Ekwakhiweni kwezingxenye zepulasitiki, ubukhulu bodonga bengxenye yipharamitha yokuqala okufanele icatshangelwe, ubukhulu bodonga bengxenye bunquma izakhiwo zemishini zengxenye, ukubukeka kwengxenye, amandla omjovo wengxenye kanye nezindleko. kwengxenye.Kungashiwo ukuthi ukukhethwa nokuklama kobukhulu bodonga bengxenye kunquma impumelelo noma ukwehluleka kwengxenye yokuklama.
Ukujiya kwengxenye yodonga kufanele kube okulingene
Ngenxa yezici zezinto zepulasitiki kanye nenqubo yomjovo,ubukhulu bodonga bezingxenye zepulasitiki kumele bube sebangeni elifanele, bungabi mncane kakhulu, futhi bungabi bukhulu kakhulu.
Uma ubukhulu bodonga buncane kakhulu, izingxenye ziyajova lapho ukugeleza kokumelana, ukuncibilika kwepulasitiki kunzima ukugcwalisa i-cavity yonke, kufanele kube imishini yomjovo wokusebenza okuphezulu ukuze uthole isivinini sokugcwalisa esiphezulu nokucindezela komjovo.
Uma ubukhulu bodonga bukhulu kakhulu, izingxenye zokupholisa isikhathi ziyanda (ngokwezibalo, ukuqina kwezindonga zezingxenye kukhuphuke izikhathi ezingu-1, isikhathi sokupholisa sikhuphuke izikhathi ezingu-4), umjikelezo wokubumba uyanda, izingxenye zokukhiqiza ziphansi;ngesikhathi esifanayo, ukujiya odongeni obukhulu kakhulu kulula ukubangela ukuthi izingxenye zikhiqize ukuncipha, i-porosity, i-warpage nezinye izinkinga zekhwalithi.
Izinto zepulasitiki ezihlukene zinezidingo ezihlukene zokuqina kodonga olufanele lwezingxenye zepulasitiki, futhi ngisho nabakhiqizi bepulasitiki abahlukene bezinto ezifanayo zepulasitiki bangase babe nezidingo ezihlukile ezifanele zokujiya udonga.Izingxenye zempahla yepulasitiki esetshenziswa kaningi zobubanzi obufanele bodonga buboniswa kuThebula 1-1.Lapho ubukhulu bodonga bezingxenye zepulasitiki buseduze nemikhawulo engaphezulu nephansi yenani eliwugqinsi olufanele, unjiniyela womklamo womkhiqizo kufanele afune iseluleko kumkhiqizi wepulasitiki.
Ithebula 1-1 Ukukhetha ukujiya kwezindonga zezingxenye zepulasitiki
(iyunithi:mm)
Izici ezibalulekile ezinquma ukushuba kodonga lwengxenye yepulasitikis:
1) Ukuthi amandla esakhiwo sengxenye anele.Ngokuvamile, ukushuba kodonga, kuba ngcono amandla engxenye.Kodwa ubukhulu bodonga lwezingxenye budlula ububanzi obuthile, ngenxa yokuncipha kanye ne-porosity nezinye izinkinga zekhwalithi, ukwandisa ukushuba kodonga lwezingxenye kuzonciphisa amandla ezingxenye.
I-2) Ingabe ingxenye ingamelana namandla okukhipha lapho ibumba.Uma ingxenye incane kakhulu, izokhubazeka kalula nge-ejection.
I-3) Ingakwazi ukumelana namandla okuqinisa ngesikhathi somhlangano.
I-4) Uma kukhona ukufakwa kwensimbi, amandla azungeze ukufakwa anele.Ukufakwa kwensimbi okujwayelekile kanye nokuncipha kwempahla yepulasitiki ezungezile akufani, kulula ukukhiqiza ukugxila kokucindezeleka, amandla aphansi.
5) Ikhono lezingxenye ukusabalalisa ngokulinganayo amandla omthelela ezingaphansi kwawo.
