I-Tungsten Carbide bearings: Isisombululo esiphezulu soMsebenzi oPhezulu wokuSebenza kweMisebenzi

Kwindawo yoomatshini boshishino, iibheringi zisebenza njengeumqoloyokusebenza kakuhle, kodwa ayizizo zonke iibheringi ezenziwe ngokulinganayo.Iibheringi zeTungsten carbideziye zavela njengomtshintshi-mdlalo, umnikeloukuqina kunye nokusebenza okungenakulinganiswaoko kugqwesa izinto zemveli njengentsimbi okanye i-ceramic. Idityaniswe netungsten carbide-intlanganisela ye-tungsten kunye nekhabhoni edume ngobulukhuni bayo obugqithisileyo (yesibini kuphela kwidayimane) kunye nokuchasana nokunxiba-ezi bheringi zenzelwe ukuba zikhule kakuhle.iindawo ezinzima kakhulu,ukwenza ukuba zibe yimfuneko kuwo wonke amashishini angundoqo.

Enye yezona zinto ziluncedo kakhulu kwi-tungsten carbide bearings yazoubulukhuni obukhethekileyo, ilinganiswe kwi-90-95 HRA (i-Rockwell Hardness Scale). Le propati ibenza bakwazi ukuukumelana nemithwalo enzima, isantya esiphezulu, kunye namasuntswana abrasivengaphandle kokuguqula okanye ukuwohloka, uphawu olubalulekileyo kumacandelo afana nemigodi, i-oyile kunye negesi, kunye nemveliso. Kwimisebenzi yezimayini, umzekelo, ii-tungsten carbide bearings system conveyor power systems kunye ne-crushers, ukunyamezela ukukhuhlana okuqhubekayo ukusuka kwiidiphozithi zamaminerali kunye nothuli olunzima. Kwishishini leoli kunye negesi, bagqwesa kwizixhobo zokugaya i-downhole, apho baxhathisa ukubola kwi-acidic fluids kunye nokugcina ingqibelelo phantsi koxinzelelo olunzima (ukuya kwi-10,000 psi) kunye namaqondo okushisa (adlula i-300 ° C). Ngokungafaniyo neebheringi zentsimbi, ezihlala zifuna ukutshintshwa rhoqo ngenxa yokunxiba, ukwahluka kwe-tungsten carbide kuqhayisa ubomi obude ukuya kuthi ga kwi-10 ubude, kuncitshiswe kakhulu iindleko zokulondolozwa kunye nexesha lokuphumla kumashishini.

Olunye uncedo oluphambili ngaboukuxhathisa okuphezulu kwe-corrosion. Iibheringi zentsimbi zemveli ziqhelene nokugqwala kunye nokuthotywa xa zivezwe kukufuma, iikhemikhali, okanye amanzi etyuwa, kodwa indalo engasebenziyo ye-tungsten carbide iyayikhusela kumonakalo onjalo. Oku kuzenza zibe zilungele ukusetyenziswa elwandle, njengeeshafti zepropeller kunye neempompo zangaphantsi kwamanzi, kunye nezityalo zokulungiswa kweekhemikhali apho iibheringi zidibana nezinyibilikisi ezidliwayo. Ukongezelela, i-coefficient yabo ephantsi ye-friction iqinisekisa ukujikeleza kakuhle nakwisantya esiphezulu, ukunciphisa ukulahlekelwa kwamandla kunye nokuphucula ukusebenza kakuhle koomatshini-into ebalulekileyo kumashishini azama ukunciphisa i-carbon footprints kunye neendleko zokusebenza.

Ngelixa iibheringi ze-tungsten carbide zibonelela ngokusebenza okumangalisayo, zabouyilo kunye nofakelozifuna ukuchaneka. Abavelisi bahlala belungelelanisa usetyenziso oluthile, uhlengahlengiso lwezinto ezinje ngokucocwa, ukugquma (umzekelo, ikhabhoni efana nedayimane yokuthambisa okongeziweyo), kunye nohlobo lwesitywina sokwandisa ukusebenza. Ukugcinwa okufanelekileyo, okufana nokuthambisa rhoqo ngeegrisi ezinobushushu obuphezulu, kwandisa ubomi babo benkonzo.

Njengoko amashishini eqhubeka nokutyhala imida yesantya, umthwalo, kunye nokomelela kokusingqongileyo, iibheringi ze-tungsten carbide zikulungele ukudlala indima ebaluleke ngakumbi. Ukusuka kwiirobhothi zokwenziwa phambili ukuya kwizixhobo zamandla ahlaziyekayo njengejenereyitha ye-injini yomoya, ukukwazi kwabo ukudibanisa ukuqina, ukuxhathisa umhlwa, kunye nokuphila ixesha elide kubenza bakhethe ukukhetha iinjineli ezifuna izisombululo ezithembekileyo nezisebenza kakhulu. Kwihlabathi apho ukusebenza komatshini kunye nokuqina kuchaphazela ngokuthe ngqo imveliso kunye nenzuzo, iibheringi ze-tungsten carbide zime njengobungqina bendlela.izinto ezintsha zinokuguqula imisebenzi yoshishino.
