Kuv Yuav Kho Cov Chip Loj Li Cas Rau Ib Nruas -style Ntoo Chipper?

Nruas chippers yog cov neeg ua haujlwm ntawm cov chaw ua haujlwm, tig cov ceg ntoo, cov ceg ntoo, thiab cov ntoo tag nrho rau hauv cov khoom sib xws rau mulch, biomass, lossis pov tseg.Ib qho ntawm cov lus nug ntau tus neeg teb xov tooj nug yog: "Kuv yuav hloov qhov luaj li cas ntawm cov chips?" Ntawm lub nruas-style chipper, nti loj tsis yog tswj los ntawm ib qho kev sib txuas ntawm ob peb qhov kev teeb tsa. kev hloov pauv thiab paub yuav kho lawv li cas kom nyab xeeb yuav pab koj tau txais cov nti loj koj cov neeg siv khoom (lossis koj lub boiler, lossis koj cov mulch pawg) xav tau.
Hauv qab no yog cov tswv yim, kauj ruam - los ntawm - cov lus qhia kauj ruam tsom rau cov tswv, cov neeg ua haujlwm, thiab cov tshuab tshuab nkoj.
1.Dab tsi tiag txiav txim siab Chip Loj?
Ntawm lub nruas chipper, chips yog tsim thaum lub nruas tig -nruab riam cheb dhau lub txaj txaj txaj (txhaj sab) thiab txiav tawm ib feem ntawm cov ntoo xa los ntawm cov khoom noj khoom noj.Cov ntsiab lus tseem ceeb yog:
Factor Yuav ua li cas nws cuam tshuam rau nti loj
Riam-rau- txaj- riam clearance Me me clearance= thinner chips; loj dua clearance= thicker chips.Qhov no yog lub ntsiab hloov kho.
Riam txuas ntxiv (txoj hauj lwm radial) Pushing riam tawm sab nraud ntawm lub nruas nce qhov tom; retracting nws txo cov nti tuab.
Feed roller speed vs.drum speed Slower feed relative to nruas RPM=shorter chips; fast feed=long chips.Muaj ntau lub tshuab muaj qhov sib txawv -speed feed controller.
Cov riam ntawm lub nruas Ntau rab riam ib kiv puag ncig= luv dua (txhua riam yuav siv me me tom).
Ntoo hom & noo noo Hard, qhuav ntoo nyhav tsim kom huv si, zoo ib yam chips; ntub los yog twisted grain yuav txawv me me txawm nrog zoo chaw.
Feem ntau hnub-rau-hnub hloov kho tsom rau kev tshem tawm thiab riam txoj hauj lwm, nrog rau kev pub ceev raws li qib thib ob.
2.Ua ntej koj kov txhua yam: Kev nyab xeeb ua ntej
Lub nruas chipper yog unforgiving.Ib txwm ua raws li lockout/tagout:
1. Kaw lub cav thiab tshem tawm tus yuam sij.
2.Ua qhov chaw nres tsheb thaum muaj xwm ceev yog tias nruab.
3.Relieve hydraulic siab ntawm lub feed system (lub voj voog lub zog pub ob peb zaug nrog lub twj tso kua mis tawm, lossis ua raws li koj phau ntawv txheej txheem los ntshav).
4. Muab lub tshuab tso rau hauv "hom tu" / ntxig lub kaw lus ntawm lub roj teeb cais thiab roj solenoid.
5. Tos kom lub nruas los ua kom tiav -tsis txhob cia siab rau tus nres ib leeg; xyuas lub cev los ntawm kev sim tig lub nruas los ntawm tes (tom qab loosening ib txoj siv sia yog siv tau).
⚠️Tsis txhob ncav mus rau hauv lub chute lossis ze ntawm lub txaj txaj thaum lub nruas tseem tuaj yeem tig.Txawm tias ib zaug khaws cia - lub zog kiv puag ncig tuaj yeem ua rau raug mob hnyav.
3. Nrhiav cov ntsiab lus hloov kho
Txhua qhov chaw tsim khoom (Bandit, Vermeer, Morbark, Peterson, thiab lwm yam) muaj nws tus kheej layout, tab sis cov ntsiab lus zoo sib xws:
•Bed- Riam hloov bolts-Feem ntau ob los yog peb bolts tom qab lub anvil uas txav tag nrho cov txaj txaj rau pem hauv ntej / rov qab txheeb ze rau lub nruas.
• Riam-mount shims–Lub nruas riam yog mounted ntawm blocks los yog hnab tshos nrog shims nyob rau hauv qab.Ntxiv shims thawb riam tawm sab nraud; tshem lawv rub nws rov qab.
• Pub-Cov menyuam tswj ceev-Ntau zaus hu lossis digital teeb tsa ntawm lub vaj huam sib luag tswj (nws txawv ntawm hydraulic ntws mus rau lub tshuab pub).
Tshawb xyuas koj tus neeg teb xov tooj phau ntawv qhia txog qhov chaw thiab lub zog torque specs -lawv tseem ceeb.
4.Step-los ntawm-Step: Kho Chip Size (Primary Method– Riam/Bed Clearance)
Kauj Ruam 1: Ntsuas qhov kev tshem tawm tam sim no
Siv lub ntsuas ntsuas ntawm qhov nruab nrab ntawm rab riam (tsis yog lub hau, tsis yog pob taws). Cov kev tshem tawm ntawm ntau lub nruas chippers yog 0.010 "-0.030" (0.25-0.75 mm), tab sis kos koj phau ntawv. Sau tus lej kom koj paub tias koj pib nrog dab tsi.
Kauj Ruam 2: Txiav txim siab qhov kev taw qhia
•Thicker chips?Ntawm kev tshem tawm (tsav riam txaj kom deb lossis thim riam me ntsis).
