Hauv kev ua haujlwm hnyav xws li mining metallurgy, chaw nres nkoj nqa, thiab cov tshuab hnyav, kev lag luam nres yog qhov tseem ceeb ntawm kev nyab xeeb, thiab lawv cov kev xaiv xaiv ncaj qha txiav txim siab txog kev ruaj ntseg thiab kev nyab xeeb ntawm cov khoom siv. Tsis zoo li lub teeb thauj khoom lossis kev ua haujlwm ib txwm ua, cov xwm txheej hnyav hnyav yuav tsum tau pib thiab nres ntawm cov khoom siv, kev cuam tshuam tseem ceeb, thiab kev ua haujlwm nyuaj, uas tso cai nruj rau kev ua haujlwm ntawm cov brakes. Raws li cov kws tshaj lij kev lag luam koom nrog hauv kev lag luam braking ntau xyoo, peb tau sau cov ntsiab lus ntawm peb qhov tseem ceeb rau kev xaiv nres nyob rau hauv cov xwm txheej hnyav raws li qhov loj ntawm qhov kev ua tau zoo - load, kub, thiab zaus.
Raws li qhov sib txuam load tsis, tsim thawj kab ntawm kev tiv thaiv kev nyab xeeb
Load yog qhov tseem ceeb tshaj plaws rau kev xaiv nres nyob rau hauv cov xwm txheej hnyav, uas cuam tshuam ncaj qha rau lub peev xwm ntawm kev sib tsoo lub zog thiab kev ntseeg siab ntawm cov khoom siv braking. Kev thauj khoom hnyav - cov khoom siv ua haujlwm tsis yog ib qho nqi tas li, feem ntau suav nrog ntau yam kev ua haujlwm xws li cov khoom ntsuas ntsuas, qhov siab tshaj plaws, thiab kev cuam tshuam. Thaum xaiv, kev txiav txim siab yuav tsum tau muab rau kom tsis txhob muaj teeb meem tsis tsim nyog.
Rau qhov ntsuas load, nws yog ib qho tsim nyog los xyuas kom meej tias qhov ntsuas lub zog ntawm lub nres ua tau raws li qhov yuav tsum tau ua ntawm cov khoom siv hauv kev ua haujlwm zoo li qub thiab ceev ceev, nrog rau kev nyab xeeb ntawm tsis pub tsawg dua 20% tshwj tseg los tiv thaiv kev hloov pauv sai. Hauv cov xwm txheej uas muaj kev cuam tshuam, xws li thaum muaj xwm txheej ceev ntawm cov mining hoists thiab nqa hnyav thiab txo qis ntawm cov chaw nres nkoj cranes, tus nres yuav tsum muaj kev tiv thaiv kev cuam tshuam thiab kev ua haujlwm ntau dhau. Thaum xaiv, kev siv yuav tsum tau ua kom muaj kev cuam tshuam ntau tshaj plaws ntawm cov khoom siv, thiab cov khoom uas muaj siab - cov ntaub ntawv muaj zog sib txhuam thiab cov qauv nres nres yuav tsum raug xaiv los tiv thaiv kev nyab xeeb xws li nres tsis ua haujlwm thiab cov khoom tawg los ntawm kev cuam tshuam.
Nyob rau tib lub sijhawm, hom kev thauj khoom kuj tseem cuam tshuam rau kev xaiv cov kev taw qhia. Rau cov khoom siv nrog cov khoom zoo li qub raws li lub ntsiab thauj khoom, xws li hnyav- lub luag haujlwm khaws cia stackers, yuav tsum tau muab tso rau ntawm qhov chaw nres tsheb zoo li qub; Rau cov khoom siv uas muaj kev cuam tshuam tsis tu ncua, xws li metallurgical dov mills, qhov tseem ceeb yuav tsum tau muab rau xaiv hom nres nrog cov lus teb ceev ceev thiab ruaj khov torque tso zis.
