Izvo zvinodikanwa kutarisa kubva kune matatu maficha: pombi, hydraulic lock uye pilot system.
1.Kutanga ona kana pasina chaizvoizvo chiito. Dzima injini, itangezve, uye edza zvakare, hapana chinhu.
2.Mushure mekutanga mota, tarisa kudzvanywa kwepombi pane yekutarisa uye ona kuti kuruboshwe nekurudyi pombi yekumanikidza iri pamusoro pe4000kpa, iyo inobvisa kwenguva pfupi dambudziko repombi.
3.Chitubu paburi re hydraulic nekumisa lever yemucheri chakatyoka. Ini ndinoshamisika kana switch pane yekuvhura uye yekumisa lever haigone kushandurwa panzvimbo. Ini ndinopfupisa switch yacho zvakananga ndoita chiito, asi hapasati pave nemhinduro. Tarisa dunhu uye shandisa multimeter kuyera zvakananga hydraulic lock solenoid valve. Mhepo yetambo mbiri inopfuura 25V, uye kushorwa kwevhavhavha ye solenoid inowanzoitika kana kuyerwa. Mushure mokubvisa zvakananga solenoid valve uye kuisimbisa, zvakaonekwa kuti solenoid valve core yakafamba panzvimbo, nokudaro kubvisa dambudziko re hydraulic lock solenoid valve.
4.Tarisa mutyairi wendege uye kuyera kumanikidza kwemutyairi kuita 40,000kpa, zvinova zvakajairika uye bvisa dambudziko repombi yekutyaira.
5.Test drive zvakare, hapana chiito. Ndichifungidzira dambudziko remutyairi wendege, ndakanyatso patsanura mutsara wemutyairi wevharuvhu yekudzora bhaketi pavharuvhu huru yekudzora ndokufambisa ruoko rwebhaketi. Hapana mafuta e hydraulic akabuda. Yakanga yakatemwa kuti dambudziko remutyairi wendege rakakonzera kuti mucheri asave nekufamba mushure mekugadzirisa pombi. , hapana dambudziko kana uchifamba.
6.Basa rinotevera nderekutarisa chikamu chemutsara wemafuta emutyairi nechikamu chinotangira kubva papombi yekutyaira uye kuona kuti pombi yemafuta yekutyaira kuseri kwevharuvhu yenzira dzakawanda yakavharika. Mushure mekuibvisa, kukanganisa kunobviswa.
Kana iyo hydraulic excavator ikatadza kushanda, zvinowanzodikanwa kutevedzera zvinotevera kutevedzana kuti uongorore uye kugadzirisa kukanganisa.
1 Tarisa hydraulic mafuta level
Kuvharika kweoiri suction filter element mu hydraulic oil circuit, kusveta kusina mafuta edunhu (kusanganisira yakaderera mafuta level mu hydraulic oil tank), nezvimwe zvinokonzeresa kuti hydraulic pombi isanyatso kunwisa oiri kana kutadza kutora mafuta, ayo ichatungamira zvakananga kune kusakwana kwemafuta kudzvinyirira mu hydraulic oiri redunhu. , zvichiita kuti mucheri usave nekufamba. Kuongororwa kwemhando iyi yekukanganisa kunogona kubviswa nekutarisa iyo hydraulic oiri tank peji uye chiyero chekusvibiswa kweiyo hydraulic oiri.
2 Tarisa uone kana hydraulic pombi yakashata
Vanochera maHydraulic vanowanzo shandisa maviri kana anopfuura mapombi makuru kupa mafuta ekumanikidza kune sisitimu. Iwe unogona kutanga waona kana simba reinjini yekubuda shaft rinogona kuendeswa kune yega hydraulic pombi. Kana iyo isingakwanisi kuendeswa, ipapo dambudziko rinoitika mukubuda kwemagetsi ejini. Kana ichigona kutapurirana, kukanganisa kunogona kuitika pane hydraulic pombi. Muchiitiko ichi, unogona kuisa gauge yeoiri ine chiyero chakakodzera pachiteshi chekubuda chepombi yega yega hydraulic kuyera kubuda kwepombi, uye woienzanisa neiyo theory yekubuda kwekumanikidza kukosha kwepombi yega yega kuti uone kana iyo hydraulic pombi. ane mhosva.
3 Tarisa uone kana vharuvhu yekukiya kuchengetedza yakanganisa
Ivhavha yekuvhara yekudzivirira ndeye mechanical switch iri mu cab. Inogona kudzora kuvhurwa nekuvhara kweyepasi-kudzvanywa mafuta seti uye matatu seti yeakaenzana kudzora kudzvinyirira mavharuvhu mu cab, ayo ari kuruboshwe nekurudyi mabatiro ekutonga uye yekufamba kusunda-dhonza tsvimbo. Kana iyo vharafu yekuvhara yevhavha yakanamatira kana kuvharika, oiri haigone kusundira main control valve kuburikidza neproportional pressure control valve, zvichikonzera kutadza kwemuchina wese kushanda. Replacement nzira inogona kushandiswa kugadzirisa kukanganisa uku.
Kana iwe uchida kutenga hydraulic pombi kana hydraulic system inoenderana nemidziyo panguva yekugadzirisa, unogonataura nesu. Kana iwe uchida kutenga yakashandiswa excavator, iwe unogona zvakare kutarisa kune yeduyakashandiswa excavator chikuva. CCMIE-yako-yekumira mutengesi wekuchera uye zvishongedzo.
