Umkhiqizi ophezulu wenduku ye-chrome enenani elihle losayizi owenziwe ngokwezifiso

Isicelo: I-Chrome Piston rod isetshenziswa kakhulu ku-hydraulic pneumatic, imishini yobunjiniyela, ukwakhiwa kwezimoto ngeinduku ye-piston, insika yepulasitiki yensika yomhlahlandlela, imishini yokupakisha, imishini yokunyathelisa, i-roller, imishini yendwangu, imishini yokuthutha ene-eksisi, ukunyakaza okuqondile okune-eksisi ekhanyayo yomugqa.

I. inqubo isingeniso.

Iinduku ye-pistonicwecwe eliqinile le-chromium endaweni yensimbi engaphansi embozwe ungqimba oluwugqinsi lwe-chromium plating futhi ukujiya kwayo kungama-microns ayi-10 kuye kwangama-30, kusetshenziswa izici ze-chromium ezithuthukisa ukusebenza kwezingxenye, njengokuqina, ukumelana nokuguga, ukumelana nokushisa nokungagqwali.

Izici zenqubo ye-hard chrome plated piston rod:

1) ukusebenza kahle kwamanje kwe-cathode kuphezulu njengo-25% ~ 35%, futhi izinga lokubeka lishesha kakhulu.

2) ubulukhuni obuphezulu (900 ~ 1200HV), ukuqhekeka kwenethiwekhi okufana nokuminyene, ukumelana okuhle kokuhuzuka; Ama-Microcracks angakhiqizwa, futhi inani lama-microcracks angafinyelela izingcezu ezingama-800-2000/cm (ngokwesidingo), futhi athuthukise i-anti- ikhono lokugqwala.

3) ikhono elihle lokuhlakazeka lokugeza okucwebezelayo, ukushuba komfaniswano we-coating, akulula ukukhiqiza isimo seqhubu elibi, nokubukeka kongqimba lwe-chromium kugqamile futhi kubushelelezi;

4) ukugqoka kunamandla okubopha okuqinile ne-substrate, futhi ukwelashwa kwangaphambili kufana nobuchwepheshe bendabuko, futhi ukusebenza kulula kunenqubo yendabuko;

5) okuqukethwe kwe-chromium eyi-trivalent kubhavu kuvunyelwe ukuthi kube banzi, futhi ngokuvamile akudingi ukunqanyulwa kwe-electrolysis ku-chromium eyi-trivalent;

6) ikhambi lokucwenga aliqukethe i-fluoride, azikho izakhi zomhlaba ezingavamile, futhi akukho ukugqwala kwendawo yokusebenza ngaphandle kwamandla aphansi.

2. Ukugeleza kwenqubo.

1).Ukugeleza kwenqubo ye-hydraulic piston rod.

Induku yokuxhuma kusetshenziswa insimbi engama-35, ubuchwepheshe bokucubungula: ukwakheka okubandayo okukhangayo okuphendukayo okuqhubekayo kokuqina kokufakwa kwefrikhwensi okuphakathi, ukugaya okuyisilinda, isilinda sokugaya esicolekile isigaba sokugunda esiyisilinda sokugaya. ekuqedeni isigaba sokucheba i-chromium kuya ku-hydrogen tempering. Ukugaya.Ukuze kuthuthukiswe ikhwalithi engaphezulu nokumelana nokugqwala kwe-piston rod, inqubo yokuqeda kahle kakhulu yanezelwa ngaphambi kokufakwa kwe-chrome.

2).Inqubo ye-Piston rod Plating.

Ukuhlolwa ngaphambi kokucwenga - indawo yokulengiswa kwephakethe - ukuwohloka kwamakhemikhali, uwoyela wokuphakamisa ugesi - amanzi - ukukhethwa kokuvula - ukugeza amanzi- okwamanje, i-piston rod chromium plating, amanzi agaywa kabusha - ukuwashwa kwamanzi - ukuthulula into elengayo - ukuhlolwa
