PLC sends out the instruction that shuts down to fluid infusion pump 3-6, and fluid infusion terminates.When liquid level is less than extreme lower position in liquid storing barrel, feed back to
PLC, at this time PLC send out alarm, audible-visual alarm lamp 3-1 is simultaneously emitted by sound and light warning.
The course of work：A kind of cycle liquid-adding device of roll coater, unit begin to use roll coater, ON cycle cooling water,
Cooling water flows into cooling water circulation chamber 2-1 from batea bottom coohng water inlet 2-4, then is flowed out from cooling water outlet 2-5.Cycle adds
Liquid pump 3-2 is opened, and roller coating liquid is by recycling liquid-feeding tube 3-3 constantly to batea workspace 2-7 liquid feedings, when liquid level exceeds overflow baffle
After 2-3, roller coating liquid overflows above overflow baffle 2-3, flows into batea overflow area 2-8, and batea overflow area 2-8 has certain roller coating liquid
It is slowly flowed back in liquid storing barrel 3-4 from cycle liquid return hole 2-6 outflows by recycling liquid back pipe 3-8 afterwards, cycle fluid filling pump 3-2's
Under effect, roller coating liquid is constantly pumped into batea workspace 2-7, and under gravity, the roller coating liquid stream of batea overflow area 2-8 returns storage
Liquid bucket 3-4, continuous cycle liquid feeding like this, during liquid feeding, the roller coating liquid liquid level of 2-7 is kept off in overflow always in batea workspace
Plate 2-3's is highly consistent, both the level altitude of 12CM.When liquid is less than half in liquid storing barrel 3-4, middle position floating ball 3-10 in bucket
Sensor detects that liquid level is less than half, and information feeds back to PLC, and PLC sends out drawing liquid instruction, after drawing liquid instruction is sent out, if
The pressure sensor 3-13 of ground liquid bucket 3-12 placement locations has pressure, then illustrates that liquid bucket 3-12 is in place and has liquid, pump normally opens
Dynamic drawing liquid.If without pressure, illustrate that liquid bucket 3-12 in place or liquid bucket without liquid, pump without cannot normally open at this time
It is dynamic, PLC is fed back at this time, and PLC sends out liquid bucket 3-12 not in place or aneroid alarms, audible-visual alarm lamp hair to audible-visual alarm lamp 3-1
Go out light light warning.When liquid level reaches extreme higher position in liquid storing barrel 3-4, high-order floating ball 3-9 sensors send out high liquid
Position signal feeds back to PLC, and PLC sends out the instruction that shuts down to fluid infusion pump 3-6, and fluid infusion terminates.When liquid level is less than most in liquid storing barrel
When lower position, PLC is fed back to, PLC sends out alarm at this time, and audible-visual alarm lamp 3-1 is simultaneously emitted by sound and light warning.
It should be noted that above-described embodiment, is not used for limiting the scope of protection of the utility model, in above-mentioned technical side
Made equivalents or replacement each fall within the range that the utility model claims are protected on the basis of case.
