1.An overview of the
Used for testing closed flash point value of petroleum products.Adopting foreign advanced technology, the liquid crystal TET pure color touch screen, all-chinese display man-machine dialogue interface, with prompt menu prompt input for parameters such as prevalue temperature, oil test mark, atmospheric pressure, test date, etc., convenient and fast, open, fuzzy control integrated software, modular structure, in line with GB/ t261-2008 and GB/ t261-83 standards.It is an ideal substitute for imported instruments.Widely used in railway, aviation, power, oil industry and scientific research departments.
2.The instrument features
* With Chinese error operation software prompt modification function；
* Equipped with the function of parameter indication such as test date and test time；
* Automatic correction of atmospheric pressure on the test and calculation of the correction；
* Differential detection, system deviation automatic correction；
* Open cover, ignition, detection, printing data automatic completion；
* The test arm will automatically lift and land；
* Ignition mode: electronic ignition.
3.The working principle of
Under the condition stipulated by the national standard, the test sample is loaded into the test cup, and the test cup containing test oil is heated.The flash point is the lowest temperature at which the generated oil vapor and the mixed gas formed by the surrounding air contact with the flame.
Computer according to the collected by the temperature change instructions issued by the I/O port to control the heater, make the oil test temperature at a rate rise, scan cycle, ignition timing, differential detection, automatic control, when the flash is measured, a computer system stop data collection, flash fire temperature display and print the record as a result, stop heating, close the flame.
