Moepike mochini o nang le merero e mengata oa kaho ea lefats'e oo haholo-holo o etsang ho cheka ha mobu le ho kenya thepa, hammoho le ho lokisa mobu, ho lokisa matsoapo, ho phahamisa, ho pshatla, ho heletsa, ho etsa trenching le mesebetsi e meng. Ka hona, e sebelisitsoe haholo kahong ea litsela tse kang litsela tse kholo le literene, kaho ea borokho, kaho ea litoropo, boema-fofane, boema-kepe le kaho ea paballo ea metsi. Kahoo mokhoa oa ho khetha excavator e lumellanang le morero oa hau le ho khetha mochine oa boleng bo phahameng o ka ahloloa ho latela lintlha tse latelang tsa bohlokoa.
1. Boima ba ho sebetsa:
E 'ngoe ea likarolo tse tharo tse ka sehloohong tsa moepolli, e bua ka boima ba' mele oa ho epolla ka lisebelisoa tse tloaelehileng tsa ho sebetsa, mokhanni le mafura a feletseng. Boima ba ho sebetsa bo lekanya boemo ba moepolli hape bo lekanyetsa moeli o ka holimo oa matla a ho cheka a moepolli.
2. Matla a enjene:
E 'ngoe ea likarolo tse tharo tse kholo tsa moepolli, e arotsoe ka matla a maholo le matla a marang-rang, a khethollang ts'ebetso ea matla ea moepolli.
(1) Gross power (SAE J1995) e bolela matla a tsoang a lekantsoeng lebiling la sefofane ntle le lisebelisoa tse jang matla tse kang li-mufflers, fans, alternator le li-filters tsa moea. (2) Matla a marang-rang: 1) e bolela matla a hlahisoang a lekantsoeng ka sefofane sa enjene ha lisebelisoa tsohle tse jang matla tse kang muffler, fan, jenereithara le sefe ea moea li kentsoe. 2) e bua ka matla a hlahisoang a lekantsoeng ho flywheel ea enjene ha lisebelisoa tse jang matla tse hlokahalang bakeng sa ts'ebetso ea enjene, hangata li-fan, li kentsoe.
3. Bophahamo ba bakete:
E 'ngoe ea likarolo tse tharo tse kholo tsa moepolli, e bua ka bongata ba thepa eo nkho e ka e jarang. Excavator e ka hlomelloa ka linkho tsa boholo bo fapaneng ho latela boima ba thepa. Khetho e utloahalang ea matla a libakete ke e 'ngoe ea mekhoa ea bohlokoa ea ho ntlafatsa ts'ebetso ea ts'ebetso le ho fokotsa tšebeliso ea matla.
Bophahamo ba libakete hangata bo arotsoe ka matla a libakete tse phuthetsoeng le bakete e sephara. Bokhoni bo sebelisoang hangata ba libakete tsa baepolli ba libakete bo bokelletsoeng. Bophahamo ba bakete e bokeletsoeng bo na le mefuta e 'meli ho ea ka sekhutlo sa tlhaho sa ho phomola: 1:1 e bokellaneng ea bakete ea 1:2.
4. Matla a ho cheka
E kenyelletsa matla a ho cheka a letsoho la ho cheka le matla a ho cheka bakete. Matla a mabeli a cheka a na le matla a fapaneng. Matla a ho cheka a letsoho la ho cheka a tsoa ho cylinder ea letsoho la ho cheka, ha matla a ho cheka a nkho a tsoa ho cylinder ea bakete.
Ho ea ka lintlha tse fapaneng tsa ts'ebetso ea matla a ho cheka, lipalo le mekhoa ea ho lekanya ea excavator e ka aroloa ka mekhahlelo e 'meli:
(1) Tekanyetso ea ISO: Sebaka sa ts'ebetso se pheletsong ea lehare la bakete.
(2) SAE, PCSA, GB standard: Sebaka sa ts'ebetso se ntlheng ea leino la bakete.
5. Sebaka sa ho sebetsa
E bua ka sebaka se ka hare sa mohala o hokahanyang lintlha tsa boemo bo feteletseng tseo ntlha ea leino la bakete e ka fihlang ho eona ha moepo o sa potoloha. Hangata li-excavators li sebelisa litšoantšo ho hlalosa ka ho hlaka mefuta e sebetsang. Letoto la ts'ebetso ea moepolli hangata le hlahisoa ke li-parameter tse joalo ka radius e phahameng ea ho cheka, botebo bo boholo ba ho cheka, le bophahamo bo boholo ba ho cheka.
