I-PC200-7 I-valve yokusiza i-Overload Excavator hydraulic izingxenye 723-40-91200

I-valve yokusiza ngokuvamile inezakhiwo ezimbili:

1, i-valve yokusiza esebenza ngokuqondile.

2. Ivalvu yokusiza esetshenziswa umshayeli.

Wonke aphezu kwevalve yokukhipha, umumo ofanayo. Okokuqala ubheka i-hydraulic pump ngenhla, uzobona ukuthi kunamapayipi amabili anobukhulu obufanayo, azoba mkhulu kunamanye amapayipi, lawa mapayipi amabili aya kuvalvu yokusabalalisa, kuvalvu yokusabalalisa kanye ne-valve yokulawula ehambisana nayo. amapayipi amabili i-valve enkulu 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).
