ExcavatorMuchina wekuvaka wepasi une zvinangwa zvakawanda unonyanya kuita kuchera pasi uye kurodha, pamwe nekugadzirisa ivhu, kugadziriswa kwemateru, kusimudza, kupwanya, kuputsa, kuchera uye mamwe mabasa. Naizvozvo, yakashandiswa zvakanyanya mukuvaka migwagwa senge migwagwa mikuru uye njanji, kuvaka mabhiriji, kuvaka maguta, nhandare dzendege, madoko uye kuvaka kwekuchengetedza mvura. Saka nzira yekusarudza yekuchera inokodzera purojekiti yako uye sarudza yemhando yepamusoro yekuchera inogona kutongwa kubva pane zvinotevera zvinhu zvakakosha.
1. Kushanda uremu:
Imwe yeatatu makuru ma parameter emucheri, inoreva huremu hwese hwemucheri ane akajairwa maturusi ekushanda, mutyairi uye yakazara mafuta. Huremu hwekushandisa hunotaridza mwero wemucheri uye zvakare inotara muganhu wepamusoro wesimba rekuchera remucheri.
2. Simba reinjini:
Imwe yeatatu makuru ma paramita emucheri, yakakamurwa kuita gross simba uye net simba, iyo inosarudza kushanda kwesimba kweiyo excavator.
(1) Gross power (SAE J1995) inoreva simba rinobuda rakayerwa painjini flywheel isina zvinhu zvinopedza simba zvakaita semamufflers, mafeni, maalternator nemafirita emhepo. (2) Simba remambure: 1) inoreva simba rekubuda rakayerwa painjini flywheel kana zvese zvinoshandisa simba senge muffler, fan, jenareta uye sefa yemhepo zvakaiswa. 2) inoreva simba rekubuda rakayerwa painjini flywheel kana zvinhu zvinoshandisa simba zvinodikanwa pakushanda kweinjini, kazhinji mafeni, akaiswa.
3. Bucket kukwana:
Imwe yematatu makuru ma paramita emucheri, inoreva huwandu hwezvinhu izvo bhaketi rinogona kurodha. Iyo yekuchera inogona kuve yakashongedzerwa nemabhaketi ehukuru hwakasiyana zvichienderana nekuwanda kwezvinhu. Kusarudzwa kunonzwisisika kwehuwandu hwebhakiti ndiyo imwe yenzira dzakakosha dzekuvandudza kushanda zvakanaka uye kuderedza kushandiswa kwesimba.
Bucket huwandu hunowanzo kupatsanurwa kuita akatutirwa bhakiti reti uye flat bhaketi huwandu. Iyo inowanzo shandiswa calibrated bucket capacity yevanochera yakatutirwa bhakiti reti. Hututu hwebucket rehutatu hune marudzi maviri zvichienderana neayo echisikigo yekuzorora: 1: 1 yakatutirwa bhaketi remuhomwe uye 1: 2 yakatutirwa bhaketi kugona.
4. Simba rekuchera
Inosanganisira simba rekuchera reruoko rwekuchera uye simba rekuchera remugomo. Masimba maviri ekuchera ane masimba akasiyana. Simba rekuchera reruoko rwekuchera rinobva pahumburumbira yeruoko rwekuchera, nepo simba rekuchera remugomo rinobva mubucket cylinder.
Zvinoenderana neakasiyana mapoinzi echiito chesimba rekuchera, kuverenga uye kuyerwa nzira dzemucheri anogona kukamurwa kuita mapoka maviri:
(1) ISO chiyero: Nzvimbo yekuita iri pamucheto webucket blade.
(2) SAE, PCSA, GB chiyero: Nzvimbo yekuita iri pamucheto wezino remubhaketi.
5. Basa rekushanda
Inoreva nzvimbo yemukati yemutsara unobatanidza nzvimbo yakanyanyisa nzvimbo iyo iyo muromo webucket zino inogona kusvika kana iyo yekuchera isiri kutenderera. Vanochera vanowanzo shandisa magiraidhi kuratidza zvakajeka huwandu hwekushanda. Iro rekushandisa remucheri rinowanzo kuratidzwa ne parameters senge yakakura yekuchera radius, yakanyanya kudzika yekuchera, uye kureba kwekuchera.
