Overhead Crane Rail Vuam Cov Lus Qhia
Nyob rau hauv cov txheej txheem welding rau overhead crane ntsia, nws yog ib qho tseem ceeb rau welding txhua txheej ntawm rail welding yoj siv electrodes nyob rau hauv qab. Tsis txhob arc tawg nyob rau hauv nruab nrab ntawm cov electrodes yog ib qho tseem ceeb rau ib tug seamless vuam txheej txheem. Tom qab ua tiav cov nyiaj siv ua haujlwm crane rail welding, kev kho cua sov yuav tsum tau ua ua ntej ua kom txias, ua kom muaj kev tiv thaiv los nag lossis ntub dej. Kev hais txog cov kab mob ntau dhau hauv cov vuam yuav tsum koom nrog kev sib tsoo nrog lub log kom txog thaum yaug nrog lub taub hau tsheb ciav hlau, ua raws li kev polishing nto.
Clarity nyob rau hauv cov kev taw qhia ntawm lub overhead crane khiav yog qhov tseem ceeb rau kev tswj crane khiav lag luam. Yuav kom ua tiav qhov no, cov nyiaj siv ua haujlwm crane rail yuav tsum tau taw qhia kom meej rau hauv ib qho kev taw qhia tshwj xeeb.
Thaum koom nrog ob ntu ntawm cov nyiaj siv ua haujlwm crane rail, tso cai rau 1-2mm seams feem ntau tau txais. Nyob rau hauv qhov chaw txias dua los yog piv txwv qhov kev teeb tsa chav tsev kub sib txawv ntau dua 20 degrees, kev txiav txim siab rau thermal expansion thiab contraction yuav tsum yog nruab nrab. Hauv cov xwm txheej zoo li no, qhov sib txawv ntawm 4-6mm ntawm qhov sib koom ua ke ntawm ob qhov nyiaj siv ua haujlwm crane rail tau pom zoo. Lub kaum sab xis sib koom tuaj yeem yog txoj cai lossis inclined ntawm 45 degrees, ua kom yooj yim lub log txav ntawm qhov sib koom ua ke. Qhov sib txawv ntawm qhov sib txawv thiab qhov siab qhov sib txawv ntawm ob qhov kev tsheb ciav hlau ntawm qhov kev sib tshuam yuav tsum tsis pub tshaj 1 hli. Thaum lub sij hawm welding txheej txheem, ib ntus clamps yog pom zoo los kho cov crane ntsia kom yooj yim vuam.
