ho bua ka Excavator(1)
E khethiloe e le mochini o boima oa kaho, excavator, eo hape e tsejoang e le mochini oa ho epolla, o tsejoang hape e le excavator, Ke mochini o tsamaisang lefats'e o sebelisang nkho ho epolla lisebelisoa ka holimo kapa ka tlase ho bokaholimo ebe o e kenya koloing ea lipalangoang kapa ho e laolla. ho isa setokong.
Thepa e epolotsoeng ke excavator haholo-holo mobu, mashala, silt, mobu le lefika ka mor'a hore pele ho loosening.Ha re nahana ka ntshetsopele ya mechine ea kaho lilemong tsa morao tjena, ntshetsopele ya excavators ke batlang e potlakile, 'me excavators fetohile e mong oa bohlokoa ka ho fetisisa. metjhini ya kaho kahong ya boenjineri
E arotsoe ka li-excavator tsa motlakase tse ka hare le li-excavator tsa motlakase ho latela mokhoa oa ho khanna, ho ea ka tsela ea ho tsamaea, e ka aroloa ka li-excavator tsa crawler le li-excavator tse mabili.
Ho ea ka mokhoa oa phetisetso, e ka boela ea aroloa ka li-excavators tsa hydraulic le li-excavators tsa mechine, Haeba ho ea ka nkho, e na le litsela tse peli: ho epolloa ha likharafu ka pele, ho epolloa ha backhoe.
Boima ba ts'ebetso ke e 'ngoe ea likarolo tse tharo tsa bohlokoa tsa moepolli (matla a enjene, matla a bakete, boima ba ts'ebetso), Boima ba ts'ebetso bo lekanya boemo ba moepo le ho lekanya moeli o kaholimo oa matla a ho cheka a moepolli.
Matla a ho cheka≦m;
Boima ba ho sebetsa m: coefficient e khomarelang pakeng tsa fatše le sehahabi, Haeba matla a ho cheka a feta moeli ona, tabeng ea backhoe, moepolli o tla thella ebe o huleloa pele, e leng kotsi haholo.Boemong ba kharafu, moepolli o tla thellela morao.Matla a ho cheka, bakeng sa matla a ho cheka, matla a ho cheka a arotsoe haholo-holo ka matla a ho cheka forearm le matla a ho cheka nkho.
Lintlha tsa liketso tsa matla a mabeli a ho cheka ke metso ea leino la nkho (molomo oa nkho), empa matla a fapane.Matla a ho cheka forearm a tsoa ho forearm cylinder;matla a ho cheka bakete a tsoa moqomong oa oli oa bakete.
Khatello e khethehileng ea fatše, boholo ba khatello e khethehileng ea fatše e etsa qeto ea maemo a fatše a loketseng hore moepi a sebetse. = boima ba ho sebetsa ÷ sebaka sohle se amanang le fatše, Latela lieta, ho bohlokoa ho kenya lieta tse nepahetseng tsa pina mochining.Bakeng sa li-excavators tsa crawler, mekhoa ea ho khetha sehahabi ke: Ha ho khoneha, leka ho sebelisa lieta tse patisaneng ka ho fetisisa.
Mefuta e tloaelehileng ea lipina: lieta tse nang le meno, lieta tse bataletseng, lieta tse bataletseng, lebelo la ho tsamaea, bakeng sa baepolli ba li-crawler, nako ea ho tsamaea e nka karolo ea leshome ea nako eohle ea ho sebetsa.
Ka kakaretso, mabelo a mabeli a ka kopana le ts'ebetso ea ho tsamaea ea excavator.Traction force, traction force e bua ka matla a hlahisoang ke excavator ha a tsamaea, e leng haholo-holo e itšetlehileng ka koloi ea maeto ea excavator.Tsena tse peli tse tsamaeang ka mokhoa oa ho tsamaea li bontša ho tsamaea. ya moepolli le bokgoni ba yona ba ho tsamaya.E ka bonahala ka mehlala ea bahlahisi ba sa tšoaneng.
Gradeability, gradeability e bolela bokhoni ba ho hloa, ho theoha, kapa ho ema holim'a moepa o tiileng, oa boemo. .E lekantsoe matla a ho phahamisa a tsitsitseng: 75% ea moroalo o fokolang, o lekantsoeng matla a phahamiso ea hydraulic: 87% ea matla a ho phahamisa li-hydraulic
Lebelo la ho sisinyeha le bolela lebelo le tloaelehileng leo moepolli a ka le fihlelang nakong ea ho sisinyeha ho tsitsitseng ha moepolli a theoloa.Sena se bolela hore lebelo le hlalosoang la ho bolaea, ha le qala, kapa ha le qhoma; .Bakeng sa mosebetsi o akaretsang oa ho epolla, Ha moepolli ona o sebetsa ho tloha ho 0 ° ho isa ho 180 °, mochini o bolaeang oa potlakisa kapa oa fokotseha, 'me ha o fetohela ho 270 ° ho ea ho 360 °, lebelo la ho bolaea le tsitsitse. mosebetsi oa ho cheka, lebelo la ho potoloha le hlalositsoeng ka holimo ha le utloahale.
Ke hore, ts'ebetso ea 'nete e hlokahalang ea ho sisinyeha ke ho potlakisa / ho fokotseha ho hlahisoang ka torque.Enjene matla, gross horsepower e bua ka tlhahiso ea matla e lekantsoeng ho flywheel ea enjene ntle le lisebelisoa tse senyang matla tse kang li-mufflers, fans, alternator le li-filters tsa moea. Matla a sebetsang (net horsepower) a bolela matla a hlahisoang a lekantsoeng ho flywheel ea enjene e nang le lisebelisoa tsohle tse jang matla joalo ka li-mufflers, fan, li-alternator le lihloela tsa moea tse kentsoeng.
Tekanyo ea lerata, lerata la excavator haholo-holo le tsoa enjeneng.Mefuta e 'meli ea lerata: tekanyo ea lerata tsebeng ea opareitara, tekanyo ea lerata ho potoloha mochini
