Ubushushu bokusebenza bomntu ongasebenziyo buyakuba ngaphantsi kweqondo lokuhla nge-10-20 degrees centigrade.Ukushisa kokusetyenziswa kwegrisi yokwenziwa kuya kuba ngaphantsi kwendawo yokulahla i-20-30 centigrade. Oku kungenxa yokukhethwa kwegrisi ngokuhambelana nokushisa okusebenzayo kweebheringi ezitywiniweyo, izikhombisi eziphambili kufuneka zibe yindawo yokulahla, ukuzinza kwe-oxidation kunye nokusebenza kweqondo lokushisa eliphantsi, indawo yokulahla ingasetyenziselwa ukuvavanya ubushushu obuphezulu bokusebenza.Ngoko ukukhetha igrisi elungileyo kubaluleke kakhulu kwiirola zokuhambisa ezisemgangathweni.
Ukuthwala umthwalo we-roller khetha igrisi, igrisi yomthwalo onzima kufuneka ikhethwe ukungena kuncinci.Xa usebenza phantsi koxinzelelo oluphezulu, ngaphandle kokungena okuphezulu, ikwanamandla aphezulu efilimu yeoli kunye nokusebenza koxinzelelo olugqithisileyo.Xa igrisi ikhethwa ngokweemeko zokusingqongileyo, igrisi esekelwe kwi-calcium ayinyibiliki emanzini kwaye ifanelekile ukomiswa kunye nomswakama ongaphantsi.Ngoko ke ii-rollers zokuhambisa ezisemgangathweni zibaluleke kakhulu.
Ubomi benkonzo ye-roller buxhomekeke ngokukodwa ekusebenzeni kokuthwala kunye nokutywinwa.Ukuba ukuthwala kunye nokutywinwa kokusebenza kwe-roller kulungile, ubomi benkonzo ye-roller buya kwandiswa kakhulu.Iziphumo zovavanyo zibonisa ukuba ukuxhathisa i-friction ye-Yuezhantuo roller rotary ephethe i-1/4 ~ 1/8.Ngoko ke, ukukhetha igrisi elungileyo kubaluleke kakhulu ekunciphiseni ukuxhathisa i-roller bearing.Ii-roller ze-conveyor ezisemgangathweni zibaluleke kakhulu kwixesha elide lokusetyenziswa.
Ukukhethwa okungafanelekanga kwegrisi kuya kubangela umonakalo kwi-bearing, eya kubangela umonakalo kwi-idler.I-MT821-2006 umgangatho woshishino lwamalahle ufuna ngokucacileyo ukhetho lwe-3 # igrisi, umenzi kufuneka athobele.Ngaphandle koko, i-roller iya konakala emva kweeyure ezimbalwa zokusebenza.Into egxininiswe apha kukuba, kwiibherethi ze-idler phantsi kweemeko zokusebenza ze-25, uhlobo olukhethekileyo lwegrisi ye-aviation ephantsi kweqondo lokushisa kufuneka ikhethwe.
Lo ngumkhuba wokunyuka kwamaxabiso amalahle ngenxa yokufika kweentsuku zezinja kwaye kushushu ngakumbi.Kwiveki ephelileyo, ilizwe lingenise uluhlu olukhulu lobushushu obuphezulu, imfuno yombane inyukile, ukuveliswa kombane weli lizwe kukwinqanaba eliphezulu elitsha, nalo elikhokeleyo. ukuya kubonelelo oluqhubekayo lwe-tight yamalahle.Kwaye phakathi emva kwexesha lesi-7, amaqondo obushushu aphezulu aya kuqhubeka, imfuno yamalahle iya kwanda. Kwicala lonikezelo kusekho iimeko ezixineneyo, umfutho wecala lemfuno kulindeleke ukuba unyuse imarike kwakhona ngaphezulu.
Kwiintsuku ezimbalwa ezidlulileyo, inqanaba lonikezelo lwamandla enethiwekhi yonke liye lanyuka ngokuqhubekayo ngenxa yempembelelo yoluhlu olukhulu lobushushu obuphezulu obuqhubekayo.Ukususela ngomhla we-11 kweyeKhala ukuya kowe-13 kaJulayi, umthamo wokuvelisa umbane welizwe ufikelele kwirekhodi eliphezulu, unyuke nge-7% ukusuka kwincopho yawo yehlobo elidlulileyo.I-Beijing, i-Tianjin, i-Hebei kunye nezinye i-12 umthwalo wegridi yamandla wephondo ufikelele kwirekhodi eliphezulu.Ngemozulu eshushu eqhubekayo, amaxabiso amalahle nawo kulindeleke ukuba anyuke.Nangona i-NDRC iye yagxininisa imfuneko yokwandisa unikezelo lwamalahle, kodwa ngokufika kwencopho yexesha lasehlotyeni, imfuno yamalahle inyukile, ukubonelelwa kwamalahle kusenzima.