6. Boholo ba lipalangoang
E bua ka litekanyo tse ka ntle tsa excavator sebakeng sa lipalangoang. Boemo ba lipalangoang ka kakaretso bo bua ka motho ea epollang ea emeng sebakeng se bataletseng, lifofane tse bohareng tsa sebaka se kaholimo le tse tlase li tšoana, moqomo oa bakete le moqomo oa letsoho oa ho cheka o atolosoa ho fihlela bolelele bo bolelele ka ho fetesisa, boom e theoleloa ho fihlela sesebelisoa se sebetsang se ama fatše, 'me likarolo tsohle tse bulehileng li boemong bo koetsoeng ba moepolli.
7. Lebelo la Slewing le torque ea ho senya
(1) Lebelo la slewing le bolela lebelo le phahameng ka ho fetisisa leo moepi a ka le fihlelang ha a potoloha ka mokhoa o tsitsitseng ha a laolloa. Lebelo le tšoailoeng la ho hlaba ha le bolele lebelo la ho hlaba nakong ea ho qala kapa ho qhoma. Bakeng sa maemo a kakaretso a ho cheka, ha moepo o sebetsa ho tloha ho 0 ° ho ea ho 180 °, koloi e bolaeang e potlakisa le ho fokotseha. Ha e potoloha ho ea ho 270 ° ho ea ho 360 °, lebelo la ho bolaea le fihla botsitso.
(2) Torque e otlolohileng e bolela torque e phahameng haholo eo mochini oa moepo o ka hlahisang. Bongata ba torque e hlabang bo etsa qeto ea bokhoni ba moepolli oa ho potlakisa le ho pshatla sekepe, 'me ke pontšo ea bohlokoa ea ho lekanya ts'ebetso ea moepolli.
8. Lebelo la ho tsamaea le ho hula
Bakeng sa baepolli ba li-crawler, nako ea maeto e nka karolo ea 10% ea kakaretso ea nako ea ho sebetsa. Ka kakaretso, baepolli ba na le lisebelisoa tse peli tsa maeto: lebelo le phahameng le lebelo le tlase. Lebelo le habeli le ka kopana hantle le ho hloa ha moepolli le tšebetso ea maeto a fatše a bataletseng.
(1) Matla a ho hula a bolela matla a hulang a tšekaletseng a hlahisoang ha moepolli a tsamaea sebakeng se tšekaletseng. Lintlha tse ka sehloohong tse susumetsang li kenyelletsa ho falla ha likoloi ka lebelo le tlaase la koloi ea maeto, khatello ea ho sebetsa, bophara ba mabili a koloi, boima ba mochine, joalo-joalo.
(2) Lebelo la ho tsamaea le bolela lebelo le phahameng la ho tsamaea la moepolli ha a tsamaea sebakeng se tloaelehileng. Lebelo la ho epolla ha hydraulic excavator hangata ha le fete 6km/h. Crawler hydraulic excavator ha e loketse maeto a malelele. Lebelo la ho tsamaea le matla a ho hula a bontša bokhoni ba ho tsamaea le bokhoni ba ho epa.
9. Bokhoni ba ho hloa
Bokhoni ba ho hloa hloahloa ba moepolli bo bolela bokhoni ba ho hloa, ho theoha, kapa ho emisa moepeng o tiileng, o bataletseng. Ho na le mekhoa e 'meli ea ho e hlalosa: angle le peresente: (1) The angle ea ho hloa θ hangata ke 35°. (2) Peresente ea tafole tanθ = b/a, ka kakaretso 70%. Lethathamo la microcomputer hangata ke 30 ° kapa 58%.
10. Matla a ho phahamisa
Bokhoni ba ho phahamisa bo bolela bonyane ba matla a ho phahamisa a tsitsitseng a lekantsoeng le matla a ho phahamisa haeteroliki.
(1) E lekantsoe matla a ho phahamisa a tsitsitseng 75% ea moroalo o fokolang.
(2) E lekantsoe matla a ho phahamisa li-hydraulic 87% ea matla a ho phahamisa li-hydraulic.
Ho itšetlehile ka boitsebiso bo ka holimo, u ka tseba hore na ke moepi ofe eo e leng khetho e ntle ka ho fetisisa ho latela maemo a mosebetsi oa boenjiniere le litekanyetso tsa theknoloji ea thepa.
Baetsi ba Sechaena ba tsebahalang ba kenyelletsaXCMG \SANY\ZOOMLION\ LIUGONG \ LONKING \ le bahlahisi ba bang ba litsebi. U ka ikopanya le rona ka theko e ntle ka ho fetisisa!
