Njengenxalenye ephambili ye-hydraulic cylinder, intonga ye-piston isetyenziswe kwiimeko ezinzima ezijikelezayo kunye neemeko ezinobungozi;Ngenxa yoko, umaleko wokhuselo olukumgangatho ophezulu ubalulekile.Okwangoku, i-electroplating hard chrome yindlela ebanzi.Ngenxa yokusebenza kwayo okunamandla kunye neendleko eziphantsi, i-electroplated hard chrome yindlela eqhelekileyo yonyango lwentonga yepiston.
Iikhrayitheriya zokugquma intonga yepiston
1) Ukuqina
Ukuqina luphawu olubalulekileyo lweentonga zepiston.Iingubo ezibonisa ukuqina okulambathayo okanye ukungomelelanga ngokwaneleyo akukwazanga ukufunxa amandla amaninzi ngexesha lelitye le-angular okanye igrit eqinileyo ibetha intonga yepiston, umonakalo womphezulu wenzeke ngokulula, kwaye isilinda sobuchwephesha bokwenza ulwelo siya kusilela ukusebenza ngoko nangoko ngenxa yokwaleka kwe-delamination okanye ukugqabhuka.
Uvavanyo lwempembelelo luvavanyo oluguquguqukayo apho umzekelo okhethiweyo udla ngokubethelwa kwaye uphulwe yi-swing pendulum.Iimvavanyo eziqhelekileyo zolu hlobo luvavanyo lwe-Charpy V-notch kunye novavanyo lwe-Izod oluchazwe kwi-ASTM E23.Umahluko osisiseko phakathi kweemvavanyo ezimbini yindlela emiselweyo kumzekelo.
2) Ukumelana nokubola
Ngenxa yendawo yokusebenza ehlwempuzekileyo, ukuxhathisa umhlwa kubaluleke kakhulu kwi-hydraulic cylinder piston rod coating.Uvavanyo lwesitshizi seTyuwa luvavanyo oluqhelekileyo olusemgangathweni olusetyenziselwa ukujonga ukuxhathisa ukubola kwe-hydraulic cylinder piston rod coating;luvavanyo olukhawulezayo lokuxhathisa umhlwa kunye nenkangeleko yeemveliso zokuhlwa zivandlakanywa emva kwethuba lexesha.
Izixhobo zokuvavanya njengoko kuboniswe kumfanekiso we-4 ziquka igumbi lokuvavanya elivaliweyo, apho isisombululo esinetyuwa, ngokukodwa isisombululo se-sodium chloride, sitshizwa nge-nozzle.Oku kuvelisa imeko-bume eyonakalisayo kwigumbi kwaye ke, iinxalenye zayo zihlaselwa phantsi kwesi simo sezulu esibi kakhulu.Iimvavanyo ezenziwe ngesisombululo se-NaCl zaziwa njenge-NSS (i-neutral salt spray).Iziphumo zivandlakanywa njengeeyure zovavanyo kwi-NSS ngaphandle kokuvela kweemveliso zomhlwa.Ezinye izisombululo ziyi-ASS (uvavanyo lwe-acetic acid) kunye ne-CASS (i-acetic acid kunye novavanyo lwe-copper chloride).Ukwakhiwa kwegumbi, inkqubo yovavanyo, kunye neeparamitha zovavanyo zisemgangathweni phantsi kwemigangatho yesizwe neyezizwe ngezizwe, efana ne-ASTM B117, DIN 50021, kunye ne-ISO 9227. Emva kobude bexesha lovavanyo, isampulu inokulinganiswa ngokwendawo enomhlwa kusetyenziswa umgangatho wereferensi njengoko kubonisiwe. kwitheyibhile yoku-1.
3) Ukugqoka ukuxhathisa
Njengeyunithi yothumelo lwamandla, intonga yepiston idinga ukuhamba phambili kwaye ibuye umva rhoqo, kwangaxeshanye ukunxitywa kwenzeka ngexesha lokugquma komphezulu isilayidi ngokuchasene nokutywinwa kwesilinda.Yiyo loo nto ukuxhathisa ukunxiba kukwayinto ebalulekileyo kubomi bentonga yepiston.Ubulukhuni bomphezulu yiparameter ephambili yokumelana nokunxiba.Ngaphandle kokuqina, ukuxhathisa umhlwa kunye nokunganyangeki kokunxiba, ngokwemigangatho eyahlukeneyo yoshishino kunye neemfuno zabathengi, enye ikhrayitheriya yeentonga zepiston zidweliswe kwitheyibhile2.
Ngolwazi oluthe kratya malunga neesilinda zehydraulic, iiyunithi zamandla oxinzelelo lwendalo, nceda uzive ukhululekile ukuqhagamshelana nathi:sales@fasthydraulic.com
