Njengengxenye eyinhloko ye-hydraulic cylinder, i-piston rod isetshenziswa ezimweni ezinzima ezizungezile kanye nezimo ezonakalisayo;Ngakho-ke, ungqimba oluvikelayo lwekhwalithi ephezulu lubalulekile.Njengamanje, i-electroplating hard chrome iyindlela esabalele.Ngenxa yokusebenza kwayo okunamandla nezindleko eziphansi, i-electroplated hard chrome iyindlela evamile yokwelashwa kwenduku yepiston.
Imibandela ye-piston rod coating
1) Ukuqina
Ukuqina kuyisici esibalulekile sezintambo ze-piston.Izembatho ezibonisa ukuqina okubi noma ukungabi qinile ngokwanele azikwazanga ukumunca amandla amaningi ngesikhathi itshe le-angular noma uhlaka oluqinile lushaya intonga ye-piston, ukulimala kwendawo bese kwenzeka kalula, futhi isilinda esisebenza ngamanzi ngeke sisakwazi ukusebenza ngokushesha ngenxa yokumboza i-delamination noma ukucwayiza.
Ukuhlolwa komthelela ukuhlola okuguquguqukayo lapho isifanekiso esikhethiwe sivame ukushaywa futhi siphulwe yi-swing pendulum.Izivivinyo ezivame kakhulu zalolu hlobo ukuhlolwa kwe-Charpy V-notch kanye nokuhlolwa kwe-Izod okuchazwe ku-ASTM E23.Umehluko oyinhloko phakathi kwalokhu kuhlola okubili yindlela okugxilwe ngayo kusifanekiso.
2) Ukumelana nokugqwala
Ngenxa yesimo esingesihle sokusebenza, ukumelana nokugqwala kubaluleke kakhulu embotsheni yenduku ye-hydraulic cylinder piston.Ukuhlolwa kwesifutho sikasawoti kuyindlela evamile yokuhlola ejwayelekile esetshenziselwa ukuhlola ukumelana nokugqwala kwe-hydraulic cylinder piston rod coating;kuwukuhlola okusheshisa ukugqwala futhi ukubukeka kwemikhiqizo yokugqwala kuhlolwa ngemva kwesikhathi esithile.
Imishini yokuhlola njengoba kukhonjisiwe emfanekisweni wesi-4 inegumbi lokuhlola elivaliwe, lapho isixazululo esinosawoti, ikakhulukazi isisombululo se-sodium chloride, sifuthwa ngombhobho.Lokhu kukhiqiza indawo eyonakalisayo ekamelweni futhi ngaleyo ndlela, izingxenye ezikulo zihlaselwa ngaphansi kwalesi simo esibi kakhulu sokugqwala.Ukuhlolwa okwenziwe ngesisombululo se-NaCl kwaziwa ngokuthi yi-NSS (i-neutral salt spray).Imiphumela ngokuvamile ihlolwa njengamahora okuhlola ku-NSS ngaphandle kokuvela kwemikhiqizo egqwalile.Ezinye izixazululo yi-ASS (ukuhlolwa kwe-acetic acid) kanye ne-CASS (i-acetic acid enokuhlolwa kwe-copper chloride).Ukwakhiwa kwegumbi, inqubo yokuhlola, kanye nemingcele yokuhlola kumiswa ngendlela efanayo ngaphansi kwamazinga kazwelonke nawamazwe ngamazwe, njenge-ASTM B117, DIN 50021, ne-ISO 9227. Ngemva kwesikhathi sokuhlola, isampula lingalinganiswa ngendawo egqwalile kusetshenziswa inkomba yereferensi njengoba kubonisiwe. etafuleni 1.
I-3) Ukumelana nokugqoka
Njengeyunithi yokudlulisa amandla, induku yepiston idinga ukuya phambili futhi emuva njalo, ngesikhathi esifanayo ukuguga kwenzeka ngesikhathi sokumboza isilayidi ngokumelene nesilinda.Ngakho-ke ukumelana nokugqoka kuyisidingo esibalulekile sempilo ye-piston rod.Ukuqina kobuso kuyipharamitha eyinhloko yokumelana nokugqokwa.Ngaphandle kokuqina, ukumelana nokugqwala kanye nokumelana nokugqokwa, ngokuya ngamazinga emboni ahlukahlukene kanye nezidingo zamakhasimende, enye imibandela yokumbozwa kwezinduku ze-piston ibalwe kuthebula2.
Ukuze uthole ulwazi olwengeziwe mayelana namasilinda amanzi, amayunithi wamandla asebenza ngogesi, sicela ukhululeke ukusithinta ngokuthi:sales@fasthydraulic.com
