Kapangidwe koyambira ndi mfundo yogwirira ntchito ya excavator, sprocket ya Azerbaijan Excavator
1. Kapangidwe konse ka chofukula cha hydraulic cha chidebe chimodzi
Kapangidwe konse ka chotsukira cha hydraulic cha chidebe chimodzi kumaphatikizapo chipangizo chamagetsi, chipangizo chogwirira ntchito, njira yodulira, njira yogwiritsira ntchito, makina otumizira, njira yoyendera ndi zida zothandizira, ndi zina zotero.
Chida chamagetsi chogwiritsidwa ntchito kwambiri choyezera ma hydraulic excavator, gawo lalikulu la makina otumizira ma hydraulic, makina oyezera ma slewing, zida zothandizira ndi kabati zonse zimayikidwa pa nsanja yoyezera ma slewing, yomwe nthawi zambiri imatchedwa upper turntable. Chifukwa chake, choyezera ma hydraulic cha chidebe chimodzi chikhoza kugawidwa m'magawo atatu: chipangizo chogwirira ntchito, chapamwamba choyezera ma turntable ndi makina oyendera.
Chofukulacho chimasintha mphamvu ya mankhwala ya mafuta a dizilo kukhala mphamvu yamakina pogwiritsa ntchito injini ya dizilo, ndipo mphamvu yamakina imasinthidwa kukhala mphamvu ya hydraulic pogwiritsa ntchito hydraulic plunger pump. Mphamvu ya hydraulic imagawidwa ku chinthu chilichonse chogwira ntchito (hydraulic cylinder, rotary motor + reducer, walking motor + reducer) pogwiritsa ntchito hydraulic system, kenako mphamvu ya hydraulic imasinthidwa kukhala mphamvu yamakina pogwiritsa ntchito chinthu chilichonse chogwira ntchito, kuti chipangizo chogwira ntchito chiziyenda bwino, rotational rotary platform ndi mayendedwe oyenda a makina onse.
Chachiwiri, makina opangira magetsi
1, njira yotumizira mphamvu yofukula ndi iyi:
1) Njira yotumizira mphamvu yoyendera: injini ya dizilo-cholumikizira-pampu yamadzimadzi (mphamvu yamakina imasinthidwa kukhala mphamvu yamadzimadzi)-valavu yogawa-galimoto yozungulira yolumikizana yozungulira (mphamvu yamadzimadzi imasinthidwa kukhala mphamvu yamakina)-choyendetsa chochepetsera-choyendetsa mawilo-njira yoyenda-choyendetsa bwino.
2) Njira yotumizira yozungulira: injini ya dizilo-cholumikizira-pampu yamadzimadzi (mphamvu yamakina imasinthidwa kukhala mphamvu yamadzimadzi)-valavu yogawa-mota yozungulira (mphamvu yamadzimadzi imasinthidwa kukhala mphamvu yamakina)-chothandizira chochepetsera-chozungulira-kuti chikwaniritse kuyenda kozungulira.
3) Njira yotumizira ma boom: injini ya dizilo-cholumikizira-pampu ya hydraulic (mphamvu yamakina imasinthidwa kukhala mphamvu ya hydraulic)-valavu yogawa-silinda ya boom (mphamvu ya hydraulic imasinthidwa kukhala mphamvu yamakina)-kuti ikwaniritse kuyenda kwa boom.
4) Njira yotumizira ndodo: injini ya dizilo-cholumikizira-pampu ya hydraulic (mphamvu yamakina imasinthidwa kukhala mphamvu ya hydraulic) - silinda yogawa valavu-stick (mphamvu ya hydraulic imasinthidwa kukhala mphamvu yamakina) - kuti ikwaniritse kuyenda kwa ndodo.
5) Njira yotumizira zinthu kuchokera ku chidebe: injini ya dizilo - cholumikizira - pampu yamadzimadzi (mphamvu yamakina imasinthidwa kukhala mphamvu yamadzimadzi) - valavu yogawa - silinda ya chidebe (mphamvu yamadzimadzi imasinthidwa kukhala mphamvu yamakina) - kuti chidebe chiziyenda bwino.
1. Gudumu lotsogolera 2, cholumikizira chapakati 3, valavu yowongolera 4, choyendetsera chomaliza 5, mota yoyendera 6, pampu ya hydraulic 7 ndi injini.
8. Valavu ya solenoid yothamanga 9, valavu ya solenoid ya brake yosweka 10, mota yosweka 11, makina osweka 12 ndi chithandizo chosweka.
2. Malo opangira magetsi
Chipangizo chamagetsi cha single bucket hydraulic excavator chimagwiritsa ntchito injini ya dizilo yoziziritsidwa ndi madzi yokhala ndi mphamvu yoyezera ya ola limodzi.
