Ungakhetha kanjani izihlungi ze-hydraulic pressure?
Umsebenzisi kufanele aqale aqonde isimo sesistimu yakhe ye-hydraulic, bese ukhetha okokuhlunga. Umgomo wokukhetha uthi: impilo ende yesevisi, kulula ukuyisebenzisa, nomphumela owanelisayo wokuhlunga.
Izinto ezinomthelela empilweni yesevisi yokuhlungaIsici sokuhlunga esifakwe ngaphakathi kwesihlungi esisebenza ngaphansi komhlaba sibizwa ngokuthi i-elementi yokuhlunga, futhi into yaso eyinhloko isikrini sokuhlunga. Isihlungi ngokuyinhloko siyimeshi elukiwe, isihlungi sephepha, isihlungi se-fiber yengilazi, isihlungi se-fiber yamakhemikhali kanye nesihlungi se-fiber yensimbi. Izihlungi zemidiya ezakhiwe ngocingo nemicu ehlukahlukene zintekenteke kakhulu ekuthunjweni, nakuba inqubo yokukhiqiza yalezi zinto zokwakha ithuthukiswa (njengalezi: ulayini, ukufakwa kwe-resin), kodwa kusenemikhawulo ezimeni zokusebenza. Izinto eziyinhloko ezithinta impilo yokuhlunga zichazwe kanje.
1. Ukwehla kokucindezela kuzo zombili iziphetho zesihlungiUma amafutha edlula isici sokuhlunga, ukwehla kokucindezela okuthile kuzokwenziwa kuzo zombili iziphetho, futhi inani elithile lokwehla kokucindezela lincike esakhiweni nasekugelezeni kwendawo yesici sokuhlunga. Lapho isici sokuhlunga samukela ukungcola emafutheni, lokhu kungcola kuzohlala phezulu noma ngaphakathi kwesici sokuhlunga, ukuvikela noma ukuvimbela okunye ngokusebenzisa izimbobo noma iziteshi, ukuze indawo yokugeleza ephumelelayo inciphe, ukuze ukucindezela kwehle ngesici sokuhlunga kwandiswe. Njengoba ukungcola okuvinjwe isici sokuhlunga kuqhubeka nokwanda, ukucindezela kwehla ngaphambi nangemva kwesici sokuhlunga nakho kuyanda. Lezi zinhlayiya ezincishisiwe zizokhama emigodini ye-medium futhi ziphinde zingene ohlelweni; Ukwehla kwengcindezi kuzophinde kwandise usayizi wembobo yasekuqaleni, kushintshe ukusebenza kwesici sokuhlunga futhi kunciphise ukusebenza kahle. Uma ukwehla kwengcindezi kukukhulu kakhulu, kudlula amandla esakhiwo se-elementi yokuhlunga, isici sokuhlunga sizoba isicaba futhi siwe, ukuze umsebenzi wesihlungi ulahleke. Ukuze wenze isici sokuhlunga sibe namandla anele ngaphakathi kwebanga lokucindezela kokusebenza kwesistimu, ukucindezela okuncane okungabangela isici sokuhlunga ukuthi sibekwe sicaba ngokuvamile sisethwa njengezikhathi ezingu-1.5 zokucindezela kokusebenza kwesistimu. Lokhu kuyiqiniso, lapho uwoyela kufanele aphoqwe ngesendlalelo sokuhlunga ngaphandle kwe-valve ye-bypass. Lo mklamo uvame ukuvela ezihlungini zamapayipi anengcindezi ephezulu, futhi amandla esici sokuhlunga kufanele aqiniswe kunethiwekhi yamathambo yangaphakathi kanye ne-lining network (seeiso 2941, iso 16889, iso 3968).
2. Ukuhambisana kwesici sokuhlunga namafuthaIsihlungi siqukethe kokubili izakhi zokuhlunga zensimbi kanye nezakhi zokuhlunga okungezona ezensimbi, okuyiziningi, futhi zonke zinenkinga yokuthi zingahambisana yini namafutha ohlelweni. Lokhu kufaka phakathi ukuhambisana kwezinguquko zamakhemikhali nezinguquko emiphumeleni yokushisa. Ikakhulukazi ezimweni zokushisa eziphakeme azikwazi ukuthinteka kubaluleke kakhulu. Ngakho-ke, izici ezihlukahlukene zokuhlunga kufanele zihlolwe ukuhambisana nowoyela emazingeni okushisa aphezulu (bona ISO 2943).
3.Umthelela wokushisa okuphansi komsebenziIsistimu esebenza emazingeni okushisa aphansi nayo inomphumela omubi kusihlungi. Ngoba emazingeni okushisa aphansi, ezinye izinto ezingezona ezensimbi kusici sokuhlunga zizoba ntekenteke kakhulu; Futhi ekushiseni okuphansi, ukwanda kwe-viscosity yamafutha kuzobangela ukwehla kwengcindezi, okulula ukubangela ukuqhekeka kwezinto eziphakathi. Ukuze uhlole isimo sokusebenza sesihlungi ekushiseni okuphansi, ukuhlolwa "kokuqala okubandayo" kwesistimu kufanele kwenziwe ekushiseni okuphansi kokugcina kwesistimu. I-MIL-F-8815 inenqubo yokuhlola ekhethekile. I-China Aviation Standard HB 6779-93 nayo inezinhlinzeko.
4. Ukugeleza kwamafutha ngezikhathi ezithileUkugeleza kwamafutha ohlelweni ngokuvamile akuzinzile. Uma izinga lokugeleza lishintsha, lizobangela ukugoba kwesici sokuhlunga. Endabeni yokugeleza ngezikhathi ezithile, ngenxa yokuguqulwa okuphindaphindiwe kwempahla ephakathi kwesihlungi, kuzodala ukulimala kokukhathala kwento futhi kwakha imifantu yokukhathala. Ngakho-ke, isihlungi esakhiweni sokuqinisekisa ukuthi isici sokuhlunga sinokumelana okwanele kokukhathala, ekukhethweni kwezinto zokuhlunga kufanele zihlolwe (bheka i-ISO 3724).