•Thinner chips? Txo tshem tawm (tsav riam txaj los ze zog los yog ncua riam sab nraud ntawm shims).
Ntawm cov tshuab feem ntau txoj kev yooj yim dua yog kho lub txaj riam, vim tias koj tsis tas yuav rub lub nruas riam.
Kauj Ruam 3: Kho lub txaj txaj
• Loosen lub xauv txiv ntseej ntawm lub txaj - riam hloov ntsia liaj qhov rooj.
• Tig lub ntsia liaj qhov rooj: nyob rau hauv kom txav lub dab teg los ze zog rau lub nruas (thinner chips), tawm mus kom deb (cov chips tuab dua).
• Ib tug me me tig mus rau qhov ntev -feem ntau yog¼ tig hloov clearance los ntawm ~ 0.005–0.010″.
•Re-Tighten lub xauv txiv ntseej thiab rov- xyuas nrog lub ntsuas ntsuas ntawm ntau lub ntsiab lus raws li riam (nruas tuaj yeem hneev me ntsis; koj xav tau kev tshem tawm zoo ib yam thoob plaws qhov dav).
Kauj Ruam 4: Lwm Txoj Kev - Cia lub nruas riam
Yog tias koj lub tshuab siv cov hnab ris riam nrog shims:
• Unbolt lub riam bar (koj yuav xav tau ib tug torque ciaj ntswj ntsuas rau riam bolts-feem ntau 150-250 ft-lb).
• Ntxiv los yog tshem tawm stainless shims nyob rau hauv lub riam mount.Ib shim feem ntau yog =~0.015–0.020″ ntawm radial txav.
•Re-torque rau spec.Tsis txhob kwv yees ntawm torque-nyob rau hauv- torqued riam bolts tuaj yeem pov ib rab riam; dhau -torqued tuaj yeem tawg lub nruas hnab tshos.
Kauj Ruam 5: Kho qhov ceev ceev (secondary)
Yog tias koj xav tau cov chips luv dua yam tsis tau kov cov neeg kho tshuab tshem tawm, qeeb cov khoom noj khoom haus.Yog tias koj xav tau cov chips ntev dua, ua kom lawv ceev.Qhov no yuav tsis hloov thickness, tsuas yog ntev -tab sis cov neeg siv khoom feem ntau hais tias "chip loj" txhais tau tias ob qhov ntev, yog li nws tsim nyog hais.
5.Test and Verify
1.Start lub tshuab (raws li ib txwm pib, tsis nyob rau hauv lockout lawm).
2.Ntawm ob peb ceg sim ntawm cov kab uas paub.
3.Catch ib qho piv txwv tes thiab ntsuas:
• Thickness (radial dimension, teem los ntawm clearance)
• Ntev (axial dimension, teem los ntawm pub ceev vs. nruas ceev)
4.Txoj kev lag luam mulch feem ntau xav tau ½ "-1" tuab thiab 1 "-2" ntev, tab sis biomass boilers yuav xav tau 2 "-3" khaub ncaws hnav.
Yog tias cov chips yog ragged los yog tearing es tsis yog sheared huv si, koj cov riam yuav dull -ntse ua ntej caum clearance ntxiv.
6.Cov kev nyuaj siab
•Chasing loj nrog clearance ib leeg thaum riam yog npub.Dull riam khoov ntoo es tsis txhob shearing, ua inconsistent chips tsis hais qhov chaw.
•Qhov tsis sib xws ntawm lub nruas dav.Kuaj tsawg kawg yog peb lub ntsiab lus raws li riam.Qhov tsis sib xws ua rau kev co thiab kev coj tus cwj pwm ntxov ntxov.
•Tsis nco qab rov qab- lub zog tom qab shimming.Ib rab riam xoob yog pov tseg - riam xwm txheej tos tshwm sim.
•Tsis quav ntsej pub cov menyuam siab.Yog tias cov menyuam pub rau sab saum toj tsis txaus siab, cov ntoo tuaj yeem "skate," ua cov chips ntev dua thiab hloov pauv ntau dua. Feem ntau cov cav tov muaj lub caij nplooj ntoos hlav- nro lossis hydraulic-siab adjuster rau qhov no.
7.Cov lus qhia txog kev tu kom muaj qhov sib npaug
• Rotate/spare riam tsis tu ncua kom koj ib txwm muaj tsawg kawg yog ib tug ntse teeb nyob rau hauv lub nruas.
•Kuaj lub txaj- riam hnav daim hlau- thaum lawv raug khawb, kev hloov pauv tau zoo txawm tias qhov chaw ntsia hlau tsis txav.
• Khaws lub nruas bearings kom zoo; lub nruas wobbling hloov clearance dynamically.
•Tau koj qhov chaw tshem tawm ib txoj haujlwm.Yog tias koj hloov los ntawm mulch chips (nyias) mus rau biomass (tick) feem ntau, muaj "daim ntawv qhia" txuag lub sijhawm teeb tsa.
Kho cov nti loj ntawm lub nruas chipper los rau kev tshem tawm ntawm lub nruas riam thiab txaj riam (thawj) thiab pub cov menyuam ceev (thib ob). Nrog lub tshuab kaw, ntsuas koj qhov pib tshem tawm, tweak lub txaj - riam bolts lossis riam shims hauv me me increments, re- torque txhua yam kom ntse, thiab koj qhov kev sim siab. tuav chip loj tsis tu ncua ua haujlwm tom qab ua haujlwm.
📌Ib txwm sab laj nrog koj tus qauv tshwj xeeb phau ntawv qhia kev pabcuam ua ntej kev hloov kho -bolt torque qhov tseem ceeb, kev tshem tawm ntau, thiab kev hloov kho cov ntsiab lus sib txawv los ntawm cov chaw tsim khoom.
