Floating ntses pub pellet ua tshuab clogging thaum pib yog ib qho teeb meem uas tuaj yeem cuam tshuam cov txheej txheem tsim khoom, nkim sij hawm, khoom siv, thiab cov peev txheej. Qhov teeb meem no yog teeb meem tshwj xeeb rau cov neeg ua haujlwm tshiab. Los ntawm kev nkag siab txog qhov tshwm sim, ua rau, thiab kho sai, cov neeg ua haujlwm tuaj yeem txo qis qis thiab ua kom lub tshuab ua haujlwm zoo txij thaum pib.

I. Cov Phenomena tshwj xeeb ntawm Extruder Clogs Thaum Pib Pib-nce
Phenomenon Description:
Tom qab preheating, cov khoom siv raw yog pub rau hauv, thiab lub tshuab zoo li ua haujlwm ib txwm, tab sis:
- Tsis muaj cov khoom pov tseglos ntawm qhov tuag los yog tsuas yog qhov tsawg kawg nkaus yog cov zis.
- Cov ntaub ntawv rov qabthiab cov pa tawm tuaj yeem tshwm sim ntawm qhov nkag nkag.
- Muaj ibme ntsis burnt tswlos yogsuab nrov txawv txavlos ntawm lub tshuab chamber.
- Covmain unit tam sim no spikes(feem ntau yog tshaj 1.2 npaug ntawm qhov ntsuas tam sim no), ua rau qee lub tshuab ua rau muaj kev cuam tshuamkev tiv thaiv overloadthiab kaw cia li.
- Tom qab disassembly,khoom clumpingthiabthaivmuaj nyob rau hauv lub tshuab chamber, tuag, thiab ntsia hlau nto, raws li zoo raws li ungelatinized raw khoom.
Cov phenomena no feem ntau pom tom qab:
- Khoom sivdebugging.
- Cov khoom siv raw hloov.
- Rov pib duatom qab lub sij hawm ntev ntawm inactivity.
II. Cov laj thawj tseem ceeb ntawm lub tshuab thaiv thaum pib pib-up
1. Tsis txaus Preheating ntawm Milling Chamber
- Ua rau: Tsis ua raws li cov txheej txheem preheating tau pom zoo, lossis lub sijhawm ua ntej tsis txaus (tsawg dua 20 feeb) ua rau lub chamber kub tsis ncav cuag.yam tsawg kawg yuav tsum tau kub(siab tshaj 140 degree).
- Qhov tshwm sim: Cov khoom siv raw tsis tas lisoftenedthiabgelatinized, ua rau lawv ntws tsis zoo thiab nquag musclumpingthiabagglomeration, uas ua rautuag orificethaiv.
- Kev cuam tshuam: Qhov no yog feem ntau ua rau blockages, accounting rau52% ntawm cov neeg mob.
2. Raw Material Parameters tsis ua raws li qhov yuav tsum tau ua
- Moisture Content Tsawg dhau: Yog tias cov ntsiab lus noo noo yogqis dua 12%, raw cov ntaub ntawv yog heevqhuav, ua rau lawv nyuaj rau khi thiab ua raustagnationthiabclumping.
- Teeb meem Particle Size: Yog hais tias qhov particle loj dhau lawmlojlos yogtsis sib xws, nws tshaj qhov tuag qhov loj me, tiv thaiv cov ntaub ntawv du thiab ua rau blockages.
- Cov khoom txawv teb chaws: Hlau tawg, pob zeb, thiab lwm yam khib nyiab hauv cov ntaub ntawv raw tuaj yeem ncaj qhajam lub haulos yogthaiv qhov chaw tuag, ua rau muaj kev cuam tshuam.
3. Pib tsis tsim nyog-Kev Ua Haujlwm
Ua rau: Tsis ua haujlwm atsis muaj -load testkhiav ua ntej noj cov khoom nyoos.
Qhov tshwm sim:
- Sudden cov khoom tsub zuj zujnyob rau hauv lub tshuab chamber.
- Ntsia hlau ceev tsis maj nce, ua rau tam sim ntawdclogging.
- Pub ceev ceev heev, overwhelming lub tshuab pib ua lub peev xwm.
