Cov cav tov thiab cov khoom siv yuav tsum tau ua haujlwm nyob rau hauv ib puag ncig hnyav, tsis tas yuav tsum muaj kev twv ua ntej, thiab tuaj yeem tiv taus cov kev hloov pauv ntau dhau, kub, av noo, thiab muaj kuab paug. Kev xaiv cov roj nplua nyeem zoo yog qhov tseem ceeb rau kev txo qis hnav, txo qis lub sijhawm poob qis, thiab txuas ntxiv lub neej ntawm cov khoom muaj nqis. Nyob rau hauv cov xwm txheej mining ntau dhau, tsis yog txhua lub lubricants zoo ib yam. Qhov no yog vim li cas lubricants tiag tiag sawv tawm thiab hom twg yog qhov tsim nyog tshaj plaws rau cov ntawv thov mining nyuaj tshaj plaws.
Kev sib tw hauv Mining Ib puag ncig
Cov khoom siv mining xws li drilling rigs, excavators, trailers, thiab crushers ua haujlwm nyob rau hauv qee qhov kev xav tau tshaj plaws. Qhov no suav nrog:
Qib siab plua plav thiab abrasive hais
Tiv thaiv kom ntub dej thiab Frost
Tshaj siab thiab cuam tshuam load
Dav kub ntau, los ntawm khov mus rau huab cua kub
Nruam hnyav thiab ua haujlwm ntev -
Cov roj nplua nyeem feem ntau ua tsis tiav nyob rau hauv cov xwm txheej zoo li no, ua rau muaj kev sib xyaw ua kom nrawm dua, txhim kho ntau zaus, thiab tsis npaj them nqi poob qis.
Cov yam ntxwv tseem ceeb ntawm qhov zoo tshaj plaws mining lubricating roj
Lub zoo tagnrho lubricating roj haum rau huab mining tej yam kev mob yuav tsum muaj cov nram qab no yam ntxwv:
1. Tshwj xeeb thermal stability
Ua kom kub ua haujlwm siab yam tsis muaj kev puas tsuaj, tswj cov viscosity zoo ib yam thiab kev tiv thaiv kev ua haujlwm.
2. Kev hnav zoo heev thiab kev tiv thaiv siab heev (EP)
Muab cov tshuaj tiv thaiv siab tshaj - hnav thiab EP additives los tiv thaiv cov khoom nyob rau hauv hnyav loads thiab tiv thaiv hlau rau hlau.
3. Dej tsis kam thiab lub cev qhuav dej tsis kam
Nws muaj peev xwm los tiv thaiv emulsification thiab sai sai cais tawm ntawm dej, yog li txo qhov kev pheej hmoo ntawm corrosion thiab lubricating roj daim kab xev.
4. Antioxidant kev ua haujlwm
Nws txuas nws lub neej kev pab cuam los ntawm kev hais txog tshuaj lom neeg degradation, txawm tias muaj kuab paug.
5. Zoo heev los tiv thaiv -corrosion zog
Tiv thaiv hlau nto los ntawm yaig thiab corrosion los ntawm ya raws thiab acidic los ntawm - khoom.
6. Kev ua kom huv siab thiab tawg
Nws tswj qhov kev huv huv los ntawm kev ncua thiab tshem tawm cov pa phem, av nkos, thiab sediment.
Kev daws teeb meem: kev xaiv ua ntej
Synthetic lubricants, tshwj xeeb tshaj yog cov tsim nrog siab -cov roj hauv paus kev ua tau zoo thiab kev ntim khoom ntxiv, tau raug pov thawj tias yog cov kev daws teeb meem zoo tshaj plaws rau kev siv mining. Cov roj no muab:
Txhim kho kev ua haujlwm ntawm qhov kub thiab txias
Ntxiv cov kev pab cuam ncua sij hawm, txo downtime thiab tu nqi
Txhim kho roj efficiency thiab kev cia siab rau kev ua haujlwm
Kev tiv thaiv siab tiv thaiv oxidation, thermal cracking, thiab sediment tsim
Kev siv cov khoom siv mining
Qhov tseeb lubricating roj tuaj yeem txhim kho kev ua haujlwm ntawm tag nrho cov khoom siv ntau yam:
Hydraulic system: Ua haujlwm zoo thiab twj tso kua mis thiab kev tiv thaiv valve
Kev xa mus: Nws ua haujlwm siab cuam tshuam loads thiab txo cov poholes thiab hnav
Lub cav: Muab kev ntxuav thiab tiv thaiv- hnav ua haujlwm hauv qhov chaw muaj plua plav
Bearings thiab pob qij txha: txo qhov kev tiv thaiv thiab tiv thaiv kev ua txhaum
Environmental thiab kev ua haujlwm zoo
Ntxiv nrog rau kev tiv thaiv cov cuab yeej, cov mining lubricants zoo tshaj plaws kuj ua tiav cov hom phiaj kev txhim kho kom ruaj khov los ntawm cov hauv qab no:
Tso cai rau kev siv roj mus ntev dua thiab txo cov khoom pov tseg
Txhim kho lub zog efficiency los ntawm kev txo cov kev ntxhov siab
Txhawb nqa cov cuab yeej siv ntev ntev thiab txo qhov cuam tshuam tag nrho ntawm ib puag ncig
Xaiv cov roj lubricating kom raug
Thaum xaiv cov roj nplua nyeem rau cov khoom siv mining ntau dhau, nws yuav tsum xav txog:
OEM specifications thiab cov kev xav tau
Environmental tej yam kev mob (kub, humidity, muaj kuab paug txaus ntshai)
Compatibility ntawm lubricants nrog cov ntaub ntawv uas twb muaj lawm thiab kua
Cov ntawv pov thawj nruj nruj thiab cov ntaub ntawv ua haujlwm tau zoo
Nyob rau hauv hnyav mining tej yam kev mob, lub lubricant uas yog tsis yog tsuas yog ib tug txij nkawm cov khoom, tab sis kuj yog ib feem tseem ceeb rau kev ua tau zoo. Synthetic lubricants muaj qhov zoo tshaj plaws tus nqi thiab kev ua tau zoo, tsim los muab cov thermal stability siab, tiv thaiv kev kub siab, thiab kev ua pa phem. Los ntawm kev nqis peev hauv cov kev daws teeb meem zoo tshaj plaws, kev ua haujlwm tsuas tuaj yeem txhim kho kev ntseeg tau zoo, txo cov nqi, thiab ua kom muaj txiaj ntsig zoo tshaj plaws hauv ntiaj teb qhov chaw hnyav tshaj plaws.
