换阀比换TIC板来的直接.

从问题上看就是青色不降温或降温慢,浅层次的原因是冷水供应,检查一下电磁阀
深层次的原因有可能是其他引起的,比如某色加热慢,持续加热时因加热和降温过程互斥,导致青色没有降温.另可能制冷机的压力是否为6,等等都可以检查

青色的油墨温度是可以bypass的,但是温度高了之后导电性会发生变化,进而影响颜色变化.实在不是上上之举.但作为诊断手段是可以的.

建议对换电磁阀测试,如果仍然出现请使用spv监测4色油墨温度变化及水阀开启时间等以便分析
5000的油墨温度传感器在tic板上,一般不存在虚接的问题

总版主大哥，提问题的哥们会用SPV那就不是一般人了，还发帖作甚。

大早晨的不睡觉,搞咩啊?

SPV还是很easy的,选两个参数么自己跑跑

帅哥 你说的那是读ITM温度的传感器,和油墨不相关的.或者就是我没见过橡皮温度不对,要求冷却青色油墨的.

制冷机4天以上停机是要预热压缩机的 否则有可能会出现帅哥说的R134a液化 预热时间不少于6小时

no,you should swop the solenoid valve first.

[kcdsw]

why don't you swop valve first? i told you it's no relation between your problem and TIC board. the temp sensor on TIC board is more senstive , we can trust it.
as you mention that all inks have this problem ,i am thinking about chiller may have some problem ,you need to check the water pump outlet pressure and water graded filter pressure, the chiller work condition etc.
and,you need to verfity that the image oil cooling rate is good or not , it indicate us two things,one is the oil filter,another is chiller work condition .if the oil filter is blocking too much,the image oil can not be cooling down as normal, so the image oil in oil tank will warming up fast when you print something.but even so , it still can not help us to troubleshot your problem , because the image oil can not affert ink temp too much.
ok,let's go back to another things about image oil cooling down,the chiller work condition,if the chiller work condition is bad ,you will not only see ink temp problem but also image oil cooling problem .so that's the reason i want you to verfity the image oil cooling rate . as your unknown chiller model , i can't give you further suggestion about chiller but clean condenser.
in addtion , the cyan ink's temp is more higher than other inks because the cyan BID is nearest BID to ITM.

chiller water pump pressure
chiller water filter pressure
chiller condenser blocking etc

都洗了，不行.........

告诉你了跟那个没有关系 你慢慢洗

chiller water pump pressure
chiller water filter pressure
chiller condenser blocking etc
应该要怎样检查啊？？？因为我没有碰过那chiller....
pump pressure 再哪？？
filter pressuer 再哪？？？
还有condenser呢？？？
我真的什么都不懂....麻烦啦

检查制冷机的工作状态
1,水泵出水压力 约为5.5-6bar
2,制冷机回水压力(过滤器压力) 一般小于1.5bar
3,清洁制冷机蒸发器,保证通风量
