During the production, you may be meet many little problems , such as barrel can not be cooled.
Barrel can not be cooled have two case :
The first case : every zone all can not be cooled!
You should check whether your water is cooling water . If the chiller don’t work ,water can not be cooled , the temperature of machine barrel with be higher and higher.
If water is cooling , but barrel also in high temperature.You should check the solenoid valve work or not .If the solenoid Valve are broken, change them and check again.
The second case: just one or two barrel can not be cooled
Also check the solenoid valve first, if working well, may be your barrel water channel is blocked. Just check , if barrel have blocked ,replace them .
When your water not clean, it will make the barrel blocked easily. So the water must be soft water.
Hope it can help you, if you have other problems of machine , please contact shelley, firstname.lastname@example.org.
