Electrostatic Spraying Process embonini yamavalvu

Eminyakeni yamuva, kanye nentuthuko eqhubekayo yesayensi nobuchwepheshe, ezifuywayo valve emakethe, kodwa futhi high-tech, high-parameter, ukumelana nokugqwala okuqinile, isiqondiso ukuphila okusezingeni eliphezulu. Lesi siqondiso sokuthuthukiswa siphinde sibeke phambili izidingo eziphakeme ekunambeni kwe-valve. Electrostatic sishaye ubuchwepheshe imakethe yalesi sici kuyinto ductile iron valve indlela evamile, kulo nyaka futhi ukwelashwa surface valve iye kabanzi kugqugquzelwa, kodwa ngaphandle ukuhlaziya ngokucophelela ezihlukahlukene izinto kanye nenqubo ngaphambi ngenxa yokukhiqiza electrostatic sishaye imishini. , Ngoba izici ezihlukene zezinto ezahlukene kanye nokucubungula ubuchwepheshe ekukhethweni kwezidingo zemishini yokufafaza i-electrostatic. Kudinga okungaphezu kwehhavinirall ukusebenza kwemishini yokufafaza nge-electrostatic, ukwenziwa kahle kwezidingo zokuvikela imvelo, izinga lokubuyiswa kwempushana ku-powder kufanele likhathazeke ngezidingo zokumboza ezidingekayo ukuze kubhekwane nezinhlobo ezahlukene zezinto zobuciko ukuthuthukiswa okuyingqayizivele kwemboni nezimo zemakethe nokunye.

Lapha ngifingqa ngalezi zinyathelo ezimbalwa zokuqapha lapho i-valve yasekhaya ifafaza nge-electrostatic:

1. Inqubo yokwelashwa kwangaphambili. Indlela yokubumba yokusakaza yokucubungula i-oxide engaphezulu kanye nokuqhunyiswa kwesihlabathi. Zama ukungasebenzisi indlela yokudubula. I-valve idinga ukunemba okuphezulu, ikakhulukazi ngaphakathi kwe-valve, kuzoba khona indawo ethile yendawo eqhunyiswa ngaphansi. Ukulawulwa kwe-sandblasting okungcono kokuqina nokushelela kwendawo. Kodwa ukusebenza kahle kwayo kuyabambezela uma kuqhathaniswa nezinkinga zayo. General izimfuneko zokuqeda phezulu ukuze kuzuzwe izinga le-Sa3, ubukhulu obungaphezulu be-Ra value engu-45 ~ 70um.
2. Imishini yokwehlisa amafutha kanye ne-phosphating akumele ibe ngaphansi. Uma indawo yasendaweni enamafutha ngaphambi kokungena egunjini lempushana, okokuqala kwavela okokunamathela okunamafutha kuzacile kakhulu. Kulandelwa ukunganamatheli kahle kwefilimu, futhi kulula ukuyishintsha. Ekugcineni, enamathela umbala umehluko usobala.
3. Ama-valve castings Ngokuvamile aminyene, futhi kufanele abe nesikhathi esanele sokushisa esidingekayo. Leli phuzu liwufuzoralkulula ukungakunaki. Kufanele kube okunengqondo kuhhavinirall umklamo we i-powder coating i-valve yepayipi Shisisa ihhavini ukuze usebenzise isikhathi esanele.
4. Kumavalvu amakhulu angaphandle, adinga umsebenzi osindayo, ukukhethwa kwe-thermosetting powder coating angeke kube ngenxa ye-powder coating eshibhile ngakho-ke abasebenzisi kufanele basebenzise i-epoxy powder ehlanzekile, kanye nezimfuneko ezikhishwe umenzi wemibiko yokuhlolwa kwegunya. Endabeni yezindlela ezifanayo zokugqoka, i-powder coating yasendlini esetshenziswa ngaphandle, impilo yokugqoka yezimo ezijwayelekile izinyanga ezingu-6. Ukusetshenziswa kwe-powder esindayo kungafinyelela iminyaka engaphezu kwemithathu.
5. Izinkinga zokumboza i-valve. Abakhiqizi abaningi banaka ukubukeka kombala, futhi abazange banake ngempela ikhwalithi yokugqoka. Eqinisweni, umbala oyinhloko kanye nempushana, kodwa futhi izindlela ezibalulekile nezifafaza.
