Dab tsi yog hom kev ua tsis tiav ntawm ib zaug -ntsia hlau extruder chim?

Hom tsis ua haujlwm feem ntau ntawm ib zaug - ntsia hlau extruder chim muaj xws li hnav, corrosion, kev tshem tawm ntau dhau, overheating thiab carbonization, thiab kev puas tsuaj los ntawm kev teeb tsa tsis raug.

Cov hom kev ua tsis tiav ntawm ib zaug - ntsia hlau extruder chim yog raws li hauv qab no:

1. Hnav tsis ua hauj lwm: Vim lub txiav cov nyhuv ntawm cov khoom polymer thiab cov neeg kho tshuab hnav ntawm cov tawv abrasive hais, qhov clearance ntawm lub puab phab ntsa ntawm lub thoob thiab cov ntsia hlau nto txuas ntxiv expands, yog li tsis muaj zog lub yaj plasticizing efficiency thiab deteriorating lub zoo sib xws ntawm cov khoom zoo.

2. Corrosion tsis ua hauj lwm: Nyob rau hauv siab - qhov kub thiab txias, pyrolysis ntawm raw cov ntaub ntawv generates acidic los yog oxidizing corrosive xov xwm, uas accumulates nyob rau hauv lub puab phab ntsa ntawm lub chim thiab induce electrochemical los yog tshuaj corrosion, accelerating cov khoom degradation txheej txheem.

3. Kev tshem tawm ntau dhau: Tom qab siv sijhawm ntev - siv sijhawm ntev, lub puab txoj kab uas hla ntawm lub thoob irreversibly expands, ua rau lub radial clearance nrog lub hau ntswj kom dhau lub tsim kam rau ua ntau yam, uas ua rau ib tug txo nyob rau hauv yaj conveying efficiency thiab ib tug tseem ceeb nce nyob rau hauv lub zog noj.

4. Thermally Induced Carbonization Failure: Kev ua haujlwm tsis zoo hauv cov cua txias lossis cov kev sib txhuam qhuav tuaj yeem ua rau qhov kub thiab txias hauv cheeb tsam nce siab tshaj cov khoom siv thermal stability, ua rau irreversible thermal decomposition thiab carbonization ablation ntawm matrix.

5. Kev sib dhos ua haujlwm tsis zoo: Deformation ntawm lub thoob axis, kev sib txawv ntau dhau ntawm coaxiality nrog cov ntsia hlau, los yog tsis sib xws ntawm flange preload tuaj yeem ua rau muaj qhov txawv txav ntawm kev sib cuag, uas ua rau nto khawb, txav mus los, thiab txawm tias cov khoom puas.
