Cov kab xa tawm raws ntug dej hiav txwv hauv nruab nrab ntawm Nyab Laj yuav tsum tau nrog tshuaj tsuag ntsev thiab los nag txhua xyoo puag ncig. Thaum cov neeg siv khoom los ntawm Da Nang tuaj rau peb lub rooj muag khoom ntawm lub rooj nthuav qhia, qhov uas lawv tau tham txog feem ntau tsis yog cov txheej txheem lossis cov nqi, tab sis qhov tseeb tias lawv poob - tawm fuses tsis tuaj yeem nyob ntev ob xyoos los ntawm hiav txwv. Qhov teeb meem no yeej muaj tshwm sim nyob rau hauv cov ntug dej hiav txwv ntawm cov teb chaws Asia, tab sis thaum cov neeg siv khoom nqa cov duab tiag tiag thiab cov ntaub ntawv khaws cia thiab muab txhua yam tso rau ntawm lub rooj, peb paub tias peb yuav tsum ua tiag tiag.
Cov neeg siv khoom tam sim no poob- tawm fuses tau teeb tsa ntawm kab tsawg dua peb mais ntawm ntug hiav txwv. Lub hiav txwv cua nqa ntsev txhua xyoo, thiab thaum lub caij los nag los txog, cov khoom siv zaum hauv qhov ntub dej ib hnub dhau ib hnub. Ordinary galvanized qhov chaw pib tsim cov xeb dawb hauv ob xyoos. Ua ntej, cov khoom siv dawb oxidation tshwm nyob rau saum npoo ntawm bolts thiab brackets; ces cov xeb ua nws txoj kev tob. Thaum cov txheej txheem galvanized tau noj, lub hauv paus hlau yog ncaj qha raug, thiab corrosion speeds ntau dua. Lub fuse tube pivot yog qhov feem ntau txav mus rau hauv tag nrho lub rooj sib txoos - txhua qhov kev kaw thiab qhib kev ua haujlwm tig ib ncig ntawm nws. Thaum ntsev rust nkag mus rau hauv lub clearance ntawm bushing, kev sib txhuam tsim. Thaum lub fuse yuav tsum poob, lub mechanism sticks. Lub fuse caij melts tab sis lub raj nyob twj ywm dai rau ntawd, qhov txhaum tam sim no tsis raug rho tawm, thiab lub transformer qab nws them tus nqi. Tom qab ntawd, nyob rau hnub cua daj cua dub, cua{11}}vim viav vias ua rau muaj kev vibration ntawm tus ncej. Lub rusted pivot, twb xoob nyob rau hauv ib qho kev taw qhia, cia lub fuse raj poob ntawm nws tus kheej, thiab ib tug zoo kawg nkaus kab dheev poob ib theem. Cov neeg siv khoom tau hais rau peb tias kev ua haujlwm nrog cov hom no "yuav tsis poob thaum nws yuav tsum, poob thaum nws tsis tsim nyog" qhov xwm txheej muaj lawv cov neeg saib xyuas khiav tawm ntawm ko taw.
Kev nqus dej noo hauv lub raj fuse yog lwm qhov teeb meem zais. Cov kab ntawv phenolic ib txwm muaj cov rwb thaiv tsev txaus thiab lub zog txhua yam hauv qhov chaw qhuav, tab sis nyob rau hauv qhov siab - cov av noo nyob ntawm ntug dej hiav txwv, cov ntawv raj ua zoo li daim txhuam cev. Thaum nws absorbs noo noo, lub rwb thaiv tsev tiv thaiv poob thiab me me delaminations tshwm nyob rau hauv lub raj phab ntsa. Qhov siab - kub, siab - cov pa roj uas tsim tawm thaum lub sij hawm arc quenching tuaj yeem tawg tawm ntawm cov ntsiab lus tsis muaj zog, thiab nyob rau hauv cov xwm txheej hnyav lub raj tsuas yog tawg. Nyob rau saum npoo nws zoo li qhov teeb meem tshwm sim los ntawm xob laim lossis overload, tab sis lub hauv paus ua rau yog ib txhij poob ntawm rwb thaiv tsev thiab arc - quenching muaj peev xwm tom qab ntawv lub raj tau damp.
