Angazi ngendlela obona ngayo ipayipi lensimbi engenamthungo? Amashubhu ensimbi angenamthungo angamashubhu ensimbi ayindilinga, ayizikwele futhi anonxande angenawo amalunga angaphandle. Ishubhu lensimbi engenamthungo lakhiwe ngensimbi yensimbi noma ishubhu eliqinile ngokubhoboza libe yishubhu le-capillary. ke yenziwa ngokuginqika okushisayo, ukugoqa okubandayo noma umdwebo obandayo. Amashubhu ensimbi angenamthungo anezingxenye ezingenalutho futhi avame ukusetshenziswa njengemigudu yokuthutha uketshezi. adinga ukugoba okufanayo namandla okugoqa futhi alula kunensimbi eqinile njengensimbi eyindilinga. ziyinsimbi eyongayo futhi zisetshenziswa kabanzi ekwakhiweni kwezakhiwo, izingxenye kanye nezingxenye eziwumshini, njengezikafula zensimbi ezisetshenziswa ekumba uwoyela.
Enqubweni yepayipi yensimbi engenamthungo, kunezinyathelo eziningi zokuthola amapayipi anekhwalithi enjalo eyinhloko. Isakhiwo se-metallographic esanelisayo sitholakala ngokuqeda ukuqina komsebenzi wamashubhu ensimbi angenamthungo. Imishini yenqubo iyisithando somlilo esikhanyayo, esisetshenziselwa ikakhulukazi. Insimbi ye-chrome eqediwe iphathwa ukushisa endaweni evikela kakhulu. Uma ukusebenza komshini wepayipi lensimbi engenamthungo kuhlukile, ukwakheka kwe-metallographic ngemva kokufakwa okukhanyayo kwe-anneal kuyehluka ngokungeziwe, ngakho-ke inqubo yokwelapha ukushisa okugqamile izohluka.
Ngemuva kokusebenza okubandayo, ingcindezi eyinsalela yezinto zamapayipi ensimbi engenamthungo ihlala, ngakho-ke ukucindezeleka okuyinsalela akulungile ngendlela emangalisayo ekuqhekekeni kokugqwala kwepayipi. Noma yiliphi izinga lokusebenza okubandayo liholela ekwandeni okukhulu kokumelana nokuqhekeka kokugqwala kwengcindezi. Izinga lokusebenza okubandayo liphinde libe nomthelela omubi emazingeni okushisa ashisayo e-austenitic stainless-steel. Ngokuvamile, izinga lokushisa elingaphezulu lokusebenza noma ngaphezulu kwezidingo zempilo yokuphuka, kwehlisa izinga lokushisa okubandayo.
Njengoba kungase kubonakale esingenisweni esingenhla, inqubo yokwelapha imfudumalo yepayipi lensimbi engenamthungo iwuhlobo olunzima. ukuze uthole ukwakheka kwe-metallographic okufanelekile, ukulungiswa kwengxenye yendawo yokupholisa yesithando somlilo esikhanyayo kufanele kube kukhulu. Ngakho-ke, isithando somlilo esithuthukisiwe esikhanyayo ngokuvamile sithatha ukupholisa kwe-convection okuqinile esigabeni saso sokupholisa, futhi sinezigaba ezintathu zokupholisa, ezingase zilungise ivolumu yomoya ngokuhlukana. ihlukaniswe yaba izingxenye ezintathu ngobubanzi bomucu.
