How To Maintain The Screw Extruder?

The following are some tips for maintaining the screw extruder:

1. Daily maintenance:

- Clean the machine: keep the surface of the extruder clean and free of dirt regularly clean the hopper and screw to prevent foreign matter from entering. Lubrication of moving parts: regularly check and lubricate screw, bearing and other moving parts to maintain good lubrication and reduce wear.

- Fastening loose thread parts: check and tighten screw 1 frequently

Nails, nuts and other fasteners to prevent equipment failure due to loosening,

- Check the control instrument: ensure the normal operation of the temperature control instrument, sensitive and reliable.

2. Regular maintenance:

- Regular inspection: Every 2500-5000 hours of operation, a comprehensive inspection of the extruder should be carried out to measure and identify the wear of the main parts, and replace the wear parts in time.

- Screw cleaning: Use special cleaning agent to clean the screw regularly, remove carbon deposits and impurities, and keep the screw surface clean.

- Change the lubricating oil: change the reducer lubricating oil regularly, and clean the fuel tank and filter to keep the oil clean.

- Check the heating and cooling system: check the heater and cooling water pipes to ensure that the temperature control is stable and there is no blockage and leakage.

In addition, in the maintenance of the screw extruder, should also pay attention to the following points

- Keep the production environment clean, do not mix garbage impurities into the material cold blocking filter plate, affect the output and quality of products.

- Prevent metal or other debris from falling into the hopper, so as not to damage the screw and barrel. Magnetic suction parts or magnetic racks can be installed at the hopper mouth to prevent debris from falling into.

- When the screw and barrel are not used for a long time, they should be coated with anti-rust grease and suspended to avoid deformation or damage.

In short, regular maintenance and maintenance of the screw extruder can ensure the efficient operation of the equipment and the stable quality of the product.
