Ua rau muaj kev ua haujlwm tsawg hauv Wood Chip Roj Pellet Machine thiab Yuav Ua Li Cas Kho Lawv
Pib nrog Feedstock, Tsis yog Lub Tshuab
Thaum cov zis poob rau ntawm cov ntoo chips roj pellet tshuab, thawj yam khoom los xyuas yog cov khoom siv raw, vim tias cov khoom noj khoom haus tsis zoo txo qhov peev xwm ncaj qha thiab tsis muaj lub tshuab teeb tsa tuaj yeem them rov qab rau nws. Ob yam khoom tseem ceeb tshaj plaws: cov ntsiab lus noo noo thiab particle loj faib. Cov khoom uas ntub dhau los yog qhuav dhau ua rau lub zog nias, thiab cov khoom siv hauv av loj dhau los yog qhov tsis sib xws ua rau cov khoom thauj ntawm lub zeb thiab txo cov khoom siv.
Kev kho yog ncaj nraim. Nqa cov dej noo mus rau qhov ua haujlwm ntawm li 12-15 feem pua, los ntawm kev ziab lossis los ntawm kev tswj cov ntub dej, thiab rov- tsoo thiab tshuaj ntsuam cov khoom kom cov khoom ntsuas kwv yees li 2-5 hli thiab muaj qhov loj me. Ib qho piv txwv zoo: tus tsim tawm khiav 1.2 t / h pom muaj peev xwm poob mus rau 0.8 t / h purely vim tias cov khoom noj khoom haus tau hloov pauv, thiab rov ua kom cov zis ib txwm muaj tom qab stabilizing noo noo. Kev kis kab mob tseem ceeb heev - rau tes, pob zeb thiab lwm cov khib nyiab ua kom hnav thiab txo cov khoom noj, yog li cov khoom noj yuav tsum tau tshuaj xyuas thiab khaws cia kom huv.
Ua rau 2: Hnav ntawm Xovxwm Rollers thiab Tuag
Hnav yog qhov laj thawj thib ob thiab qhov uas feem ntau tsis quav ntsej txog thaum muaj peev xwm tau poob qis heev. Ib tug hnav khaub ncaws saum npoo poob kev sib txhuam ntawm cov khoom thiab tsis tuaj yeem extrude nws zoo; loj los yog thaiv qhov tuag qhov qeeb ntawm cov pellets los ntawm qhov tuag. Ob qho kev cuam tshuam txo cov zis yam tsis muaj qhov ua txhaum cai.
Inspect the roller surface. If wear is uneven, grind it smooth; if wear exceeds 2 mm, replace the pressure roller.
Ntxuav qhov blocked tuag qhov ib tus zuj zus. Yog hais tias lub qhov yog hnav oversize, hloov cov tuag es tsis reaming lawv ntxiv.
Lubricate cov xovxwm rau cov menyuam bearings ntawm lub sijhawm muab los ntawm cov chaw tsim khoom kom txo qis kev hnav thiab txuas ntxiv lub neej kev pabcuam.
Tus cwj pwm tsim nyog hloov yog tos kom tsis muaj peev xwm loj ua ntej hloov qhov chaw. Kev tshuaj xyuas ntxov thiab kev hloov pauv kom lub tshuab ntawm nws cov txiaj ntsig tso tawm es tsis txhob cia kev ua haujlwm poob qis tsis tu ncua hla ib lub caij.
Ua rau 3: Tsis tsim nyog Parameter Chaw
Qhov thib peb ua rau zaum hauv qhov chaw tswj. Yog tias nias siab dhau lawm, cov khoom siv tsis yog extruded smoothly thiab cov throughput ntog; Yog hais tias cov menyuam ceev yog tsawg heev, tus naj npawb ntawm compressions ib chav tsev ntawm lub sij hawm poob thiab muaj peev xwm poob nrog nws. Parameter nqis yuav tsum ua raws li cov khoom noj.
| Cov khoom noj | Nias Siab | Roller Ceev |
|---|---|---|
| Hardwood chips | 13-15 MPa | 280-300 r / min |
| Softwood chips | 10-12 MPa | 250-280 r / min |
Hloov chaw maj mam thiab saib xyuas lub peev xwm tom qab txhua qhov kev hloov kho kom txog thaum lub tshuab mus txog nws qhov chaw ua haujlwm zoo tshaj plaws. Kev pub mis kuj yuav tsum tau muab sib npaug: yog tias qhov ceev ceev pub mis tsis txaus, lub tshuab nias tsis ua kom zoo, thiab kev txhawb nqa lub cev muaj zog yuav rov ua kom tsis tu ncua tab sis tsis muaj kev cuam tshuam ntawm cov khoom siv.
