Izimpawu ze-Spool
I-pilot fluid supply
1, 4DWHG10
(1) Umshayeli wangaphakathi nomshayeli wangaphandle:Imbobo ye-“P” ene-M6 screw 3 iwumshayeli wangaphandle, ukuguqula ivalvu ibe umshayeli wangaphakathi, isikulufu esingu-3 esingu-M6 kufanele sikhishwe.
(2) Ukukhipha amanzi kwangaphakathi kanye nokukhipha amanzi angaphandle: Ukukhipha ibhawodi 1, ukufaka isikulufu se-M6 wukukhipha amanzi angaphandle, khipha isikulufu se-M6 isikulufu 2 siwukukhipha kwangaphakathi.
2, 4DWHG16
(1) Umshayeli wangaphakathi nomshayeli wangaphandle: Ukukhipha ikhava eseceleni, ukufaka iphinikhodi ukuze kuvunyelwe imbobo ethi “P” enendawo evulekile umshayeli wangaphakathi, ukuguqula iphinikhodi libe imbobo ethi “P” enendawo exhunyiwe kuwukudonsa amanzi ngaphandle.
(2) Ukukhipha amanzi kwangaphakathi nokukhipha amanzi angaphandle: Ukukhipha ibhawodi 1 nokufaka isikulufu esingu-M6 kuwukukhipha amanzi angaphandle, khulula isikulufu se-M6 isikulufu esingu-2 siwukukhipha kwangaphakathi.
I-pilot fluid supply
3, 4DWHG25
(1) Umshayeli wangaphakathi nomshayeli wangaphandle: Ukukhipha ikhava eseceleni, ukufaka isikulufu se-M6 ngumshayeli wangaphandle, ukukhulula isikulufu se-M6 ngumshayeli wangaphakathi.
(2) Ukukhipha amanzi kwangaphakathi nokukhipha amanzi angaphandle: Ukukhipha isikulufu esingu-M6 embobeni “T” phezulu kwevalvu eyinhloko kuwukukhipha kwangaphakathi, ukufaka isikulufu esingu-M6 kuwukukhipha amanzi ngaphandle.
4, 4DWHG32
1, Umshayeli wangaphakathi nomshayeli wangaphandle: Ukufaka i-M6 screw 1 “P” port phezulu kwevalvu eyinhloko umshayeli wangaphandle; ukususa isikulufu esingu-M6 kungumshayeli wangaphakathi.
2, Ukukhipha amanzi kwangaphakathi nokukhipha amanzi angaphandle: Ukukhipha isikulufu esingu-M6 embobeni ethi “T” phezulu kwevalvu eyinhloko kuwukudonsa kwangaphandle;ukufaka isikulufu esingu-M6 kuwukudonsa kwangaphakathi.
QAPHELA : 1.Imbobo ethi “X” ku-base plate kufanele ixhunywe uma i-pilot yangaphakathi.
2.Imbobo ethi “Y” ku-base plate kufanele ixhunywe uma kuphuma amanzi angaphakathi.
