Detailed technical principle of boiling range instrument for petrochemical distillation process
SH6536 Automatic distillation range measuring instrument using color liquid crystal display screen, Chinese menu man-machine dialogue, wizard operation, the determination process is all automatic. According to the national standard GB/T6536 "Distillation determination of petroleum products" and GB/T6536, ASMT D86 standards, suitable for petroleum products distillation range and industrial volatile organic liquid, raw material organic solvent boiling range determination.
It adopts embedded computer, imported industrial computer, 12.1 "large screen LCD touch screen, friendly man-machine interface and convenient operation. Using single chip microcomputer and intelligent control technology, the distillation test process of heating and cooling, distillate liquid level tracking, distillation rate control, recovery of liquid volume control, temperature recording, test results printing, etc., are all automatically completed.
Main performance characteristics
Two, functions and features
● The instrument by the industrial computer machine automatic measurement and control of the whole process of testing, full touch 10.4 inch LIQUID crystal display test,
● Whole process display temperature and volume data and related curves.
● The liquid level tracking system is composed of high subdivision step American linear motor and imported photoelectric tracker.
● Cold tube temperature, measuring chamber temperature, all adopt mechanical refrigeration, compressor for foreign famous brand manufacturers. The cooling medium circulates inside. Cooling water can be checked and added once every 3 years.
● Distillation furnace heating automatic control, so that the sample from the initial distillation point to 95% of the flow rate, control within 4 ~ 5ml per minute.
● Can provide the initial distillate temperature value and the final distillate temperature value, can provide the temperature value and the flow rate of each percentage point.
Automatic detection of local atmospheric pressure, automatic correction to the standard atmospheric pressure under the temperature.
● Can choose to stop the test by steam temperature or recovery volume.
● The instrument can store, query, print test results.
