Izinga lokushisa langempela lokusebenza komuntu ongenzi lutho kufanele libe phansi kunephuzu lokwehla lika-10-20 degrees centigrade.Izinga lokushisa lokusebenzisa amafutha okwenziwa lizoba ngaphansi kwephuzu lokulahla ama-20-30 centigrade.Lokhu kungenxa yokukhethwa kwamafutha ngokuhambisana nezinga lokushisa elisebenzayo lama-bearings avaliwe, izinkomba eziyinhloko kufanele kube iphuzu lokudonsa, ukuzinza kwe-oxidation kanye nokusebenza okuphansi kwezinga lokushisa, indawo yokulahla ngokuvamile ingasetshenziselwa ukuhlola izinga lokushisa eliphezulu.
I-roller ethwele umthwalo khetha amafutha, amafutha omthwalo osindayo kufanele akhethwe ukungena okuncane.Lapho isebenza ngaphansi kwengcindezi ephezulu, ngaphandle kokungena okuphezulu, iphinde ibe namandla aphezulu efilimu kawoyela nokusebenza kokucindezela okukhulu.Uma amafutha ekhethwa ngokuvumelana nezimo zemvelo, i-calcium esekelwe igrisi ayincibiliki emanzini futhi ifanele ukomiswa kanye nomswakama omncane.Ngakho-ke ama-roller okuthutha amakhwalithi amahle abaluleke kakhulu.
Impilo yesevisi ye-roller incike ikakhulukazi ekusebenzeni kokuthwala nokufaka uphawu.Uma ukusebenza kwe-roller nokufaka uphawu kuhle, impilo yesevisi ye-roller izokwelulwa kakhulu.Imiphumela yokuhlolwa ibonisa ukuthi ukumelana nokungqubuzana kwe-Yuezhantuo roller rotary ene-1/4~1/8.Ngakho-ke, ukukhetha amafutha amahle kubaluleke kakhulu ekunciphiseni ukumelana kwe-roller bear.Ikhwalithi enhle ye-conveyor rollers ibaluleke kakhulu isikhathi eside sokusetshenziswa.
Ukukhetha okungalungile kwamafutha kuzodala umonakalo ekuthwaleni, okuzoholela ekulimaleni kovila.I-MT821-2006 izinga lemboni yamalahle lidinga ngokusobala ukukhethwa kwegrisi engu-3#, umenzi okufanele ahambisane nayo.Uma kungenjalo, i-roller izolimala ngemva kwamahora ambalwa egijima.Okugcizelelwa lapha ukuthi, kuma-bearings angasebenzi ngaphansi kwezimo zokusebenza ze--25, uhlobo olukhethekile lwamafutha ezindiza angamelana nokushisa okuphansi kufanele kukhethwe.
Lokhu kuwumkhuba okhuphukayo wentengo yamalahle ngenxa yokufika kwezinsuku zezinja futhi kushisa kakhulu.Ngesonto eledlule, izwe lingenise inqwaba yamazinga okushisa aphezulu, ukwanda kwesidingo sikagesi, ukuphehlwa kukagesi ezweni sekuphezulu okusha, nokuholele ekuqhubekeleni phambili kokuhlinzeka ngamalahle.Futhi phakathi no-7 ngasekupheleni, amazinga okushisa aphezulu azoqhubeka, isidingo samalahle sizokhuphuka. Ehlangothini lokuhlinzeka kusenezimo eziqinile, umfutho ohlangothini lwesidingo kulindeleke ukuthi ukhulise imakethe futhi.
Ezinsukwini ezimbalwa ezedlule, izinga lokunikezwa kwamandla kunethiwekhi yonke belilokhu likhuphuka ngokuqhubekayo ngenxa yethonya lohlu olukhulu lwesimo sezulu esishisayo esiqhubekayo.Kusukela mhla ziyi-11 kuNtulikazi kuya mhla ziyi-13 kuNtulikazi, amandla okuphehla ugesi wezwe afinyelele irekhodi eliphezulu, akhuphuke ngama-7% ukusuka esiqongweni sawo ehlobo eledlule.I-Beijing, i-Tianjin, i-Hebei kanye nezinye izifunda ezingu-12 zegridi yamandla zifinyelele irekhodi eliphezulu.Njengoba isidingo samalahle besinamandla, amanani amalahle anyuke kancane kusukela maphakathi noJuni.Ngenxa yesimo sezulu esishisayo esiqhubekayo, amanani amalahle kulindeleke ukuthi anyuke.Nakuba i-NDRC isigcizelele isidingo sokwandisa ukuhlinzekwa kwamalahle, kodwa ngokufika kwenkathi yasehlobo ephakeme kakhulu, isidingo samalahle sinyukile, ukuhlinzekwa kwamalahle kusaqinile.
