温度对润滑脂的影响

来源:https://www.smxnykj.com/ 发布时间:日期:2022-09-15
温度对润滑脂的流动性具有较大影响,温度升高,润滑脂变软,使得润滑脂附着性能降低而易于流失。另外,在较高温度条件下还易使润滑脂的蒸发损失增大、氧化变质和分油严重。高温性好的润滑脂可以在较高的使用温度下保持其附着性能,其变质失效过程也较缓慢。
The temperature has a great influence on the fluidity of the grease. When the temperature rises, the grease becomes soft, which reduces the adhesion of the grease and makes it easy to lose. In addition, it is easy to increase the evaporation loss, oxidation deterioration and oil separation of lubricating grease at higher temperatures. Lubricating grease with good high-temperature performance can maintain its adhesion at a higher service temperature, and its deterioration and failure process is also slow.
评定润滑脂高温性的指标主要有滴点、蒸发量和漏失量。
The main indexes for evaluating the high temperature property of lubricating grease are dropping point, evaporation and leakage.
润滑脂的滴点是其在规定的试验条件,润滑脂达到一定流动性的低温度。它主要取决于稠化剂的种类与含量。滴点越高,润滑脂的耐热性越好。
The dropping point of the grease is the low temperature at which the grease reaches a certain fluidity under the specified test conditions. It mainly depends on the type and content of thickener. The higher the drop point, the better the heat resistance of the grease.
润滑脂的蒸发量是指在规定的试验条件下,因蒸发而引起润滑脂质量损失的百分数。润滑脂的蒸发量主要取决于所采用的基础油的种类、馏分组成和分子量。蒸发量可以定性地表示润滑脂上限使用温度。
The evaporation amount of lubricating grease refers to the percentage of lubricating grease mass loss caused by evaporation under specified test conditions. The evaporation amount of lubricating grease mainly depends on the type of base oil, fraction composition and molecular weight. The amount of evaporation can qualitatively represent the upper limit of grease use temperature.
评定润滑脂高温性能还有一项指标是测定润滑脂轴承漏失量,漏失量越大,润滑脂的高温工作性能越差
Another index to evaluate the high-temperature performance of lubricating grease is to measure the leakage of lubricating grease bearing. The greater the leakage, the worse the high-temperature performance of lubricating grease
