22 kq rwjhnyav 22.3kg ib 'meter' thiab yog tsim rau crane lem, overhead thauj systems, thiab lwm yam kev lag luam teeb uas yuav tsum tau ntau dua load- bearing peev xwm. Cov qauv no txuas qhov sib txawv ntawm lub teeb thiab hnyav rails, haum rau kev siv xws li lub teeb lub luag hauj lwm -gantry cranes los yog thauj hauv kev txiav thiab mining qhov chaw.
Yuav ua li cas rau nruab 22kg rail kom raug?
Kev teeb tsa ntawm txoj kev tsheb ciav hlau yog cov txheej txheem kev tshaj lij uas xav tau qhov tseeb, kev paub dhau los, thiab ua raws li cov qauv kev lag luam nruj.
- Txhawm rau txhim kho 22kg kev tsheb ciav hlau kom zoo, pib los ntawm kev npaj ib qho huv, theem kev txhawb nqa nto thiab tso cov grooved elastic pads rau nws. Ua kom raug qhov chaw ntawm txoj kev tsheb ciav hlau raws li tus qauv tsim thiab qhov siab, kom ntseeg tau qhov sib txawv me me. Rau ib qho seamless tiav, weld seem ua ke siv ib txoj kev zoo li thermite vuam; Yog tias siv cov khoom siv kho tshuab, ruaj ntseg nrog cov ntses thiab bolts, ua kom qhov khoob me me.
- Lub tsheb ciav hlau yog ces fastened nrog ib tug clip system. Tso cov clips kom cov roj hmab tivthaiv hu rau cov tsheb ciav hlau flange. Ntxig bolts nrog lub tshuab ntxhua khaub ncaws thiab pib tes-tighten lawv kom compress lub qhov ntswg roj hmab. Thaum kawg, siv lub calibrated torque ciaj ntswj kom ceev cov txiv ntseej mus rau qhov teev torque, kom muaj kev ruaj ntseg tuav.
- Xaus los ntawm kev sib tsoo cov pob qij txha du, siv los tiv thaiv -corrosion txheej rau machined nto, thiab ua qhov kev tshuaj ntsuam zaum kawg. Qhov kev tshuaj xyuas no yuav tsum xyuas kom meej tag nrho qhov ntev, qhov ncaj, thiab theem ua tau raws li tus qauv tsim qauv ua ntej kev khiav haujlwm.

Dab tsi yog cov yam ntxwv ntawm 22kg steel rail?
A GB 22kg steel rail yog Suav tus qauv, nruab nrab - lub luag haujlwm lub teeb tsheb ciav hlau (kwv yees . 22.3} kg / m) paub txog nws lub zog zoo, hnav tsis kam, thiab ua haujlwm ntev, haum rau kev lag luam, mining, thiab lub teeb tsheb thauj mus los, muab kev nyab xeeb siab, tus nqi- ua tau zoo, thiab feem ntau ua los ntawm Q235 lossis 55Q6 6 3mm qhov siab, nrog rau qhov siab 6 hli, 6 hli dav, 6 hli. tsim los txhim khu kev qha kev ua tau zoo nyob rau hauv nruab nrab loads.
Cov yam ntxwv tseem ceeb:
- Nyhav & Standard: Nyhav ib ncig ntawm 22.3 kg ib 'meter' thiab ua raws li Suav GB qauv (GB/T 11264-2012).
- Khoom siv: Feem ntau ua los ntawm Q235 lossis 55Q carbon steel, muab qhov sib npaug ntawm qhov tawv thiab hnav tsis kam.
