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.

Ungayilungisa kanjani ingcindezi ye-hydraulic relief valve

Khulula zonke izikulufu ze-valve yokukhulula, okokusebenza kuyagijima, qinisa kancane izikulufu, bheka igeji yokucindezela, bese umisa ngemva kwama-mpa ambalwa wokucindezela, vumela okokusebenza kugijime ngokwezibalo ngaphansi kwalokhu kucindezela imizuzu embalwa, bese uphinda. inqubo yokukhuphula nokusebenza kuze kube yilapho ingcindezi ebekiwe ilungiswa.

Isiteshi ngasinye se-hydraulic oil pump outlet sizoba ne-valve echichimayo, ngezinye izikhathi ngesizathu esithile, ukucindezela kokuphuma kwepompo kungase kube kukhulu kunokucindezela okudingekayo ohlelweni, kulokhu udinga i-valve yokuchichima ukuze ususe ukucindezela ngokweqile, amafutha abuyele emuva ithangi.
