U thibela ho bola joang ka li-valve tsa aluminium tse sebelisoang metsing a leoatle?
Li-alloys tse tloaelehileng tsa aluminium ha li khothalletsoe ho pepesehela metsi a leoatle ka kotloloho ka lebaka la kutu ea galvanic. Bakeng sa tikoloho ea leoatle, re khothaletsa ho sebelisa li-alloys tse khethehileng tsa boemo ba metsing joalo ka A360 kapa ho sebelisa litlolo tse sireletsang joalo ka epoxy e boima kapa anodizing. Ho arola aluminium ho litšepe tse ling ka mekhatlo ea dielectric le hona ho bohlokoa.
Nako e tloaelehileng ea ho tsamaisa li-valve tsa OEM ke efe?
Linako tse etellang pele li fapana ho latela ho rarahana le molumo. Mehlala ea prototype hangata e ka hlahisoa nakong ea libeke tse 2-4. Hangata tlhahiso e felletseng e nka libeke tse 4-8 kamora tumello ea lisebelisoa. Liodara tse potlakileng li ka etsoa ho latela boholo ba hona joale le lintho tse fumanehang.
A na u fana ka setifikeiti sa lintho tse bonahalang bakeng sa libapali tsa hau?
Ee, re fana ka Litlaleho tsa Teko ea Material (MTRs) bakeng sa sehlopha se seng le se seng. Litokomane tsena li kenyelletsa tlhahlobo ea sebopeho sa lik'hemik'hale le liphetho tsa tlhahlobo ea thepa ea mochini, ho netefatsa hore ho latela litekanyetso tse boletsoeng joalo ka ASTM kapa ISO.

Qetello: Ho sebelisana 'moho bakeng sa Nepahetseng le Ts'ebetso
Lisebelisoa tsa aluminium tsa valve ha li na likarolo tsa tšepe feela; ke lintlha tsa bohlokoa tse netefatsang polokeho, ts'ebetso le ts'epahalo ea litsamaiso tsa taolo ea mokelikeli. Ka ho sebelisa mekhoa e tsoetseng pele ea tlhahiso, taolo e matla ea boleng, le boiphihlelo bo tebileng ba thepa, re fana ka litharollo tsa OEM tse fihlelang litekanyetso tse phahameng ka ho fetisisa tsa indasteri.
Hore na o hloka li-die-cast tsa boleng bo holimo bakeng sa sistimi ea HVAC kapa li-valve tsa lehlabathe tse nepahetseng bakeng sa ts'ebetso ea indasteri, boitlamo ba rona ba bokhabane bo netefatsa hore merero ea hau e ea atleha. Re utloisisa metako ea tšepe ea aluminium le litlhoko tse ikhethang tsa lisebelisoa tsa li-valve, tse re lumellang ho fana ka litharollo tse hlophisitsoeng tse ntlafatsang ts'ebetso le litšenyehelo.
Ho khetha molekane ea nepahetseng oa tlhahiso ho kenyelletsa ho sheba ka nqane ho theko ho nahana ka bokhoni ba tekheniki, netefatso ea boleng, le ts'ehetso ea tšebelisano. Sehlopha sa rona se itokiselitse ho u thusa ho tsamaisana le mathata a tlhahiso ea li-valve tse tloaelehileng, ho tloha lipuisanong tsa pele tsa moralo ho isa ho phano ea ho qetela.
Bakeng sa likhoebo tse batlang tse tšepahalang, tsa boleng bo holimo li-valve aluminium castings, re u mema hore u buisane ka litlhoko tsa hau tse khethehileng. E re re u thuse ho etsa litharollo tse phahameng tsa taolo ea mokelikeli tse emelang nako.
Lekola mefuta ea rona e felletseng ea litharollo tsa ho lahla li-valve 'me u kope qotso kajeno.
