step three: after the heat insulation oil sleeve is installed, the circulating fan box (12) is controlled to work, so that the circulating fan box (12) accelerates the gas flow in the hollow pipe (11), further the gas in the heat insulation oil sleeve moves synchronously, and the smooth circulation of the air in the heat insulation oil sleeve is facilitated;
step four: in addition, a telescopic rod (14) on the horizontal plate (13) is controlled to work, the telescopic rod (14) drives an upper heat insulation sleeve (15) to be spliced with a lower heat insulation sleeve (6) below, the upper heat insulation sleeve (15) and the lower heat insulation sleeve (6) wrap a heat insulation oil sleeve, and a heating wire (7) is controlled to heat;
when the test value X is larger than or equal to the preset test value Y, a test signal is generated and sent to the feedback execution unit, the feedback execution unit immediately controls the servo motor (26) inside the vertical plate (2) to work after receiving the test signal, the servo motor (26) drives the filter wheel (24) to synchronously rotate through the driving shaft (25), transmission between gears is realized, the filter wheel (24) drives the gear plate (21) to rotate, the gear plate (21) drives the heat insulation oil sleeve to rotate, uniform heating of the heat insulation oil sleeve is facilitated, accuracy of equipment results is further improved, interference on data is avoided, and meanwhile, the heating speed of the heat insulation oil sleeve is facilitated to be improved.
