I-Electroplating kanye nokupholishwa kwe-piston rod

Induku ye-pistoni-electroplating I-piston rod yenziwe ngensimbi ye-carbon ephezulu ukuze ihlangabezane nezidingo zamandla, bese ifakwa nge-chrome ukuze iyenze ibe nesiphetho esiqinile, esibushelelezi, futhi esimelana nokugqwala.

I-Chromium electroplating iyinqubo ye-electrochemical eyinkimbinkimbi.Kuhlanganisa ukucwiliswa kubhavu wamakhemikhali oshisiswe nge-chromic acid.Izingxenye okufanele zifakwe, i-voltage isetshenziswa ngezingxenye ezimbili kanye nesisombululo samakhemikhali esiwuketshezi.Ngemva kwenqubo yamakhemikhali eyinkimbinkimbi, ngemva kwesikhathi esithile, ungqimba oluncane lwensimbi ye-chromium luzosetshenziswa kancane kancane.

Ishubhu lokupholisha lisebenzisa isondo lokupholisha elithambile, noma idiski yokupholisha emise okwe-disc, kanye nokunamathisela kokupholisha, okubuye kube ukuhuzuka, ukuze ucezu lomsebenzi lucutshungulwe kahle ukuze kutholwe indawo ephezulu.Kodwa ngenxa yokuthi ayinakho indawo eyireferensi eqinile enqubweni yokucubungula, ayikwazi ukuqeda iphutha lefomu nesikhundla.Nokho, uma iqhathaniswa nokucija, ingapholisha izindawo ezingavamile.

I-piston rod iyingxenye yokuxhuma esekela umsebenzi we-piston.Iningi lazo lisetshenziswa kumasilinda womoya kanye nezingxenye zokwenziwa kokunyakaza kwamasilinda womoya.Kuyingxenye ehambayo ehamba njalo kanye nezidingo zobuchwepheshe eziphakeme.Thatha isilinda somoya njengesibonelo, esakhiwe nge-cylinder barrel(cylinder tube), i-piston rod (cylinder rod), ipiston, kanye nesembozo sokuphela.Izinga lokucubungula kwalo lithinta ngqo impilo nokuthembeka kwawo wonke umkhiqizo.I-piston rod inezidingo eziphezulu zokucubungula, futhi ubulukhuni bayo obuphezulu budingeka ukuthi bube ngu-Ra0.4 ~ 0.8μm, futhi izidingo ze-coaxiality nokumelana nokugqoka ziqinile.

Izizathu zokushisa ngokweqile kwe-induku ye-piston(sebenzisa isilinda somoya):

1. I-piston rod kanye nebhokisi lokugxusha liyatsheka ngesikhathi sokuhlanganiswa, okubangela ukungqubuzana kwendawo, ngakho kufanele kulungiswe ngesikhathi;

2. Isiphethu sokubamba sendandatho yokuvala siqine kakhulu futhi ukungqubuzana kukhulu, ngakho kufanele kulungiswe ngendlela efanele;

3. I-axial clearance yendandatho yokuvala incane kakhulu, imvume ye-axial kufanele ilungiswe ngokuvumelana nezidingo ezicacisiwe;

4. Uma ukunikezwa kwamafutha kunganele, inani likawoyela kufanele lenyuswe ngendlela efanele;

5. I-piston rod nendandatho yophawu akusebenzi kahle, futhi ukugijima kufanele kuqiniswe ngesikhathi sokufanisa nokucwaninga;

6. Ukungcola okuxutshwe negesi namafutha kufanele kuhlanzwe futhi kugcinwe kuhlanzekile
