Wopanga Pamwamba pa ndodo ya chrome yokhala ndi mtengo wabwino wosinthidwa makonda

Kugwiritsa ntchito: Chrome Piston ndodo imagwiritsidwa ntchito kwambiri mu hydraulic pneumatic, engineering engineering, kupanga magalimoto ndipisitoni ndodo, makina opangira pulasitiki, makina onyamula katundu, makina osindikizira, zodzigudubuza, makina opangira nsalu, makina oyendera okhala ndi olamulira, kuyenda kwa mzere wokhala ndi mzere wowongolera.

I. ndondomeko yoyambira.

Thepisitoni ndodondi chitsulo cholimba cha chromium plating pazitsulo zachitsulo zomwe zimakutidwa ndi plating ya chromium ndipo makulidwe ake amakhala pafupifupi ma microns 10 mpaka 30, pogwiritsa ntchito mawonekedwe a chromium amawongolera magwiridwe antchito a magawo, monga kulimba, kukana kuvala, kukana kutentha komanso kusamva dzimbiri.

Zochita zachitsulo cholimba cha chrome chodzaza piston:

1) mphamvu yapano ya cathode ndi yokwera kwambiri ngati 25% ~ 35%, ndipo kuchuluka kwamafuta kumathamanga kwambiri.

2) mkulu kuuma (900 ~ 1200HV), yunifolomu ndi wandiweyani ming'alu maukonde, zabwino abrasion kukana;Microcracks akhoza kupangidwa, ndi chiwerengero cha microcracks angafikire 800-2000 zidutswa/cm (malinga ndi kufunika), ndi kusintha odana- kuthekera kwa dzimbiri.

3) bwino kubalalitsidwa luso la plating kusamba, makulidwe yunifolomu ❖ kuyanika, si zophweka kubala chodabwitsa akhakula chithuza chotupa, ndi maonekedwe a chromium wosanjikiza yowala ndi yosalala;

4) ❖ kuyanika kumakhala ndi mphamvu zomangirira mwamphamvu ndi gawo lapansi, ndipo pretreatment ndi yofanana ndi ukadaulo wachikhalidwe, ndipo ntchitoyo ndiyosavuta kuposa momwe zimakhalira;

5) zili trivalent chromium mu kusamba amaloledwa kukhala lonse, ndipo nthawi zambiri safuna kusiya electrolysis kwa trivalent chromium;

6) yankho la plating liribe fluoride, palibe zinthu zapadziko lapansi zosowa, ndipo palibe dzimbiri la chogwirira ntchito popanda mphamvu yochepa.

2. Njira kuyenda.

1).Njira yoyendetsera hydraulic piston rod.

Kulumikiza ndodo pogwiritsa ntchito zitsulo 35, ukadaulo wopangira: kuzizira kumapanga kutembenuza kopitilira sing'anga pafupipafupi kukulitsa kulimba, kupukuta kwa cylindrical, kupukuta kozungulira, kumeta ubweya wa cylindrical kumeta chigawo. Kuti apititse patsogolo mawonekedwe a pamwamba ndi kukana kwa dzimbiri kwa ndodo ya pisitoni, njira yomaliza yomaliza idawonjezedwa pamaso pa chrome plating.

2).Njira yopangira piston.

Kuyang'ana musanayike - paketi yolendewera - kutsitsa kwamankhwala, mafuta okweza magetsi - madzi - kuyambitsa pickling - kutsuka madzi - mphindi, piston ndodo chromium plating, zobwezeretsanso madzi - kutsuka madzi - kutsitsa zolendewera - kuyendera
