Monga gawo lalikulu la silinda ya hydraulic, ndodo ya pistoni imagwiritsidwa ntchito molimba mozungulira komanso zowononga;Chifukwa chake, chitetezo chapamwamba kwambiri ndikofunikira.Pakadali pano, electroplating hard chrome ndi njira yofala.Chifukwa cha magwiridwe ake amphamvu komanso mtengo wotsika, electroplated hard chrome ndi njira yodziwika bwino yochizira ndodo ya piston.
Zofunikira zokutira ndodo ya piston
1) Kulimba
Kulimba ndi khalidwe lofunikira la zokutira ndodo za pistoni.Zovala zosonyeza kulimba kosalimba kapena kusakhala wolimba mokwanira sizikanatha kuyamwa mphamvu zambiri pamwala wokhotakhota kapena grit yolimba ikagunda ndodo ya pisitoni, kuwonongeka kwa pamwamba kumachitika mosavuta, ndipo silinda ya hydraulic idzalephera kugwira ntchito nthawi yomweyo chifukwa cha zokutira kapena kuphulika.
Kuyesa kwamphamvu ndi kuyesa kwamphamvu komwe chitsanzo chosankhidwa nthawi zambiri chimakanthidwa ndikusweka ndi swing pendulum.Mayeso odziwika kwambiri amtunduwu ndi mayeso a Charpy V-notch ndi mayeso a Izod omwe akufotokozedwa mu ASTM E23.Kusiyana kwakukulu pakati pa mayesero awiriwa ndi momwe chitsanzocho chimakhazikitsidwa.
2) Kukana dzimbiri
Chifukwa cha malo osagwira ntchito, kukana kwa dzimbiri ndikofunikira kwambiri pakuyala ndodo ya hydraulic cylinder piston.Mayeso opopera Mchere ndi njira yoyeserera yokhazikika yomwe imagwiritsidwa ntchito poyang'ana kukana kwa dzimbiri kwa hydraulic cylinder piston rod cording;ndiyeso yofulumira yolimbana ndi dzimbiri ndipo mawonekedwe azinthu zowononga amawunikidwa pakapita nthawi.
Chida choyesera monga momwe chikuwonetsedwera m'chithunzi 4 chili ndi chipinda choyezera chotsekedwa, momwe yankho la mchere, makamaka yankho la sodium chloride, limapopera ndi mphuno.Izi zimapanga malo owononga m'chipindamo, motero, mbali zake zimawukiridwa ndi mpweya woipawu.Mayesero opangidwa ndi yankho la NaCl amadziwika kuti NSS (kupopera kopanda mchere wapakati).Zotsatira nthawi zambiri zimawunikidwa ngati maola oyesera mu NSS popanda kuoneka kwa zinthu zowonongeka.Njira zina ndi ASS (acetic acid test) ndi CASS (acetic acid with copper chloride test).Kumanga kwa chipinda, njira zoyesera, ndi magawo oyesera ndizokhazikika pansi pa miyezo ya dziko ndi mayiko, monga ASTM B117, DIN 50021, ndi ISO 9227. Pambuyo pa nthawi yoyesera, chitsanzocho chikhoza kuvoteredwa molingana ndi malo ochita dzimbiri pogwiritsa ntchito ndondomeko yowonetsera. mu table 1.
3) Valani kukana
Monga gawo lotumizira mphamvu, ndodo ya pisitoni imayenera kusuntha ndikubwerera pafupipafupi, nthawi yomweyo kuvala kumachitika panthawi yotchinga pamwamba pa silinda yosindikiza.Chifukwa chake kuvala kukana ndichinthu chofunikira kwambiri pa moyo wa piston.Kuuma kwa pamwamba ndiye gawo lofunikira pakukana kuvala.Kupatula kulimba, kukana kwa dzimbiri komanso kukana kuvala, malinga ndi miyezo yosiyanasiyana yamakampani ndi zofunika zamakasitomala, njira zina za zokutira ndodo za pisitoni zalembedwa patebulo2.
