Common Rubber Extruder Failures

Common rubber extruder failures:

1. The starting current of the main motor is too large


(1) The heating time is insufficient and the torque is large. (2) Some parts of the heater do not work.


(1) Please use the handwheel when driving. If it's not easy, extend the heating time or check that every part of the heater is working properly.

2. The main motor cannot be started


(1) There is an error in the startup program. (2) There is a problem with the main thread of the motor and whether the fuse is burnt. (3) Interlocking device work related to the main motor


(1) Check the program and restart the car in the correct driving sequence. (2) Check the main motor circuit. (3) Check whether the lubricating oil pump has been started, and check the status of the interlocking device related to the main motor. The oil pump won't turn on, and the motor won't turn on either. (4) Check whether the emergency button is reset. (5) The induced current of the inverter has not been released, please turn off the main power supply and wait for 5 minutes before starting it.

3. The host current is unstable


(1) The power supply is uneven. (2) The main motor bearing is damaged or poorly lubricated. (3) A part of the heater fails and does not heat. (4) The screw adjustment pad is wrong or the phase is wrong, and the components interfere.
