Yuav Ua Li Cas Pairing, Installation thiab Kho Cov Mining Flat Link Chains?
Raws li ib puag ncig steel txuas saw chaw tsim khoom rau 30 xyoo, peb zoo siab los qhia txoj hauv kev ntawm Pairing, Installation thiab Kho Cov Mining Flat Link Chains.
1. Khoom nta
Mining high-strength flat link saw muaj cov yam ntxwv ntawm lub peev xwm loj, muaj zog hnav tsis kam, zoo cuam tshuam toughness thiab ntev lub neej qaug zog.
2. Lub hom phiaj tseem ceeb thiab Scope ntawm daim ntawv thov
Nws yog dav siv hauv Armored Face Conveyor (AFC) thiab Beam Stage Loader (BSL) hauv cov thee mine.
3. Tus Qauv Txheej Txheem
MT / t929-2004, DIN 22255
4. Pairing thiab Installation
4.1 Flat link chains pairing
Kev sib raug zoo ntawm cov mining tiaj tus txuas chains yog qhov tseem ceeb rau kev ua haujlwm tiav ntawm cov khoom siv conveyor.Thaum cov saw hlau tawm ntawm lub Hoobkas, nws tau ua ke nrog ib-rau-ib txoj hlua txuas los xyuas kom meej tias cov scraper nyob rau hauv ib txoj kab ncaj nraim thiab kev ruaj ntseg ntawm cov scraper nyob rau hauv nruab nrab groove.Muab cov hlua txuas txuas ncaj nraim rau hauv ib lub thawv ntim khoom thiab muab ib daim ntawv lo rau txhua qhov sib txuas.Paired chains yuav tsum tsis txhob siv cais.Pairing kam rau ua yog hais txog qhov ntev tshaj plaws uas tau tso cai ntawm txhua txoj hlua sib txuas.
4.2 Flat txuas chains installation
Cov hlua txuas txuas txuas txuas tau raug sib sau ua ke ntawm lub scraper kom ua tau zoo ntawm cov saw hlau.Qhov no yuav ua kom ntseeg tau tias qhov kam rau ntawm ob sab ntawm cov saw hlau raug txo kom tsawg thiab cov saw nro yog tswj tau zoo thaum lub tshuab scraper pib pib.Xyuas kom lub ntsej muag ncaj ncaj thiab txo qhov sib txawv ntawm kev ua phem.
Cov saw yog ntsia rau hauv khub, thiab cov hlua txuas ntev thiab cov hlua luv luv tau sib sau ua ke hauv lem.Tshiab sprockets thiab baffles feem ntau yog sib sau ua ke thaum txhim kho cov hlua txuas tshiab.
Xyuas kom tseeb tias lub tiaj txuas chains tsis khiav thaum nws yog thawj zaug ntsia tsis muaj lubrication lav.Yog tias nws khiav tsis muaj lubrication, cov saw txuas yuav hnav sai.
Xyuas kom meej tias cov txheej txheem tensioning yog tsim nyog rau scraper conveyors thiab hloov tshuab.Tshawb xyuas qhov nro ua ntej txhua hnub txhawm rau tsim kom muaj tus nqi nro haum rau txhua txoj saw.Vim tias cov saw hlau nws tus kheej thiab nws txoj kev koom tes nrog cov conveyor yuav tsum tau khiav hauv qhov chaw, thawj ob peb lub lis piam ntawm kev ua haujlwm ntawm cov cuab yeej yog qhov tseem ceeb heev.
5. Flat Link Chains Maintenance
5.1 Kev ua haujlwm
Scraper conveyor chains, scrapers thiab saw txuas txuas (connectors) yog cov khoom siv, uas yooj yim hnav thiab puas thaum rov siv dua.Yog li ntawd, kev txij nkawm ntawm cov hlua txuas ncaj nraim yog qhov tseem ceeb heev los ua kom lub neej ua haujlwm ntev ntawm cov saw hlau thiab xyuas kom muaj kev pheej hmoo tsawg kawg ntawm cov saw tsis ua haujlwm.
Khaws qhov ncaj ntawm qhov chaw ua haujlwm kom raug raws li qhov ua tau.
Yog tias lub ntsej muag ua haujlwm tsis ncaj, nws tuaj yeem ua rau sib txawv ntawm kev hnav thiab elongation ntawm cov saw hlau.
