Extruders Supporting the operation and maintenance

Plastic extruder production in the maintenance is an extremely important task, maintenance can improve the life of the machine, it should be with the matching operation and maintenance and other closely with the full-time staff should be on duty inspection. The same time as

1, the oil injected into the machine must be clean, the seal must be good, the machine's main oil filling

(1) Rotary bearings (2) Roller bearings (3) All gears (4) Movable bearings, sliding surfaces. The same time as

2, the new installation of the wheel prone to loose must be regularly checked. The same time as

3, pay attention to the work of the various parts of the machine is normal. The same time as

4, pay attention to check the wear and tear of the wear and tear, pay attention to replace the wear parts. The same time as

5, put the activities of the chassis plane, should be out of dust and other objects in order to avoid the machine can not break the material when the activities of the bearings can not move on the chassis, resulting in serious accidents. The same time as

6, bearing oil temperature rise, should immediately stop the cause of the check to be eliminated. The same time as

7, rotating gear in the operation if the impact should immediately stop inspection. The same time as

 Always pay attention to plastic extrusion body temperature changes, with a clean hand touch the sliver does not stick, it should immediately heat up. Until the sliver is normal. Reducer bearing parts burned, or accompanied by noise should be timely maintenance, and add fuel. Host bearing at both ends of the bearing parts of the hot hand or noise, to stop maintenance and add butter. Normal work, the bearing room every 5-6 days plus butter once. Fuselage operation is unstable, should pay attention to check the coupling is not too tight gap,

  The control effect of the plastic extruder barrel is not always the same as expected, especially in the measurement area? If the barrel is heated, the viscosity of the material layer at the tube wall becomes smaller and the motor needs less energy to operate in this smoother barrel. Motor current (amperes) drops. Conversely, if the barrel cools, the melt viscosity at the barrel wall increases, the motor must rotate more forcefully, the amperage increases, and some heat removed through the cartridge is returned by the motor. In general, the barrel regulator does have an effect on the melt, which is what we expect, but the effect of any place is no regional variable. It is best to measure the melt temperature to really understand what happened.
