Iivalvuzisetyenziswa njengeseti epheleleyo yezixhobo zokwahlula umoya kwiinkqubo zeekhemikhali, kwaye ininzi yeendawo zokutywina zenziwe ngentsimbi engenasici.Kwinkqubo yokugaya, ngenxa yokukhethwa okungafanelekanga kwezinto zokugaya kunye neendlela ezingalunganga zokugaya, kungekhona nje kuphela ukuveliswa kokuveliswa kwe-valve kuyancipha, kodwa nomgangatho wemveliso uchaphazelekayo kakhulu.Ngokweempawu zezinto zensimbi ezingenasici, sikhethe ukuqina okuqinileyo kwabasebenzi kunye nokuxhatshazwa kokugqoka, kwaye umgangatho wemveliso usachaphazeleka emva kokuba iinqununu eziqhekezayo ziphulwe ekuqhutyweni.Kwiminyaka yakutshanje, siye safunda izinto ezixubileyo ezinokwakheka kwezinto ezinobunzima obunokugcina ubukhali, njenge-corundum emhlophe kunye ne-chromium oxide, ukukhethwa kwezixhobo ezixubileyo kunye ne-abrasive method, njl njl. kunye no-W5, njl.njl. Ezine zifanelekile.Ngokusebenzisa uvavanyo, luye lwakhuthazwa kwaye lusetyenziswa kwimveliso yangempela, engaphuculi kuphela umgangatho wokutywina, kodwa iphucula ukusebenza kakuhle kwemveliso kwaye ifumana iziphumo ezilungileyo kakhulu.
Ukuze i-valve yokugaya i-workpiece, okokuqala, isixhobo sokugaya sifakwe kwisihlabathi, kwaye emva koko ukugaya kuphunyezwa nge-abrasive ehlanganiswe nomxube weengqolowa eziqhekezayo kunye ne-fluid yokusila.Amandla okusila abhekisa kumandla asebenza kwindawo yokusila yeyunithi.Ngamandla asetyenziswe kwisixhobo sokugaya kunye nokusebenza phezu komhlaba ukuba kuqhutywe ngamaqhekeza abrasive.Ukuba uxinzelelo luncinci kakhulu, umphumo wokugaya uya kuba mncinci, kwaye uxinzelelo luya kwanda.Umphumo wokugaya uphuculwe, kwaye ukugaya kuphuculwe.Nangona kunjalo, xa uxinzelelo lukhula kwixabiso elithile, ukugcwala kwenzeka, kwaye ukugaya ngokuqhelekileyo kufikelela kwixabiso elikhulu.Emva koko, ukuba uxinzelelo kwindawo nganye yeyunithi iyaqhubeka nokunyuka, ukusebenza kakuhle kuya kuncipha endaweni yoko.
Oku kungenxa yokuba i-valve abrasive particles inomda othile wokumelana noxinzelelo.Xa eli xabiso lomda ligqithiswa, ziya kutyunyuzwa, zenze iincinci ze-abrasive zibe zihle kwaye zinciphise ukukwazi ukuzigaya.Ngoko ke, uxinzelelo lweyunithi kufuneka luzimisele ngokwamandla kunye neempawu ezityumzayo ze-abrasive.Emva kovavanyo, ezi parameters zilandelayo kufuneka zikhethwe ngokubanzi: ① Kwisila esirhabaxa, kwi-white corundum abrasive, khetha 0.2 ukuya ku-0.5 MPa.③ Ngexesha lokusila kakuhle, khetha i-0.03～0.12MPa ye-abrasive ye-jade emhlophe.
Isantya sokugaya sibhekisela kwisantya sokuhamba esihambelanayo sesixhobo sokugaya phezu kwendawo yokusebenza.Isantya sokugaya yinkqubo ebalulekileyo yeparameter yokulawula ubungakanani bokususwa kwentsalela, isantya sokususa kunye nomgangatho womgangatho owenziweyo.Umzobo wesi-2 lijiko lobudlelwane obuqhelekileyo phakathi kokususwa kobungakanani bomsebenzi, uburhabaxa bomphezulu owenziwe ngoomatshini kunye nesantya sokusila.
Umsebenzi wesixhobo sokugaya kunye nesixhobo saso sokugaya kukulungisa okwethutyana i-abrasive kwaye ufumane intshukumo ethile yokugaya, kwaye idlulisele imo yejometri yayo kwi-workpiece ngendlela ethile.Ngoko ke, izinto eziphathekayo zokugaya kufuneka zibe nokufakela ngokufanelekileyo iinkozo ezinqabileyo kunye nokugcinwa kwexesha elide lokuchaneka kwayo kwejometri.Intsimbi engwevu i-HT200 yinto efanelekileyo yokwenza ukucola.Isakhiwo sayo siqulethe i-cementite enzima kwaye inxiba-resistant, i-ferrite enobunzima obuhle kunye neplastiki, kwaye iqulethe i-graphite, enefuthe lokuthambisa kwaye kulula ukuyilo kunye nokusebenza..
Xa ixesha lokugaya elifunekayo ukufumana umgangatho ochaziweyo womhlaba mkhulu kunexesha elifunekayo ukususa umda.Isantya sokugaya kufuneka sincitshiswe ngokufanelekileyo.Emva kovavanyo, la maxabiso alandelayo esantya afaneleke ngakumbi: ①Ngexesha lokusila ngokurhabaxa, isantya sezixhobo zokusila okanye izixhobo zokusebenza kufuneka zicolwe yi-20-50m/min.②Xa ivalve ikwimeko entle yokusila, isantya sesixhobo sokusila okanye i-workpiece ekufuneka icolwe yi-6 ~ 12m/min.Ukukhethwa kwexabiso loburhabaxa bomphezulu Uburhabaxa bomphezulu sesinye sezalathi ezingundoqo zomgangatho womphezulu.Inempembelelo enkulu kumsebenzi womphezulu.Inefuthe elithe ngqo kwi-surface abrasion, ukuqina koqhagamshelwano kunye nokusebenza kokutywinwa, kwaye ngexesha elifanayo lichaphazela ukusebenza kunye nobomi bemveliso.Xa usebenzisa iindlela ezahlukeneyo zokusila kunye nobukhulu bamasuntswana, uburhabaxa bomphezulu obuphunyeziweyo bukwahlukile.
