How to inspect the uniformity of the cooling air pressure in the chiller of the glass tempering furnace? 

Raise the upper chiller of the glass tempering furnace to 200 mm from the roller table, make the positions of the blower nozzles 50 mm inward from the front and rear ends of the second air pipes from the entrance and exit of the chiller as the sampling spots, use an electronic micro compressor with level 1 accuracy to measure the air pressure of the chiller and take the average of the 4 measuring spots to compare with the maximum and minimum values.
