Luv teb:Cov ntsia hlau conveyor (tseem hu ua auger conveyor) yog lub helical hniav tig - lub "flighting" - nyob rau hauv ib lub trough los yog raj uas txav granular, hmoov, los yog semi- khoom ntawm cov txheej txheem cov ntsiab lus. Xaiv ib qho los ntawm kev sib piv cov hom conveyor (shafted vs. shaftless, kab rov tav vs. inclined) rau koj cov khoom tus yam ntxwv (abrasiveness, noo noo, khoom noj khoom haus kev ruaj ntseg yuav tsum), ces loj nws raws li qhov yuav tsum tau muaj peev xwm, ntev, thiab incline. Rau feem ntau ntawm cov haujlwm tuav, ib qho kev qhia kom raug ntsia hlau conveyor yog tus nqi ntau tshaj - zoo thiab qis tshaj - kev kho hloov kho muaj.
Dab tsi yog cov ntsia hlau conveyor thiab nws ua haujlwm li cas?
Lub ntsia hlau conveyor txav cov khoom los ntawm kev tig lub helical ntsia hlau hniav hauv ib qho chaw ruaj khov lossis lub raj. Raws li cov ncej tig, cov khoom raug thawb mus rau pem hauv ntej ntawm kev ya davhlau - tib lub hauv paus ntsiab lus raws li Archimedes 'ntsuab ntsia hlau, uas tau siv txij li thaum ub los mus tso dej rau hauv dej. Niaj hnub nimno ntsia hlau conveyors txav cov khoom pov tseg, ntoo chips, aggregates, cereal nplej, tsiaj pub, boiler tshauv, nqaij, pob txha noj mov, thiab cov khoom pov tseg hauv nroog, ntawm ntau lwm cov khib nyiab. Lub volumetric hloov pauv tus nqi yog proportional rau lub ncej rotation ceev, uas yog vim li cas ntsia hlau conveyors kuj lug siv raws li variable - tus nqi feeders uas ntsuas ib tug ntsuas kom muaj nuj nqis ntawm cov khoom rau hauv ib tug txheej txheem.
Ob lub ntsiab configurations dominate lub khw:
Shafted ntsia hlau conveyors- ib tug kauv hniav coiled nyob ib ncig ntawm lub hauv paus ncej, tsav ntawm ib kawg thiab txhawb los ntawm hanger bearings raws qhov ntev. Lawv yog cov neeg ua haujlwm ntawm kev tuav ntau: tus nqi- ua haujlwm tau zoo, kev saib xyuas tsawg, thiab muaj pov thawj hauv ntau txhiab daim ntawv thov kev lag luam.
Shaftless (centerless) ntsia hlau conveyors- ib tug kauv tsis muaj lub hauv paus ncej, tsav ntawm ib kawg thiab dawb ntawm lwm yam. Lawv tuav cov khoom nplaum, stringy, los yog entangled cov ntaub ntawv uas yuav qhwv ib ncig ntawm ib tug ncej, thiab lawv ua siab ntev sau ntau dua.
Dab tsi ntawm cov ntsia hlau conveyors koj yuav tsum xav txog?
| Hom | Zoo tshaj rau | Kev txwv | Hom kev lag luam |
|---|---|---|---|
| Kab rov tav shafted | Qhuav, pub dawb- cov khoom tawg yooj yim (grains, cement, xuab zeb) | Limited incline muaj peev xwm | Kev ua liaj ua teb, sib sau ua ke, cement |
| Inclined / ntsug | Elevating cov khoom thaum qhov chaw nruj | Lub peev xwm poob qis thaum lub kaum sab xis nce | Grain elevators, recycling |
| Shaftless kauv | Cov ntaub ntawv ntub dej, nplaum, fibrous, lossis cov khoom siv hlua (sludge, zaub mov pov tseg, ntoo chips) | Siab dua torque loads, luv spans | Cov dej khib nyiab, khoom noj khoom haus, biomass |
| Ribbon davhlau | Cov khoom nplaum, pasty, lossis cov khoom tawg yooj yim xav tau kev tuav tes | Muaj peev xwm qis dua ib txoj kab uas hla | Khoom noj khoom haus, tshuaj |
| Slexible ntsia hlau | Hmoov thiab granules nyob ib ncig ntawm obstacles, ntau inlets | Lower throughput, hnav ntawm lub raj | Khoom noj khoom haus, tshuaj, yas |
Yuav ua li cas kuv loj lub ntsia hlau conveyor rau kuv daim ntawv thov?
Sizing yog plaub-qhia kev tawm dag zog. Rau cov qauv tsim, siv CEMA (Conveyor Equipment Manufacturers Association) cov qauv tsim qauv - lub koom haum tau tshaj tawm cov qauv ntsia hlau conveyor engineering thiab daim ntawv thov kev taw qhia txij li xyoo 1933 thiab tseem yog qhov siv rau Asmeskas.
