Det-250: izici lobuchwepheshe, izithombe

Bulldozer det-250 - umshini edume ukuthi kukhiqizwa ngesikhathi Chelyabinsk isitshalo kusukela 1961. Isifinyezo det lisho ugandaganda ingenakukwazi kagesi. Isibalo sabasebenzi abangu-250 kusho ukuthi kungokwalabo isigaba traction 250 kN. Lena ugandaganda multi-purpose nge cross okusezingeni eliphezulu futhi eziningi wamavukelambuso (ngesikhathi sawo) izixazululo. On ukusebenza esiqinile ugandaganda ezingaphezu kuka ubufakazi obucacile yokuthi ikhona kuze kube manje.

isicelo

Ugandaganda isetshenziswa ngokuyinhloko emsebenzini wokwakha, ukuhambisa emhlabeni. Scarifying imishini efakwe at the ezingemuva, ivumela ziba ngcono kwangaphambilini simisiwe, phansi onamatshe, lokulungiselela okwalandela yokwakha.

On the ngogandaganda kungenziwa zifakwa emseleni bese imishini imishini for ukumba. Futhi, umshini ingasetshenziswa njengendlela oyinhloko walelo e imithi nezimayini izimboni. Ngenxa induku ithrekhi ungase ngogandaganda ngaphandle kwezinkinga ukuba ahlasele iyiphi sezwe. Futhi lapho ifakwe amathrekhi ebanzi wayifeza imisebenzi yakhe ngisho marshland.

izici lobuchwepheshe

Njengoba sekushiwo, ngokuba-yalolucwaningo 60 izici det-250 ugandaganda abangu bafanele kakhulu. On the ngogandaganda wamiswa 12-cylinder nomthamo 300 amahhashi. 4-stroke iyunithi waba ivolumu 38,9 amalitha futhi efuna ngiyinake ngokuphelele amandla omlilo ekamelweni. injini emikhulu okunjalo kwandziswa mayelana 45 amalitha ngehora ngesikhathi okukhipha esiphezulu. Umthamo fuel ithangi kwaba amalitha 700. turbocharger is hhayi ifakwe.

Det-250 ngogandaganda kwaba isibonelo lokuqala imishini ekhethekile ekhiqizwa eSoviet Union, okuyinto lithole ukudluliswa electronic. Ngenxa yalesi isixazululo zobuchwepheshe sebekwazi ngokukhululekile usebenze ugandaganda ezindaweni zasebusika nesimo. Nokho, ukudluliswa electronic kwadingeka izinkinga eziningi. Okokuqala, imoto yakhe isibe nzima kakhulu ukusebenzisa kuka izimbangi zayo i-amandla, ifakwe ukudluliswa hydromechanical. Okwesibili, ngogandaganda edingekayo ezingcono Ukupholisa uhlelo. Nokho, futhi, okwesithathu, eziningi isisindo kuholele isidingo iyunithi namandla kakhulu. Ngenxa yalokho - anda fuel izindleko nokungakwazi zisebenzisa amandla aphelele injini enamandla.

Ngokuthakazelisayo, amasampula lokuqala ngogandaganda det-250 owawufana ithangi kunokuba umshini wezolimo. Yiqiniso, lokhu kuphela okuvelayo ezingabalulekile. Eqinisweni, kusukela ugandaganda ithangi ithole kuphela izinhlelo ezimbalwa, ikakhulukazi, motor ejection ukupholisa nangamandla alo ukuze lisize amagesi qeda.

Imininingwane det-250:

1. Ubukhulu: 6,62 / 3,18 / 3,21 m.
2. Track base - 4,44 amamitha.
3. Gauge - 2,45 m.
4. Clearance - 430 mm.
5. Isisindo - 32,3 m.
6. Specific phansi kwengcindezi - 0.56 kg / cm ^2.
7. Yokudonsa amandla - amathani 25.
8. ngesivinini esiphezulu: 3 km / h travel phambili futhi 19 km / h in reverse.

I sesimanje lokuqala

Ngo-1969-ke ebanjwa sesimanje lokuqala imodeli isizinda. ugandaganda okusha lithole isiqalo "M" ukuba igama. Lase sikuhlomele nge injini entsha B-31, singakwazi ukuhlakulela 330 amahhashi. Motor 12 has amasilinda, like esasisandulele. Basuke ahlelwe ngendlela V emise. Injini entsha ngihlalé efuna ngiyinake ngokuphelele amandla omlilo chamber kanye oqondile fuel injection. Umthamo injini yehlile ku 33,9 amalitha. Ngenxa yokuthi amandla zalesi sihlahla amandla liye landa, futhi ngakhula iphango lakhe - 42,7 amalitha ihora lomsebenzi ngamunye. Ayizange ithuthuke ukudluliswa electromechanical. uphethiloli umthamo lancipha 670 amalitha. Ingqikithi yesisindo sezinto le ngogandaganda kwehle kancane - ukuze amathani 31. Ezinye izindaba zika-imodeli azishintshile.

