I-hydraulic balance valve Excavator i-hydraulic cylinder valve core CBGA-LBN

Isimiso sokusebenza se-valve yokusiza

I-valve yokukhulula iwuhlobo lwe-valve yokulawula ingcindezi kawoyela, edlala ngokuyinhloko indima yokuchichima kwengcindezi, ukulawulwa kwengcindezi, ukuhlehla kwesistimu nokuvikelwa kokuphepha emishinini yokucindezela uwoyela.

Isimiso se-valve yokukhulula: Kuhlelo lokulawula i-quantitative pump throttling, iphampu yobuningi inikeza izinga lokugeleza njalo, futhi lapho ukucindezela kwesistimu kuncishisiwe, isidingo sokugeleza sizoncishiswa. Ngalesi sikhathi, i-valve yokusiza ivula i-valve elawula ukucindezela kanye nokunciphisa ukwenza ukugeleza okudlulele kuchichime emuva ethangini futhi kuqinisekiswe ukucindezela kokungena kwe-valve yokusiza.

Kusistimu yokulawula i-pump throttling, ipompo ehleliwe inikeza ukugeleza okuqhubekayo. Lapho ukucindezela kwesistimu kuncishisiwe, isidingo sokugeleza sizoncishiswa. Ngalesi sikhathi, i-valve yokusiza ivuliwe, ukuze ukugeleza okudlulele kugeleze ku-tank pressure regulator kanye ne-valve yokunciphisa ingcindezi, ukuqinisekisa ukuthi i-valve yokusiza i-inlet pressure, okungukuthi, ingcindezi yokuphuma kwepompo ihlala njalo (imbobo ye-valve kuvame ukuvulwa ngokuguquguquka kwengcindezi).

Umehluko phakathi kwe-valve yokusiza kanye ne-valve yokunciphisa ingcindezi

I-valve yokusiza iwukugwema ukushesha kwesistimu futhi uqinisekise ukuphepha. I-valve yokunciphisa ingcindezi iwukwandisa ingcindezi yesistimu ngaphansi kwesisekelo sokuqinisekisa ukuthi uhlelo alukho isigaba.

I-1, i-valve yokunciphisa ingcindezi isetshenziselwa kakhulu ukunciphisa ukucindezela komugqa wegatsha wesistimu yokucindezela uwoyela, ukuze ukucindezela kwegatsha kube phansi futhi kuzinzile kunokucindezela okukhulu kwamafutha, ebangeni lokusetha ingcindezi, i-valve yokunciphisa ingcindezi iphinde icime njenge-valve yokusiza. Futhi ngokuncipha kwengcindezi yesistimu, lapho ingcindezi ebekwe yi-valve yokunciphisa ingcindezi ifinyelelwa, kuvulwa i-valve yokunciphisa ingcindezi, futhi ingxenye yamafutha izobuyela ethangini (ngalo mzuzu, kukhona ukucindezela okuthile amafutha abuyele ethangini, izinga lokushisa lamanzi ethangi lizokhuphuka), ukucindezela kwe-hydraulic yaleli gatsha ngeke kukhuphuke. Idlala indima yokunciphisa ingcindezi kanye nokuzinzisa ingcindezi kulo mzila! I-valve yokusiza ihlukile, futhi ifakwe ekuphumeni kwepompo ukuze kuqinisekiswe ukuthi ukucindezela okuphelele kwesistimu kuzinzile futhi akucindezeli ngokweqile. Ngakho-ke, unendima yokuphepha, ukulawulwa kwengcindezi, ukulawulwa kwengcindezi nokunye!

I-2, i-valve yokusiza ngokuvamile ihambisana ohlelweni lomgwaqo wezintaba ukuze idlale indima yokulawula ingcindezi, ukulawulwa kwengcindezi nokunciphisa ingcindezi, futhi i-valve yokunciphisa ingcindezi ngokuvamile iwuchungechunge emgwaqeni ukuze idlale indima yokunciphisa ingcindezi futhi ingcindezi ukulondolozwa komgwaqo!

3, i-valve yokusiza ngokuvamile ivaliwe, kodwa futhi lapho isenzo sokucindezela ngokweqile kwesistimu; I-valve yokunciphisa ingcindezi ivulekile futhi icindezela ngesiteshi esincane.

I-4, indima ye-valve yokusiza ukulawula ingcindezi, ukuchichima, ukuvikela ukugcwala. I-valve yokunciphisa ingcindezi inciphisa ukucindezela, futhi ingcindezi engxenyeni ethile yesistimu yokucindezela uwoyela iyancipha. Ukusetshenziswa okuhlukile. Ngakho-ke, ayikwazi ukushintshwa.
