1. Txoj kev tsheb ciav hlau ua haujlwm li cas hauv cov cheeb tsam uas muaj kev kub ntxhov siab (piv txwv li, tshauv poob)?
Volcanic tshauv yog heev abrasive thiab corrosive (vim acidic Cheebtsam), ua puas clamps. Clamps nyob rau hauv cheeb tsam volcanic siv cov cua sov-resistant, acid{2}}cov pov thawj coatings (xws li, npib tsib xee-chromium alloys) thiab yog tsim los rau kev tu yooj yim. Kev tshem tawm tshauv yog ua tiav tas li siv siab - cov dej siab los yog txhuam kom tsis txhob muaj cov khoom uas tuaj yeem cuam tshuam cov khoom txav. Tom qab kev tawg, cov clamps raug tshuaj xyuas rau kev puas tsuaj thaum tshav kub kub thiab corrosion, nrog rau kev hloov ntawm cov kev cuam tshuam loj heev. Lawv cov qauv tsim ua ntej tseem ceeb rau kev yooj yim, zam qhov tsis sib xws uas cov tshauv tuaj yeem sib sau ua ke, kom ntseeg tau tias lawv tseem ua haujlwm txawm tias nyob hauv cov xwm txheej volcanic.
2. Lub luag haujlwm ntawm txoj kev tsheb ciav hlau ua haujlwm li cas hauv kev ruaj ntseg ntawm kev tsheb ciav hlau hloov thiab kev hla?
Hloov thiab hla (qhov twg lem diverge) yuav tsum tau clamps los tuav lub zog dynamic los ntawm lub tsheb ciav hlau log hloov kev taw qhia. Clamps ntawm no yog me me thiab hloov tau yooj yim kom haum raws li kev tsheb nqaj hlau txav thaum lub sij hawm hloov, thaum tseem tswj kev sib tw. Lawv tau sib cais kom ruaj ntseg luv luv rail seem, tiv thaiv kev tsis ncaj ncees uas tuaj yeem ua rau derailment. Tshwj xeeb clamps rau cov keyboards tso cai rau txoj kev tsheb ciav hlau zoo thaum tiv thaiv lub zog sab nraud, kom ntseeg tau tias muaj kev hloov pauv tau zoo. Lawv cov qauv tsim sib npaug qhov yooj yim thiab ruaj khov, tseem ceeb rau kev nyab xeeb kev ua haujlwm ntawm cov txheej txheem taug qab no.
3. Yuav ua li cas railway clamps cuam tshuam nrog txoj kev stabilization systems (xws li, av ntsia hlau, geogrids) nyob rau hauv tsis muaj zog subgrade cheeb tsam?
Nyob rau hauv tsis muaj zog subgrades, khiav stabilization systems (xws li, geogrids) txhawb lub hauv paus, thiab clamps ua hauj lwm nrog lawv mus faib loads. Clamps ruaj ntseg rails rau cov neeg pw tsaug zog, uas hloov qhov hnyav mus rau qhov ruaj khov subgrade, tiv thaiv kev sib haum xeeb tsis sib xws. Lawv yog spaced kom ua raws li stabilization system Cheebtsam, kom ntseeg tau tias load yog faib nyob rau hauv lub reinforced cheeb tsam. Nyob rau hauv lem, lub stabilized subgrade tiv thaiv pw tsaug zog zog, txhim khu lub tuav tuav. Qhov kev sib koom tes no ua kom tag nrho cov kab ke khiav (los ntawm clamps mus rau subgrade) ua haujlwm ua ke kom muaj kev ruaj ntseg hauv cov av nyuaj.
4. Dab tsi yog qhov txawv ntawm kev tsheb ciav hlau clamp txij nkawm rau hluav taws xob vs. tsis yog -electrified lem?
Electrified lem yuav tsum tau clamps nrog insulating Cheebtsam (xws li, yas bushings) los tiv thaiv hluav taws xob tam sim no, ntxiv cov kauj ruam txij nkawm los xyuas cov rwb thaiv tsev ncaj ncees. Clamps nyob ze ntawm cov khoom siv hluav taws xob raug tshuaj xyuas rau kev puas tsuaj los ntawm arcing lossis hluav taws xob tawm, nrog cov txheej txheem kho kom muaj kev rwb thaiv tsev. Tsis yog -electrified lem tsom rau cov neeg kho tshuab hnav thiab corrosion, nrog kev saib xyuas lub hauv paus ntawm kev ntsuam xyuas nruj thiab tshem tawm xeb. Electrified clamps tuaj yeem siv tsis yog -cov txheej txheem txheej, thaum tsis yog- cov khoom siv hluav taws xob tseem ceeb ua ntej cov txheej txheem steel. Ob leeg yuav tsum tau xyuas kom nruj tsis tu ncua, tab sis hluav taws xob clamps muaj kev tshuaj xyuas hluav taws xob ntxiv.
5. Txoj kev tsheb ciav hlau yuav ua li cas thiaj li daws tau qhov kev ntxhov siab los ntawm cov tsheb ciav hlau nqa cov khoom phom sij (xws li, tshuaj, roj)?
Cov tsheb ciav hlau nrog cov khoom siv phom sij yuav tsum tau clamps kom ua tau raws li cov qauv kev nyab xeeb nruj, vim tias derailments tuaj yeem ua rau nchuav. Clamps ntawm no yog ntxiv- ua haujlwm tau ntev, siv 12.9- qib steel thiab rov ua dua qub (piv txwv li, ob lub bolts) los tiv thaiv kev ua tsis tiav. Lawv raug tshuaj xyuas ntau zaus (ib lub lim tiam) rau cov cim ntawm kev hnav, nrog rau kev hloov tam sim ntawm ib qho chaw puas. Lawv cov qauv tsim txo qis qhov phom sij (piv txwv li, cov khoom tsis yog hlau) kom tsis txhob cuam tshuam cov khoom phom sij. Los ntawm kev ua kom muaj kev ruaj ntseg ntawm kev tsheb ciav hlau, cov clamps no yog txheej txheej kev nyab xeeb tseem ceeb hauv kev thauj khoom txaus ntshai.