- Tsis muaj cov khoom siv thawj zaug(xws li cov hmoov nplej siav) ua raustagnation.
4. Cov Khoom Siv Hluav Taws Xob Cov Khoom Siv Hluav Taws Xob lossis Cov Teeb Meem Hnav
- Tuag Lub Taub Hau lossis Distributor Plate Installation: Kev teeb tsa tsis raug lossis kev teeb tsa tsis raug tuaj yeem cuam tshuam cov khoom ntws.
- Screw thiab Screw Tes Tsho Hnav: Kev hnav hnyav txo cov ntsia hlauthawb lub peev xwm, tiv thaiv cov khoom los ntawm kev raug thawb mus rau qhov tuag.
- Tuag taub hau txiv ntseej Installation: Kev teeb tsa tsis raug tuaj yeem ua rau cov ntsia hlau tuav, thaiv kev ua haujlwm ib txwm muaj.
III. Kev Tiv Thaiv Thaum Muaj Xwm Ceev thiab Kev Tiv Thaiv Kev Tiv Thaiv Kev Tiv Thaiv thaum pib- nce
Cov kauj ruam thaum muaj xwm ceev (Safety First):
- Tam sim ntawd nres lub tshuabthiabdisconnect lub zogtiv thaiv kev puas tsuaj ntxiv.
- Kaw lub qhov cub valvetxhawm rau tiv thaiv cov pa tawm thiab kub hnyiab los ntawm cov ntaub ntawv kub -.
- Hnav cov khoom tiv thaivxws lisiab -cov hnab looj tes kubthiabdaim npog qhov ncauj tiv thaiv.
- Disassemble lub taub hau tuag thiab ntws divider, ces ntxuav tawm lubthaiv cov khoomthiabcov khoom txawv teb chaws.
- Maj mam ntxuav cov pobsab hauv lub tshuab chamber los ntawm cua sov thiab gelatinizing lawv.
- Txheeb xyuas cov ntsia hlau thiab core installationthiab kho kom raug txoj hauj lwm.
- Reinstall lub taub hau tuag thiab ntws divider, xyuas kom txhua yam yogruaj ntseg zoo.
Standardized Pib-txheej txheej txheem:
- Preheat lub tshuab chamber:
- Xyuas kom qhov kub ncav cuag150-180 degreerauyam tsawg kawg 20 feeb.
- Saib xyuas qhov kub thiab txias hauv lub sijhawm tiag - siv akub tswj.
- Khiav lub tshuab tsis muaj -loadrau3-5 feebkom paub meej tias cov ntsia hlau du ua haujlwm.
- Maj mam nce ntsia hlau ceevib zaug cov tuag yog tawm cov khoom ib txwm.
- Tsis txhob pub khoom noj tam sim ntawdtiv thaiv kev sib sau.
Raw Material Control Measures:
- Screen raw khoomua ntej noj kom tshem tawm cov teeb meem txawv teb chaws (xws li, pob zeb, hlau tawg).
- Kho cov dej noo: Lub hom phiaj rau qhov zoo tshaj plaws ntawm12-15%.
- Tsawg noo nootuaj yeem hloov kho los ntawm txau dej thiab nplawm tusyees.
- Xyuas kom zoo ib yam particle loj(20-40 mesh) los txhawb kev ntws thiab gelatinization.
Ua ntej-Kev soj ntsuam cov cuab yeej ua haujlwm:
- Txheeb xyuas cov khoom siv installation:
- Xyuas kom covtuag taub hau, flow divider, ntsia hlau, thiabtub ntxhaisyog raug raws nraim thiab ruaj ntseg.
- Tshawb xyuas cov ntsia hlau thiab threaded tes tsho hnav:
- Hloov yog hnav, raws li cov khoom hnav cuam tshuam cov khoom txav thiab ua rau muaj kev pheej hmoo clogging.
- Ntxuav cov khoom seemlos ntawm qhov tuag qhov thiab tso tawm channel los tiv thaiv cov blockages.
- Xyuas kom tsis muaj kev cuam tshuamnyob rau hauv lub taub hau tuag los yog manifold feed qhov.
