, the repeatable grease film is formed and the dropping point detection accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of grease detection, in particular to a grease detection mold. Background technique [0002] The dropping point of lubricating grease refers to the temperature when the lubricating grease reaches a certain fluidity under the specified test conditions. This temperature is also called the dropping point temperature of lubricating grease, which is an important index to characterize the quality of lubricating grease. [0003] The method for measuring the dropping point of lubricating oil is determined according to the national standard GB4929-85 "Measurement of the dropping point of lubricating oil". refer to figure 1 The instrument used in this measurement method includes a chrome-plated brass grease cup 1, a test tube 4, a thermometer 41, and a cork 42 for holding the sample to be tested. , used to support the fat cup 1. The fat cup 1 is bowl-shaped, with openings on the top and bottom. Press the sample fr...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: the size of the grease cup 1 is small, and when the operator manually uses the metal rod 44 to rotate in a spiral shape in the grease cup 1, it is impossible to ensure that the metal rod 44 must fit the circumference of the grease cup 1 , but it is difficult to ensure that the thickness of the lipid film in cup 1 is reproducible

At the same time, at the moment when the fat cup 1 slides out of the end of the metal rod 44, the end of the metal rod 44 is very easy to poke the lipid film and cause the lipid film to be destroyed, affecting the dropping point test results. This problem needs to be solved
