Ndikofunikira kuyang'ana kuchokera kuzinthu zitatu: mpope, loko ya hydraulic ndi dongosolo loyendetsa.
1.Choyamba dziwani ngati palibe chochita. Zimitsani injiniyo, yiyambitsenso, ndikuyesanso, komabe palibe.
2.Pambuyo poyambitsa galimotoyo, yang'anani kuthamanga kwa mpope pa gulu loyang'anira ndikupeza kuti kumanzere ndi kumanja kwapampope kuli pamwamba pa 4000kpa, zomwe zimathetsa kwakanthawi vuto la mpope.
3.Chidutswa cha kasupe pa hydraulic kutsegula ndi kuima lever ya excavator wathyoka. Ndikudabwa ngati chosinthira chotsegulira ndi choyimitsa sichingasinthidwe m'malo mwake. Ndimafupikitsa chosinthira mwachindunji ndikuchitapo kanthu, koma palibe yankho. Yang'anani kuzungulira ndikugwiritsa ntchito multimeter kuti muyese mwachindunji hydraulic lock solenoid valve. Mpweya wa mawaya awiriwa ndi oposa 25V, ndipo kukana kwa valve solenoid ndikwachilendo pamene kuyeza. Pambuyo pochotsa mwachindunji valavu ya solenoid ndikuyipatsa mphamvu, zinapezeka kuti nsonga ya valve solenoid inasuntha, motero kuthetsa vuto la hydraulic lock solenoid valve.
4.Yang'anani machitidwe oyendetsa ndege ndikuyesa kuthamanga kwa oyendetsa kuti akhale pafupifupi 40,000kpa, zomwe ndi zabwinobwino ndikuchotsa vuto la mpope woyendetsa.
5.Yesani kuyendetsa kachiwiri, komabe palibe chochita. Poganizira vuto la woyendetsa ndege, ndinachotsa mwachindunji mzere woyendetsa ndowa pa valve yaikulu yolamulira ndikusuntha mkono wa ndowa. Palibe mafuta a hydraulic omwe adatuluka. Zinatsimikiziridwa kuti vuto la mzere woyendetsa ndege linapangitsa kuti wofukulayo asasunthike pambuyo pokonza mpope. , palibe vuto poyenda.
6.Ntchito yotsatirayi ndikuyang'ana gawo la mzere wa mafuta oyendetsa ndi gawo loyambira pa pampu yoyendetsa ndege ndikupeza kuti chitoliro cha mafuta oyendetsa kumbuyo kwa valve yoyendetsa maulendo ambiri chatsekedwa. Pambuyo poyeretsa, cholakwikacho chimachotsedwa.
Pamene hydraulic excavator ikalephera kugwira ntchito, nthawi zambiri pamafunika kutsatira zotsatirazi kuti muzindikire ndikuthetsa vutolo.
1 Onani kuchuluka kwamafuta a hydraulic
Kutsekeka kwa gawo lazosefera zamafuta mumayendedwe amafuta a hydraulic, kuyamwa kopanda mafuta (kuphatikiza mafuta otsika mu tanki yamafuta a hydraulic), ndi zina zotere kumapangitsa kuti pampu ya hydraulic itenge mafuta osakwanira kapena kulephera kuyamwa mafuta, omwe. zidzatsogolera mwachindunji kupsinjika kwamafuta osakwanira mumayendedwe amafuta a hydraulic. , zomwe zimapangitsa kuti wofukulayo asasunthe. Kuzindikira kwa vuto lamtunduwu kumatha kuthetsedwa poyang'ana tsamba la tank mafuta a hydraulic ndi kuchuluka kwa kuipitsidwa kwamafuta a hydraulic.
2 Onani ngati pampu ya hydraulic ndiyolakwika
Ofukula ma hydraulic nthawi zambiri amagwiritsa ntchito mapampu akuluakulu awiri kapena kuposerapo kuti apereke mafuta opanikizika kudongosolo. Mutha kudziwa kaye ngati mphamvu ya shaft yotulutsa injini imatha kufalikira ku pampu iliyonse yama hydraulic. Ngati sangathe kupatsirana, ndiye kuti vuto limapezeka mu mphamvu ya injini. Ngati chitha kupatsirana, cholakwikacho chikhoza kuchitika pampopi ya hydraulic. Pankhaniyi, mutha kuyika choyezera kuthamanga kwamafuta chokhala ndi mtundu woyenera pa doko la pampu iliyonse ya hydraulic kuti muyeze kuthamanga kwa mpope, ndikuyerekeza ndi kuchuluka kwamphamvu kwapampu iliyonse kuti muwone ngati pampu ya hydraulic ndi zolakwika.
3 Onani ngati valavu yotsekera chitetezo ndiyolakwika
Valavu yotsekera chitetezo ndi chosinthira chamakina chomwe chili mu cab. Ikhoza kulamulira kutsegula ndi kutseka kwa kayendedwe ka mafuta otsika kwambiri ndi ma seti atatu a ma valve oyendera mphamvu mu kabati, monga zogwirira ntchito kumanzere ndi kumanja ndi ndodo yokankhira maulendo. Vavu yotsekera chitetezo ikakakamira kapena kutsekedwa, mafuta sangathe kukankhira valavu yayikulu yowongolera kudzera pamagetsi owongolera, zomwe zimapangitsa kuti makina onse asagwire ntchito. Njira yowonjezera ingagwiritsidwe ntchito kuthetsa vuto ili.
Ngati mukufuna kugula hydraulic pump kapena hydraulic system zokhudzana ndi zida panthawi yokonza, muthaLumikizanani nafe. Ngati mukufuna kugula excavator yogwiritsidwa ntchito, mutha kuyang'ananso athuntchito excavator nsanja. CCMIE-omwe amakugulitsirani zofukula ndi zowonjezera.
