Release explanation, the course of work of the embodiment is divided into two working conditions, first be when state is equipment normal use, it is necessary to
Positive/negative-pressure constant pressure source provide negative pressure, second state for plant maintenance when, it is necessary to which positive/negative-pressure constant-voltage system provides malleation, referring to figure
It is specific as follows shown in 2：
During the first working condition, positive/negative-pressure constant pressure source system energization, a passages and b passages of all three-way magnetic valves are located
Gas inside normally open, negative-pressure cup entered three-way magnetic valve C's（a-b）Passage is released by air pump, is powered by three
Magnet valve B's（a-b）Passage is discharged into air, and two stage ink box passes through three-way magnetic valve A's（a-b）Passage connects with negative-pressure cup, keeps
Two stage ink box is set as negative-pressure cup internal negative pressure value when vacuum table A measures negative-pressure cup air pressure inside value less than Control card
During value p, Control card control air pump is worked, and the gas inside negative-pressure cup is extracted out by air pump, when vacuum table A is measured inside negative-pressure cup
When air pressure is more than or equal to Control card setting value (p+0.3kp), Control card control air pump is stopped, and realizes inside negative-pressure cup
Stable gas pressure between the atmospheric pressure value p that Control card is set ~ (p+0.3kp), atmospheric pressure value fluctuation only has 0.3kp, corresponding printing
The shower nozzle of equipment is stable negative pressure atmospheric pressure value.
