Lub tshuab pellet yog ib qho khoom siv rau compressing biomass pellet roj thiab pellet pub, ntawm lub siab uas cov menyuam nyob yog nws qhov chaw siab thiab qhov yooj yim. Vim nws cov haujlwm hnyav thiab ua haujlwm hnyav, txawm tias muaj kev ua tau zoo, hnav thiab kua muag yog kev tsis taus. Hauv cov txheej txheem ntau lawm, kev noj ntawm cov chais tau muaj siab, yog li cov khoom siv ntawm lub siab rollers yog tshwj xeeb.
Kev ntsuas tsis tau ntawm lub siab cov menyuam ntawm lub tshuab particle
Cov txheej txheem ntau lawm ntawm cov menyuam siab suav nrog: kev quav ntsej, ntxhib machining, queming thiab tempering machining, nto quenching, thiab precision machining. Ib pab neeg tshaj lij tau pib kev sim ntawm kev coj ua ntawm biomass pellet ruels rau kev tsim khoom thiab kev xaiv lub meej mom ntawm cov khoom siv thiab cov txheej txheem kho cua sov. Cov hauv qab no yog cov kev tshawb nrhiav cov lus xaus thiab cov lus pom zoo:
Dents thiab khawb tshwm saum npoo ntawm lub siab uas cov neeg uas cov neeg nyiam ntawm cov granulator. Vim tias hnav cov impurities zoo xws li cov xuab zeb thiab hlau cov ntawv tso rau ntawm lub siab rau ntawm lub siab, nws belongs rau kev hnav khaub ncaws txawv. Qhov nruab nrab nplaim taws yog li 3mm, thiab kev hnav ob sab sib txawv. Cov seem pub muaj hnyav, nrog kev hnav khaub ncaws ntawm 4.2mm. Feem ntau vim yog qhov tseeb tias tom qab pub mis, lub homogenizer tsis muaj sijhawm so kom tau faib cov khoom thiab nkag mus rau qhov kev sib tw.
Cov me me hnav ua tsis tiav tsom xam tau tias vim muaj axial hnav nyob rau saum npoo ntawm cov khoom siv raw, cov tsis muaj cov khoom siv ntawm lub siab yog qhov ua tsis tau. Lub ntsiab ntawm cov hnav yog nplaum hnav thiab abrasive hnav, nrog cov pits, thaiv cov khoom sib dhos, thiab lwm yam. Vim qhov kev ua ntawm cov dej vapor thiab lwm yam, av zoo li cov qauv ntawm cov menyuam yaus, ua rau muaj kev ntxhov siab rau saum npoo ntawm lub siab.
Nws raug nquahu kom ntxiv ib tus kab mob raug tshem tawm ua ntej tsoo cov ntaub ntawv nyoos, txhawm rau tiv thaiv cov ris tsho sib xyaw thiab kua muag ntawm lub siab chais. Hloov cov duab lossis kev teeb tsa txoj haujlwm ntawm tus txha hniav faib cov ntaub ntawv hauv lub siab compression ntawm lub siab thiab exacerbating hnav rau saum npoo ntawm lub siab cov menyuam. Vim tias qhov tseeb tias lub siab uas cov menyuam yaus tsis yog vim muaj cov txheej txheem nto, thiab corrosion tsis kam, cov txheej txheem kev kho mob siab thiab cov txheej txheem kev kho cua kub tsim nyog.
Cov khoom siv thiab txheej txheem kho kev kho mob ntawm lub zog chais
Cov khoom siv muaj pes tsawg leeg thiab cov txheej txheem ntawm lub siab cov menyuam yog qhov ua ntej rau kev txiav txim siab nws cov coj tsis kam. Cov khoom siv uas siv tau siv xws li C50, 20crmnti, thiab GCR15. Kev tsim cov txheej txheem siv cnc tshuab cov cuab yeej siv cnc tshuab, thiab cov menyuam cov menyuam tuaj yeem raug kho nrog cov hniav ncaj, oblique hniav, hom txav, thiab lwm yam raws li cov kev xav tau. Kev kho mob carburization quenching lossis siab zaus quenching cua sov yog siv los txo cov menyuam yaus deformation. Tom qab kev kho cua sov, ntsuas hluav taws xob yog ua kom paub meej ntxiv kom ntseeg tau tias lub voj sab hauv thiab sab nraud, uas tuaj yeem nthuav tawm lub neej ntawm cov menyuam.
Qhov tseem ceeb ntawm kev kho cua sov rau lub siab chais
Cov kev ua tau zoo ntawm lub siab cov menyuam yuav tsum ua kom tau raws li cov kev xav tau ntawm lub zog siab, thiab siab zoo li zoo machinishity (suav nrog zoo polishing) thiab corrosion tsis kam. Kev kho cua sov ntawm lub siab rollers yog ib qho txheej txheem tseem ceeb taw ntawm kev tsis muaj peev xwm ntawm cov ntaub ntawv thiab txhim kho lawv cov kev ua tau zoo. Nws muaj qhov cuam tshuam ncaj qha rau kev tsim khoom raug, lub zog, kev pabcuam lub neej, thiab cov nqi tsim khoom.
Rau tib cov ntaub ntawv, cov ntaub ntawv uas muaj undergone overheating kev kho mob muaj ntau dua lub zog, hardness, thiab ruaj khov piv rau cov khoom uas tsis tau txhim kho kev kho mob dhau los. Yog tias tsis quenched, kev pabcuam lub neej ntawm lub siab cov menyuam yuav tau luv dua.
Yog tias koj xav paub qhov txawv ntawm kev kho cua sov thiab tsis muaj cua sov-kho uas tau ua kom pom qhov txawv ntawm lub zog thiab kev kho mob kub oxidation xim. Yog tias koj tsis xav txiav thiab kuaj, koj tuaj yeem sim cais lawv los ntawm tapping suab. Daim duab hlau thiab kev sib txhuam sab hauv ntawm cov cuab yeej thiab quenched thiab tempered workpieces sib txawv, thiab tuaj yeem sib txawv los ntawm cov tapping maj.
Lub hardness ntawm kev kho cua sov yog txiav txim los ntawm ntau yam, suav nrog cov qib qib, qhov loj me, ua haujlwm thiab qauv kev ua haujlwm. Piv txwv li, thaum siv xov huab cua ua kom loj, vim tias qhov tseeb tuab ntawm lub zog ua haujlwm tau tuaj yeem ncav cuag kev ua ke nrog cov haujlwm ua haujlwm. Ib qho ntxiv, tsis tsim nyog nyuaj nyuaj cov ntsiab lus, xws li nyuaj heev nyuaj, tuaj yeem ua rau poob ntawm kev ua haujlwm thiab ua rau tawg thaum siv.
Kev kho cua sov yuav tsum tsis tsuas yog ua kom muaj txiaj ntsig tsim nyog, tab sis kuj them nyiaj rau nws cov txheej txheem xaiv thiab txheej txheem tswj. Overheated quenching thiab tempering tuaj yeem ua tiav qhov kev xav tau zoo; Ib yam li ntawd, nyob rau hauv cov cua sov thaum lub sij hawm quenching, kho qhov kub siab kuj tseem tuaj yeem ntsib cov hardness.
Lub booter siab cov menyuam yog tsim los ntawm cov tawv nqaij zoo thiab hnav tsis kam ntawm cov particle tshuab siab cov menyuam los ntawm qhov chaw. Ua ke nrog exquisite high-kub quenching tshav kub kho tshuab, nws tau ntev ntev nws txoj kev pabcuam lub neej.