Hloov mus rau qhov kub thiab txias ib puag ncig thiab xyuas kom ruaj khov kev ua haujlwm tso zis
Nyob rau hauv cov xwm txheej hnyav, lub sijhawm ua haujlwm siab ntawm cov khoom siv, ua ke nrog qhov sib txawv ntawm qhov chaw ua haujlwm, tuaj yeem yooj yim ua rau muaj kev sib txhuam ntawm cov phaj txhuam thiab thermal expansion deformation ntawm cov khoom nres, yog li cuam tshuam rau cov nyhuv braking. Yog li ntawd, qhov kub thiab txias adaptability yog ib qho tseem ceeb hauv kev xaiv hnyav - lub luag haujlwm nres.
Qhov kub thiab txias ib puag ncig yog ib qho nyuaj rau kev ua haujlwm hnyav, xws li kev cob qhia steelmaking hauv kev lag luam metallurgical, qhov twg qhov kub ntawm ib puag ncig tuaj yeem ncav cuag 60℃. Thaum lub sij hawm nruam braking txheej txheem ntawm tus nres, lub tshav kub generated los ntawm kev sib txhuam ntawm cov phaj txhuam thiab cov brake disc yuav ntxiv nws tus kheej kub. Yog hais tias qhov kub siab tshaj qhov siab tshaj qhov kev txwv ntawm tus nres, yuav muaj qhov tshwm sim ntawm "thermal degradation" nyob rau hauv uas cov kev sib txhuam coefficient txo thiab lub braking torque decays, hnyav hem cov cuab yeej kev nyab xeeb. Thaum xaiv, qhov tseem ceeb yuav tsum tau muab rau cov brakes ua los ntawm siab -cov ntaub ntawv sib txhuam kub, xws li ceramic raws li kev sib txhuam pads, uas muaj qhov zoo dua siab dua - kub tsis kam tshaj li cov khoom siv los ntawm cov khoom siv thiab cov thermal stability; Nyob rau tib lub sijhawm, xyuam xim rau cov qauv cua txias tsim ntawm tus nres, xws li cov khoom nruab nrog cov kiv cua txias thiab cov fins, uas tuaj yeem ua kom cov cua sov dissipation thiab tswj kev ua haujlwm ruaj khov.
Nyob rau hauv qis - kub thiab siab - qhov chaw siab, xws li qhib- qhov mines nyob rau sab qaum teb thiab cov khoom siv hluav taws xob, qhov kub tsis tshua muaj peev xwm ua rau muaj qhov nce ntxiv ntawm cov roj hydraulic, hardening thiab shrinkage ntawm cov roj hmab ntsaws ruaj ruaj, cuam tshuam cov lus teb ceev thiab sealing kev ua tau zoo ntawm tus nres. Thaum xaiv, nws yog ib qho tsim nyog yuav tsum xaiv qhov qis- qhov kub thiab txias adaptive nres, nruab nrog qis- kub resistant hydraulic roj thiab cov ntsaws ruaj ruaj, kom ntseeg tau tias tus nres tseem tuaj yeem pib thiab nres tau yooj yim yam tsis muaj teeb meem cuam tshuam lossis xau teeb meem hauv qhov tsis tshua muaj siab - qhov kub thiab txias ntawm -40℃.
Xav txog qhov yuav tsum tau ua ntawm braking zaus thiab txuas ntxiv lub neej ntawm cov khoom siv
Nyob rau hauv cov xwm txheej hnyav, lub braking zaus ntawm cov cuab yeej sib txawv heev. Piv txwv li, lub braking zaus ntawm qhov chaw nres nkoj thawv cranes tuaj yeem ncav cuag ntau lub sijhawm hauv ib teev, thaum lub sijhawm braking ntawm cov mining loj crushers kuj tsawg. Lub braking zaus cuam tshuam ncaj qha rau kev hnav tus nqi thiab kev pabcuam lub neej ntawm tus nres, thiab yog qhov tseem ceeb uas tsis tuaj yeem tsis quav ntsej thaum xaiv.
