Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pour point experiment, and specifically relates to a pour point experiment instrument. Background Art
[0002] The pour point refers to the lowest temperature at which the tested sample can flow under the specified test conditions; the freezing point refers to the highest temperature at which the oil surface of the tested sample no longer moves under the specified test conditions, both expressed in °C, and are conventional indicators used to measure the low-temperature fluidity of lubricating oils, etc. The pour point of the same oil is slightly higher than the freezing point by a few degrees. In the past, the freezing point was commonly used, and now the international standard is the pour point. If the pour point or freezing point is too high, the low-temperature fluidity of the oil is poor. People can consider the measures to be taken during transportation, storage, receiving and dispatching under low-temperature conditions based on the pour point of the oil, and can also be used to evaluate the low-temperature service performance of certain oils.