6) Ukuthi amandla embobo anele, amandla embobo ancishiswa kalula ngenxa yethonya lezimpawu zokuhlanganisa
7) Esakhiweni sokuhlangabezana nezidingo ezingenhla, futhi ukubumba umjovo ngeke kukhiqize izinkinga zekhwalithi, ukushuba kodonga lwezingxenye zepulasitiki kufanele kube kuncane ngangokunokwenzeka, ngoba ingxenye enkulu yodonga ngeke ikhulise izindleko zempahla nesisindo ingxenye, kodwa futhi andise umjikelezo wokubumba ingxenye, ngaleyo ndlela andise izindleko zokukhiqiza.Umfanekiso 1-3 ubonisa ubudlelwano phakathi kokuqina kodonga nesikhathi sokupholisa sengxenye yepulasitiki ye-ABS.
Ukuze kuqinisekiswe futhi kuthuthukiswe ingxenye yamandla, onjiniyela bokuklama umkhiqizo bavame ukukhetha ukujiya kwengxenye yodonga.
Eqinisweni, akuyona indlela engcono kakhulu yokuqinisekisa nokuthuthukisa ingxenye yamandla ngokukhetha ukujiya kodonga lwengxenye.Amandla engxenye angathuthukiswa ngokungeza ukuqiniswa, ukuklama amaphrofayili engxenye egobile noma e-wavy, njll. Lokhu akunciphisi nje kuphela ukungcola okubalulekile kwengxenye, kodwa futhi kufinyeza isikhathi somjikelezo wokubumba umjovo wengxenye.
Ubukhulu bodonga obufanayo bezingxenye
Ukusatshalaliswa kokuqina kodonga okuhle kakhulu kwezingxenye kunoma iyiphi ingxenye yezingxenye zokushuba okufanayo.Ukushuba okungalingani kwengxenye yodonga kungabangela ukupholisa okungalingani nokuncipha kwengxenye, okuholela ekuncipheni kwendawo, i-porosity yangaphakathi, i-warpage kanye nokuguqulwa kwengxenye, ukunemba kwe-dimensional kunzima ukuqinisekisa amaphutha.
Izibonelo zezingxenye zepulasitiki ezivamile ezinokwakheka kodonga lokujiya okufanayo ziboniswa kuMfanekiso 1-4.
Uma ingxenye umfaniswano odongeni ukushuba akunakwenzeka ukuthola, khona-ke okungenani kudingeka siqinisekise ukuthi ingxenye odongeni ukushuba futhi odongeni mncane at a inguquko abushelelezi, ukugwema izinguquko ezibukhali odongeni ukushuba ingxenye.Izinguquko ezisheshayo ekugqilazweni kodonga lwezingxenye zithinta ukugeleza kwepulasitiki yokuncibilika, kulula ukukhiqiza izimpawu zokucindezeleka ngemuva kwepulasitiki, ezithinta ukubonakala komkhiqizo;ngesikhathi esifanayo kulula ukuholela ekugxilweni kokucindezeleka, ukunciphisa amandla ezingxenye zepulasitiki, okwenza kube nzima ukuthi izingxenye zimelane nomthwalo noma umthelela wangaphandle.
Izingxenye ezine zogqinsi lwezindonga zomklamo ongalingani wodonga oluwugqinsi njengoba kukhonjisiwe kuMfanekiso 1-5.
Umklamo omubi kakhulu wodonga ukhonjiswa ku-a), lapho kukhona ushintsho olubukhali ekugqineni kodonga lwengxenye;
Ukwakheka kodonga olungcono kuboniswe kuMfanekiso b) no-c ), ukushuba kodonga ekuguqukeni komfaniswano wodonga oluncane, ngokuvamile, ubude bendawo yoguquko buphindwe kathathu ubukhulu;
Umklamo omuhle kakhulu wodonga uboniswa ku-d), hhayi kuphela ukuqina kwengxenye yodonga olubushelelezi, kodwa futhi engxenyeni yodonga oluyingxenye usebenzisa umklamo ongenalutho, hhayi kuphela ukuqinisekisa ukuthi ingxenye ayinciphi, kodwa futhi nokuqinisekisa amandla izingxenye.
Eminye imibuzo mayelana nezingxenye zepulasitiki ukuqina kodonga, sicela ukhululeke ukuxhumana nathi kuadmin@chinaruicheng.com.
