Indima ye-valve yokusiza

I-1, umphumela wokuchichima kwengcindezi eqhubekayo: ohlelweni lokulawula i-quantitative pump throttling, iphampu yobuningi inikeza ukugeleza okuqhubekayo. Lapho ukucindezela kwesistimu kuncishisiwe, isidingo sokugeleza sizoncishiswa. Kulo mzuzu, i-valve yokusiza ivuliwe, ukuze ukugeleza okudlulele kugeleze kubuyele ethangini, ukuqinisekisa ukuthi i-valve yokungena yokucindezela, okungukuthi, ingcindezi yokuphuma kwepompo ihlala njalo (imbobo ye-valve ivame ukuvulwa ngokushintshashintsha kwengcindezi) .

I-2, umphumela wokulawula ingcindezi: i-valve yokukhulula ixhunywe ngochungechunge epayipini lokubuya, i-valve yokukhulula yenza ukucindezela emuva, futhi izingxenye ezihambayo zithuthukisa ukuvuleka.

Isenzo sokuchema kwesistimu: imbobo yesilawuli kude sevalvu yokukhulula ixhunywe ku-solenoid valve ngokugeleza okuncane okuchichimayo. Uma inethiwekhi ye-electromagnetic inikwa amandla, imbobo yesilawuli kude sevalvu yokukhulula idlula ithangi likaphethiloli, futhi iphampu ye-hydraulic ihlehliswa okwamanje. I-valve yokusiza manje isetshenziswa njenge-valve ehlehlisayo.

I-3, ukuvikelwa kokuphepha: Uma uhlelo lusebenza ngokujwayelekile, i-valve yebhola ivaliwe. Kuphela lapho umthwalo udlula umkhawulo obekiwe (ukucindezela kwesistimu kudlula ukucindezela kokusetha), ukuchichima kuvuliwe ukuze kuvikelwe ukulahlekelwa kwesigaba, ukuze ukucindezela kwesistimu kungasakhushulwa (ngokuvamile, ukucindezela kokubeka kwe-valve yokusiza kungu-10% kuya I-20% ephakeme kunengcindezi ephezulu yokusebenza yesistimu).

I-4, isicelo esisebenzayo ngokuvamile: njenge-valve ehlehlisayo, njengesilawuli se-remote pressure, njenge-valve yokulawula i-multistage ephezulu nephansi, njenge-valve yokulandelana, efanelekile ukwakheka kwengcindezi yangemuva (intambo epayipini lokubuyisela).

I-valve yokusiza ngokuvamile inezakhiwo ezimbili: 1, i-valve yokusiza esebenza ngokuqondile. 2. Ivalvu yokusiza esetshenziswa umshayeli.

Izidingo eziyinhloko ze-valve yokusiza yilezi: ububanzi obukhulu bokulawulwa kwengcindezi, iphutha elincane lokulawula ingcindezi, i-oscillation encane yokucindezela, isenzo esibucayi, umthamo wokulahlekelwa kwesigaba esikhulu, nomsindo omncane.

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).
