Ngaba uyayazi indlela yokukhetha iinxalenye kunye nemathiriyeli?

Ukukhetha izinto eziza kusetyenziswa kwizinto ezahlukeneyo zemathiriyeli ngumsebenzi othintelwe yimiba emininzi.Ngoko ke, indlela yokukhetha izinto eziphathekayo yinxalenye ebalulekileyo yecandelo loyilo. iimfuno zokusetyenziswa kwamalungu kunyeube neteknoloji elungileyo kunye noqoqosho.

Sebenzisa okufunekayo

Iimfuno zokusetyenziswa kwamalungu oomatshini zezi zilandelayo:
1) Iimeko zokusebenza kunye neemeko zomthwalo wamacandelo kunye neemfuno zokuphepha iifom zokungaphumeleli ezihambelanayo.
Imeko yokusebenza ibhekiselele kwiimpawu zokusingqongileyo, ubushushu bokusebenza kunye nomgangatho wokungqubuzana kunye nokunxiba kwamacandelo.Iinxalenye ezisebenza kwindawo eshushu kunye nefumileyo okanye kwimithombo yeendaba ezonakalisayo, izinto zazo kufuneka zibe nomhlwa olungileyo kunye nokumelana nokubola, kulo mzekelo, unokuqwalasela kuqala ukusetyenziswa. I-alloy yensimbi engenasici, i-alloy yobhedu. Impembelelo yokushisa okusebenzayo ekukhethweni kwezinto eziphathekayo ineenkalo ezimbini: kwelinye icala, kuyimfuneko ukuqwalasela i-coefficient yokwandisa i-linear yezixhobo zamacandelo amabini asebenzisanayo akufanele ahluke kakhulu. kakhulu, ukuze kungavelisi uxinzelelo olugqithisileyo lwe-thermal okanye ukulungelelana okukhululekileyo xa ubushushu buguquka;Kwelinye icala, utshintsho lweempawu zomatshini wezinto ezinobushushu kufuneka ziqwalaselwe. Umyalelo wokomeleza ukuxhathisa ukunxiba, kufuneka ukhethe ngokufanelekileyo kunyango lomphezulu wentsimbi eqinile, intsimbi ye-carburized, intsimbi ye-nitride kunye nezinye iintlobo okanye ukhethe ukucutha ukungqubana kunye nokumelana nokunxiba kwezinto ezilungileyo.
Imeko yomthwalo ibhekiselele kubukhulu kunye nendalo yomthwalo kunye noxinzelelo kwicala.Izinto eziphathekayo zifanelekile kuphela kwiindawo zokuvelisa ezisebenza phantsi kwemithwalo engatshintshiyo; Kwimeko yempembelelo, izinto zeplastiki kufuneka zisetyenziswe njengeyona nto iphambili; Kuba Umphezulu wamacandelo amakhulu oxinzelelo loqhagamshelwano, kufuneka ukhethe unyango olungaphezulu lwezixhobo, ezifana nentsimbi yomphezulu; ;Kuba ubungakanani buxhomekeke kumandla kunye nobungakanani kunye nomgangatho wamalungu anyiniweyo, kufuneka kukhethwe imathiriyeli yokomelela okuphezulu;Kumalungu anomlinganiselo oxhomekeke ekuqina, imathiriyeli enemoduli eelastiki enkulu kufuneka ikhethwe.
Ngokuqhelekileyo, iipropati zezinto zetsimbi zingaphuculwa kwaye ziphuculwe ngonyango lokushisa.Ngoko ke, kuyimfuneko ukusebenzisa ngokupheleleyo iindlela zonyango lobushushu ukuphuhlisa amandla ezinto eziphathekayo.Kwintsimbi esetyenziswa ngokuqhelekileyo imodulated, i-blank eneempawu ezahlukeneyo zoomatshini inokufumaneka ngenxa yobushushu obuhlukeneyo. ubushushu, ubunzima obuphantsi kunye nokuqina kwezinto eziphathekayo, kwaye ngcono iplastiki.Ngoko ke, xa ukhetha izinto ezahlukeneyo, ukucaciswa konyango lokushisa kufuneka kuchazwe ngexesha elifanayo, kwaye kuboniswe kumzobo.

2) Ukulinganiselwa kubukhulu kunye nomgangatho wamalungu.
Ubungakanani bezahlulo kunye nomgangatho wobungakanani kunye nezinto ezahlukeneyo kunye nendlela yokuvelisa engenanto.Ukuveliswa kokuphosa okungenanto ngokubanzi akunakuthintelwa ngobungakanani kunye nobukhulu obukhulu;kwimveliso yokubumba engenanto, kuyimfuneko ukunikela ingqalelo kumthamo wemveliso yokubumba. oomatshini kunye nezixhobo.Ukongezelela, ubungakanani bamacandelo kunye nomgangatho wobungakanani kunye nomlinganiselo wezinto eziphathekayo, kufuneka kube ngokusemandleni ukukhetha umlinganiselo oqinileyo wobunzima bezinto ezinkulu, ukwenzela ukunciphisa ubungakanani kunye nomgangatho wamacandelo.

