Problems solved by technology
Conventional Vicat instruments are not equipped with a cooling device, and the time required to return to normal temperature according to air cooling is close to one day, resulting in only one test per day
Some Vicat instruments provide a water-cooling interface, but this cooling method consumes a lot of water resources, and the water is easy to evaporate after being heated, resulting in an increase in internal pressure, which is not convenient for internal circulation cooling

Embodiment Construction
[0027] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.
[0028] It will be understood that the terms "first", "second" and the like used in the present invention may be used herein to describe various elements, but these elements are not limited by these terms unless otherwise specified. These terms are only used to distinguish a first element from another element. For example, a first xx script could be referred to as a second xx script, and similarly, a second xx script could be referred to as a first xx script, without departing from the scope of the present invention.
[0029] like figure 1 As shown, in one embodiment, a high-efficiency Vi...

The invention relates to the technical field of cooling equipment and systems, in particular to an efficient Vicat instrument cooling method and device and a Vicat softening point test system.The method comprises the steps that a cooling instruction is received, and the temperature of each test channel is obtained; determining the test channel which is cooled preferentially according to the temperature of each test channel; starting a circulating pump and an oil cooler to circularly cool the test channel which is cooled preferentially; collecting the temperature of each test channel in real time, determining whether to switch the test channel according to the collected temperature, and if the test channel needs to be switched, determining the test channel needing to be switched and executing a switching action to switch off or switch on the corresponding test channel; and obtaining the inlet oil temperature and the outlet oil temperature of the oil cooler when the set time is reached after any switching action, and adjusting the power of the oil cooler and the rotating speed of the circulating pump according to the obtained inlet oil temperature and the outlet oil temperature. By switching the channels and adjusting the oil temperature, the temperature difference is enlarged, the heat transfer rate is increased, and faster cooling is achieved.
Description
technical field [0001] The invention relates to the technical field of cooling equipment and systems, in particular to a high-efficiency Vicat instrument cooling method, device, and Vicat softening point testing system. Background technique [0002] Vicat softening point, vicat softening temperature (referred to as VST) - a sample of engineering plastics, general-purpose plastics and other polymers in a liquid heat transfer medium, under a certain load and a certain constant temperature heating condition, is heated by 1mm 2 The temperature at which the indenter is pressed into the depth of 1mm. Vicat softening point reflects the softening temperature of a material under specific conditions, which is related to the molecular structure and molecular weight of the material, and is a must-test item in material testing. [0003] There are many testing methods for Vicat softening point, the most commonly used and the most automated one is Vicat instrument. Since the test process...
