Mugihe cyo gusana itsinda rya piston ya moteri, ingorane zivuka mugushiraho piston - impeta ziva mumashanyarazi ntizemerera piston kwinjira mubusa.Kugira ngo iki kibazo gikemuke, mandel ya piston ikoreshwa - wige ibi bikoresho, ubwoko bwabyo, igishushanyo mbonera hamwe nibisabwa kuva mu ngingo.
Intego ya piston impeta
Mandel yimpeta ya piston (crimping) nigikoresho muburyo bwa kaseti hamwe na clamp yagenewe kurohama impeta ya piston mumashanyarazi ya piston mugihe yashizwe mumashanyarazi.
Gusana itsinda rya piston ya moteri ntibikunze kurangira udakuye piston kumurongo.Kwishyiriraho nyuma ya piston muri silinderi yo guhagarika akenshi bitera ibibazo: impeta zashyizwe mumashanyarazi zisohoka hejuru ya piston kandi ikabuza kwinjira mukiboko.Kugira ngo iki kibazo gikemuke, mugihe cyo gusana moteri, ibikoresho bidasanzwe birakoreshwa - mandrele cyangwa impeta zimpeta za piston.
Mandel yimpeta ya piston ifite umurimo umwe wingenzi: ikoreshwa mukunyunyuza impeta no kurohama mumashanyarazi ya piston kuburyo sisitemu yose yinjira mubusa muri silinderi ya blok.Nanone, mandel ikora nkuyobora mugihe ushyira piston, ikayirinda kunyerera, kimwe no kwirinda kwangirika kwimpeta nindorerwamo ya silinderi.
Mandel yimpeta ya piston nigikoresho cyoroshye ariko gikomeye cyane, bitabaye ibyo ntibishoboka gusana itsinda rya piston hamwe nubundi buryo bwa moteri.Ariko mbere yuko ujya mububiko bwa mandel, ugomba gusobanukirwa ubwoko buriho bwibikoresho, imiterere yabyo.
Ubwoko, igishushanyo nihame ryimikorere ya piston impeta
Ibihe byuyu munsi birashobora kugabanywamo amatsinda abiri manini ukurikije ihame ryimikorere:
Atch Ikigereranyo (hamwe nuburyo bwo kugereranya);
Lever.
Bafite ibishushanyo mbonera bitandukanye kandi nihame ritandukanye ryimikorere.
Ratchet mandrels yimpeta ya piston
Ibi bikoresho ni ubwoko bubiri bwingenzi:
- Nuburyo bwa ratchet butwarwa nurufunguzo (cola);
- Hamwe nimikorere ya ratchet yinjijwe mumashanyarazi.
Byakoreshejwe cyane ni crimps yubwoko bwa mbere.Zigizwe n'ibice bibiri by'ingenzi: umukandara w'icyuma ucuramye hamwe na ratchet (ratchet).Ishingiro ryigikoresho ni kaseti ifite ubugari bwa milimetero mirongo kugeza kuri mm 100 cyangwa zirenga.Kaseti ikozwe mu byuma, irashobora kuvurwa ubushyuhe kugirango yongere imbaraga, izunguruka mu mpeta.Hejuru ya kaseti ni uburyo bwa ratchet hamwe nimyenda ibiri ifunganye.Ku murongo wuburyo hariho ingoma za kaseti zizunguruka hamwe ninziga ya gare hamwe na pawl yuzuye isoko.Ikariso ikozwe muburyo bwa leveri ntoya, iyo ikanda, uburyo bwa ratchet burarekurwa hanyuma kaseti ikarekurwa.Muri imwe mu ngoma za kaseti, hakozwe umwobo wa axial ya kwambukiranya kare, ushyizwemo umugozi wa L (collar) ushyizweho kugirango ushimangire kaseti.
Hariho ubwoko butandukanye bwimikandara ya ratchet yo gukorana na piston z'uburebure bunini - zifite uburyo bwa ratchet ebyiri (ariko, nkuko bisanzwe, hamwe ninziga imwe gusa hamwe na pawl) itwarwa numuyoboro umwe.Uburebure bwiki gikoresho bushobora kugera kuri mm 150 cyangwa zirenga.
Ibyo ari byo byose, mandel zubu bwoko, bitewe nigishushanyo cyazo, ni rusange, inyinshi murizo zigufasha gukorana na piston ifite diameter ya mm 50 kugeza 175, kandi na mandel ya diameter yiyongereye nayo irakoreshwa.
Ikariso ya ratchet yimpeta ya piston ikora muburyo bworoshye: mugihe umurongo wa ratchet uhinduwe na cola, uruziga rw'ibikoresho ruzunguruka, hamwe na pawl isimbuka ubusa.Iyo uhagaze, umukufi wa pawl uhagarara ku menyo yinziga kandi bikayirinda gusubira inyuma - ibi bituma ikosora rya mandel kandi, bityo, gutondekanya impeta mu mwobo wacyo.
