Screw removed, cleaning, installation methods：
A,Screw removed
Remove the screw must used the specialized tools(provided by the sellers), equipped with the tool is in order to succeed in extruder screw directly after emptying disassemble, at this time, yet, so the residual melt condensation screw easily be ejection. If extruder has cooled, ejector screw before getting through to heating zone and heated to the operating temperature, then again disconnect the power supply. Ejection shall, before the supporting lifting equipments, so in the ejection when supporting screw
Remove screw before, should first conveying rate of flow, ex-changer device, metering pump and mould etc, ensure that the demolition screw extruder barrel can pull out easyly.
remove special nuts under screwed remove special handle, clockwise mandrels, until screw ejection reducer output shaft within hole so far. Finally, can pull out screw, put in clean, soft materials.
B,Screw install
Before installation, eliminate screw surface and barrel inner hole , transmission shaft within hole. Then, sleeve inner hole coated with a thin layer of silicon oil, screw shaft coated with silicon grease. Before installation, feeding port must cover, suggested that the extruder heated to the operating temperature, so it is easy to install.
When installed, will screw shaft keys with output shaft of reducer inner hole, and carefully keyway alignment will screw pushed into a barrel, until the screw in place so far, or using screw installation specialized tools, will be installed spindle screwed screw after termination of screw holes, turn the nut can load screw. Screw should have been pushed to resist date, depending on the size chart can check screw whether put in position.
Note: when installing screw process, can never using powerful, lest damage button and the keyway. If the key is too tight, should give careful correction.
C,Screw and barrel's cleaning
Should use yellow wire brush, brass aluminium or copper regiment scraper, or cleaning screw, avoid bruising screw.
Extrusion machine machine in the cylinder holes should be in one-dimenion thermal cleaning, cleaning with a diameter of fixed accords with within the bars of semicircle scraper, first will scraper up insert barrel, then scraper semicircle face downwards, will the remnants of the melt scratched away, when necessary, the process repeats itself, finally prepared by using diameter or copper brass brush brush will sleeve brush clean.