3. Njira yotumizira
Dongosolo lotumizira la chitoliro cha hydraulic cha chidebe chimodzi limatumiza mphamvu yotulutsa ya injini ya dizilo ku chipangizo chogwirira ntchito, chipangizo chodulira, makina oyendera, ndi zina zotero. Pali mitundu yambiri ya machitidwe otumizira ma hydraulic a ma chitoliro cha hydraulic cha chidebe chimodzi, omwe nthawi zambiri amagawidwa malinga ndi kuchuluka kwa mapampu akuluakulu, njira yosinthira mphamvu ndi kuchuluka kwa ma circuits. Pali mitundu isanu ndi umodzi ya machitidwe owerengera, monga dongosolo lowerengera la single-pump kapena double-pump single-loop quantitative system, double-pump double-loop quantitative system, multi-pump multi-loop power-sharing variable system, double-pump double-loop full-power variable system ndi multi-pump multi-loop quantitative kapena variable mixing system. Malinga ndi njira yoyendetsera mafuta, imatha kugawidwa m'magawo otseguka ndi otseka. Imagawidwa m'magawo angapo ndi machitidwe ofanana malinga ndi njira yoperekera mafuta.
1. Drive plate 2, coil spring 3, stop pin 4, friction plate 5 ndi shock absorber assembly.
6. Choletsa 7, mpando woyikira kumbuyo kwa injini 8 ndi mpando woyikira kutsogolo kwa injini.
Dongosolo la hydraulic komwe kutuluka kwa pampu yayikulu kuli ndi mtengo wokhazikika ndi dongosolo la hydraulic lochuluka; M'malo mwake, kuchuluka kwa kuyenda kwa pampu yayikulu kumatha kusinthidwa ndi dongosolo lowongolera, lomwe limatchedwa dongosolo losinthasintha. Mu dongosolo la kuchuluka, chowunikira chilichonse chimagwira ntchito pamlingo wokhazikika woperekedwa ndi pampu yamafuta popanda kudzaza, ndipo mphamvu ya pampu yamafuta imatsimikiziridwa malinga ndi kuchuluka kwa kuyenda kokhazikika komanso kuthamanga kwakukulu kogwira ntchito. Pakati pa makina osinthasintha, yodziwika kwambiri ndi dongosolo la mphamvu yosinthasintha yokhala ndi mapampu awiri ndi ma loops awiri, omwe amatha kugawidwa m'magulu a mphamvu yochepa ndi mphamvu yonse. Mu dongosolo la mphamvu yosinthasintha, pampu yosinthasintha yamphamvu yokhazikika ndi chowongolera mphamvu yokhazikika zimayikidwa motsatana mu kuzungulira kulikonse kwa dongosolo, ndipo mphamvu ya injini imagawidwa mofanana pa pampu iliyonse yamafuta; Dongosolo lowongolera mphamvu yonse lili ndi chowongolera mphamvu yokhazikika chomwe chimayang'anira kusintha kwa kayendedwe ka mapampu onse amafuta mu dongosolo nthawi imodzi, kuti zikwaniritse zosintha zofananira.
Mu dongosolo lotseguka, mafuta obweza a actuator amabwerera mwachindunji ku thanki yamafuta, yomwe imadziwika ndi dongosolo losavuta komanso mphamvu yabwino yotaya kutentha. Komabe, chifukwa cha mphamvu yayikulu ya thanki yamafuta, pali mwayi wambiri kuti dera lamafuta lotsika ligwirizane ndi mpweya, ndipo mpweya umalowa mosavuta mupaipi kuti uchititse kugwedezeka. Kugwira ntchito kwa chofukula cha hydraulic cha chidebe chimodzi makamaka ndi ntchito ya silinda yamafuta, koma kusiyana pakati pa zipinda zazikulu ndi zazing'ono zamafuta za silinda yamafuta ndi kwakukulu, ntchito yake ndi yobwerezabwereza, ndipo mphamvu yamagetsi ndi yokwera, kotero ma excavator ambiri a chidebe chimodzi amagwiritsa ntchito dongosolo lotseguka; Dongosolo lobweza mafuta la actuator mu dera lotsekedwa silibwerera mwachindunji ku thanki yamafuta, lomwe limadziwika ndi kapangidwe kakang'ono, kuchuluka kochepa kwa thanki yamafuta, kupanikizika kwina mu dera lobweza mafuta, kuvutika kuti mpweya ulowe mupaipi, kugwira ntchito kokhazikika, komanso kupewa kugwedezeka panthawi yobwerera m'mbuyo. Komabe, dongosololi ndi lovuta ndipo mkhalidwe wotaya kutentha ndi woipa. Mu machitidwe am'deralo monga chipangizo chodulira cha chofukula cha hydraulic cha chidebe chimodzi, dongosolo lotsekedwa la hydraulic limagwiritsidwa ntchito. Kuti muwonjezere kutayikira kwa mafuta komwe kumachitika chifukwa cha kuzungulira kwabwino ndi koipa kwa mota ya hydraulic, nthawi zambiri pamakhala pampu yowonjezera yamafuta mumakina otseka.
4. Njira yosinthira
Makina odulira amazungulira chipangizo chogwirira ntchito ndi tebulo lapamwamba kumanzere kapena kumanja kuti akumbe ndi kutsitsa. Chipangizo chodulira cha chodulira cha hydraulic cha chidebe chimodzi chiyenera kukhala chokhoza kuthandizira tebulo lodulira pa chimango, osati kupendekeka, ndikupangitsa kuti choduliracho chikhale chopepuka komanso chosinthasintha. Chifukwa chake, zodulira za hydraulic za chidebe chimodzi zimakhala ndi zida zothandizira zodulira ndi zida zotumizira zodulira, zomwe zimatchedwa zida zodulira.
