Lifecycle Maintenance and cost Control of Fastening Systems
Yuav ua li cas lub installation zoo ntawm fastening system cuam tshuam cov nqi kho tom ntej?
Lub installation zoo ntawm fastening system ncaj qha txiav txim siab theem ntawm cov nqi kho. Yog hais tias lub bolt torque ua tsis tau raws li tus qauv, nws yuav ua rau loosening ntawm rail clips thiab siab daim hlau, yuav tsum tau nce kev soj ntsuam zaus thiab re-tightening ua hauj lwm, uas ua rau luv luv- cov nqi tu. Qhov tsis zoo ntawm cov tsheb ciav hlau thiab cov tsheb ciav hlau thaum lub sijhawm teeb tsa yuav ua rau hnyav hnyav hauv zos, ua rau lub voj voog hloov ntawm cov tsheb ciav hlau los ntawm 5 xyoo mus rau 2-3 xyoos, ua rau muaj qhov nce ntxiv hauv qhov ntev - cov nqi hloov pauv. Kev teeb tsa tsis raug ntawm cov khoom siv insulating ua rau cov rwb thaiv tsev tsis ua haujlwm yuav tsum tau kaw rau kev hloov pauv, uas tsis yog tsuas yog cuam tshuam cov nqi txij nkawm tab sis kuj cuam tshuam rau kev ua haujlwm ntawm kab, ua rau tsis ncaj qha. Kev txhim kho meej kom ntseeg tau tias muaj kev ntxhov siab nyob rau hauv lub kaw lus fastening, txo cov khoom qaug zog puas tsuaj, thiab txo cov nqi tag nrho - lub neej tu nqi los ntawm 30% -40%. Yog li ntawd, kev tswj xyuas nruj nruj yuav tsum tau ua thaum lub sijhawm teeb tsa kom tsis txhob muaj qhov tsis tseem ceeb uas ua rau muaj kev poob loj thiab sib npaug ntawm cov nqi siv sijhawm luv luv nrog kev saib xyuas mus sij hawm ntev.
Yuav ua li cas lub voj voog soj ntsuam ntawm lub fastening system yuav tsum tau hloov raws li kab scenarios?
Kev tshuaj xyuas lub voj voog ntawm lub fastening system yuav tsum tau teem sib txawv raws li kab scenarios. Rau siab - cov kab tsheb ciav hlau ceev, vim muaj kev khiav hauj lwm ceev thiab kev ruaj ntseg nruj, lub voj voog soj ntsuam yuav tsum tau luv luv mus rau ib zaug txhua 15 hnub, tsom rau kev kuaj xyuas cov clamping quab yuam ntawm kev tsheb ciav hlau clips thiab ntsia liaj qhov rooj torque. Hnyav- cov kab tsheb thauj khoom muaj cov khoom thauj loj thiab cov khoom siv ceev ceev, yog li lub voj voog tshuaj xyuas yog ib hlis ib zaug, tsom mus rau qhov qaug zog ntawm cov ntses thiab bolts. Kev tsheb ciav hlau hauv nroog tau pib ntau zaus- nres thiab muaj kev vibration hnyav, yog li lub voj voog tshuaj xyuas yog ib zaug txhua 20 hnub, tsom mus rau kev xoob ntawm cov tsheb ciav hlau thiab cov phaj siab. Cov pa ceev railways muaj kev ua haujlwm qis, yog li lub voj voog tshuaj ntsuam tuaj yeem teem caij rau ib zaug txhua 3 lub hlis rau kev tshuaj xyuas niaj hnub ntawm kev ceev ceev. Cov xwm txheej tshwj xeeb xav tau kev tshuaj xyuas hnyav ntxiv; Piv txwv li, nyob rau hauv seem xws li me me - vojvoog nkhaus thiab qhov nkag / tawm, lub voj voog tshuaj xyuas raug txo los ntawm 50% txhawm rau txhawm rau tshawb xyuas qhov ua tsis tiav los ntawm kev ntxhov siab hauv zos.
Yuav ua li cas scientific txiav txim siab hloov lub voj voog ntawm fastening system Cheebtsam?
Lub voj voog hloov ntawm cov khoom siv fastening system yuav tsum tau txiav txim siab raws li cov khoom siv, kab loads, thiab cov ntaub ntawv xeem. Lub voj voog hloov ntawm cov tsheb ciav hlau feem ntau yog 5-8 xyoo; rau hnyav- cov kab tsheb thauj mus los, vim muaj kev puas tsuaj sai sai, nws yuav tsum tau luv luv rau 3-5 xyoo. Alloy steel rail clips siv nyob rau hauv siab - txoj kev tsheb ciav hlau ceev tuaj yeem muaj lawv lub voj voog hloov mus rau 8-10 xyoo. Lub voj voog hloov ntawm bolts muaj feem xyuam rau kev tiv thaiv kev ua haujlwm corrosion: kub-dip galvanized bolts muaj lub voj voog ntawm 6-8 xyoo nyob rau hauv ib puag ncig zoo tib yam, uas yuav tsum tau luv luv rau 3-4 xyoo nyob rau hauv ntug dej hiav txwv corrosive ib puag ncig; bolts nrog Dacromet txheej tuaj yeem muaj lawv lub voj voog hloov mus rau ntau tshaj 10 xyoo. Lub voj voog hloov ntawm cov phaj ntses yuav tsum tau txiav txim siab raws li kev tshawb pom kev tawg-thaum cov kab nrib pleb ntev dua 5 hli tshwm nyob ib ncig ntawm lub qhov ntsia hlau, yuav tsum tau hloov tam sim; tsis muaj kab nrib pleb, lawv tuaj yeem siv rau 8-12 xyoo. Kev hloov lub voj voog ntawm kev tsheb ciav hlau thiab cov phaj siab yog txiav txim siab raws li kev hloov pauv yog xav tau thaum hnav tshaj 20% ntawm qhov loj me, feem ntau 6-8 xyoo.