3) Ukubaluleka kweengxenye kumatshini wonke kunye namacandelo.
4) Ezinye iimfuno ezikhethekileyo (ezifana ne-insulation, diamagnetic, njl.).

 

IiMfuno zeTekhnoloji

Ukuze kwenziwe iinxalenye zibe lula ukuvelisa, ukuntsokotha kwesakhiwo samalungu, ubungakanani kunye nodidi olungenanto kufuneka luqwalaselwe xa kukhethwa izixhobo. Kwiindawo ezinemilo entsonkothileyo kunye nobukhulu obukhulu, ukuba ukuphosa okungenanto kuqwalaselwa, ukusebenza kakuhle kokuphosa kufuneka kukhethwe; I-welding blank ithathwa, i-carbon iron ephantsi kunye nokusebenza kakuhle kwe-welding kufuneka ikhethwe.Ukwenzela imilo elula, ubungakanani obuncinci, ibhetshi enkulu yamacandelo, alungele ukunyathela kunye nokufa, kufuneka ukhethe izinto ezilungileyo zeplastiki. izinto eziphathekayo kufuneka zibe nokusebenza kakuhle kwonyango lokushisa.Ukongezelela, ukusebenza kwezinto ngokwazo kunye nokusebenza emva kokunyanga kobushushu kufuneka kuqwalaselwe.

Imfuneko yoQoqosho

1) Ixabiso elihambelanayo lezinto eziphathekayo ngokwazo

Ngaphantsi kwesiseko sokuhlangabezana neemfuno zokusetyenziswa, izinto eziphantsi kwexabiso eliphantsi kufuneka zikhethwe kangangoko kunokwenzeka.Oku kubaluleke kakhulu kwiindawo ezenziwe ngobuninzi.
2) Ukulungiswa kweendleko zemathiriyeli
Xa umgangatho wecandelo ungekho mkhulu kwaye ubungakanani bokulungiswa bukhulu, iindleko zokucubungula ziya kuphendula inxalenye enkulu yeendleko ezipheleleyo zecandelo.Nangona intsimbi etyhidiweyo ingabizi kunepleyiti yentsimbi, kubiza kakhulu ukuphosa i-weld cast. intsimbi kunepleyiti yentsimbi kwiindawo ezithile zebhokisi enye okanye encinci ngenxa yokuba le yokugqibela igcina iindleko zokwenziwa komngundo.
3) Gcina izixhobo
Ukugcina izixhobo, unyango lobushushu okanye ukomelezwa komphezulu (ukudubula, ukuqengqeleka, njl.njl.) kunokusetyenziselwa ukudlala ngokupheleleyo kunye nokusebenzisa iipropathi ezinokubakho zezixhobo zemathiriyeli; Ukwaleka komphezulu (i-chrome plating, i-copper plating, i-blackening, eluhlaza okwesibhakabhaka, njl.njl) ingasetyenziselwa ukunciphisa iqondo lokubola kunye nokunxiba, ukwandisa ubomi benkonzo yamalungu.
4) Izinga lokusetyenziswa kwezinto
Ukuze kuphuculwe izinga lokusetyenziswa kwezixhobo, akukho kusika okanye ukusika kuncinci kunokusetyenziswa, njengokubumba ukufa, ukuphosa utyalo-mali, ukunyathela, njl. ukusika.
5) Gcina izinto ezixabisekileyo
Ngokusetyenziswa kwesakhiwo esidityanisiweyo, kunokonga ixabiso lezinto eziphezulu, ezifana nesangqa esidityanisiweyo segiya yeentshulube ngokucutha ukukhuhlana okuhle kodwa ubhedu olubiziyo lwenkcenkce, kwaye umbindi wevili unexabiso eliphantsi.
6) Gcina izinto ezinqabileyo
Kule meko, iintsimbi ze-manganese-boron alloy ezinemithombo eninzi e-China zingasetyenziselwa ukutshintsha i-chromium-nickel alloy steels kunye nezixhobo ezincinci, kunye ne-aluminium bronze ingasetyenziselwa ukutshintsha i-tin bronze.
7) Ukunikezelwa kwezinto
Ekukhetheni imathiriyeli, kufuneka ukhethe izinto ezifumaneka ekuhlaleni kwaye kulula ukuzinikezela, ukuze kuncitshiswe iindleko zokuthenga, ukuthutha, ukugcinwa; ukusuka kwiintlobo zezinto ezenziwe lula zombono wokubonelela kunye nokugcinwa, kwimveliso encinci yebhetshi yamacandelo, kufuneka. ukunciphisa kangangoko kumatshini ofanayo ukusetyenziswa iintlobo zezinto kunye neenkcukacha, ukwenzela ukuba kube lula unikezelo kunye nolawulo, kwaye kwinkqubo machining kunye nobushushu unyango lula kakhulu ukuba inkosi eyona ndlela yokusebenza isengqiqweni, ngaloo ndlela ukuphucula umgangatho yokuvelisa, ukunciphisa inkunkuma, ukuphucula imveliso yabasebenzi.
