The twin screw extruder is developed on the basis of the single screw extruder. Due to its good feeding performance, mixing and plasticizing performance, exhaust performance, extrusion stability, and other characteristics, it has been widely used in the forming process of extrusion products. The twin screw extruder is composed of several parts, such as a transmission device, a feeding device, a barrel, and a screw. The functions of each component are similar to those of a single screw extruder. The difference with the single screw extruder is that the twin screw extruder has two parallel screws placed in the "co" shaped section of the barrel.
Reason 1: the start-up procedure is wrong.
Solution: check the procedure and start the machine in the correct start-up order.
Reason 2: there is a problem with the motor thread. Check whether the fuse is burned out.
Solution: check the main motor circuit of the dual screw extruder. Check whether the lubricating oil pump is started, and check the status of the interlocking equipment related to the main motor. If the induction power of the frequency converter has not been discharged, turn off the main power supply and wait for 5 minutes before starting it. Check to see if the emergency button is reset.
Reason 1: the main motor bearing is damaged.
Solution: replace the main motor bearing.
Reason 2: a certain thyristor in the thyristor rectifier circuit of the main motor of the twin screw extruder is damaged. Polyethylene wax, polyethylene wax manufacturer, oxidized polyethylene.
Solution: check the thyristor rectifier circuit, and replace the thyristor component if necessary.
Reason 1: uneven feeding.
Solution: check the feeder and eliminate the fault.
Reason 2: the main motor bearing of the dual screw extruder is damaged or poorly smooth.
Solution: overhaul the main motor and replace the bearing if necessary.
Reason 3: a certain section of the heater fails and does not heat.
Solution: check whether each heater is working normally, and replace the heater if necessary.