Kunyunyuza imitsi yubatswe muburyo bwa ratchet yubatswe ifite ibikoresho bisa, ariko ntibifite umukufi - uruhare rwayo ikinishwa na lever yubatswe.Mubisanzwe, ibikoresho nkibi bifite umukandara muto, byashizweho kugirango bikore hamwe na moto nibindi bikoresho bito bito.
Mandrel ya piston impeta ifite urufunguzo (wrench)
Ratchet piston impeta ya mandel
Lever mandrels yimpeta ya piston
Ape Kaseti hamwe na pompe cyangwa ibindi bikoresho;
● Amashusho yerekana hamwe nigikoresho kidasanzwe - amatiku, harimo na ratchet;
Ape Amashusho yerekana hamwe na lever yubatswe hamwe nuburyo bwo gufunga hamwe nubushobozi bwo guhuza na diameter ya piston.
Byoroheje cyane guhondagura muburyo bwa mbere ni: mubisanzwe izi nimpeta zifunguye zikozwe mubyuma bisa cyane bifite impande ebyiri cyangwa izunguruka kumpande zombi, zikazanwa hamwe na pliers cyangwa pliers.Mandel nkiyi ntisanzwe, irashobora gukoreshwa gusa na piston ya diametre imwe, kandi byongeye, ntabwo byoroshye kuyikoresha, kubera ko isaba kugumana buri gihe pliers cyangwa pliers kugeza piston yashizwe mumaboko.
Mandrels yubwoko bwa kabiri iratunganijwe neza, nayo ikozwe muburyo bwimpeta zifunguye, icyakora, pliers zidasanzwe zikoreshwa kuri screed zabo hamwe nibishoboka byo gukosora mumwanya runaka.Ibintu nkibi ntibisaba gukoresha imbaraga buri gihe kuri mite, kubwibyo biroroshye kandi byoroshye gukoresha.Mubisanzwe, ibikoresho byubu bwoko bitangwa muburyo bwibikoresho hamwe na mandel nyinshi za diameter zitandukanye.
Lever piston impeta ya mandel
Guhitamo neza no gukoresha piston impeta ya mandel
Guhitamo piston impeta ya piston igomba gukorwa hashingiwe kubiranga piston nakazi kagomba gukorwa.Niba imodoka imwe gusa irimo gusanwa, birumvikana rero guhitamo guhuzagurika byoroshye hamwe na ratchet cyangwa se hamwe na clavier.Niba kwishyiriraho piston bikorwa buri gihe (kurugero, mumaduka yo gusana imodoka), nibyiza rero guhitamo icyerekezo kimwe cyumukandara wumukandara hamwe nuburyo bwa ratchet cyangwa urutonde rwa mandre ya diametre zitandukanye.Byakagombye kumvikana ko kuri piston nini yimodoka nibyiza gukoresha mandel yagutse, no kuri piston ya moto - ifunganye.
Kugura kugirango ukoreshe umwuga, ibikoresho byuzuye byo gusana amatsinda ya piston birashobora kuba amahitamo ashimishije.Ibikoresho nkibi birashobora kuba birimo mandrale zitandukanye kumpeta ya piston (kaseti na kaseti ya ratchet), impeta zimpeta nibindi bikoresho.
Gukorana na mandel yimpeta ya piston mubisanzwe biroroshye, biza mubikorwa byinshi:
● Kugira ngo byorohereze, shyira piston muburyo bubi, usige amavuta ya groove hamwe nimpeta hamwe nijipo neza hamwe namavuta;
● Shyira impeta muri ruhago ukurikije ibyifuzo - kugirango ibice byabo bifunga biri hagati ya dogere 120 na mugenzi wawe;
Gusiga amavuta yimbere ya mandrale hamwe namavuta;
Shyira mandel kuri piston;
● Ukoresheje umugozi, lever cyangwa pliers (ukurikije ubwoko bwibikoresho), komeza mandel kuri piston;
● Shyira piston hamwe na mandel muri silinderi yo guhagarika, koresha mallet cyangwa inyundo unyuze mu gaseke kugirango ukure piston witonze muri mandel muri silinderi;
● Nyuma yuko piston imaze kwinjizwa muri silinderi, kura no kurekura mandel.
Gushiraho piston impeta
Mugihe ukorana na mandel, birakenewe gukomera neza: niba gutembagaza ari intege nke cyane, impeta ntizinjira mumashanyarazi kandi bizabangamira ishyirwaho rya piston mumurongo;Hamwe no gukabya gukabije, piston bizagorana gukuramo manda, kandi muriki gihe, uburyo bwigikoresho bushobora gucika.
Hamwe noguhitamo neza no gukoresha mandel ya piston, guteranya moteri nyuma yo gusana itsinda rya piston bizakenera igihe gito nimbaraga.
