Ifanele i-PC400-6 gun 723-90-61400 valve yokusiza

Iphi i-valve yokukhulula ye-excavator

Ngaphezu kwe-valve yokukhipha, umumo ofanayo. Okokuqala ubheka i-hydraulic pump ngenhla, uzobona ukuthi kunamapayipi amabili anosayizi ofanayo, azoba mkhulu kunamanye amapayipi, lawa mapayipi amabili aya kuvalvu yokusabalalisa, i-valve yokusabalalisa ngaphezu kwe-valve yokulawula ehambisanayo nalawa mapayipi amabili. i-valve yokusiza. I-valve yokusiza inomphumela wokuchichima kokucindezela okuqhubekayo: ohlelweni lokulawula i-quantitative pump throttling, ipompo yokulinganisa 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) .

Indima ye-valve yokusiza

Umphumela we-Spillover. I-throttle valve ingakwazi ukulungisa futhi ilinganise ukugeleza kwezinto ezisebenza ngaphansi kwamanzi lapho iphampu yobuningi ihlinzeka ngowoyela. Iqhaza lokuvikela ukuphepha. Vimbela izingozi ezibangelwa ukugcwala ngokweqile kwezinto zokusebenza ezisebenza ngaphansi komhlaba kanye namathuluzi omshini. Isetshenziswa njenge-valve yokukhipha. I-valve yokuphepha yomshayeli kanye nevalve ye-solenoid enezinhlangothi ezimbili zisetshenziswa ndawonye futhi zingasetshenziswa njengesistimu yokuthulula. Isilawuli kude namavalvu okulawula ingcindezi. Ukulawula isiteji esiningi nesiphansi. Isetshenziswa njenge-valve yokulandelana.

Uma i-valve yokusiza ye-excavator iphukile, izothinta isenzo, futhi ingcindezi kawoyela ayikwazi ukudluliselwa ekamelweni eliphezulu le-valve enkulu kanye negumbi langaphambili le-valve yokushayela, futhi i-valve yokushayela izolahlekelwa umphumela wayo wokulawula. ukucindezela kwe-valve eyinhloko; Ngenxa yokuthi akukho ukucindezela kwamafutha ekamelweni eliphezulu le-valve eyinhloko futhi amandla entwasahlobo mancane kakhulu, i-valve eyinhloko iba i-valve yokusiza esebenza ngokuqondile ngamandla amancane asentwasahlobo. Lapho ukucindezela kwekamelo lokungena kwamafutha liphansi kakhulu, i-valve eyinhloko izovula ukuchichima, futhi uhlelo ngeke lukwazi ukumisa ukucindezela.