Rau siab - cov khoom siv braking zaus, lub hauv paus ntawm kev xaiv yog los txhim kho qhov hnav tsis kam thiab qaug zog tiv thaiv ntawm tus nres. Ntawm ib sab, nws yog ib qho tsim nyog yuav tau xaiv cov ntaub ntawv sib txhuam cov ntaub ntawv nrog kev hnav siab kom txo tau qhov poob los ntawm kev sib txhuam tsis tu ncua; Ntawm qhov tod tes, qhov tseem ceeb yuav tsum tau muab rau kev siv cov khoom lag luam nres nrog cov qauv tsim thiab kev saib xyuas yooj yim, uas ua kom yooj yim hloov cov phaj sib txhuam hauv cov theem tom qab thiab txo cov khoom siv downtime. Tsis tas li ntawd, siab - zaus braking tuaj yeem ua rau qaug zog kev puas tsuaj rau cov khoom siv braking, yog li nws yuav tsum tau ua tib zoo saib xyuas lub zog ntawm tus nres thiab xaiv cov khoom uas tau dhau los ua lub zog qaug zog kom tsis txhob muaj cov khoom tawg los ntawm qhov ntev - lub sij hawm siab - zaus braking.
Rau cov khoom siv nrog tsawg - zaus braking tab sis siab ib leeg braking load, xws li thaum muaj xwm ceev braking systems rau loj choj cranes, kev xaiv yuav tsum tsom rau lub instantaneous torque tso zis muaj peev xwm thiab kev cia siab ntawm tus nres, kom ntseeg tau tias nyob rau hauv tsawg- zaus thiab siab load braking scenarios, ib tug braking muaj peev xwm ua tau ib tug ruaj khov kev txiav txim siab ntawm cov khoom, thiab thaum lub sij hawm ncua kev cuam tshuam ntawm cov khoom siv. kev pabcuam lub neej.
Raws li cov neeg siv khoom xav tau, muab cov kev daws teeb meem customized
Lub complexity ntawm hnyav-lub luag hauj lwm ua hauj lwm tej yam kev mob txiav txim siab hais tias kev xaiv ntawm industrial brakes tsis tuaj yeem yog ib qho me me haum rau txhua txoj hauv kev, thiab yuav tsum tau txiav txim siab zoo raws li cov xwm txheej ua haujlwm tshwj xeeb thiab cov khoom siv tsis raug. Raws li cov kws tshaj lij kev lag luam nres tsheb, peb tsis tsuas yog muab cov khoom lag luam txheem npog ntau yam kev thauj khoom, qhov kub thiab txias, thiab zaus, tab sis kuj muab cov kev hloov kho braking kev daws teeb meem raws li cov neeg siv khoom xav tau. Los ntawm kev tshawb fawb txog kev ua haujlwm ua ntej thiab kev ntsuas ntsuas, mus rau nruab nrab - lub sij hawm xaiv cov khoom lag luam thiab cov txheej txheem kev ua kom zoo, mus rau tom qab kev teeb tsa, kev debugging, thiab tom qab- kev muag khoom, peb muab kev txhawb nqa tag nrho rau peb cov neeg siv khoom thiab pab kev nyab xeeb thiab ua haujlwm zoo ntawm cov khoom hnyav - lub luag haujlwm.
Nyob rau hauv lub neej yav tom ntej, peb yuav txuas ntxiv rau kev cog qoob loo ntawm qhov hnyav- lub luag haujlwm braking, uas tau tsav los ntawm kev tsim kho thev naus laus zis, txuas ntxiv txhim kho kev ua tau zoo thiab hloov tau ntawm peb cov khoom, thiab muab siab - cov khoom lag luam braking zoo thiab cov kev pabcuam rau ntau tus neeg siv khoom lag luam.