6. Saizi yekutakura
Inoreva zviyero zvekunze zvemucheri mumamiriro ekutakura. Mamiriro ekufambisa anowanzo anoreva kune wekuchera akamiswa panzvimbo yakati sandara, ndege dzepakati nepakati dzepamusoro nepamusoro miviri dzakafanana, silinda yebhakiti uye silinda yeruoko yekuchera inotambanudzirwa kusvika pakureba, boom inodzikiswa kusvika chishandiso chekushanda chinobata pasi, uye zvikamu zvese zvinovhurika zviri munzvimbo yakavharwa yeanochera.
7. Slewing speed uye slewing torque
(1) Slewing speed inoreva mwero wepakati wekumhanya unogonekwa nemucheri kana achitenderera akadzikama kana aburutswa. Sipidhi yakamisikidzwa yekubaya hairevi kumhanya kwekuuraya panguva yekutanga kana braking. Pamamiriro ekunze ekuchera, kana mucheri akashanda mumhando ye0 ° kusvika 180 °, mota inouraya inomhanyisa uye inodzikisira. Kana ichitenderera kusvika pachiyero che270 ° kusvika 360 °, kumhanya kwekuuraya kunosvika pakugadzikana.
(2) Slewing torque inoreva torque yakakura iyo iyo yekuchera inoburitsa system yekuchera. Saizi ye torque inouraya inosarudza kugona kwemucheri kuti akurumidze uye kubhureki slewing, uye chiratidzo chakakosha chekuyera kuita kwemucheri.
8. Kumhanya kwekufamba uye kudhonza
Kune vanochera vanochera, nguva yekufamba inosvika gumi muzana yenguva yese yekushanda. Kazhinji, vanochera vane magiya maviri ekufambisa: kumhanya kwakanyanya uye kuderera. Iyo mbiri yekumhanya inokwanisa kusangana nekukwira kwemucheri uye kuita kwekufamba kwepasi kwakadzikama.
(1) Simba rekukweva (traction force) zvinoreva simba rekudhonza rakachinjika rinogadzirwa kana mucheri anenge achifamba panzvimbo yakachinjika. Zvinonyanya kupesvedzera zvinhu zvinosanganisira kudzika-kumhanya kwegiya rekufambisa mota, kushanda nesimba, dhiraivha vhiri pitch dhayamita, uremu hwemuchina, nezvimwe. Vanochera kazhinji vane simba guru rekukwevera, iro rinowanzoita 0.7 kusvika 0.85 nguva yehuremu hwemuchina.
(2) Kumhanya kwekufamba kunoreva kumhanyisa kwekufamba kwemucheri kana uchifamba panzvimbo yakajairwa. Kumhanya kwekufamba kwevanochera ma hydraulic excavators kazhinji haapfuure 6km/h. Crawler hydraulic excavators haikodzeri kufamba kure-kure. Kumhanya kwekufamba uye simba rekudhonza rinoratidza kugona uye kugona kwekufamba kwemucheri.
9. Kukwanisa kukwira
Kugona kukwira kweanochera (excavator) zvinoreva kugona kukwira, kudzika, kana kumira pamateru akasimba. Pane nzira mbiri dzekuzvitaura: kona uye muzana: (1) Kona yekukwira θ inowanzoita 35°. (2) Muzana tafura tanθ = b/a, kazhinji 70%. Iyo microcomputer index inowanzoita 30 ° kana 58%.
10. Kusimudza simba
Kusimudza simba kunoreva kudiki kweiyo yakatemerwa yakagadzikana yekusimudza kugona uye yakayerwa hydraulic yekusimudza kugona.
(1) Yakatemerwa yakagadzikana yekusimudza simba 75% yetipping mutoro.
(2) Yakatemerwa hydraulic kusimudza simba 87% ye hydraulic kusimudza simba.
Zvichienderana neruzivo rwuri pamusoro, unogona kuona kuti ndeipi yekuchera ndiyo yakanakisa sarudzo zvichienderana nemamiriro ekushanda einjiniya uye tekinoroji paramita yemidziyo.
Vanozivikanwa vagadziri veChinese vanosanganisiraXCMG \SANY\ZOOMLION\ LIUGONG \ LONKING \ nevamwe vagadziri vehunyanzvi. Unogona kutibvunza nemutengo wakanakisa!
