Ndingabulinganisela Njani Uburhabaxa boMphezulu?
Ungabala uburhabaxa bomphezulu ngokulinganisa iavareji yeencopho zomhlaba kunye neentlambo kulo mphezulu. Umlinganiselo udla ngokubonwa njenge 'Ra,' nto leyo ethetha 'Uburhabaxa buphakathi.' Ngelixa uRa uluncedo kakhulu kwiparameter yokulinganisa. Kwakhona kunceda ukumisela ukuthotyelwa kwemveliso okanye inxalenye kunye nemigangatho eyahlukeneyo yoshishino.
Ukwenza oku kwenzeka ngokuthelekisa neetshathi zokugqiba umphezulu.
Yintoni eyahlula i-Ra kunye ne-Rz kwiTshati yoburhabaxa boMphezulu?
I-Ra ngumlinganiselo wobude obuphakathi obuphakathi kweencopho kunye neentlambo. Ikwalinganisa ukutenxa kumgca ophakathi kumphezulu ngaphakathi kobude besampulu.
Kwelinye icala, i-Rz inceda ukulinganisa umgama othe nkqo phakathi kweyona ntlambo iphakamileyo kunye neyona ntlambo isezantsi. Ikwenza oku phakathi kobude besampulu ezintlanu kwaye emva koko ilinganise imigama elinganisiweyo.
Zeziphi izinto ezichaphazela umphezulu wokugqiba?
Izinto ezininzi zichaphazela ukugqitywa komphezulu. Eyona nto inkulu kwezi zinto yinkqubo yokuvelisa. Iinkqubo zokutshiza ezifana nokujika, ukugaya, kunye nokugaya kuya kuxhomekeka kwizinto ezininzi. Ke ngoko, izinto ezichaphazela ukugqitywa komphezulu zibandakanya

Inkqubo yeMibhobho echanekileyo
Ukusetyenzwa kunye nokwenza iteknoloji yemibhobho echanekileyo yensimbi engenasici ephezulu yokusebenza yahlukile kwimibhobho yemveli engenamthungo. Izikhala zemibhobho yemveli ezingenanto ziveliswa ngokubanzi ngokugqobhoza okushushu okuqengqelekayo okuqengqeleka-mbini, kwaye inkqubo yokwenziwa kwemibhobho ngokuqhelekileyo ithatha inkqubo yokwenziwa komzobo. Iityhubhu ezichanekileyo zensimbi ezingenasici zisetyenziswa ngokubanzi kwizixhobo ezichanekileyo okanye izixhobo zonyango. Amaxabiso aphakamileyo kuphela, kodwa aqhele ukusetyenziswa kwizixhobo eziphambili kunye nezixhobo. Ngoko ke, iimfuno zezinto eziphathekayo, ukuchaneka kunye nokugqitywa komphezulu weetyhubhu zensimbi ezingenasici ziphezulu kakhulu.
Iityhubhu ezingenanto zezixhobo eziphezulu zokusebenza ezinzima-ukwenziwa ngokubanzi ziveliswa ngokutshisa okutshisayo, kwaye ukubunjwa kweetyhubhu kuqhutyelwa ngokubanzi ngokuqengqeleka okubandayo. Ezi nkqubo zibonakaliswe ngokuchaneka okuphezulu, i-deformation enkulu yeplastiki, kunye nezakhiwo ezintle zesakhiwo sombhobho, ngoko zisetyenziswa.
Ngokuqhelekileyo imibhobho yentsimbi engatyiwa ngokuqhelekileyo yintsimbi engama-301, intsimbi engama-304, intsimbi engama-316, intsimbi engama-316L, intsimbi engama-310S. Ngokuqhelekileyo, ngaphezu kwezinto ze-NI8 ziveliswa, oko kukuthi, izinto ezingaphezulu kwe-304, kunye neetyhubhu ezichanekileyo zensimbi ezingenasici kunye nezinto eziphantsi aziveliswanga.
Kuyinto yesiko ukubiza i-201 kunye ne-202 yensimbi engenasici, kuba imagnetic kwaye inomtsalane kwimagnethi. I-301 nayo ayiyo-magnetic, kodwa imagnetic emva kokusebenza okubandayo kwaye inomtsalane kwimagnethi. I-304, i-316 ayinamagnetic, ayinamtsalane kwimagnethi, kwaye ayinamathele kwimagnethi. Isizathu esona sizathu sokuba ingaba imagnethi okanye ayikho into yokuba izinto zensimbi ezingenasici ziqukethe i-chromium, i-nickel kunye nezinye izinto kwimilinganiselo eyahlukeneyo kunye nezakhiwo ze-metallographic. Ukudibanisa ezi mpawu zingentla, ikwayindlela enokwenzeka yokusebenzisa iimagnethi ukugweba umgangatho wensimbi engenasici, kodwa le ndlela ayiyonzululwazi, kuba kwinkqubo yokuvelisa intsimbi engenasici, kukho umzobo obandayo, umzobo oshushu, kwaye ngcono emva- unyango, ngoko ke imagnethi ingaphantsi okanye ayikho. Ukuba ayilungile, i-magnetism iya kuba nkulu, engakwazi ukubonisa ukucoceka kwensimbi engenasici. Abasebenzisi banokugweba ngokupakishwa kunye nokubonakala kweetyhubhu zentsimbi echanekileyo: uburhabaxa, ubukhulu obufanayo, nokuba kukho amabala kumphezulu.
Iinkqubo ezilandelayo zokuqengqeleka kunye nokuzoba zokwenziwa kombhobho nazo zibaluleke kakhulu. Ngokomzekelo, ukukhutshwa kwe-lubricant kunye ne-oxides yomhlaba kwi-extrusion ayifanelekanga, eya kuchaphazela kakhulu ukuchaneka kunye nomgangatho ophezulu wemibhobho echanekileyo yensimbi engenasici.
