1, before the boot, make sure the water, gas, electricity equipment requirements have been met; make sure all fasteners are tightened again, check the door is closed.
2, open cooling water circulation, open total control power (in the wall), and the control cabinet top left corner of the switch, turn the freezer.
3, ready to inject nitrogen into the system: Check the three valves, V-3 (off), V-2 (off), V-4 (open). 4, the nitrogen partial pressure is closed, open the valve, and then transferred to the partial pressure of 0.4MPa.
5, the system nitrogen gas was introduced: V-101 (open), V-102 (open), V-103 (open too small), V-106 (open too small, so that the flow rate is about 0.5), adjusting the V triple filter -102 and between the V-103, to a pressure at 0.1MPa, V-104 (open too small, a pressure of about 0.1MPa). 6, to the oxygen concentration is below a predetermined concentration (3%) when, V-103 (off), V-2 (open), V-4 (off), and then start circulating fan 5-10 minutes, so that the oxygen concentration was maintained 3% (the system does not leak).
7, open the atomizer (frequency 0HZ), open the electric heating, the open feed pump, peristaltic pump opening (temperature does not reach the set value, can not feed), when the temperature reaches 100 ℃ (set temperature at 100 ℃), adjust the frequency of the atomizer to 30-40HZ.
8, when the hot air inlet temperature reaches the set temperature and is stabilized, the frequency of the atomizer slowly modulation 50HZ. Open peristaltic pumps, spray solvent, the outlet temperature reaches the set value, and stable (at this time whether the observed solvent spray, changes in outlet temperature).
9, when the inlet temperature and the outlet temperature reaches the set value, the solvent was quickly switched to the raw material liquid. Atomizer and adjust the knob to the required speed.
10, after the completion of the paste, the raw material liquid is switched to the solvent, and the atomizer frequency to 50HZ, and sprayed about 10 minutes, after which the feed pump is turned off, electric heating is turned off (at this time closed nitrogen), slowly decelerating atomization rotation speed to about 20HZ. When the inlet temperature was lowered to 90 ℃ off combustible gases switch, switch off the refrigerator, and the air exchange system with nitrogen (open V-3, closed V-2, open V-4), atomizer at a temperature below 90 ℃, can be closed, circulating fan can be turned off at a temperature below 60 ℃ when.
11, when the control oxygen analyzer oxygen concentration of 21%, the door can be opened to check and clean-up materials. 12, turn off the power and nitrogen each diverter valve.