Txhais cov khoom.Bulk density, particle size, moisture, abrasiveness, corrosiveness, and flow characteristics (free-flowing vs. cohesive) drive almost every later decision. Khoom noj khoom haus- cov ntaub ntawv qib yuav xav tau cov hlau tsis huv thiab kev tsim kho huv si; Cov khoom siv abrasive xav tau kev ya dav hlau thiab hnyav dua troughs.
Teeb lub peev xwm thiab ceev.Qhov yuav tsum tau muaj peev xwm (piv txwv li tons ib teev) txiav txim siab txoj kab uas hla, lub suab, thiab RPM. Lub peev xwm ntsuas nrog txoj kab uas hla thiab kev sib hloov ceev, thiab cov trough filling qib feem ntau khaws cia zoo hauv qab 100% kom tsis txhob muaj kev kub ntxhov.
Xyuas qhov ntev thiab incline.Ib tug ntsia hlau conveyor yog feem ntau npaum kab rov tav. Raws li lub kaum sab xis ntawm inclination nce, lub peev xwm txo qis sai sai - ntawm cov kaum sab xis ntsug ntsug lossis lub thoob of elevator feem ntau yog qhov kev xaiv zoo dua.
Txheeb xyuas cov tsav thiab cov khoom thauj khoom.Lub cev muaj zog sizing, txuas bolts, hanger bearings, thiab kawg bearings yuav tsum tau teev rau qhov tseeb torque thiab cov khoom hnyav. Cov khoom tsis zoo yog qhov ua rau ua tsis tiav ntxov. Feem ntau cov tuam ntxhab - suav nrogE-TECH- yuav khiav cov kev ntsuas no rau koj raws li ib feem ntawm cov lus hais, yog li qhov tseeb ntawm koj cov ntaub ntawv cov ntaub ntawv tseem ceeb dua li koj lej.
Yuav ua li cas piv cov ntsia hlau conveyor nrog siv conveyors thiab thoob elevator?
Rau cov ncauj lus sib tw, lub rooj sib piv ncaj qha tshem tawm kev kwv yees:
| Cov txheej txheem | Ntsia hlau conveyor | Siv conveyor | Lub thoob of elevator |
|---|---|---|---|
| Zoo tshaj rau | Luv-rau- qhov nruab nrab qhov deb, ntsuas ntsuas, hloov pauv hauv ib puag ncig | Ntev mus ntev, siab tonnage, maj mam tuav | Vertical lifting ntawm dawb - ntws bulk solids |
| Enclosure / plua plav tswj | Npog tag nrho - zoo heev | Qhib lossis tiab - nruab nrab | Npog - zoo |
| Nqi | Tsawg mus rau nruab nrab CAPEX thiab OPEX | Nruab nrab CAPEX, qis zog ib tuj | Nruab nrab CAPEX |
| Kev tu | Tsawg heev (cov kabmob, cov ntsaws ruaj ruaj) | Ntau zaus (siv txoj siv taug qab, idlers) | Nruab nrab ( thoob, saw) |
| Cov khoom tawg yooj yim | Yuav degrade cov khoom friable | Maj mam | tuaj yeem degrade ntawm cov ntsiab lus thauj khoom |
| Lub peev xwm ntawm lub kaum sab xis | Kab rov tav mus rau ~ 15-20℃zoo; ntsug nrog cov qauv tsim tshwj xeeb | Txwv tsis pub | Vertical standard |
Dab tsi yog hom ntsia hlau conveyor tsis ua haujlwm ntau tshaj - thiab kuv yuav tiv thaiv lawv li cas?
Kev saib xyuas tsis ua haujlwm hauv cov ntsia hlau conveyors pawg nyob ib ncig ntawm ob peb qhov zoo-cov ntsiab lus sau tseg:
Hanger bearing hnav.Hanger bearings txhawb nqa ncej ntawm ntu; hnav ua rau misalignment, vibration, thiab qhov kawg ncej puas. Tshawb xyuas lawv ntawm lub sijhawm thiab hloov ua ntej lawv txeeb - kev saib xyuas tsis tu ncua yog ib txoj cai pov hwm pheej yig tshaj.
Coupling ncej thiab ntsia liaj qhov rooj -nyob rau hauv -shear tsis ua hauj lwm.Coupling bolts kis torque ntawm cov ntsia hlau; Yog hais tias undersized los yog tsis tsim nyog torqued, lawv tsis nyob rau hauv shear. Faib cov kabmob kev ntxhov siab dhau ntawm thaj chaw loj txaus thiab txheeb xyuas qhov kev xaiv bolt tiv thaiv lub zog tsav.
Seal leakage ntawm qhov kawg tsav.Plua plav thiab nplua khiav tawm los ntawm hnav cov ntsaws ruaj ruaj, paug ib puag ncig thiab ua kom cov kabmob puas.
Davhlau thiab trough hnav.Abrasive cov ntaub ntawv (xuab zeb, cement, tshauv) eroded davhlau npoo thiab trough bottoms. Qhia meej txog kev ya dav hlau hnyav, cov ntaub pua tsev tuab dua, lossis kev puas tsuaj - cov ntaub ntawv tiv taus pem hauv ntej - cov khoom siv rov qab raug nqi ntau dua li qhov qub hloov tshiab.