Yuav ua li cas txo qhov kev pheej hmoo tsis ua hauj lwm ntawm fastening system los ntawm kev tiv thaiv kev saib xyuas?
Kev tiv thaiv kev tiv thaiv yuav tsum tau tsim kom muaj tag nrho - cov ntaub ntawv lub neej voj voog rau cov khoom siv, kaw lub sijhawm teeb tsa, cov khoom siv tshwj xeeb, thiab cov ntaub ntawv xeem kom ua tiav qhov tseeb thiab kev twv ua ntej. Kev siv tshuaj tiv thaiv- xeb tsis tu ncua yuav tsum tau ua ntawm cov ntsia hlau, cov ntsia hlau ntsia hlau, thiab lwm yam khoom siv- tiv thaiv- xeb roj yuav tsum tau siv ib xyoos ib zaug, thiab ib zaug txhua rau lub hlis hauv cov ntug dej hiav txwv kom ncua kev xeb thiab kev laus. Tsis yog-Tsev kuaj kev puas tsuaj (xws li kev kuaj ultrasonic) yuav tsum tau siv los tshuaj xyuas kev ntxhov siab-cov kabmob xws li cov phaj ntses thiab cov phaj siab peb lub hlis twg, tshawb xyuas qhov tsis xws luag hauv lub sijhawm. Rau siab- nrawm thiab hnyav- cov kab tsheb thauj mus los, cov kev vibration soj ntsuam sensors tuaj yeem tsim los sau cov ntaub ntawv tiag tiag- lub sijhawm vibration ntawm cov khoom sib txuas, thiab ceeb toom ntxov ntawm kev pheej hmoo ntawm kev xoob tuaj yeem muab los ntawm kev txheeb xyuas cov ntaub ntawv. Tsis tas li ntawd, yuav tsum tsim kom muaj lub sijhawm saib xyuas lub caij nyoog, xws li ntxiv dag zog rau kev tshuaj xyuas cov khoom siv insulating ua ntej lub caij los nag thiab txhim kho lub zog torque re-tightening ua ntej lub caij ntuj no, kom txo qis kev pheej hmoo ntawm ntau qhov ntev.
Los ntawm qhov ntev npaum li cas tuaj yeem tswj hwm tus nqi ntawm lub fastening system kom paub tseeb?
Kev tswj hwm tus nqi ntawm cov txheej txheem fastening tuaj yeem ua tiav los ntawm peb qhov loj: xaiv, tu, thiab rov ua dua tshiab. Hauv kev xaiv theem, "precision matching" lub hauv paus ntsiab lus yuav tsum tau txais kev pom zoo kom tsis txhob muaj qhov muag tsis pom kev ntawm cov khoom siab - lub zog ua rau cov nqi khib nyiab. Piv txwv li, 8.8- qib bolts yog txaus rau cov pa ceev railways, thiab tsis tas yuav siv 10.9- qib siab- lub zog bolts. Nyob rau theem kev saib xyuas, "qhov xwm txheej-raws li kev saib xyuas" yuav tsum tau txhawb nqa es tsis txhob "kev saib xyuas lub sijhawm"- txiav txim qhov tseeb ntawm cov khoom los ntawm cov ntaub ntawv xeem kom tsis txhob muaj kev hloov ntxov ntawm cov khoom tsis yog{13}} ua tsis tiav thiab txo cov nqi hloov. Kev siv cov khoom siv rov ua dua tshiab thiab rov siv dua yuav tsum raug tsim: kho cov khoom hloov pauv uas tsis muaj kev puas tsuaj loj, xws li kho cov ntsia liaj qhov rooj thiab cov phaj phaj kho vuam, thiab siv rau cov kab thib ob tom qab dhau qhov kev xeem los txhim kho kev siv cov peev txheej. Nyob rau tib lub sijhawm, kev yuav khoom ntawm cov khoom tseem ceeb txo qis cov nqi yuav khoom, thiab kos npe rau daim ntawv cog lus kev koom tes mus sij hawm ntev nrog cov neeg muag khoom kom muaj kev ruaj ntseg ntawm cov khoom siv ntxiv thaum sib zog rau cov nqi luv nqi, ua kom tiav cov txheej txheem tag nrho cov nqi optimization.
