I-hydraulic balance valve Excavator hydraulic cylinder spool COHA-XFN

Umsebenzi oyinhloko we-valve yokusiza

Umphumela wokuchichima kwengcindezi eqhubekayo: Kusistimu yokulawula i-quantitative pump throttling, iphampu yobuningi inikeza izinga lokugeleza njalo. Lapho ingcindezi yesistimu ikhuphuka, isidingo sokugeleza sizokwehla. Ngalesi sikhathi, i-valve yokusiza ivuliwe, ukuze ukugeleza okweqile kugeleze kubuyele ku-tank, ukuqinisekisa ukuthi i-valve yokusiza i-inlet pressure, okungukuthi, ukucindezela kokuphuma kwepompo kuhlala njalo (i-valve port ivame ukuvulwa ngokushintshashintsha kwengcindezi) .

Umphumela wokuqiniswa kwengcindezi: I-valve yokusiza ixhunywe ochungechungeni kumjikelezo kawoyela obuyayo, i-valve yokusiza ikhiqiza ukucindezela emuva, futhi ukuzinza kwezingxenye ezihambayo kuyanda.

Umsebenzi wokukhipha uhlelo: imbobo yesilawuli kude yevalvu yokukhulula ixhunywe ku-solenoid valve ngokugeleza okuncane okuchichimayo. Uma i-electromagnetic inikwa amandla, imbobo yesilawuli kude sevalvu yokukhulula idlula ethangini likaphethiloli, futhi iphampu ye-hydraulic iyehliswa ngalesi sikhathi. I-valve yokukhulula manje isisetshenziswa njenge-valve yokukhipha.

Ukuvikela ukuphepha: Uma uhlelo lusebenza ngokujwayelekile, i-valve ivaliwe. Kuphela lapho umthwalo udlula umkhawulo oshiwo (ingcindezi yesistimu idlula ingcindezi ebekiwe), ukuchichima kuvulwa ukuze kuvikelwe ukulayisha ngokweqile, ukuze ukucindezela kwesistimu kungasakhushulwa (ngokuvamile ukucindezela okuhleliwe kwe-valve yokusiza ku-10% kuya ku-20% ngaphezu kokucindezela okukhulu kokusebenza kwesistimu).

Izicelo ezisebenzayo ngokuvamile: njenge-valve yokuthula, njengesilawuli sokucindezela okude, njenge-valve yokulawula i-multistage ephezulu nephansi, njenge-valve yokulandelana, esetshenziselwa ukukhiqiza ukucindezela emuva (intambo kumjikelezo kawoyela wokubuya).
