Isenzeko sephutha: I-Xugong QY20B crane ijikeleza ngokushesha futhi kancane.
Incazelo yephutha: ngena esitimeleni bese ujikeleza ngokushesha ngenkathi uhamba kancane. Qaphela ukuthi izingcindezi ezinhlangothini zombili zehlukile ngesikhathi sokusebenza kwensimu.
Imbangela yokuhlaziywa kokwehluleka:
1: Isikulufa sokuma kwesiqu se-rotary valve sesikhashana sikhululekile.
2. I-valve yendlela eyodwa ngemuva kwe-rotary buffer valve ayivalwanga ngokuqinile, okuholela ekuvuza kwamafutha okucindezela ohlangothini olulodwa.
3. I-valve eshuttle ku-valve egcwele ngokweqile ye-rotary buffer valve ayivaliwe ngokuqinile, okuholela ekuvuza kukaphethiloli ohlangothini olulodwa.
Izinyathelo nezindlela zokuxazulula inkinga:
1: ulungise isiqu ukuma isikulufa esiqinile rotary sesikhashana valve.
2. Hlola i-valve yendlela eyodwa ngemuva kwe-roter buffer valve.
3. Ukulungisa i-shuttle valve ye-valve egcwele ngokweqile ye-valve ye-roter buffer.
Uma sikhuluma ngalokho, i-QY70KC yaneliseke kakhulu ngobude bengalo yayo engama-48m. Izigaba eziyisihlanu ze-boom main, i-single-plate boom head kanye ne-compact boom tail, ukusebenza kokuphakamisa kungu-9% ngaphambi kwemikhiqizo emisha yomkhakha yezinga elifanayo le-ton, kanye nokusebenza kwemvamisa ephezulu yokusebenza kwe-boom ephakathi nendawo ende futhi kugcwele ukufinyelela kungu-10% kuya ku-15%. Lokhu kwamvumela ukuthi abhekane ngokuthula nezimo ezahlukahlukene zobunjiniyela. Ukudubula okusheshayo, ukuqhuma okusheshayo, ukunyakaza okunamandla okuqinile, nokusebenza kahle okukhulu kungamlethela inani eliphakeme nembuyiselo ephezulu.
Mayelana nokusebenza kokuphakama, i-QY70KC nayo ivelele. Masithathe imodeli yakudala ye-XCMG ye-QY70K ukuqhathanisa. I-QY70KC ephakamisa i-jib (lapho inwetshwe ngokuphelele yaya kuma-48m) ingasetshenziswa endaweni ephakeme cishe ngama-degree angama-40. Ububanzi bungafika ku-36m kanti ukuphakama kuphakama kufika ku-31m. Kulesi simo, umthamo ophakeme kakhulu wokuphakamisa usengafinyelela kumathani ayi-1.6. I-QY70K endala inobude bokuphakamisa obukhulu obungu-25m nesisindo esiphakeme kakhulu samathani ayi-0.7 kuphela ku-boom egcwele (44.5m), i-counterweight egcwele (6t) no-36m ububanzi. Ngokuqhathanisa, ukusebenza okuphezulu kwe-QY70KC kuyaziveza.
I-QY70KC inezinto eziningi zokulwa nezinsika ezinde, okuyinzuzo kakhulu. Ubude bengalo bungafinyelela ku-48m. Uma kuqhathaniswa ne-QY70K endala (ubude bengalo 44.5m), ukuphakama okuphezulu kokuphakamisa kungaba cishe u-5m ohlukile ebangeni elifanayo! Ungalibukeli phansi leli gebe, kufanele uhlangane neminye imisebenzi ekhohlisayo, noma ungeke ukwazi ukuyithumela ngemitha elilodwa.
Mayelana nokusingatha ukusebenza, i-QY70K nayo iye yamukelwa ngazwi linye. I-QY70K isebenzisa uhlelo lwe-G-generation dual-variable pump + valve post-compensation load-sensing system, amaphampu amabili ahlukaniswe ngokuzenzakalela futhi ahlanganiselwe ukulawula, futhi ukusebenza kahle kuhola phambili embonini. Ngamanye amagama, uhlelo lwe-hydraulic lwe-QY70K lungalawula amandla enjini nokugeleza kokumpompa kukawoyela wokubacindezela ngesikhathi sangempela ngokusho kwenhloso yokuphakamisa yomshayeli. Ngokwemigomo ye-layman, uhlelo lungakwazi "ukunika" amandla amaningi nokugeleza njengoba "kusetshenzisiwe". , Ayikho inki, akukho doti!