Ua rau 4: Lubrication tsis zoo
Lubrication yog ib qho yooj yim mus saib, vim hais tias nws cov nyhuv yog gradual. Lub lubrication tsis txaus ntawm cov xovxwm cov menyuam bearings thiab cov kab ke sib kis ua rau muaj kev sib txhuam tsis zoo, uas ua rau lub cev muaj zog thiab txo qis, thiab ob qho tib si txo cov zis. Kev kho yog lub sij hawm lubrication ruaj khov es tsis yog ib qho ad-hoc ib qho: siv siab- roj kub rau cov xovxwm cov menyuam bearings txhua 200 teev ua haujlwm, thiab hloov cov roj iav hauv lub reducer txhua 1000 teev ua haujlwm, siv cov roj nplua nyeem tau teev nyob rau hauv cov khoom siv phau ntawv.
Ua rau 5: Cov txheej txheem txheej txheem nyob ib ncig ntawm lub tshuab
Ob qho xwm txheej ntxiv tsim nyog tau txais kev kuaj xyuas thaum plaub qhov laj thawj saum toj no tau raug cais tawm. Ambient humidity nyob rau hauv ib qho chaw ua hauj lwm ntub dej cuam tshuam rau cov dej noo zoo ntawm cov khoom siv hauv av thiab tuaj yeem thawb tawm sab nraud ntawm 12-15 feem pua txawm tias lub tshuab ziab khaub ncaws raug teeb tsa kom raug. Voltage poob los yog ib qho undersized mov cable tseem yuav rub rotor ceev nyob rau hauv load, uas zoo nkaus li zoo li ib tug txhua yam muaj peev xwm poob. Yog hais tias tus tsav yog lubricated kom raug, cov tuag thiab cov chais yog nyob rau hauv qhov zoo thiab tsis haum rau feedstock, cov lwm yam sab nraud yog cov neeg sib tw.
Diagnostic Order Uas Txuag Sijhawm
Ua haujlwm nyob rau hauv kev txiav txim feedstock, hnav qhov chaw, chaw, lubrication, ces txheej txheem tej yam kev mob. Feedstock yog cov khoom ceev tshaj plaws rau kev sim, vim tias noo noo tuaj yeem ntsuas los ntawm qhov cub txoj kev ntawm ISO 18134-2 thiab particle loj faib los ntawm txoj kev sieving ntawm ISO 17827-2. Cov khoom hnav yuav tsum tau kuaj xyuas lub cev. Kev teeb tsa xav tau kev sim ntawm ob lub ntsiab lus ua haujlwm. Ua raws li qhov kev txiav txim no zam qhov ua yuam kev ntau ntawm kev kho lub tshuab kom them nyiaj rau cov khoom siv raw uas yuav tsum tau kho ntawm qhov tau txais.
Cov lus nug nquag
Q:Cov dej noo dab tsi yuav tsum tau ntoo chip feedstock muaj ua ntej pelletizing?
A: Kwv yees li 12-15 feem pua yog qhov ua haujlwm ntau rau cov xovxwm. Saum toj no los yog hauv qab uas qhov kev txiav txim siab qeeb qeeb thiab cov zis poob, yog li cov dej noo yuav tsum raug kho los ntawm kev ziab lossis los ntawm kev tswj kom ntub dej ua ntej cov khoom nkag mus rau hauv lub zeb.
Q:Qhov luaj li cas ntawm cov khoom siv hauv av yuav tsum muaj?
A: Nyob nruab nrab ntawm li 2 hli thiab 5 hli, nrog rau ib qho kev faib tawm. Oversize los yog unevenly av cov ntaub ntawv tsub kom lub load ntawm lub tshuab thiab txo lub peev xwm txawm tias thaum noo noo yog lawm.
Q:Thaum twg yuav tsum tau hloov lub siab roller?
A: Yog tias hnav tsis sib xws nws tuaj yeem ua rau hauv av du. Thaum hnav ntau dua 2 hli, cov menyuam yuav tsum tau hloov, vim tias qhov hnav tsis tuaj yeem tuav thiab extrude cov khoom zoo.
Q:Lub sijhawm lubrication twg siv rau cov xovxwm cov menyuam bearings?
A: Siab-cov roj kub yuav tsum tau ntxiv rau cov xovxwm cov menyuam bearings txhua 200 teev ua haujlwm, thiab cov roj reducer yuav tsum tau hloov txhua 1000 teev ua haujlwm, siv cov roj nplua nyeem tau teev tseg hauv phau ntawv.
Q:Lub siab thiab nrawm npaum li cas rau cov tawv ntoo thiab cov ntoo mos?
A: Rau hardwood chips, 13-15 MPa ntawm 280-300 r / min. Rau softwood chips, 10-12 MPa ntawm 250-280 r / min. Kho maj mam thiab xyuas lub peev xwm tom qab txhua qhov kev hloov pauv.
Q:Vim li cas lub peev xwm poob txawm tias tsis muaj feem ua tsis tiav?
A: Vim tias hnav thiab ya raws drift txo cov zis maj mam. Cov menyuam hnav tsis sib xws, qee qhov thaiv qhov tuag qhov, tsis txaus lubrication thiab hloov pauv cov khoom noj khoom haus kom txo tau lub peev xwm yam tsis muaj kev puas tsuaj, uas yog vim li cas teem sijhawm kuaj xyuas tos kom pom qhov txhaum.
