Faka uphawu kuhlelo lokusebenza oluthintekile yini
Sithole inkinga ithimba labalungisa elibhekene nayo.Lapho sebeshintshela kuwoyela omusha nangcono, izimvu zamanzi zaqala ukuvuza.Amafutha akusilinda atholakale engcoliswe izinsalela zensimbi.Ingabe uthole inkinga kusilinda piston?
Izindleko ezihlobene nokuchitheka kwengozi ngokuvamile zanele ukuze zikwenze ubuyekeze izici ezithile zomsebenzi wakho.Ngokusekelwe olwazini olunikeziwe, inkinga ibonakala ikuhlelo lwe-hydraulic noma ama-seal nama-piston cylinders e-compressor enkulu ye-piston.Impendulo yalo mbuzo iwukuthi zombili lezi zinkinga, kanye nenqwaba yezinye izici, kungabangela ukuvuza uphawu.Kunoma yikuphi, kufanele kuhlaziywe umsuka wembangela ukuze kutholwe umthombo wenkinga.
Ukuze unciphise izinkinga zokuvuza kwezimpawu futhi ukhethe isisombululo esingcono kakhulu, kufanele uqale ucabangele uhlobo lophawu olusetshenziswayo.Kunezinhlobo ezine eziyinhloko zezimpawu: ama-static seal (ama-gaskets kanye nama-o-rings), izimpawu zokuthintana ezishintshayo (i-lip seal kanye ne-mechanical face seal), izigxivizo ezishintshayo ezingathintani (i-labyrinth seal), kanye nezimpawu zokuxhumana ezishintshayo (amasongo e-piston. nama-piston seal).I-Rod Packing) okuyizinhlobo zezimpawu okuxoxwe ngazo lapha.
Inhloso yophawu ukuvimbela ukungcola ukuthi kungangeni ngenkathi kugcinwe okokugcoba.Ama-seal aphindaphindayo azama ukuvala izindawo zensimbi ezishelelayo.Nge-stroke ngayinye, uwoyela ushiya uhlelo futhi ukungcola kudonselwa emuva, ngakho-ke ukunquma imbangela yokuhluleka kwezimpawu kuvame ukuba nzima, futhi kunzima nakakhulu ukulungisa.
Izimpawu zingase zithinteke izici eziningi, okuhlanganisa ukuthambisa, izinga lokushisa, ukucindezela, isivinini se-shaft, nokungahambi kahle.Izigxivizo eziningi zikawoyela ezijwayelekile zenzelwe ukusetshenziswa kwengcindezi ephansi.Izigxivizo nazo zidinga ukugcotshwa njalo ngamafutha okusebenza aphezulu we-viscosity efanele ehambisana nempahla yophawu.Izinga lokushisa likawoyela nezinga lokushisa le-ambient kufanele kuhlolwe njengoba izinga lokushisa alikwazi ukudlula ububanzi be-elastomer evalayo.Ukwengeza, ukungahambi kahle kwe-shaft kanye ne-bore kungabangela ukuguga ukuthi kugxilwe ohlangothini olulodwa lwe-seal.Kodwa-ke, isivinini se-shaft singenye yezinto ezibaluleke kakhulu ekukhetheni uphawu futhi inquma zonke ezinye izici.
