Amalungu e-excavator PC300-5 PC400-5 Lawula ivalve engundoqo 709-90-52203 ivalve yokukhulula

Ivalve yokukhulula i-excavator iquka i-11 ephakamisa intloko, i-spool yevalve engundoqo 12, umkhono wevalve engundoqo 13, i-valufa ye-pilot spool 14, i-presso elawula i-spring 15 kunye nomkhono wevalve yokulinga. I-spool yevalve engundoqo i-12 icwangciswe ngaphakathi komkhono wevalve engundoqo we-13, i-spool yevalve engundoqo i-12 ibonelelwe ngentloko ephakamisayo 11 kunye nomkhono wevalve yomqhubi wenqwelo-moya, kunye nomkhono wevalve yokulinga unikwe umkhono wevalve yokulinga 14. Umkhono wevalve yokulinga lulwakhiwo olunamanqanaba amabini, elenziwe ngumzimba wevalve 16 kunye nesigqubuthelo sevalve 17, umzimba wevalve kude nesiphelo sesivalo sevalve ucwangciswe kumbindi wevalve engundoqo, umzimba wevalve kufutshane nesiphelo sesivalo sevalve ujike wenza ivalve. uboss 18, kunye nomphathi kumkhono wevalve engundoqo unikwe igroove, umda wokugoba kabini ubandakanya ubume bomda. Xa ulwakhiwo lusetyenziswa, kuba umkhono wevalve yokulinga wahlulwe ube ngamacandelo amabini omzimba wevalve 16 kunye nesigqubuthelo sevalve 17, umkhono omkhulu wevalve 13 unikwe umjelo, umzimba wevalve unikwe umphathi 18, osetyenziswa lungisa umzimba wevalve i-16 ye-radial kunye ne-axial, umbindi wevalve engundoqo kunye nentloko yokuphakamisa zicwangciswe ngokujikelana ngaphakathi komkhono wevalve engundoqo, kwaye umzimba wevalvu ufakwa kuqala kumngxuma ongundoqo wevalve ngexesha lofakelo. Thembela kwiigrooves kumkhono wevalvu engundoqo ukunciphisa umzimba wevalvu nge-axially kunye neradially, kwaye emva koko ujije isivalo sevalvu kumkhono wevalvu engundoqo kwaye ucinezele umzimba wevalvu ukulungisa umzimba wevalvu, kwaye ivelufa yokukhulula ingasetyenziswa ngokuqhelekileyo.

1. Ivalve yokukhulula i-excavator inentloko ephakamisayo (11), i-valve spool (12), umkhono wevalve engundoqo (13), i-valve spool yokulingwa (14), isipringi esilawula uxinzelelo (15) kunye nomkhono wevalve olingwayo. . I-spool yevalve engundoqo (12) icwangciswe ngaphakathi komkhono wevalve engundoqo (13), kwaye i-spool yevalve engundoqo (12) inikwe intloko ephakamisayo (11) kunye nomkhono wevalve yokulinga. Umkhono wevalve yokulingwa unikwe umbindi wevalve (14), ophawulwa ngokuba umkhono wevalve wolingo ukwinqanaba ezibini, elenziwe ngumzimba wevalve (16) kunye nesivalo (17), isivalo. Umzimba (16) kude nesigqubuthelo sevalve (17) isiphelo esinye sicwangciswe kumbindi wevalve (12), Umzimba wevalve (16) kufutshane nesivalo sevalve (17) - isiphelo sidityaniswe ngaphakathi kunye nomkhono wevalve (13) ) ngolwakhiwo olusikelwe umda.
2. Ngokwebango 1, ivalve yokukhulula i-excavator ibonakaliswe ngokuba umzimba wevalve (16) kufuphi nesivalo sevalvu (17) ujika wenze umphathi (18), kwaye umphathi unikwe umsele ngaphakathi. umkhono wevalve engundoqo (13), kunye nemida ebambeneyo emibini zenza umda wesakhiwo.
Imodeli esetyenziswayo ityhila ivalve yokukhulula i-excavator, kubandakanywa intloko ephakamisayo, i-valve core, i-valve engundoqo, i-valve core, i-valve core, i-spring elawula uxinzelelo kunye ne-sleeve yevalve yomqhubi, i-valve core ihlelwe ngaphakathi kweyona nto iphambili. Umkhono wevalve, umbindi wevalve ongundoqo unikwe intloko ephakamisayo kunye nomkhono wevalve yokulinga, umkhono wevalve yokulinga unikezelwe ngondoqo wevalve, ophawulwa ngokuba umkhono wevalve yokulinga sisakhiwo esinamanqanaba amabini. Idityaniswe ngumzimba wevalve kunye nesigqubuthelo sevalvu, umzimba wevalve kude nesiphelo sesivalo sevalve ucwangciswe kumbindi wevalve engundoqo, umzimba wevalve kufutshane nesiphelo sesivalo sevalvu ngesakhiwo somda kunye nomkhono wevalve ongundoqo uqhagamshelo lwangaphakathi. Imodeli esebenzayo yahlula umkhono wevalve yokulinga ibe ngumzimba wevalvu kunye nesigqubuthelo sevalvu, ngaloo ndlela inciphisa ubude bomngxuma ongaphakathi womkhono wevalufa yokulinga, ukuphucula ukuchaneka kwecandelo loqhagamshelwano phakathi komkhono wevalve yokulinga kunye nesiseko sevalve yomqhubi, kunye nokuphucula ukuzinza kwevalve yokukhulula.
