Raws li cov tseem ceeb ntawm cov kab hnyav-cov dej num ntawm 75kg hnyav rails yuav tsum tsom rau kev sib kis kev sib kis kev sib raug zoo thiab cov qauv kev cai. Los ntawm kev kuaj mob kom pom tseeb thiab kev kho mob, nws txoj kev pabcuam lub neej tuaj yeem txuas ntxiv.
Performicic ciav hlau kev soj ntsuam yog lub hauv paus ntawm kev saib xyuas. Txoj kev tsheb ciav hlau ncaj qha yog cov ntawv soj ntsuam txhua hnub nrog kev soj ntsuam cov kev soj ntsuam TEAD Lub xeev ntawm cov txheej txheem quenching ntawm cov tsheb ciav hlau ntawm lub lim hiam ib asthiv, thiab cov npoo hardness yog ntsuas los ntawm cov kws sim siab ({} hbw yog tsim nyog). Yog tias pom qhov muag muag hauv zos, nws yuav tsum tau cim thiab polished.
Lub nrawm nrawm nrawm kev txij nkawm yuav tsum tau ua raws li tib lub sijhawm. Tshawb xyuas cov ntsia liaj qhov rooj ua ntej nruj torque txhua lub hlis. Lub 10. {{9- bolts yuav tsum tau tswj hwm ntawm {3} · m. Thaum rov ua kom nruj nrog cov ciaj ntswj lub zog, ua tib zoo saib cov kab nkhaus thiab cov kab ke los tiv thaiv kev ua kom muaj zog ua ntej los ntawm kev co. Qhov siv lub zog ntawm lub caij nplooj ntoo hlav yog soj ntsuam txhua lub quarter kom paub tseeb tias qhov siv tau yog tswj hwm ntawm {6}} kn. Lub Caij Nplooj Ntoos Hlav (Lub Siab<12kN) need to be replaced immediately to avoid longitudinal creep of the rail.
Kev tsheb taub hau sib tsoo thiab kho yuav tsum tau nqa tawm raws li kev coj txoj cai. Thaum lub tog hnav ntawm cov tsheb ciav hlau ncav cuag 8 hli (ntawm txoj kev nkhaus) lossis 1}}}}}} daim ntawv hla kev ntawm cov ciav hlau. Rau cov ntses nplai tawg uas tau tshwm sim, kev sib tsoo hauv zos yuav tsum tau tshem tawm cov ntsiab lus ntxhov siab. Lub saum npoo av ntxhib tom qab sib tsoo yuav tsum tsawg dua los yog sib npaug rau 12.5μm.
The maintenance of the rail bottom and rail waist cannot be ignored. Check the contact status between the rail bottom and the pad every six months, remove foreign matter to avoid local stress concentration; perform magnetic particle inspection on the rail waist bolt hole, and if cracks (length >3 hli) pom, lub qhov yuav tsum tau nthuav dav lossis cov tsheb ciav hlau luv luv yuav tsum tau hloov tsheb luv. Cov tsheb ciav hlau ntsuas qhov kub yuav tsum tau saib xyuas kab kab uas yuav tsum tau saib xyuas txhua hli. Thaum qhov sib txawv ntawm tus ciav hlau tiag tiag thiab lub xauv qhov ntsuas kub tshaj ± 10 degree yuav tsum tau hloov kho lossis kev ntxhov siab ntau dhau ntawm kev ntxhov siab.
Los ntawm kev saib xyuas zoo, lub neej qaug zog ntawm 75kg Hnyav rau ntau dua 30 lab tag nrho cov khoom lag luam thiab kev txij nkawm cov nqi ntawm hnyav-thauj cov kab.
Gnee RailTsom rau cov ntshuam thiab export ntawm GB txheem txheem. Ntxiv nrog rau kev sib tw hnyav, peb cov khoom tseem ceeb suav nrog cov ciav hlau teeb, uas tau siv dav hauv kev tsheb ciav hlau, kev tsheb ciav hlau hloov chaw, chaw nres nkoj Machinery thiab lwm thaj chaw.
Cia siab rau ntawm cov khoom siv tau ruaj khov thiab kev sib koom ua ke steel mills, peb xa peb cov khoom lag luam thiab cheeb tsam teb chaws nyob rau sab hnub tuaj thiab cov kev pab sib tw thiab cov kev pabcuam zoo.
Peb ua raws li qhov ua tau zoo ua ntej, muab cov kev hloov pauv hloov kho yooj yim thiab cov khoom lag luam txhim khu kev qha thiab kev txhawb nqa ntiaj teb kev tsim kho.