Lub kaum sab xis ntawm lub nraub qaum ntawm lub shearer yog minimized.Yog tias nws nruj heev, nws yuav ua rau kom lub zog xav tau thiab cov saw hnav.
Siv cov txheej txheem kev tswj xyuas cov saw hlau kom ntseeg tau tias txhua qhov kev ua haujlwm tau txais kev cob qhia thiab cov kev coj ua zoo tshaj plaws tau ua tiav raws li kev taw qhia ntawm cov chaw tsim khoom siv conveyor, ua raws li cov txheej txheem, tswj thiab khaws cov ntaub ntawv.
5.2 Cov lus pom zoo txog kev saib xyuas
Hauv qee qhov thee mines, kev saib xyuas kev ua haujlwm ntawm cov hlua txuas ncaj nraim yog qhov tseem ceeb ntawm tus neeg teb xov tooj qhov kev lees paub ntawm cov saw hlau pretension, uas tuaj yeem tswj tau cov saw hlau zoo.Vim tias qhov xwm txheej ntawm kev txo qis tus nqi yog qhov tseem ceeb los tiv thaiv qhov tsis ua haujlwm thaum ntxov ntawm cov saw hlau.Cov hauv qab no yog cov ntsiab lus ntawm qee cov ntsiab lus tseem ceeb, thiab cov lus qhia muab los ntawm cov chaw tsim khoom siv conveyor yuav tsum tau ua.
- Txheeb xyuas qhov nro ua ntej txhua hnub, tshwj xeeb tshaj yog ob lossis peb lub lis piam ua ntej kev teeb tsa tshiab thiab kev ua haujlwm ntawm cov saw hlau.
- Txheeb xyuas cov chute conveyor ua ntej pib kom paub tseeb tias tsis muaj qhov tsis xws luag lossis teeb meem.
- Hloov cov scraper puas thiab saw txuas kom sai li sai tau.
- Tshem tawm cov saw hlau puas lossis tawg thiab xyuas qhov elongation ntawm cov saw hlau uas nyob ib sab.Yog tias nws tsis ua raws li qhov yuav tsum tau ua, nws yuav tsum raug tshem tawm raws sijhawm.Yog tias cov saw hlau tau hnav, cov saw hlau ntawm ob sab yuav tsum tau hloov tib lub sijhawm txhawm rau txhawm rau tswj kev sib txuas ntawm cov saw hlau.
- Tshawb xyuas cov chains puas, baffles thiab sprockets thiab hloov lawv yog tias tsim nyog.
- Tshawb xyuas lub scraper kom xoob, ploj thiab puas cov khoom txuas.
- Tshawb xyuas cov saw rau hnav thiab elongation.Vim hais tias hnav los yog elongation hauv qhov txuas (qhia ntau dhau) lossis ob qho tib si yuav ua rau cov saw ntev ntev.
Thaum lub tiaj txuas saw yog overloaded thiab stretched, nws yog pom tseeb hais tias muaj deformation, uas ua rau ib tug natural nce nyob rau hauv tag nrho ntev ntawm cov saw txuas.Qhov no yuav cuam tshuam rau tus naj npawb ntawm cov txuas uas nyob ib sab, uas ua rau cov saw hlau tsis sib xws.Nyob rau hauv rooj plaub no, qhov cuam tshuam yuav tsum tau hloov, thiab yog hais tias lub saw yog hnav, cov chains ntawm ob sab yuav tsum tau hloov nyob rau tib lub sij hawm los tuav lub khub ntawm chains.
- Feem ntau, cov saw yog elastically stretched thiab yuav rov qab mus rau lub suab qub tom qab unloading.Kev hnav sab hauv ntawm qhov txuas yuav ua rau lub suab ntawm cov saw hlau, qhov ntev ntawm qhov txuas yuav tsis hloov, tab sis tag nrho ntev ntawm cov saw yuav nce.
- nws raug tso cai kom nce cov saw hlau los ntawm 2.5%.
6. Flat Link Chains thauj thiab khaws cia
a.Ua tib zoo saib xyuas kev tiv thaiv xeb thaum thauj thiab khaws cia;
b.Lub sijhawm khaws cia yuav tsum tsis pub tshaj 6 lub hlis txhawm rau tiv thaiv corrosion thiab lwm yam los ntawm kev txo cov kev pab cuam lub neej.
