Excavator PC120-6 mfuti yayikulu valavu 723-30-90400

Malinga ndi mawonekedwe a pampu ya hydraulic, makina opangira ma hydraulic omwe amagwiritsidwa ntchito ndi hydraulic excavator pafupifupi amagawidwa m'mitundu itatu: kachulukidwe kachulukidwe, kachitidwe kosinthika, komanso kachulukidwe kake komanso kusinthasintha.
(1) Dongosolo la kuchuluka
Mu kachulukidwe kachulukidwe kamene kamagwiritsidwa ntchito ndi ofukula ma hydraulic, kutuluka kwake kumakhala kosalekeza, ndiko kuti, kutuluka sikumasintha ndi katundu, ndipo liwiro limasinthidwa ndi throttling. Malinga ndi kuchuluka ndi kuphatikizika kwa mapampu amafuta ndi mabwalo mu kachulukidwe kachulukidwe, imatha kugawidwa kukhala pampu imodzi yokhala ndi loop imodzi, pampu iwiri yamagetsi amtundu umodzi, pampu iwiri yapawiri ya loop kachulukidwe ndi makina apampu amitundu yambiri.
(2) Dongosolo losinthika
Mu makina osinthika omwe amagwiritsidwa ntchito pofukula ma hydraulic, kuwongolera kwa liwiro kosayenda kumazindikirika ndi kusinthasintha kwa voliyumu, ndipo pali njira zitatu zosinthira: kusinthasintha kwapampu-kuchulukira kwa liwiro la mota, kuchuluka kwapope-kusinthasintha kwa liwiro la mota, komanso kuwongolera kuthamanga kwapampu yosinthika. Dongosolo losinthika lomwe limatengedwa ndi hydraulic excavator nthawi zambiri limatenga kuphatikiza kwa pampu yosinthika ndi mota yochulukira kuti izindikire kusinthika kosasunthika, ndipo zonsezi ndi mapampu awiri ndi mabwalo awiri. Kutengera ngati zosinthika za mabwalo awiriwa ndizogwirizana, zitha kugawidwa m'mitundu iwiri: sub-power variable system ndi mphamvu yonse yosinthira mphamvu. Pampu iliyonse yamafuta a sub-power variable system imakhala ndi makina owongolera mphamvu, ndipo kusintha kwa pampu yamafuta kumangokhudzidwa ndi kusintha kwamphamvu kwa dera komwe kuli, komwe sikukugwirizana ndi kusinthasintha kwapampu yamafuta. dera lina, ndiko kuti, mapampu amafuta a mabwalo awiriwo pawokha amakhala ndi mphamvu zowongolera, ndipo mapampu awiri amafuta ali ndi ndowa yamphamvu yotulutsa injini; Mapampu awiri amafuta mumayendedwe osinthika amphamvu amalinganizidwa ndi mphamvu zonse zowongolera mphamvu, kotero kuti kugwedezeka kwa pampu ziwiri zamafuta kumakhala kofanana nthawi zonse.
Zosintha zamalumikizidwe ndi magalimoto ndizofanana. Zomwe zimatsimikizira kusintha kwa kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka anthu. Makina owongolera ali ndi mitundu iwiri yolumikizirana ndi makina komanso kulumikizana ndi ma hydraulic.
