What to do if there is a sudden power outage while the wood plastic extruder is running?
If there is a sudden power outage during the operation of the wood plastic extruder, follow the steps below:
1. Turn off the relevant power switch immediately:
- Cut off the main switch of the extruder to prevent the extruder from accidentally starting when the power is suddenly on, causing safety accidents or equipment damage.
- Set each speed knob back to zero, turn off the electric heating and feeding system switches to reduce unnecessary energy consumption and potential dangers.
2. Clean or discharge the material (depending on the situation):
- If the power outage time is short (such as it is expected that the power supply can be restored within half an hour), and you do not want to disassemble the mold and other parts, you can try to manually turn the belt or use a rocker to manually turn the extruder motor, and try to discharge the material inside the extruder to minimize the residue in the barrel. This can prevent the material from staying in the barrel for a long time at high temperature and degrading or coking.
- If the power outage time is long or it is uncertain when the power will be on, in order to prevent the material from deteriorating and curing in the barrel and being difficult to clean, the die, confluence core and other parts should be disassembled in time, and the turner should be used to slowly turn the turner, and the cleaning material should be added through the exhaust hole to replace the production material outside the machine.
3. Strengthen cooling measures (if necessary):
If the main motor of the extruder is directly connected to the gearbox and there is no device to rotate the motor with a rocker, the cooling water of the cooling system can be increased to quickly cool down the temperature of the extruder barrel and screw to prevent the material in the extruder from plasticizing, sticking or aging.
4. Keep records and communicate:
record the time of the power outage, the operating status of the extruder at that time, the operations taken, and other information for subsequent analysis and processing. At the same time, communicate the power outage with relevant departments or personnel in a timely manner to coordinate subsequent production arrangements and equipment maintenance work.
When the power supply is restored, do not rush to start the extruder. You should first check whether the various parts of the equipment are normal, whether the temperature of the barrel and the die head mold is within the process temperature range, etc. After confirming that there is no abnormality, follow the normal startup steps.
