Izesekeli ze-Excavator SK200-5 excavator main control valve security YN22V00002F1

Ekukhiqizeni ukwakhiwa kwansuku zonke, i-excavator ingumshini wokwakha osetshenziswa kakhulu, osetshenziswa kabanzi ekumbiweni kwesisekelo sezakhiwo zezindlu nokuhlanza ngemuva kokuqedwa, ukubekwa kwamapayipi asemadolobheni, ukwakhiwa kwendawo yokongiwa kwamanzi epulazini kanye nezinye izikhathi, ngezinzuzo zokwakha okuguquguqukayo kanye nokuphakama okuphezulu. ukusebenza kahle. I-Excavator ngokuvamile yakhiwa idivayisi esebenzayo, idivayisi ejikelezayo, i-cab, idivayisi yokuhamba kanye nesistimu yokulawula i-hydraulic, engenakugwema ohlelweni lokulawula olusebenzisa amanzi ukuze kusetshenziswe i-valve yokusiza, i-valve yokusiza ohlelweni lwe-hydraulic ikakhulukazi idlala indima yokuchichima kwengcindezi eqhubekayo futhi ukuvikelwa kokuphepha. Njengamanje, i-valve yokusiza esetshenziswa kumcwebi iyi-valve yokusiza umshayeli, njengoba kukhonjisiwe kuMfanekiso 1 kanye noMfanekiso 2. Ikakhulukazi yakhiwe ngokuphakamisa ikhanda 1, umgogodla oyinhloko we-valve 2, umkhono we-valve oyinhloko 3, umgogodla we-valve 4, intwasahlobo elawula ukucindezela. 5 kanye nomkhono wevalve yomshayeli 6. Ikhanda eliphakamisayo, umkhono wevalve oyinhloko nomkhono wevalve yomshayeli kuhlinzekwa ngezimbobo, futhi uwoyela wokucindezela ungena emgodini oyinhloko we-valve ngembobo emanzi yekhanda eliphakamisayo bese usebenza kumongo wevalvu yomshayeli. Uma ingcindezi yesistimu ingaphansi kokucindezela kokuvula kwe-spool yokuqala yomshayeli, i-valve yomshayeli isesimweni esivaliwe, futhi izingcindezi zangaphakathi nangaphandle ze-spool enkulu zilingana. Ngenxa yomehluko ezindaweni zangaphakathi nangaphandle, i-spool eyinhloko ihlala ivaliwe ngaphansi kwesenzo sokucindezela kwamanzi; Uma ingcindezi yesistimu inkulu kunomfutho wokuvula we-spool ye-valve yokushayela, i-spool ye-valve yomshayeli idudulwa uwoyela wokucindezela, futhi uwoyela wokucindezela ugeleza ubuyele ethangini ngembobo yomkhono wevalvu yomshayeli kanye nembobo yomkhono wevalvu eyinhloko. Ngalesi sikhathi, ukwehla kwengcindezi kukhiqizwa lapho uketshezi lugeleza emgodini omanzi wekhanda lokuphakamisa, ukuze ukucindezela kwangaphakathi kwe-spool ye-valve enkulu kube kukhulu kunokucindezela kwegumbi langaphandle, eliphusha i-spool ye-valve enkulu ukuba ivule, futhi uwoyela we-hydraulic ugeleza ubuyela ethangini ngembobo yomkhono wevalvu eyinhloko. Lapho ingcindezi yesistimu yehla ibe ngaphansi kokucindezela kokuvula kwe-spool yomshayeli, i-spool yomshayeli iyavala, futhi lapho umehluko wengcindezi phakathi kwangaphakathi nangaphandle kwe-spool eyinhloko mncane, ukuvuleka kuvaliwe ngaphansi kwesenzo sokusetha kabusha kwentwasahlobo. Kodwa-ke, ekusetshenzisweni kwangempela, kutholakala ukuthi lapho kusetshenziswa i-valve yokusiza engenhla, umgogodla we-valve wokushayela udinga ukuvula nokuvala njalo, futhi ukusebenza kokuvula nokuvala kwe-valve yomshayeli kunquma ukusebenza kwe-valve yokusiza, ngakho ingxenye wembobo yomkhono we-valve yomshayeli oxhumene nekhoni ewumgogodla we-valve ibaluleke kakhulu. Ukuze kuqinisekiswe ukuzinza kokusebenza kwe-valve yokusiza, indawo yomkhono we-valve yomshayeli ngokuvamile idinga ukunemba okuphezulu komshini. Imbobo ye-valve yomshayeli ide, umkhono we-valve womshayeli endaweni yokucubungula nokuhlola kunzima kakhulu, ukunemba kokucubungula kunzima ukuqinisekisa, okuholela ekusebenzeni kwe-valve yomshayeli akukwazi ukuqinisekiswa ngempumelelo, ukuzinza kwe-valve yokusiza kukhulu kakhulu. okuthintekayo, ngaphezu kwalokho, umgogodla oyinhloko we-valve kanye nomkhono we-valve oyinhloko phakathi kwe-coaxiality ikakhulukazi kuncike ekumiseni kwesikulufu se-valve yomshayeli ukuze kuqinisekiswe, ngoba umkhono we-valve womshayeli mude, Ukuchezuka okuncane kokuma kwentambo kuzophinde kuthinte ukulingana i-spool enkulu kanye nomkhono we-valve oyinhloko, okuholela ekuvaleni kahle nokuvuza.
