1. The screw is not working properly.
Reason: the hopper feed is not continuous; The feed port is blocked or bridged with foreign matter; Hard metal objects fall into the thread, blocking the thread, unable to feed normally.
Treatment methods: to accelerate the feed rate of PFA extruder and maintain the feed stability; Remove foreign matter from inlet and remove bridge phenomenon; Make sure that the metal foreign body falls into the spiral groove, stop the machine immediately to remove the spiral and remove the metal foreign body.
2. The vent is blocked.
Cause: Due to the unstable screw extrusion, the plasticization temperature is not enough, and there are a lot of impurities in the PFA raw material, resulting in the PFA tube extruder feed too fast.
Treatment method: clean or replace the filter before PFA feeding; Reduce the feed rate to make the plasticizing stabilized screw stable extrusion; Increase the plasticizing temperature of PFA extruder.
3. The host does not rotate or stops instantaneously.
Cause: PFA tube extruder main motor power supply is not connected; Insufficient heating time, or one of the heaters does not work, resulting in excessive motor torque, overload.
Treatment method: Check whether the main circuit of PFA pipeline extruder is through. Check the temperature display of each part, determine the machine preheating time, check whether the heater is damaged or bad contact.
