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. Pakumisa mota, mota inomhanya inoburitsa chiutsi chitema, uye inonzwa kunge mota yadzoka. ④320c haina intercooler, uye iyo 5-8 giya yakadzimwa Speed inenge 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 inogadziriswa, dunhu rakajairika, uye kuyerera kwe hydraulic ndiko Kuidzikisa pasi, utsi hwakasviba. inosara, pombi yekupedza injini haina mhepo, iyo hydraulic action yapera, 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 rikasagadziriswa 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 yepombi 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, kana kutodhonza masilinda uye kumwe kutadza.
2. Kana injini ichibudisa utsi hutema huzhinji uye kudonha kwesimba kwakakura, zvakakosha kuti utarise kana pane kubuda kwemafuta mupombi yekupinza yeturbocharger, vhiri returbine returbocharger, uye kuti mablades akatyoka. , yakasakara, kana kuremara. , Kana paine kukuvadzwa kwekutsva mudzimba dzeturbocharger, uye kana iyo impeller shaft clearance inodarika 3 mm.
Kana izvi zviitiko zvikaitika, turbocharger inofanira kutsiviwa.
3. Tarisa uone kana pombi yedhiziri nejekitari yemafuta 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 nekutadza kwe dhiziri (cylinder-breaking experiment inogona kushandiswa kutarisa kunaka kweinjector) .Kana iyo yekuchera inowanzobudisa 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 rakajairika.
5. Mucheri haana simba apo injini inobudisa utsi hutema, uye pane kuchinja kwezwi kana injini iri kushanda pasi pemutoro. Panguva ino, zvingangoita kuti simba repombi ye hydraulic rinopfuura simba rejini yekukonzera utsi hutema. Panguva ino, tanga kuderedza kuyerera uye kudzvinyirira kwe hydraulic pump.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!
