I-hydraulic balance valve Excavator I-hydraulic cylinder valve core CBBB-LHN

Ama-valve alinganiselayo alungisa amapharamitha we-hydraulic noma amandla ngamasignali ereferensi kagesi. Umgomo oyisisekelo wevalvu yokulingana: isignali yereferensi ehambisanayo ikhiqiza ukumunca kazibuthe kagesi okuhambisanayo, futhi ukumunca kazibuthe kagesi ku-spool ebuyiswa entwasahlobo, kuqhuba ukunyakaza kwe-spool, ukuze kuzuzwe ukulungiswa kwepharamitha ye-hydraulic edingekayo. I-valve yohlobo lwe-DLHZO iyi-valve esebenza kahle ye-servo proportional, ukusebenza okuqondile, ukwakhiwa komkhono we-valve, enenzwa ye-LVDT yendawo, ngokusho kwesignali kagesi yokufaka ukunikeza ukulawulwa kokuqondisa nokulawula ukugeleza ngaphandle kwesinxephezelo sengcindezi, ukwakhiwa komkhono we-valve, ukusebenza okuqondile, nenzwa yendawo. ,IS4401 ejwayelekile,06 ububanzi kanye 10 ububanzi.

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) . 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). Njenge-valve yokuthula, njengesilawuli sokucindezela okude, njenge-valve yokulawula i-multistage ephezulu nephansi, njenge-valve yokulandelana, esetshenziselwa ukukhiqiza ingcindezi yangemuva (intambo kumjikelezo wamafutha obuyayo).
