Uyazi ukuthi ungakhetha kanjani izingxenye nezinto zokwakha?

Ukukhetha izinto ezizosetshenziswa ezintweni ezihlukahlukene kuwumsebenzi ovinjelwe izici eziningi.Ngakho-ke, indlela yokukhetha impahla yezingxenye yingxenye ebalulekile yezingxenye zokuklama.Isimiso sokukhetha izingxenye zemishini yilezi: izinto ezidingekayo kufanele zihlangane. izidingo zokusetshenziswa kwezingxenye kanyebabe nobuchwepheshe obuhle nomnotho.

Sebenzisa Imfuneko

Izidingo zokusebenzisa izingxenye zemishini zimi kanje:
1) Izimo zokusebenza kanye nezimo zomthwalo wezingxenye kanye nezidingo zokugwema amafomu okuhluleka ahambisanayo.
Isimo sokusebenza sibhekisela ezicini zemvelo, izinga lokushisa elisebenzayo kanye nezinga lokungqubuzana nokuguga kwezingxenye.Izingxenye ezisebenza endaweni eshisayo nenomswakama noma imidiya egqwalayo, izinto zazo kufanele zibe nokugqwala okuhle nokumelana nokugqwala, kulokhu, kungacatshangelwa kuqala ukusetshenziswa. yensimbi engagqwali, ingxubevange yethusi.Ithonya lokushisa okusebenzayo ekukhetheni impahla ngokuyinhloko linezici ezimbili: ngakolunye uhlangothi, kuyadingeka ukucabangela i-coefficient yomugqa wokwandisa wezinto zezingxenye ezimbili ezisebenzisanayo akufanele zihluke futhi. okuningi, ukuze kungakhiqizi ukucindezeleka okushisayo ngokweqile noma ukulingana okuxekethile lapho izinga lokushisa lishintsha;Ngakolunye uhlangothi, ukuguqulwa kwezakhiwo zemishini yezinto ezinokushisa kufanele kucatshangelwe. ukuze kuthuthukiswe ukumelana nokugqokwa, kufanele akhethe okulungele ukwelashwa okungaphezulu kwensimbi eqinile, insimbi ye-carburized, insimbi ye-nitride nezinye izinhlobo noma ukhethe ukunciphisa ukungqubuzana nokumelana nokugqoka kwezinto ezinhle.
Isimo somthwalo sisho ubukhulu kanye nemvelo yomthwalo kanye nengcindezi engxenyeni. Izinto zokwakha eziqinile zifaneleka kuphela izingxenye zokukhiqiza ezisebenza ngaphansi kwemithwalo engashintshi;Endabeni yomthelela, izinto zepulasitiki kufanele zisetshenziswe njengento eyinhloko; indawo engaphezulu yezingxenye ezinkulu zengcindezi yokuxhumana, kufanele ikhethe ukwelapha okungaphezulu kwezinto, njengensimbi eqinisa indawo; Ezingxenyeni ezingaphansi kwengcindezi, izinto ezimelana nokukhathala kufanele zikhethwe; Ezingxenyeni ezingaphansi komthwalo onomthelela, izinto ezinokuqina komthelela omkhulu kufanele zikhethwe. ;Ngokuba usayizi uncike emandleni kanye nosayizi kanye nekhwalithi yezingxenye kunqunyelwe, kufanele kukhethwe izinto ezisetshenziswayo ezinamandla;Ezingxenyeni ezinobukhulu obuncike ekuqineni, izinto zokwakha ezinemoduli enkulu yokunwebeka kufanele zikhethwe.
Ngokuvamile, izakhiwo zezinto zensimbi zingathuthukiswa futhi zithuthukiswe ngokwelashwa kokushisa.Ngakho-ke, kudingekile ukusebenzisa ngokugcwele izindlela zokwelapha ukushisa ukuze kuthuthukiswe amandla ezinto zokwakha.Ngensimbi esetshenziswa kakhulu eguquliwe, okungenalutho okunezinto ezihlukahlukene zemishini kungatholakala ngenxa yokushisa okuhlukahlukene okushisayo.Ukuphakama okuphezulu izinga lokushisa, ukuncipha kokuqina nokuqina kwempahla, futhi kungcono ipulasitiki.Ngakho-ke, lapho ukhetha izinto ezihlukahlukene, ukucaciswa kokwelashwa kokushisa kufanele kubekwe ngesikhathi esifanayo, futhi kuboniswe emdwebeni.

2) Imikhawulo kusayizi kanye nekhwalithi yezingxenye.
Usayizi wezingxenye kanye nekhwalithi yosayizi nezinhlobonhlobo zezinto kanye nendlela yokukhiqiza engenalutho.Ukukhiqizwa kokusakazwa kungenalutho ngokuvamile angeke kukhawulwe ngosayizi nosayizi omkhulu;Ekukhiqizweni kokubumba kungenalutho, kuyadingeka ukunaka amandla okukhiqiza wokubumba. imishini kanye nemishini.Ngaphezu kwalokho, ubukhulu bezingxenye kanye nekhwalithi yesilinganiso sobukhulu nesisindo sempahla, kufanele kube ngangokunokwenzeka ukukhetha isilinganiso esinamandla sesisindo sezinto ezinkulu, ukuze kuncishiswe ubukhulu kanye nekhwalithi yezingxenye.

