Description
Technical Field
The utility model relates to a temperature measurement technical field specifically is a wide temperature range dropping point survey device of lubricating grease.
Background
At present, the domestic dropping point test has manual test equipment and a small amount of automatic test equipment. The manual test requires the observation of each test tube and the recording of the temperature as soon as the drop comes down, and if several samples are tested simultaneously and the drop comes down substantially simultaneously, the recording is not done and the result is missed. A small amount of automatic test equipment adopts photoelectric detection, and because the metal bath temperature is very high and reaches more than 300 ℃, a photoelectric tube cannot be too close to the metal bath temperature, the penetration force of the photoelectric tube is not strong, and the detection distance cannot be too far away. For long-distance detection, a modulation signal is needed, and the judgment of the dropping point is very insensitive after the modulated photoelectric signal passes through the glass test tube. In addition, the wall thickness of the glass test tube is uneven, the condition that the dropping point cannot be detected after the test tube is replaced can occur, for example, the application number is CN201620118553.1, the name is 'a lubricating grease four-hole dropping point tester with a wide temperature range', the defects exist, laser is adopted for detecting the dropping point, the dropping point can be easily and accurately detected due to the fact that the laser brightness is high, the irradiation distance is long, and a heat insulation structure does not exist in a comparison file, so that the heat of a metal bath is easy to lose, and the temperature of the metal bath is uneven.
