I-Excavator Accessories SK200-5 Ukulawula Ukulawula Ukuphepha I-Valve YN22v00002F1

Ekwenziweni kokwakhiwa kwansuku zonke, ukumba umgodi kuvame ukusungulwa kwemishini yokwakha, okusetshenziswa kabanzi ekumbeni kweSisekelo sezakhiwo zezindlu nokuhlanza ngemuva kokuphothula, ukwakhiwa kwamapayipi asemanzini, nezinzuzo zokwakhiwa okuguquguqukayo nokusebenza kahle. I-Excavator ngokuvamile yakhiwa ngocingo olusebenzayo, idivaysi ejikelezayo, i-cab, idivaysi yokuhamba kanye nohlelo lokulawula lwe-hydraulic, olungenakugwenywa ohlelweni lwe-hydraulic ukuze basebenzise i-valve ye-hydraulic ikakhulukazi badlala indima yokugcwala kokucindezela nokuphepha. Njengamanje, i-valve yokusiza esetshenzisiwe ku-Valive Sukuma i-valve, njengoba kukhonjisiwe kuMfanekiso 1 nangomkhono we-Valve Sleeve 3, i-Pilot Valve Sleeve inikezwe izimbobo, futhi i-Pilot Valve Sleeve ihlinzekwa nge-calve calve core cavity ngokusebenzisa Umgodi wokuphakanyiswa kwekhanda eliphakamisayo futhi wenza e-Pilot Valve Core. Lapho ingcindezi yesistimu ingaphansi kwengcindezi yokuvula ye-pleot yokuqala spool, i-Pilot Valve isesimweni esivaliwe, kanye nezingcindezi zangaphakathi nezangaphandle ze-spool eyinhloko ziyalingana. Ngenxa umehluko ezindaweni zangaphakathi nangaphandle, i-spool eyinhloko ihlala ivaliwe ngaphansi kwesenzo sokucindezela okuwuketshezi; Lapho ukucindezela kohlelo kukhulu kunokucindezela kokuvulwa kwe-Pilot Valve Spool, i-Pilot Valve Spool idonswa uwoyela wokucindezela, futhi uwoyela wokucindezela ugeleza ubuyela ethangini ngomgodi we-Pilot Valve Sleeve kanye ne-Valve Sleeve Hole. Ngalesi sikhathi, ukwehla kwengcindezi kukhiqizwa lapho uketshezi lugeleza emgodini odonsayo wekhanda lokuphakamisa, ukuze ingcindezi yangaphakathi ye-master valve spool iyovulwa, futhi uwoyela we-hydraulic ugeleza ubuyela ethangini eliphambili le-valve sleeve hole. Lapho umcindezeli wesistimu ehla ngaphansi kwengcindezi yokuvula ye-Pilot Spool, i-Pilot Spool evala, kwathi lapho umehluko wengcindezi phakathi kwangaphakathi nangaphandle kwe-spool eyinhloko mncane, ukuvulwa kuvaliwe ngaphansi kwesenzo se-reset ntwasahlobo. Kodwa-ke, ekusetshenzisweni kwangempela, kutholakala ukuthi lapho kusetshenziswa i-valve engenhla, i-Pilot Valve Core idinga ukuvula nokuvala njalo, futhi ukuvala ukusebenza kwe-Pilot Valve Sleeve Hole ku-Pilot Valve Sleeve Isigaxa esibalulekile kakhulu. Ukuze uqinisekise ukuqina kokusebenza kwe-valve yokusiza, indawo ye-Pilot Valve Sleeve ivame ukudinga ukunemba okuphezulu kwemishini. Umgodi we-Pilot Valve Sleeve mude, umkhono we-Pilot Valve endaweni yokucubungula nokuhlola kunzima ngokwengeziwe, ukunemba kwe-valve esebenza kahle akunakuqinisekiswa kakhulu, ngaphezu kwalokho, umkhono we-valve omkhulu phakathi kwe-cooaxiality ancishiswe kakhulu ku-Pilot Valve Sleeve Sleeve srew isikhundla ukuze aqinisekise, ngoba i-Valve Valve Umkhono mude, ukuphambuka okuncane kokuma kwentambo kuzothinta futhi ukulingana kwe-spool eyinhloko kanye nomkhono we-valve, okuholela ekubekeni kahle nokuvuza okumpofu.
