I-Valve Casting ethuthuka eNingbo

Ngemuva kokuthi i-valve isetshenziselwa isikhathi eside, izindawo zokubopha uphawu ze-valve disc nesihlalo se-valve zizoguga futhi ukuqina kuzoncishiswa. Ukulungisa uphawu lokubopha kungumsebenzi omkhulu futhi obalulekile. Indlela esemqoka yokulungisa iyagaya. Ebusweni obunzima bokubekwa uphawu, kungukuqala kokushona phansi ngemuva kokugaya bese ugaya.

I-valve yokugaya kufaka phakathi inqubo yokuhlanza nokuhlola, inqubo yokugaya kanye nenqubo yokuhlola.

1, ukuhlanza nokuhlola inqubo

Hlanza indawo yokubekwa uphawu epanini lamafutha, ukusetshenziswa kwama-ejenti wokuhlanza ochwepheshe, ngenkathi ugeza ingaphezulu ukuze uhlole ukulimala komhlaba wokubopha. Ukuqhekeka okucashile ngeso elinqunu kunganqunywa ngokuhlolwa kombala. Ngemuva kokuhlanza, kufanele kuhlole i-valve flap noma indawo ehleli kahle ye-valve Ukuhlolwa okubomvu okubomvu, hlola isithunzi sokuphrinta se-BATION SPROPT, ukunquma isimo esiseduze sokuvalwa komhlaba; Noma indawo yepensela ne-valve isihlalo se-seal idweba imibuthano ehlukahlukene, bese uvala ukujikeleza kwe-valve disc nokujikeleza kwesihlalo se-valve, hlola umbuthano wepensela Sula isimo, ukunquma indawo yokuvala uphawu. Uma kufanelekile, ipuleti elijwayelekile lingasetshenziswa ukuvivinya i-valve flap noma indawo yokuvalwa kweSango kanye ne-valve uphawu lokubopha, ukuthola indawo yokugaya.

2, inqubo yokugaya

Inqubo yokugaya empeleni ayikho inqubo yokusika ye-lathe, ikhanda le-valve noma isihlalo esiseduze noma ukujula umgodi ngokuvamile kungakapheli i-0.5mm, ungasebenzisa indlela yokugaya ngokulungiswa. Inqubo yokugaya ihlukaniswe yaba ukugaya kwama-coarse, ukugaya nokugaya okuhle.

Ukugaya okunolaka ukuqeda indawo yokubekwa uphawu kwe-scratch, i-induction, amaphuzu atching nezinye iziphambeko, ukuze indawo enophawu oluthile lokuthola ubushelelezi obukhulu kanye nokuqeda isilinganiso esithile sokuqeda uphawu lokugaya kwabeka isisekelo. Ukugaya kwama-coarse kusetshenziswa ama-head ekhanda noma amathuluzi wokugaya, usebenzisa iphepha elinobukhulu noma unamathisela ama-coarse abresive, usayizi wezinhlayiyana we-80 # -280 #, usayizi omkhulu, kepha inani eliphakeme lokusika elijulile, indawo evuthayo ejulile, indawo evuthayo ejulile. Ngakho-ke, ukugaya okunolaka inqobo nje uma ikhanda noma isihlalo esiphansi lingasuswa ePokethe.

Esigangeni ukuqeda indawo enolaka yendawo yokubopha uphawu, ukuze uthuthukise ukwengeza indawo yokubekwa uphawu bese uqeda. Ukusetshenziswa kwephepha elimnandi noma unamathisela okuhle, usayizi wezinhlayiyana we-280 # -w5, usayizi omuhle, usika inani elincane, usiza ukunciphisa ubulukhuni; Isikhathi esifanayo kufanele sithathelwe indawo ngamathuluzi okucwaninga okuhambisanayo, amathuluzi okucwaninga kufanele ahlanzeke. Ngemuva kokugaya, indawo yokuxhumana ye-valve kufanele ifinyelele ekukhanyeni. Njengepensela noma isihlalo se-valve lapho kudonsela umgwaqo ombalwa, ikhanda le-valve noma isihlalo ngokumelene nokukhanya okukhanyayo, kufanele kusulwe umugqa wepensela.