Ntawm qhov kev nthuav qhia, peb muab cov neeg siv khoom coj los daws teeb meem. Lawv pom zoo qhov kev taw qhia yog lawm tab sis hais tias cov ntsiab lus yuav tsum tau ua kom tiav tom qab ntawd. Thawj qhov uas peb tau ua thaum peb tau rov qab los yog rub peb cov neeg tsim khoom lag luam mus rau hauv chav sib tham thiab mus dhau ntawm cov neeg siv khoom ua haujlwm ib puag ncig thiab cov duab tsis raug los ntawm taw tes kom ua tiav cov phiaj xwm.
Lub hauv paus ua rau cov teeb meem xeb yog qhov tsis sib xws ntawm cov ntaub ntawv thiab cov qib kho saum npoo ntawm ib sab, thiab ib puag ncig ntawm lwm qhov. Ordinary galvanized qhov chaw cia siab rau cov zinc txheej txheej los tiv thaiv lub hauv paus hlau nyob rau hauv nruab nrab ntsev tsuag tej yam kev mob. Thaum cov ntsev tsuag concentration siab nyob rau ntawm ntug hiav txwv dej, cov zinc tau noj ntawm tus nqi sai dua, thiab cov xeb dawb nyob rau hauv ob xyoos txhais tau tias cov txheej galvanized tau ploj mus. Yog li thawj kauj ruam hauv peb txoj kev daws teeb meem yog txhawm rau txhim kho cov khoom siv rau cov hlau. Cov tuav tuav sab saud, tus tuav tuav qis, pivot, lub caij nplooj ntoos hlav, thiab cov bolts fastening yog txhua yam hloov mus rau stainless hlau, tshwj xeeb yog qib 316L, uas muaj molybdenum. Molybdenum ho txhim kho cov hlau tsis muaj steel tsis kam rau pitting corrosion hauv chloride ib puag ncig. The pivot and spring get an additional passivation treatment to form a dense passive film on the surface, adding an extra layer of protection. Rau cov txheej txheem loj xws li cov hlua khi, qhov hloov cov khoom siv tsis tshua muaj txiaj ntsig, peb khaws kub -dip galvanizing tab sis nce qhov tsawg kawg nkaus txheej thickness los ntawm ib qib piv nrog tus qauv qub. Kev ntsuas ntsev ntsev yog txuas ntxiv los ntawm ib txwm 400-500 teev ncaj nraim mus rau 1,000 teev, kom ntseeg tau tias tsawg kawg tsib xyoos ntawm kev tiv thaiv lub neej nyob rau hauv ib puag ncig ntug hiav txwv.
Cov dej noo- pov thawj lub raj fuse yog qhov tseem ceeb tshaj plaws ntawm tag nrho cov tshuaj. Phenolic ntawv raj yog hygroscopic los ntawm xwm; pleev xim rau sab nrauv los yog qhwv lawv tsis tuaj yeem daws qhov teeb meem tseem ceeb, vim tias noo noo ib txwm pom ib txoj hauv kev. Cov txheej sab hauv yog ib qho arc-quenching cov khoom uas siv qhov kub thiab txias ntawm arc los tsim cov pa roj thiab tua nws. Cov txheej txheej sab nrauv yog iav -fiber reinforced yas (FRP) sheath. Ob txheej txheej yog tsim ua ke, tsis muaj kev sib koom ua ke. FRP nws tus kheej tsis nqus dej, thiab nws lub zog yog qhov kev txiav txim siab ntau dua li cov ntawv raj, yog li cov pob thaum thauj thiab teeb tsa tsis tshua muaj kev puas tsuaj rau lub raj raj. Nrog rau txoj hauv kev no, lub rwb thaiv tsev tsis kam ntawm lub raj fuse yuav tsis poob qis thaum lub sijhawm ntub dej, thiab qhov sib xws ntawm arc{10}}quenching kev ua tau zoo yog lav zoo dua.
