Emkhakheni wokulinganisa ngokunemba, i-profilometer iyithuluzi eliyinhloko lokuthola idatha enembile kakhulu, kanti isisekelo, njengengxenye ebalulekile ye-profilometer, ikhono layo lokumelana nokuphazamiseka kwe-electromagnetic lithinta ngqo ukunemba kwemiphumela yokulinganisa. Phakathi kwezinto eziyisisekelo ezahlukahlukene, i-granite ne-cast iron kuyizinketho ezivamile. Uma kuqhathaniswa nezisekelo ze-profilometer ze-cast iron, izisekelo ze-granite profilometer zibonise izinzuzo ezibalulekile ekuqedeni ukuphazamiseka kwe-electromagnetic futhi sezibe ukukhetha okuhle kokulinganisa ngokunemba okuphezulu.
Ithonya lokuphazamiseka kwe-electromagnetic ekulinganisweni kwama-profilometer
Esimweni sezimboni sanamuhla, ukuphazamiseka kwe-electromagnetic kukhona yonke indawo. Kusukela emisebeni ye-electromagnetic ekhiqizwa imishini emikhulu esebenza eshabhu kuya ekuphazamisekeni kwesignali evela kumadivayisi kagesi azungezile, uma lezi zimpawu zokuphazamiseka zithinta i-profilometer, zizobangela ukuphambuka nokuguquguquka kwedatha yokulinganisa, futhi zize ziholele ekwahluleleni okungalungile kohlelo lokulinganisa. Ekulinganisweni kwe-contour okudinga ukunemba ezingeni le-micrometer noma ngisho ne-nanometer, ngisho nokuphazamiseka kwe-electromagnetic okubuthakathaka kungabangela imiphumela yokulinganisa ukuthi ilahlekelwe ukuthembeka, ngaleyo ndlela kuthinte ikhwalithi yomkhiqizo kanye nokusebenza kahle kokukhiqiza.
Inkinga yokuphazamiseka kwe-electromagnetic yesisekelo se-cast iron profilometer
Insimbi ephothiwe iyinto yendabuko yokukhiqiza izisekelo futhi isetshenziswa kabanzi ngenxa yezindleko zayo eziphansi kanye nenqubo yokukhiqiza evuthiwe. Kodwa-ke, insimbi ephothiwe inomoya omuhle kagesi, okwenza ibe sengozini yokungeniswa kwe-electromagnetic endaweni ye-electromagnetic. Lapho insimu ye-electromagnetic ekhishwa umthombo wokuphazamiseka kwe-electromagnetic yangaphandle isebenza esisekelweni sensimbi ephothiwe, kuzokhiqizwa ugesi obangelwa ngaphakathi kwesisekelo, kwakha ugesi we-electromagnetic eddy. Lawa ma-electromagnetic eddy currents awakhi nje kuphela amasimu e-electromagnetic yesibili, aphazamisa izimpawu zokulinganisa ze-profilometer, kodwa futhi abangela ukuthi isisekelo sishise, okuholela ekuguqukeni kokushisa futhi kuthinte kakhulu ukunemba kokulinganisa. Ngaphezu kwalokho, isakhiwo sensimbi ephothiwe sikhululekile futhi asikwazi ukuvikela ngempumelelo izimpawu ze-electromagnetic, okuvumela ukuphazamiseka kwe-electromagnetic ukungena kalula esisekelweni futhi kubangele ukuphazamiseka kumasekethe okulinganisa angaphakathi.
Inzuzo yokususa ukuphazamiseka kwe-electromagnetic yesisekelo se-granite profilometer
Izakhiwo zemvelo zokuvikela umswakama
I-Granite uhlobo lwetshe lemvelo. Amakristalu ayo amaminerali angaphakathi aqiniswe kakhulu futhi isakhiwo siminyene. Iyisivikelo esihle. Ngokungafani nensimbi ephonswe, i-granite cishe ayihambisani nogesi, okusho ukuthi ngeke ikhiqize imisinga ye-electromagnetic eddy endaweni ye-electromagnetic, okugwema izinkinga zokuphazamiseka okubangelwa ukungeniswa kwe-electromagnetic. Lapho insimu ye-electromagnetic yangaphandle isebenza esisekelweni se-granite, ngenxa yezakhiwo zayo zokuvimbela, insimu ye-electromagnetic ayikwazi ukwakha iluphu ngaphakathi kwesisekelo, ngaleyo ndlela inciphise kakhulu ukuphazamiseka ohlelweni lokulinganisa i-profilometer.
Ukusebenza kahle kakhulu kokuvikela
Isakhiwo esiminyene segranite siyinika amandla athile okuvikela i-electromagnetic. Nakuba igranite ingenakukwazi ukuvimba ngokuphelele izimpawu ze-electromagnetic njengezinto zokuvikela insimbi, ingahlakaza futhi imunce izimpawu ze-electromagnetic ngesakhiwo sayo, ngaleyo ndlela inciphise amandla okuphazamiseka kwe-electromagnetic. Ngaphezu kwalokho, ekusetshenzisweni okungokoqobo, isisekelo se-granite profilometer singahlanganiswa nemiklamo yokuvikela i-electromagnetic ezinikele, njengokwengeza ungqimba lokuvikela insimbi, njll., ukuze kuthuthukiswe umphumela wayo wokuvikela i-electromagnetic futhi kuhlinzekwe indawo yokusebenza ezinzile yesistimu yokulinganisa.
Izakhiwo zomzimba ezizinzile
Ngaphezu kokuqeda ngqo ukuphazamiseka kwe-electromagnetic, izakhiwo zomzimba ezizinzile ze-granite nazo zinegalelo ngokungaqondile ekuthuthukiseni ikhono lokulwa nokuphazamiseka kwe-profilometer. I-Granite ine-coefficient ephansi kakhulu yokwanda kokushisa futhi ayidluli ekuguqulweni kobukhulu lapho izinga lokushisa lishintsha. Lokhu kusho ukuthi ezimweni lapho ukuphazamiseka kwe-electromagnetic kungabangela izinguquko zokushisa zendawo, isisekelo se-granite sisengagcina isimo nosayizi ozinzile, siqinisekisa ukunemba kwereferensi yokulinganisa futhi sigweme amaphutha engeziwe okulinganisa alethwe ngenxa yokuguqulwa kwesisekelo.
Namuhla, ekufuneni ukulinganisa okunembile kakhulu, izisekelo ze-granite profilometer, ezinezakhiwo zazo zemvelo zokuvikela, ukusebenza kahle kakhulu kokuvikela kanye nezakhiwo zomzimba ezizinzile, zingcono kakhulu kunezisekelo ze-cast iron profilometer ekuqedeni ukuphazamiseka kwe-electromagnetic. Ukukhetha i-profilometer enesisekelo se-granite kungagcina ukulinganisa okuzinzile nokunembile ezindaweni eziyinkimbinkimbi ze-electromagnetic, kunikeze iziqinisekiso zokulinganisa ezinokwethenjelwa zezimboni ezinezidingo zokunemba okuphezulu kakhulu njengokukhiqiza nge-elekthronikhi, ukucubungula ngomshini okunembile, kanye nezindiza, nokusiza amabhizinisi ukuthuthukisa ikhwalithi yomkhiqizo kanye nokuncintisana.
