Taw qhia rau Longwall Shearer Tus Nqi Ua Haujlwm
Nyob rau hauv niaj hnub underground thee mining, lub longwall shearer pab raws li lub meej mem tes ntawm ntau lawm. Muaj peev xwm rho tawm ntau txhiab tons ntawm cov thee hauv ib teev, txhua qhov tsis tau teem sijhawm nres ntawm lub tshuab loj tam sim ntawd nres lub ntsej muag conveyor, lub ru tsev txhawb nqa, thiab lub tshuab thauj khoom loj. Cov ntaub ntawv hauv kev lag luam qhia tias lub sijhawm poob qis ntawm qhov siab - lub ntsej muag longwall tuaj yeem ua rau cov neeg ua haujlwm mining nyob qhov twg los ntawm $ 10,000 mus rau ntau dua $ 50,000 toj ib teev hauv cov nyiaj tau los poob. Yog li ntawd, cov neeg yuav khoom, cov neeg saib xyuas kev tu vaj tse, thiab cov kws tshaj lij kev muag khoom tseem ceeb tshaj ib qho kev ntsuas siab tshaj tag nrho lwm tus: kev ntseeg tau ntawm kev ua haujlwm.
Thaum ntsuam xyuas cov khoom hloov pauv rau longwall shearers, cov neeg yuav khoom feem ntau ntsib ib qho kev xaiv nyuaj ntawm cov khoom kim heev Original Equipment Manufacturer (OEM) nrog cov sij hawm txhuas ntev thiab qis dua - nqi tom qab kev hloov pauv ntawm qhov tsis zoo. Txawm li cas los xij, ua tiav lub sijhawm ua haujlwm siab tshaj plaws tsis tas yuav them tus nqi OEM nqi cim npe. Los ntawm kev muab cov khoom ua tau zoo- hloov cov khoom siv hluav taws xob los ntawm cov kws tshaj lij engineering uas muaj pov thawj, kev ua haujlwm tsuas tuaj yeem ua kom lub sijhawm ua haujlwm tsis tu ncua, kev ua haujlwm ruaj khov, thiab cov sijhawm saib xyuas tau zoo.
Qhov tseeb hauv paus ua rau Shearer Mechanical Failure
Longwall shearers ua haujlwm hauv qee qhov chaw nruj tshaj plaws hauv ntiaj teb. Lawv niaj hnub raug rau cov plua plav abrasive heev, cov dej noo siab, kev ntxhov siab ntawm cov qauv, thiab ntau yam - kev taw qhia kev poob siab. Shearer cov neeg yuav khoom nquag tshawb nrhiav cov kev daws teeb meem los tiv thaiv kev ua tsis tiav, suav nrog:
Haulage Unit thiab Sprocket Wear:Kev koom tes tsis tu ncua nrog cov khib nyiab ntawm lub ntsej muag armored conveyor (AFC) ua rau muaj kev sib txhuam loj heev. Inferior metallurgy ua rau cov hniav tawg, pitch distortion, thiab tsis ua hauj lwm ntxov ntxov.
Txiav Lub Taub Hau thiab Vane Degradation:Txiav nruas nqus cov kev cuam tshuam loj heev thaum tawm tsam kev sib koom ua ke, pyrites, lossis pob zeb intrusions. Cov khoom tsim tsis zoo xaiv lub tes tsho los yog hnav cov paib vane txo qhov kev ua tau zoo thiab ua kom muaj kev vibration thoob plaws hauv lub tshuab.
Gearbox thiab Transmission Breakdown:Siab torsional kev nyuaj siab ntawm lub zog, ncej, thiab planetary txo units tuaj yeem ua rau iav hniav pitting, bearing qaug dab peg, thiab thermal tawg ntawm lubricants.
