Kune akawanda marudzi ehutsi hutema kubva muinjini, senge: ①Muchina une utsi hutema muchiito chimwe chete.Inongosvuta.③Zvinhu zvese zvakajairika kana iyo yakakwira throttle iri kushanda, asi haishande.Pakunopaka, mota inomhanya inoburitsa chiutsi chitema, uye inonzwa kunge mota yadzoka.④320c haina intercooler, uye iyo 5-8 giya yakadzimwa Speed inoda 250, iyo isina chinhu bhaketi chiito izere nehutsi hutema, tembiricha yemafuta uye tembiricha yemvura haina kukwirira.Tangi yedhiziri inocheneswa, giredhi yemafuta inoshandurwa, pombi yedhiziri inoshandurwa, sefa yemhepo inoshandurwa, pombi yedhiziri, muromo unogadziriswa, dunhu rakajairika, uye kuyerera kwe hydraulic ndiko Kuidzikisa pasi, utsi hwakasviba. inosara, iyo injini yekupedza pombi haina mhepo, iyo hydraulic chiito inopera, uye kumhanya kwakaderera, uye utsi hutema zvakare hudiki.
Panzvimbo dzekuvaka, tinowanzoona utsi hutema hunobva kune vanochera.Wese munhu anoziva zvakare kuti hunhu hwehutsi hutema kubva kune injini haina kukwana kupisa.Zvikonzero zvakakamurwa kuita yakashata mhepo yekudyara system, hydraulic pombi simba rinopfuura injini, uye injini.Iyo pachayo malfunctions, etc.
Hazvina kukwana kuziva chikonzero, tinofanira kuwana mhinduro inoshanda zvikuru, nokuti utsi hutema hunobva mumucheri hunoita sedambudziko diki, asi kana rikasabatwa nenguva, rinogona kuita kuti mucheri apise mafuta uye kunyange kukonzera injini kukuvara uye overhauled.
Kukundikana chiitiko
1. Chiitiko cheutsi dema chinokonzerwa nekusakwana kwemhepo kupinza kana kubuda kwepombi yekupinza.Nekuda kwekushandiswa kwenguva refu kwemucheri, kuchembera uye kukuvadzwa kwepombi yekupinza uye pombi clamp ichaita kuti pombi idonhe, inoyamwa muguruva rakakura, uye ichivharira mhepo inotonhorera, nezvimwewo, izvo zvinokonzeresa dema Smoke chiitiko. .Kana dambudziko rerudzi urwu rikaitika, rinofanirwa kugadziriswa nekufamba kwenguva, zvikasadaro injini inozoona kupera kwekutanga uye kubvaruka, kana kutodhonza masilinda uye kumwe kutadza.
2. Kana injini ichibudisa utsi hwakawanda hutema uye kudonha kwesimba kwakakura, zvakakosha kutarisa kana pane kubuda kwemafuta mupombi yekupinda ye turbocharger, vhiri returbine re turbocharger, uye kana mashizha akaputsika. , yakasakara, kana kuremara., Kana paine kukuvara kwekutanga mu turbocharger imba, uye kana iyo impeller shaft clearance inodarika 3 mm.
Kana izvi zviitiko zvikaitika, turbocharger inofanira kutsiviwa.
3. Tarisa uone kana pombi yedhiziri nejekita remafuta zvasakara uye zvichikonzerwa nehutsi hutema.Iyo yekuchera ichiri nesimba kana injini iri kubudisa utsi hutema, asi injini inomhanya inodonha (kupfuura 200 rpm).
Ichi chiitiko chinonyanya kukonzerwa nekukundikana kwe dhiziri (cylinder-breaking experiment inogona kushandiswa kutarisa kunaka kweinjector). Kana mucheki achiwanzobudisa utsi hutema uye zvakaoma kutanga, inoda kuzadzwa nekutanga. fluid.Ichi chiitiko chinoda kutarisa pombi yedhiziri.
4. Kana injini yeEGR valve yakakuvadzwa kana yakanamatira, inokonzerawo utsi hutema.Kana iyo EGR valve ikatadza, alarm ichaonekwa pachiratidziro.Kana kukanganisa kukaitika, inofanira kutsiviwa nenguva, kana zvisina kudaro ichakanganisa kushanda kweinjini, uye inogona kunzwa sezviri pachena kuti inoshandisa mafuta akawanda kupfuura basa rinowanzoitwa.
5. Mucheri haana simba apo injini inobudisa utsi hutema, uye pane kuchinja kwezwi kana injini iri kushanda pasi pemutoro.Panguva ino, zvinokwanisika kuti simba repombi ye hydraulic rinopfuura simba rejini kukonzeresa utsi hutema.Panguva ino, tanga kuderedza kuyerera uye kudzvinyirira kwepombi ye hydraulic.Kana kukanganisa kuchiripo mushure mokunge pombi ye hydraulic ichigadziriswa kune yakajairika kukosha, ipapo injini yemafuta inofanira kuongororwa.Kana kuyerera uye kudzvinyirira kwe hydraulic pump haigoni kuderedzwa, ipapo iyo hydraulic system zvikamu zvinoda kuongororwa.
Pfupiso yekutadza kweutsi hutema hweinjini yekuchera:
Kunyange zvazvo chiitiko cheutsi hutema kubva mujini chakaoma zvikuru, mukugadzirisa kwekupedzisira, zvikonzero zvekukundikana ndeizvi.Paunenge uchitarisa nekubata, iwe unofanirwa kunyatso cherechedza chiitiko chekutadza kuitira kuti uite mutongo wakanyanya.
Kana iwe uchida izvo zvine chekuita nemidziyo kana nyowani yekuchera (XCMG excavator, SANY excavator, KOMATSU excavator, nezvimwewo), unogona kutibata!