Ukugaya okuhle isinyathelo sokugcina sokugaya kwe-valve, ikakhulukazi ukuthuthukisa ukuqedwa kwendawo yokubekwa uphawu. Ukugaya okuhle kungaba yi-W5 noma i-Amafutha amancane kanye no-Oyili, i-Karasene nezinye izisulu, ngekhanda le-valve ngokumelene nesihlalo se-valve egaya, ngaphandle kombukiso, kuyasiza kakhulu ebusweni bokuvalelisa. Ukugaya ngokuvamile iwashi kuya ku-60-100 ° noma ngakho-ke, bese uguqula indlela ephambene 40-90 ° noma ukugaya isikhashana, kufanele ubheke kahle i-shiny. Umugqa omncane kakhulu wombuthano, umbala oya emnyama nomnyama lapho uwoyela bese ugcoba kahle kaningana, usule nge-gauze ehlanzekile. Ngemuva kokugaya, bese uqeda ezinye iziphambeko, lowo mhlangano kufanele ube masisha ngokushesha, ukuze ungalimazi ikhanda le-valve elibunjiwe.

Ukugaya okwenziwa ngesandla kungakhathalekile ukutadisha okunzima noma okuhle, kuhlala kuphakama kuyo yonke indawo, phansi; ukujikeleza, ukubuyisa; Ukuthepha, ukubuyela emuva neminye imisebenzi ehlanganiswe nenqubo yokugaya. Injongo yayo ukugwema ukuphindaphinda kwethrekhi okuhlangene, ithuluzi lokugaya kanye nendawo yokubopha uphawu ukuze kugaye ukugaya, ukuthuthukisa indawo yokubekwa uphawu bese uqeda. 3, isigaba sokuhlola

Enqubweni yokugaya kwesinye isikhathi kuhlale kusebenza esigabeni sokuhlola, inhloso ukugcina lolo hlobo, qaphela, ukuze ikhwalithi yokugaya ihlangabezane nezidingo zobuchwepheshe. Kumele kwaziwe ukuthi ukugaya okuhlukile kwe-valve kufanele kusetshenziselwe ukuzivumelanisa nezimo ezinhlobonhlobo zokubekwa uphawu endaweni yamathuluzi okugaya ukuthuthukisa ukugaya ukusebenza kahle futhi kuqinisekiswe ikhwalithi yokugaya.

Ukugaya kwe-valve kungumsebenzi onobuhlakani kakhulu, udinga ukuqhubeka nokuthola ukuzilolonga, ukuhlola, ukuthuthukisa, futhi kwesinye isikhathi kufakwe kahle, ngoba ngemuva kokuvuza noma kungenxa yokuthi inqubo yokugaya ifakiwe, Induku yokugaya ayiqondile, i-skewed, noma i-angle yesilinganiso sethuluzi lokucwaninga liyaphambuka.

Njengoba i-abrasive iyingxube yomanzi onzima futhi ohlukumezayo, uketshezi oluhlukumezayo luyinto ejwayelekile kuphela kanye no-oyela wenjini. Ngakho-ke, ukukhetha okulungile kokuhlukumeza ingxenye ebaluleke kakhulu ukukhetha okulungile kokuhlupha. Ungayikhetha kanjani i-valve efanelekile?

I-Alumina (Al2o3) u-Alumina, owaziwa nangokuthi yi-Corrundum, ubulukhuni bawo buphakeme, ukusetshenziswa kuvame kakhulu. Ngokuvamile esetshenziselwa ukugaya i-iron iron, ithusi, insimbi nensimbi engenacala nezinye izinto zokwenza umsebenzi.

I-Silicon Carbide (Sic) i-Silicon Carbide inezinhlobo ezimbili eziluhlaza futhi ezimnyama, ubulukhuni buphakeme kune-alumina. Carbide Carbito eluhlaza eGreen yokugaya carbide ocebile; I-Carbide emnyama ye-Silicon yokugaya izinto zokugaya nezinto zokwakha ezithambile, njenge-cast iron, ithusi nokunye.

I-Boron Carbide (B4C) Hardnes Hardness Eyesibili kuphela ku-Diamond Powder kanye ne-Silicon Carbide kunokuba nzima, ikakhulukazi esetshenziselwa ukufaka indawo yokugaya i-camemond dring carbide, indawo enzima ye-chrome-plated.

I-Chromium Oxide (CR2O3) i-Chromium Oxide iyilukhuni eliphakeme futhi ihle kakhulu, insimbi elukhuni ivame ukusebenzisa ukugaya kwe-chromium oxis, kusetshenziselwa futhi ukuPheka.

I-Iron Oxide (FE2O3) I-Iron Oxide futhi iyi-valve enhle kakhulu, kepha ubulukhuni kanye nomphumela wokugaya kubi kakhulu kune-chromium oxide, inhloso efanayo ne-chromium oxide.