Hydraulic thiab Structural Fatigue:Kev vibration tsis tu ncua ua rau cov txheej txheem ntawm caj npab castings, pob khawm pins, thiab hydraulic lub tog raj kheej mountings, tsim micro- pob txha uas ua rau lub cev tsis ua hauj lwm tam sim ntawd.
Hais txog qhov mob cov ntsiab lus no yuav tsum tau hloov cov khoom siv nrog cov khoom siv hlau ua kom zoo, tswj kev kho cua sov, thiab ultra- qhov ntev ntawm qhov ntev.
Cov Txheej Txheem Tseem Ceeb rau Longwall Cov Khoom Muag
Pab pawg neeg yuav khoom ntsuas cov khoom hloov shearer tsom rau cov peev txheej tshwj xeeb thiab kev lag luam:
1. Cov Khoom Siv Kev Ncaj Ncees thiab Metallurgical Standards:Cov khoom yuav tsum tau siv high- tensile alloy steels (xws li 18CrNiMo7-6, 42CrMo, los yog tshwj xeeb forging alloys) tsim los tiv taus siab yam tsis muaj kev puas tsuaj.
2. Dimensional Exactness thiab Interchangeability:Cheebtsam yuav tsum ua kom haum OEM specifications seamlessly yam tsis tas yuav tsum tau nyob rau ntawm - hloov chaw los yog haum haum thaum lub sij hawm ceev underground txij nkawm hloov.
3. Kev kho cua sov saum npoo av:Sib sib zog nqus carburizing, nitriding, thiab induction hardening yog qhov tseem ceeb los muab cov tawv tawv tawv (tiv thaiv abrasive hnav) thaum tuav cov tawv tawv, ductile inner core (absorbing hnyav shock loads).
4. Supply Chain Ceev thiab Lead Time Txo:Tus qauv OEM coj lub sijhawm tuaj yeem txuas mus rau ob peb lub hlis. Cov neeg siv khoom lag luam txhim khu kev qha yuav tsum muaj cov khoom lag luam lossis cov khoom lag luam nrawm kom xa cov khoom tseem ceeb sai.
Koom tes nrog SHAANXI HELI MECHANICAL ENGINEERING CO., LTD.
SHAANXI HELI MECHANICAL ENGINEERING CO., LTD. yog lub ntiaj teb no -chaw tsim khoom thiab thoob ntiaj teb exporter tshwj xeeb hauv hnyav- lub luag haujlwm longwall shearer Cheebtsam. Nkag siab txog qhov tsis yog -xav tau kev thov kom muaj kev ntseeg siab hauv kev lag luam hauv av, HELI sib txuas cov kev tshawb fawb metallurgical siab heev nrog - precision CNC machining los tsim cov khoom uas ua tau raws li lossis tshaj OEM cov qauv.
HELI cov khoom lag luam nthuav dav suav nrog siab - lub zog thauj khoom sprockets, txiav lub nruas vane hloov ntu, hnyav- lub luag haujlwm iav teeb, planetary iav vaj tse, tsav shafts, xaiv cov blocks, thiab cov qauv pob khawm pins.
Tseem ceeb heev, SHAANXI HELI pab pawg neeg ua haujlwm tsim khoom tsim cov khoom siv hloov pauv rau seamless compatibility nrog lub ntiaj teb no tus thawj longwall shearer hom, xws li Joy (Komatsu Mining) thiab Eickhoff, nrog rau sab saum toj Suav shearer manufacturers xws li Tiandi (SJTU), SANY, thiab Xi'an Coal Mining Machinery.
Los ntawm kev xaiv SHAANXI HELI MECHANICAL ENGINEERING CO., LTD., cov neeg ua haujlwm longwall thoob ntiaj teb tau txais ib tus neeg koom tes uas ntseeg siab tau cog lus los txo tus nqi - ib - tuj, tshem tawm lub sijhawm poob qis, thiab muab kev cia siab, siab - cov khoom seem ncaj qha rau ntawm qhov chaw kuv.