3) Ukubaluleka kwezingxenye kuwo wonke umshini kanye nezingxenye.
4) Ezinye izidingo ezikhethekile (ezifana nokufakwa, i-diamagnetic, njll.).

 

Izidingo zobuchwepheshe

Ukuze wenze izingxenye zibe lula ukwakhiwa, inkimbinkimbi yesakhiwo sezingxenye, usayizi kanye nohlobo olungenalutho kufanele kucatshangelwe lapho kukhethwa izinto zokwakha. Ezingxenyeni ezinomumo oyinkimbinkimbi nosayizi omkhulu, uma ukusakaza kungenalutho kucatshangelwa, ukusebenza kahle kokulingisa kufanele kukhethwe; I-welding blank ibhekwa, insimbi ephansi ye-carbon steel esebenza kahle yokushisela kufanele ikhethwe.Ukuze kube nesimo esilula, usayizi omncane, inqwaba yezingxenye, ezifanele ukugxiviza nokufaka ukufa, kufanele ukhethe izinto ezinhle zepulasitiki.Ezingxenyeni ezidinga ukwelashwa ukushisa, i impahla kufanele ibe nokusebenza okuhle kokwelashwa kokushisa.Ngaphezu kwalokho, ukusebenza kwempahla ngokwayo kanye nokusebenza ngemva kokwelashwa kokushisa kufanele futhi kucatshangelwe.

Imfuneko Yezomnotho

1) Intengo ehlobene yento ngokwayo

Ngaphansi kwesisekelo sokuhlangabezana nezidingo zokusetshenziswa, izinto ezingabizi kakhulu kufanele zikhethwe ngangokunokwenzeka.Lokhu kubaluleke kakhulu ezingxenyeni ezikhiqizwa ngobuningi.
2) Ukucubungula izindleko zezinto
Uma izinga lengxenye lingelikhulu futhi nenani lokucubungula likhulu, izindleko zokucubungula zizolandisa ingxenye enkulu yezindleko eziphelele zengxenye.Nakuba insimbi ekhonjiwe ishibhile kunepuleti lensimbi, kubiza kakhulu ukushisela insimbi. insimbi kunepuleti lensimbi lezingxenye ezithile zebhokisi elilodwa noma elinevolumu encane ngoba lokhu konga izindleko zokukhiqiza isikhunta.
3) Gcina izinto zokwakha
Ukuze ulondoloze izinto ezisetshenziswayo, ukwelapha ukushisa noma ukuqinisa indawo (ukuchama, ukugingqika, njll.) kungasetshenziswa ukuze kudlalwa ngokugcwele futhi kusetshenziswe izinto ezingase zibe khona zemishini;Isimbozo esingaphezulu (i-chrome plating, i-copper plating, i-blackening, eluhlaza okwesibhakabhaka, njll.) futhi ingasetshenziswa ukunciphisa izinga lokugqwala nokuguga, yelule impilo yesevisi yezingxenye.
4) Izinga lokusetshenziswa kwezinto
Ukuze kuthuthukiswe izinga lokusetshenziswa kwezinto, akukho ukusika noma ukusika okuncane okungasetshenziswa, njengokubumba ifa, ukutshala imali, ukugxiviza, njll., okungagcini nje ukuthuthukisa izinga lokusetshenziswa kwezinto, kodwa futhi kunciphise amahora okusebenza ukusika.
5) Gcina izinto ezibalulekile
Ngokusebenzisa ukwakheka okuhlanganisiwe, kungasindisa intengo yezinto eziphakeme, njengendandatho ehlanganisiwe yegiya lezikelemu ezinokunciphisa ukungqubuzana okuhle kodwa ithusi elibizayo lethayela, kanti umgogodla wesondo uyinsimbi ekhonjiwe eshibhile.
6) Gcina izinto ezingavamile
Kulokhu, izinsimbi ze-manganese-boron alloy ezinezinsiza eziningi e-China zingasetshenziswa ukufaka esikhundleni sezinsimbi ze-chromium-nickel alloy ngezinsiza ezincane, futhi ithusi le-aluminium lingasetshenziswa esikhundleni sethusi le-tin.
7) Ukunikezwa kwezinto
Ekukhetheni izinto zokwakha, kufanele zikhethe izinto ezitholakala endaweni futhi ezitholakala kalula, ukuze kwehliswe izindleko zokuthenga, ezokuthutha, ukugcinwa;Kusukela ezinhlobonhlobo zezinto ezenziwe lula zombono wokuhlinzekwa nokugcinwa, ukukhiqizwa kwenqwaba yezingxenye, kufanele. ukunciphisa ngangokunokwenzeka emshinini ofanayo sebenzisa izinhlobo zezinto ezibonakalayo kanye nokucaciswa, ukuze kube lula ukunikezwa nokuphatha, futhi inqubo yomshini wokushisa nokushisa kulula kakhulu ukuqonda indlela yokusebenza enengqondo kakhulu, ngaleyo ndlela ithuthukise ikhwalithi yokukhiqiza, ukunciphisa i-scrap, ithuthukisa ukukhiqizwa kwabasebenzi.
