I-Excavator khetha i-valve ye-hydraulic Safety valve 14543998 i-valve yesibili yokusiza

1.Isakhiwo esiphelele se-hydraulic excavator egcwele

Ama-hydraulic excavators ngokuvamile asebenzisa i-double pump circuit power variable power hydraulic system, iningi lazo esebenzisa isilawuli samandla esingashintshi ukulawula amaphampu adonsa amanzi amabili, futhi zonke izindlela zokusebenza zihlukaniswe ngamaqembu amabili (bheka imephu engezansi)
I-valve yokusebenza komshini wezandla noma i-valve yokusebenza yokulawula uhlelo lokushayela ukuze kuqedelwe umsebenzi.Ngaphezu kwalokho, kunduku yebhakede, ibhakede, ukusebenza kwe-boom, ukuze kuthuthukiswe isivinini samaphampu amabili ahlanganisiwe.
Thola futhi ususe amaphutha ajwayelekile

2. Amaphutha Ewonke

Ukuhluleka komshini wonke kubangelwa ukwehluleka kwengxenye evamile, ngalesi sikhathi kufanele kugxile ekuhloleni inani lamafutha ku-tank ye-hydraulic, isihlungi sokudonsa amafutha, ipayipi yokudonsa amafutha iphukile;Kuma-excavators asebenza nge-servo, ingcindezi yomshayeli ayanele
Izokwenza ukuthi ukusebenza kuhluleke, ngakho-ke isifunda samafutha omshayeli (ipompo yomshayeli, isici sokuhlunga, i-valve yokukhulula, ipayipi likawoyela, njll.) kufanele ihlolwe;Uma wonke umshini ungenaso isenzo futhi i-excavator ingenawo umuzwa womthwalo, ukuxhumana kwamandla phakathi kwepompo yamafutha nenjini kufanele kuhlolwe.
Izingxenye, njengama-splines, amagiya, njll.;Uma isenzo sihamba kancane, hlola uhlelo lokulungiswa kwe-servo lwephampu kawoyela.
3.Lapho izenzo eziningana ezilawulwa yiqembu lama-valve okulawula zingajwayelekile ngesikhathi esifanayo, alikho iphutha engxenyeni yomphakathi yamaqembu amabili wezinhlelo, futhi iphuzu lephutha liyingxenye yomphakathi yalezi zenzo.

1) I-valve yokusiza enkulu inephutha.
Iningi lama-valve okusiza abakhulu abavubukuli besimanje basebenzisa ama-valve okusiza umshayeli.Uma ukucindezela kwe-valve yokusiza kungalungiswa ngendlela engafanele, i-spool ayivaliwe ngokuqinile, futhi intwasahlobo iphukile, ukucindezela kwesistimu yonke kuphansi futhi ukugeleza kuncane.
Ukutholwa kokucindezela nokugudluzwa kwengxenye kungasetshenziswa njengezindlela zokuxilonga.
2) I-subsystem hydraulic pump regulating mechanism.
Abanye abembayo basebenzisa isistimu yokulawula ukuguquguquka kwamandla njalo, futhi iphampu ngayinye eguquguqukayo ilawulwa isilawuli sayo samandla esingaguquki..
Uma indlela yokulawula yehluleka, njengokuthi i-valve core ibambekile futhi ukuguga kubucayi, ingcindezi yokukhipha uwoyela wephampu kawoyela ayihambisani nomthetho wamandla ongashintshi, okuholela esenzweni esibuthakathaka nesihamba kancane.