Raws li kev khiav hauj lwm kev ntseeg siab ntawm kev poob mechanism, dhau li ntawm cov ntaub ntawv thiab kev tiv thaiv xeb, cov qauv nws tus kheej yuav tsum tau tawm ntawm qee qhov kev zam. Peb tau so me ntsis qhov kev tshem tawm ntawm qhov pivot haum thiab ntxiv tus kheej -lubricating txheej rau ntawm phab ntsa sab hauv ntawm bushing. Txoj kev no, txawm tias cov cuab yeej siv tsis tau ua haujlwm rau lub sijhawm ntev thiab cov ntsev me ntsis ua rau ntawm qhov chaw, nws yuav tsis txeeb ntawm thawj qhov haujlwm. Peb kuj tau nce qhov pib torque nyob rau hauv lub caij nplooj ntoos hlav xaiv los xyuas kom meej lub mechanism muaj peev xwm kov yeej ib tug tej yam nqi ntawm zoo li qub kev sib txhuam tom qab lub fuse caij melts, guaranteeing txhim khu kev qha tripping. Cov kev hloov kho no tsis tau ua los ntawm kev xav. Lawv yog raws li cov neeg siv khoom ntawm - cov ntaub ntawv cua ceev thiab ncej kev vibration amplitude, thiab tau rov sim thiab txheeb xyuas hauv peb lub hoobkas.
Tsawg tshaj li ib hnub tom qab peb xa daim ntawv thov, tus neeg siv khoom teb. Lawv tau hais tias lawv cov neeg saib xyuas mob taub hau loj tshaj plaws yog qhov ua rau muaj kev tsis haum xeeb tom qab lub caij cua daj cua dub - ib kab tuaj yeem xav tau kev kho mob xwm txheej ceev ntawm ob peb lub ntsiab lus, thiab ntau qhov teeb meem no tshwm sim los ntawm lub raj xeb thiab ya raws. Peb cov kev daws teeb meem daws cov teeb meem xeb thiab noo noo sib cais, cov txheej txheem yog qhov tsim nyog, thiab cov kev ntsuas tau ua tiav, yog li lawv cov kev tshuaj xyuas sab hauv dhau los ntawm ib qho mus.
Qhov kev paub tag nrho no tau qhia rau peb thiab. Cov kev cai rau cov khoom siv ntawm cov kab ntug dej hiav txwv nyob rau sab hnub tuaj Asia yog txawv kiag li ntawm cov cheeb tsam hauv av, thiab koj tsis tuaj yeem siv cov khoom siv dav dav rau txoj haujlwm. Thaum cov neeg siv khoom hais tias lawv xav tau "qib siab dua ntawm kev tiv thaiv corrosion," nws tsis tuaj yeem ua tiav los ntawm kev ntxiv cov txheej tuab galvanized. Kev xaiv cov khoom siv, kev kho deg, rwb thaiv tsev, thiab cov txheej txheem tsim txhua yam yuav tsum tau hloov kho ua ke kom ua tau ib yam khoom uas haum rau lub hiav txwv ib puag ncig. Lub sijhawm tsim khoom rau Da Nang qhov kev txiav txim yog twb nyob rau hauv qhov chaw, thiab peb yuav txuas ntxiv taug qab yuav ua li cas cov neeg ntes ua tom qab kev teeb tsa. Peb npaj yuav coj qhov kev daws teeb meem ntug dej hiav txwv no thiab maj mam txhim kho nws los ntawm ib tus neeg siv khoom xav tau rau hauv cov khoom lag luam paub tab.
