简体中文The screw and barrel in an extruder can face a variety of common failures, including screw breakage, corrosion within the barrel, screw wear, barrel overheating, screw expansion, increased screw and barrel clearance, motor failure, and extruded materials Accumulation etc. These failures may be caused by factors such as excessive load, wear, chemical corrosion, high temperature and high pressure.
In order to maintain the normal operation of the extruder, corresponding maintenance methods need to be adopted. First of all, regularly check the wear status of the screw and use appropriate extrusion materials to prevent the screw from breaking or excessive wear. Secondly, the barrel is made of corrosion-resistant materials, the inside of the barrel is regularly cleaned, and a corrosion protective coating is applied to prevent corrosion inside the barrel. For screw wear, the degree of wear needs to be checked regularly and repaired or replaced if necessary.
Controlling the barrel temperature is an important means to prevent overheating, ensure the normal operation of the temperature control system, and check the cooling system regularly. Measures to prevent screw expansion include using a suitable cooling system, regularly checking screw operating status, and ensuring appropriate expansion clearance. Maintaining an appropriate gap between the screw and barrel requires regular inspection and adjustment according to production needs.
For motor failures, operators should regularly check motor operation, cable connections, and cooling systems. The accumulation of extruded material may affect production efficiency, so the extruded material residue in the barrel needs to be cleaned regularly.
