Amapuleti ongaphezulu kwe-granite angamathuluzi okunemba asetshenziswa kabanzi ekulinganisweni, ekuhlolweni, nasekusetshenzisweni kwemishini. Enziwe nge-granite yemvelo esezingeni eliphezulu, eyaziswa ngokuqina kwayo, ukuqina kwayo, kanye nokuba yisicaba. Kodwa-ke anembile kangakanani lawa mapuleti?
Ukuzinza Kwemvelo
I-granite yakhiwa eminyakeni eyizigidi ngaphansi kwengcindezi nokushisa okukhulu, okuholela esakhiweni esiminyene nesinobukhulu obuncane. Lokhu kuzinza kwemvelo kwenza i-granite ibe yinto efanelekile yamapuleti angaphezulu, njengoba imelana nokuguquguquka kwezinga lokushisa, umswakama, kanye nokucindezeleka komshini. Eqinisweni, i-granite ine-coefficient ephansi yokwanda kokushisa, okusho ukuthi iyanda futhi incipha kancane kakhulu ngokushintshashintsha kwezinga lokushisa. Lesi sici siqinisekisa ukuthi ubuso bepuleti buhlala buyisicaba futhi buqinile, ngisho nasezindaweni eziyinselele.
Ukukhiqiza Ngokucophelela
Ukuze kufezwe amazinga aphezulu okunemba, amapuleti obuso begranite adlula enkambisweni yokukhiqiza eqinile. Okokuqala, ibhulokhi legranite likhethwa ngokucophelela ngenxa yekhwalithi yalo kanye nokuvumelana kwalo. Bese, lisikwa libe usayizi nesimo esifunwayo. Okulandelayo kuza inqubo yokugoqa nokupholisha, lapho ubuso buhlungwa khona kancane kancane kusetshenziswa izinto ezihuquzelayo. Le nqubo ecophelelayo ingafinyelela ubulukhuni bobuso obuphansi kakhulu kanye nokubekezelelana okuphezulu kokusicaba.
Izindinganiso Zokunemba
Ukunemba kwamapuleti ongaphezulu e-granite kuvame ukucaciswa ngokubekezelela kwawo ukuba yisicaba. Ngokusho kwe-American Society of Mechanical Engineers (ASME) B89.3.7 standard, amapuleti ongaphezulu alinganiswa ngokusekelwe ekutheni ayisicaba. Izinga eliphakeme kakhulu, i-AA, linokumelana okuqinile, okwenza lifaneleke kuma-laboratory okulinganisa kanye ne-metrology enembile kakhulu. Amapuleti e-Grade A avame ukusetshenziswa ezindaweni zokuhlola, kuyilapho amapuleti e-Grade B, anokubekezelelana okukhululekile kancane, angatholakala phansi kwesitolo.
Isibonelo, ipuleti lobuso le-granite elingu-12" x 12" le-AA-grade lingase libe nokubekezelela ukuthamba okungu-±0.00005 amayintshi kulo lonke ubuso balo. Leli zinga lokunemba livumela ukulinganisa okunembe kakhulu kanye nokulinganisa amanye amathuluzi nezingxenye.
Izici Ezithinta Ukunemba
Nakuba amapuleti ongaphezulu e-granite enembile ngokwemvelo, izici eziningana zingathinta ukusebenza kwawo ngokuhamba kwesikhathi. Ukuphathwa okungalungile, njengokuwisa noma ukufaka ipuleti emandleni amakhulu, kungabangela ama-chips noma imifantu engathinta ukuthamba. Ngaphezu kwalokho, izici zemvelo ezifana nokushintsha kwezinga lokushisa okukhulu noma amazinga aphezulu omswakama nazo zingathinta ukunemba kwepuleti. Ukuhlanza nokugcinwa njalo, kanye nokugcinwa okufanele, kubalulekile ukuze kulondolozwe ukunemba kwepuleti.
Ekuphetheni, amapuleti obuso be-granite anikeza ukunemba okumangalisayo, okwenza abe ukukhetha okuthembekile kwezicelo lapho ukunemba kubalulekile khona. Ukuqina kwawo kwemvelo, kuhlanganiswe namasu okukhiqiza ngokunemba, kuwavumela ukuthi ahlinzeke ngendawo yokubhekisela ezinzile nenembile yezimboni eziningi, kusukela ezindizayo nasezimotweni kuya ekukhiqizweni kwezinto zikagesi nezokwelapha.
