Kaihanga Runga o te rakau chrome me te utu pai te rahi kua whakaritea

Taupānga: Ko te rakau Piston Chrome te nuinga e whakamahia ana i roto i te pneumatic hydraulic, miihini miihini, hanga motuka me teporo piston, Miihini kirihou poupou arataki, mihini takai, miihini ta, roera, miihini kakano, miihini kawe me te tuaka, te nekehanga raina me te tuaka whatu raina.

I. tukanga whakataki.

Ko teporo pistonhe whakakikorua chromium pakeke i runga i te mata tïpako rino kua whakakikoruatia ki te paparanga matotoru o te whakakikorua chromium me tona matotoru i roto i te nuinga o te 10 ki te 30 microns, ma te whakamahi i nga ahuatanga o te chromium ki te whakapai ake i nga mahi o nga waahanga, penei i te pakeke, te mau atete, te wera me te waikura.

Ko nga ahuatanga o te tukanga o te rakau piston whakakikoruatia chrome pakeke:

1) te kaha o te cathode o naianei he rite ki te 25% ~ 35%, me te tere o te whakahekenga.

2) pakeke tiketike (900 ~ 1200HV), kapiti whatunga kākahu me te mātotoru, pai abrasion ātete; Ka taea te whakaputa Microcracks, me te maha o microcracks taea tae 800-2000 mongamonga / cm (i runga i te hiahia), me te whakapai ake i te anti- kaha waikura.

3) pai te kaha marara o te pati whakakikorua, te matotoru rite o te paninga, e kore e ngawari ki te whakaputa i te ahua o te puku opupu taratara, me te ahua o te paparanga chromium he kanapa me te maeneene;

4) ko te paninga he kaha te kaha hononga ki te tïpako, me te pretreatment he rite ki te hangarau tuku iho, a he māmā ake te mahi i te tukanga tuku iho;

5) Ko te ihirangi o te chromium trivalent i roto i te pati ka whakaaetia kia whanui, a ko te tikanga kaore e hiahiatia kia whakamutua te electrolysis mo te trivalent chromium;

6) te otinga whakakikorua kahore he pūkōwhai, kahore huānga whenua onge, a kahore te waikura o te mea mahi kahore mana iti.

2. Te rere tukanga.

1).Tukatuka rere o te rakau piston waipēhi.

Te rakau hono ma te 35 maitai, te hangarau tukatuka: te whakamaroke i te hanga i te huri haere tonu te whakakeke i roto i te auau reo, te huri porotakaroa, te huri porotakaroa, te kutikuti porotakaroa te kutikuti. grinding.Hei whakapai ake i te kounga o te mata me te aukati waikura o te rakau piston, i taapirihia te mahi tino whakaoti i mua i te whakakikorua o te chrome.

2).Ko te mahi whakakikorua i te rakau piston.

Tirotiro i mua i te whakakikorua – te whakakikorua i te kete iri – te whakaheke matū, te hinu hiki hiko – te wai – te pikau whakakorikori – te horoi wai- te wa, te rakau piston whakakikorua chromium, te wai hangarua – te horoi wai – te wetewete i te taputapu whakairi – te tirotiro
