I-valve yebhalansi ye-Hydraulic Excavator i-hydraulic cylinder valve core NFCD-LFN

I-valve yokukhulula izindlela ezivamile zokuxazulula izinkinga

I-1) I-port yokukhipha i-valve yokusiza umshayeli ivinjiwe futhi ayivinjiwe, futhi uwoyela olawulayo awunawo ukucindezela, ngakho-ke uhlelo alunayo ingcindezi, futhi imbobo yokukhipha kufanele ivalwe ngokuqinile;

I-2) Isifunda samafutha esilawuli kude esixhunywe imbobo yesilawuli kude se-valve yokusiza sivulwa ukuze kulawulwe ukubuyisela uwoyela ethangini, ngakho-ke akukho ngcindezi ohlelweni.I-remote control oil circuit kufanele ihlolwe futhi i-oil circuit of the control oil return to the tank kufanele ivalwe;

I-3) Imbobo emanzi ye-valve yokusiza umshayeli ivinjiwe, okuholela ekungabini kwengcindezi ohlelweni.Umgodi wokudambisa kufanele uhlanzwe futhi kufakwe amafutha esikhundleni;

4) I-valve yekhoni elahlekile noma ibhola lensimbi noma isiphethu esilawula ukucindezela kufanele kushintshwe ngesikhathi;

5) Ivalvu evuzayo ibhajwe endaweni evuleke ngokugcwele ngokungcola, futhi kufanele ihlanzwe ngesikhathi;

6) Iphampu ye-hydraulic ayikho ingcindezi, kufanele ibhekane nokuhluleka kwepompo ye-hydraulic;

7) Izingxenye zesistimu noma ukulimala kwamapayipi kanye nenani elikhulu lokuvuza kukawoyela, kufanele kubhekwe ngesikhathi ukuze kulungiswe noma kushintshwe.

I-3, ingcindezi yesistimu inkulu kakhulu, ukulungiswa akusebenzi, kufanele kuthathe izinyathelo ezihambisanayo ngokuya ngezizathu ezilandelayo:

I-1) Isifunda samafutha okulawula kusukela ku-valve eyinhloko kuya ku-valve yomshayeli ivinjiwe, i-valve yomshayeli ayilawuli ukucindezela kwamafutha, hlola isifunda samafutha ukuze sixhumeke;

I-2) Imbobo yokukhipha uwoyela yangaphakathi ye-valve yomshayeli ivinjwe ukungcola, futhi i-valve yomshayeli ayikwazi ukulawula ukucindezela.Imbobo yokukhishwa kwamafutha yangaphakathi ye-valve yomshayeli kufanele ihlanzwe;

3) Ukugqoka kwembobo emanzi kukhulu kakhulu, ibhalansi yokucindezela kawoyela emikhawulweni yomibili ye-spool enkulu, i-valve yesilayidi ayikwazi ukuvulwa, kufanele icindezelwe eshidini lensimbi engagqwali njengembobo yokumanzisa noma ucingo lwensimbi oluthambile olufakiwe. emgodini, vimba ingxenye yomgodi wokudambisa;

4) Ukungcola kwamafutha, i-valve yesilayidi inamathele endaweni evaliwe.