Eyesibili sesimanje

Ngo-1989 kwaba khona yesibili nezokugcina (okungenani kuze kube manje) the sesimanje ugandaganda. Ngaphakathi the gama of the ngogandaganda ebuyekeziwe "M" Inkomba ungeze sibalo 2. Ngenxa zangaphandle yokulungiswa Dozers wayeka wafana umshini lokulwa. Le nguqulo entsha ifakwe 12 cylinder V-injini ephethe namandla 323 amahhashi. ivolumu kwawo kwakunjengokwetshe 38,9 amalitha. Injini olusha ibusa 45,3 amalitha uphethiloli ngehora uma besebenza ezindaweni amandla egcwele. Ugandaganda emuva 700 litre fuel tank, okuyinto efakwe inguqulo yokuqala. Sisindvo imoto esibuyekeziwe amathani 32. Ezinye izindaba zika-ke akuhlukile ezazingaphambi kwayo.

gumbi

Uma kuqhathaniswa namanye tractor Soviet det-250 ukukhiqizwa kuyahluka ezingeni lelisetulu gumbi induduzo. Zonke izinguqulo imoto babe esihlalweni ezimbili uhlobo cab-metal ne ezingeni eliphezulu wenduduzo. Ukumiswa yafakwa okuyiwona, kwacekela phansi izindawo eziningi kunyakaza ihlangabezane uma usebenzisa ngogandaganda. Ngo heater umgibeli gumbi, okuyinto sekuqala ukufudumala kahle isikhala elingaphakathi ngisho at eliphansi kakhulu okushisa ongaphandle. Futhi lapho kushisa ukusiza opharetha has a fan, okuyinto ejwayelekile phezu ngogandaganda.

Amajaji Insimbi abanikeze asebenza nabo wawusegunjini sizikhandle ngokwanele, opharetha lalingabulawa kalula ukulandela izinkomba ezibaluleke kakhulu. Kanye nezilawuli zihlelwe futhi ahlukaniswe imikhakha, ukuze ukudida opharetha. I gumbi ukuthi emuva ngokuphelele luphahlekwa kusukela umsindo nothuli, okuyinto ebaluleke kakhulu, uma kucatshangelwa ngokucacile ukusetshenziswa ngogandaganda. Uma iklayenti ufisa nomkhiqizi ungekwazi vimbela wezangaphakathi. Ngokuvamile, ugandaganda ungasebenza uhla lokushisa -40 kuya +40.

imishini

Det-250 ugandaganda kwaba ifakwe blade ukuma hemispherical. Bewukwati ziyahlukahluka engela yokwehlisa kanye skew. Ubuningi phuca engela kwaba ku-55 degrees, kanye skew - degrees 10. Ikhaba Yayintininiza isisindo afinyelela ku 10.5 m ^3. ububanzi Blade ka 4.25 m futhi ukuphakama -. 1.85 m kuphakamisa ngaphezulu eliphansi kungaba ezingeni ukuphakama hhayi ngaphezulu kuka 1.43 m, futhi inciphise -. Ngokwezinga ka 0.33 m ukufakwa Bulldozer ukujula senziwa metal eziqinile, ngaleso sizathu wakwazi ukukhonza isikhathi eside kakhulu. isisindo sakhe kwaba 5 wamathani. Kepha ukudabuka imishini, kwathiwa emelelwa nezinyo elilodwa nje vo. engela Ukuxega ungashintshwa 45 degrees. I sokungena ukujula ibihamba 1.2 amamitha. ukufakwa Rippers esingamathani angaba 3.5.

isevisi

Ngenxa uhlobo umzimba bonneted ukufinyelela izinhlelo eyinhloko ugandaganda akuzange kumenze noma ibuphi ubunzima. Zonke izinto babe high kakhulu futhi ube nesilinganiso esikhulu ukuphepha, ngakho isidingo ukulungiswa njalo akuzange kwenzeke. Nge efanele yesondlo inqubo wayegila aphume ngokushelela iminyaka eminingi nokuzinikezela egcwele. Futhi uma umonakalo ukulungisa akunzima, kusukela emshinini kwaba kudivayisi kahle elula.

Inkinga nje ukuthi angabangela nobunzima - ukudluliswa engesiyo. Too eyinkimbinkimbi ke Kwahlelwa. Zonke ezinye izinto kwanoma iyiphi umakhenikha ungase ukukulungisa, basebenzisa amathekhiniki imfundo manual. Det-250 izingxenye ezisele wayengasenakungena inkinga ukuthenga kusuka umthengisi ogunyaziwe.

isiphetho

Namuhla sithola ukwazi izici det-250 tractor. Izithombe kule moto ubukeka ngempela ithangi, kodwa umbala ophuzi kanye namafasitela amakhulu ukunikeza kungokwalabo ubuchwepheshe yezolimo. Ngesikhathi kokuhlinzwa, iyunithi kwakumelwe azibonakalise ngokwaso njengoba umsizi okuthembekile futhi enamandla kakhulu. Namuhla, intengo ku ezahlukene ayizinkulungwane 40-50 zamadola. It kuncike hlobo ugandaganda ukulungiswa kanye nemishini eyengeziwe efakwe kulo.
