Izingxenye ze-Excavator PC300-5 PC400-5 Lawula i-valve eyinhloko 709-90-52203 i-valve yokusiza

I-valve yokusiza ye-excavator ihlanganisa ikhanda eliphakamisayo 11, i-spool ye-valve eyinhloko 12, umkhono we-valve oyinhloko 13, i-spool ye-valve yokushayela engu-14, ingcindezi elawula intwasahlobo 15 kanye nomkhono wevalve yomshayeli. I-spool ye-valve eyinhloko i-12 ihlelwe ngaphakathi komkhono we-valve oyinhloko 13, i-spool ye-valve eyinhloko 12 ihlinzekwa ngekhanda eliphakamisayo 11 nomkhono we-valve yomshayeli, futhi umkhono we-valve womshayeli uhlinzekwa nge-spool ye-valve yomshayeli 14. Umkhono we-valve yomshayeli Isakhiwo se-valve esiyizigaba ezimbili, esakhiwe ngomzimba we-valve engu-16 kanye nesembozo se-valve engu-17, umzimba we-valve kude nesiphetho sesembozo se-valve uhlelwe kumongo we-valve oyinhloko, umzimba we-valve eduze nokuphela kwesembozo se-valve uvele wenza u-boss 18, nomphathi kumkhono wevalvu oyinhloko unikezwe i-groove, umkhawulo wokubopha okubili wakha isakhiwo somkhawulo. Uma isakhiwo sisetshenziswa, ngoba umkhono wevalvu wokushayela uhlukaniswe izingxenye ezimbili zomzimba we-valve engu-16 kanye nesembozo se-valve engu-17, umkhono omkhulu we-valve 13 unikezwa umsele, umzimba we-valve uhlinzekwa ngomphathi 18, osetshenziselwa lungisa umzimba we-valve 16 i-radial ne-axial, umgogodla we-valve eyinhloko kanye nekhanda eliphakamisayo kuhlelwa ngokulandelana ngaphakathi komkhono we-valve oyinhloko, futhi umzimba we-valve ufakwa kuqala emgodini oyinhloko we-valve ngesikhathi sokufakwa. Thembela kuma-grooves kumkhono we-valve oyinhloko ukuze ukhawule umzimba we-valve nge-axially kanye ne-radially, bese ugoqa isivalo se-valve kumkhono we-valve oyinhloko bese ucindezela umzimba we-valve ukulungisa umzimba we-valve, bese i-valve yokukhulula ingasetshenziswa ngokujwayelekile.

1. I-valve yokusiza i-excavator ihlanganisa ikhanda eliphakamisayo (11), i-valve spool (12), umkhono we-valve oyinhloko (13), i-spool ye-valve yokushayela (14), isiphethu esilawula ukucindezela (15) nomkhono we-valve wokushayela. . I-spool ye-valve eyinhloko (12) ihlelwe ngaphakathi komkhono we-valve oyinhloko (13), futhi i-spool ye-valve eyinhloko (12) ihlinzekwa ngekhanda eliphakamisayo (11) kanye nomkhono wevalve yomshayeli. Umkhono we-valve wokushayela uhlinzekwa onomgogodla we-valve yokushayela (14), obonakala ngokuthi umkhono we-valve wokushayela uyisakhiwo esinezigaba ezimbili, esakhiwe ngomzimba we-valve (16) kanye nesembozo se-valve (17), i-valve. umzimba (16) kude nesembozo sevalvu (17) isiphetho esisodwa sihlelwe kumongo wevalvu eyinhloko (12), Umzimba we-valve (16) eduze kwesembozo sevalvu (17) - isiphetho sixhumeke ngaphakathi ngomkhono wevalvu omkhulu (13) ) ngesakhiwo esikhawulelayo.
2. Ngokwesimangalo 1, i-valve yokusiza i-excavator ibonakala ngokuthi umzimba we-valve (16) eduze kwesembozo se-valve (17) ugcina ungobasi (18), futhi ubasi unikezwe umsele ngaphakathi. umkhono wevalvu oyinhloko (13), kanye nemikhawulo emibili yokubopha yakha isakhiwo somkhawulo.
Imodeli yensiza idalula i-valve yokusiza umamba, okuhlanganisa ikhanda eliphakamisayo, umgogodla we-valve oyinhloko, umkhono we-valve oyinhloko, i-valve core, isiphethu esilawula ukucindezela kanye nomkhono we-valve yomshayeli, umgogodla oyinhloko we-valve uhlelwe ngaphakathi kwe-main. Umkhono we-valve, umgogodla we-valve oyinhloko uhlinzekwa ngekhanda eliphakamisayo kanye nomkhono we-valve yomshayeli, umkhono we-valve wokushayela uhlinzekwa onomgogodla we-valve yomshayeli, obonakala ngokuthi umkhono we-valve wokushayela uyisakhiwo esihlukaniswe izigaba ezimbili. Yakhiwe ngomzimba we-valve nesembozo se-valve, umzimba we-valve kude nomkhawulo wekhava ye-valve uhlelwe kumongo we-valve oyinhloko, umzimba we-valve eduze nesiphetho sesembozo se-valve ngokusebenzisa isakhiwo somkhawulo kanye nomkhono we-valve oyinhloko uxhumano lwangaphakathi. Imodeli yensiza ihlukanisa umkhono we-valve womshayeli ube umzimba we-valve kanye nesembozo se-valve, ngaleyo ndlela yehlise ubude bomgodi ongaphakathi womkhono we-valve yomshayeli, ithuthukise ukunemba kokucubungula kwengxenye yokuxhumana phakathi komkhono we-valve yomshayeli kanye nomongo we-valve yomshayeli, futhi ngaleyo ndlela kuthuthukiswe ukuzinza kwe-valve yokusiza.
