Valve Springs: Iwo Magamba Asina Kusukwa eInjini Kuita

Paunenge uchitaura nezve injini uye kuita kwayo, kune akati wandei anouya mupfungwa - mapistoni, macylinders, camshafts uye turbocharger kutaura zvishoma.Nekudaro, pane chimwe chinhu chakakosha chinowanzo furatirwa asi chinoita basa rakakosha mukuchengeta injini yako ichimhanya nemazvo uye nekuwedzera simba rekubuda kwemagetsi: zvitubu zvevharuvhu.Muchinyorwa chino, tinonyura munyika yezvitubu zvevharuvhu, tichikurukura nezvebasa ravo, mhando, uye kukosha kune yakazara injini kuita.

Kuti unzwisise kukosha kwezvitubu zvevharuvhu, unofanirwa kutanga wanzwisisa basa ravo mune injini yekupisa mukati.Zvitubu zvevharuvhu zvinogara pakati pemusoro wecylinder uye mavharuvhu uye vane basa rekuona kuti mavharuvhu einjini anovhara nemazvo mushure mekutora kwega kwega uye kupera simba.Vanoita sezvitubu zvemagetsi, vachishandisa simba kune valve, zvichiita kuti ivhure uye ivhare panguva yakakodzera.

Rimwe remabasa makuru ezvitubu zvevhavha ndeyekuchengetedza nguva dzose kudzvinyirira pamavharuvhu.Iyi dzvinyiriro inofanirwa kuve nechokwadi chekuisa chisimbiso chakakodzera pakati pevharuvhu nechigaro, kudzivirira magasi anopisa kubva pakupukunyuka.Pasina kukwana kwechitubu kumanikidzwa, vharuvhu inogona kusavhara zvachose, zvichikonzera kurasikirwa kwekumanikidza, kuderedzwa kwesimba, uye inogona kukanganisa injini.Uye zvakare, zvitubu zvevharuvhu zvinobatsira kubata kuvhunduka uye kudengenyeka kunokonzerwa nechitima chevhavha, kuve nechokwadi chekushanda kweinjini.

Zvitubu zvevharuvhu zvinouya mumhando dzakasiyana siyana uye magadzirirwo kuti aenderane neakasiyana injini yekushandisa.Mhando dzinonyanyozivikanwa dzinosanganisira zvitubu zvecoil, zvitubu zvakapetwa kaviri, zvitubu zvehuchi, uye zvitubu zveconical.Coil zvitubu, sekureva kunoita zita, zvitubu zvehelical izvo zvinopa kusimba kwakasarudzika uye zvinopa kusagadzikana kunogara muhupenyu hwavo hwesevhisi.Zvitubu zviviri, kune rumwe rutivi, zvine zvitubu zviviri zvakadzika, apo chitubu chekunze chinotsigira chitubu chemukati, nekudaro chinowedzera kugadzikana kwevharuvhu pakumhanya kukuru kweinjini.

Zvitubu zvenyuchi zvinoratidzwa nechimiro chadzo checonical chakafanana nemukoko wenyuchi.Aya matubu epamusoro ane dhayamita yakakura, zvichibatsira kuderedza huremu hwese hwevhavhatrain.Yayo yakasarudzika dhizaini inobvumira zviri nani kudzora vharafu uye yakakwirira injini kumhanya.Zvitubu zvekoni, sekureva kunoita zita, zvine chimiro chakafanana nekoni ine imwe magumo idiki pane imwe.Iyi dhizaini inobatsira kugovera kushushikana zvakaenzana muchirimo, kuve nechokwadi chekugara kwenguva refu uye kuita.

Nepo zvitubu zvevharuvhu zvakaringana nemamiriro ekutyaira nguva dzose, vanofarira mashandiro vanowanzo sarudza zvitubu zvevharuvhu yemashure kuti vawedzere kushanda kweinjini dzavo.Zvitubu zvevharuvhu zvakakwidziridzwa zvinopa mwero wechirimo wepamusoro wekumhanya kweinjini pasina kuyerera kwevharuvhu.Kuyangarara kwevharuvhu kunoitika kana zvitubu zvisingakwanisi kuenderana nekamshaft inokurumidza kutenderera, zvichiita kuti mavharuvhu arove mapistoni, zvichikonzera kutadza kweinjini.

Yakakwidziridzwa mavharuvhu zvitubu zvakare inovandudza kugadzikana kwevharuvhu, kunyanya mumainjini ane hukasha camshafts uye yakakwirira kusimudza.Iyo yakawedzera kudzvanywa kwechitubu inobatsira kuchengetedza kwakaringana kudzora kwevhavha uye inoderedza mukana wevhavha bounce - mamiriro ayo iyo valve haina kuvhara zvizere nekuda kwekumhanya kweinjini.Nekudzora kurinani uye kushomeka kwevharuvhu, injini inogona kuburitsa simba rakawanda uye torque mukati meiyo rev rev.

Zvinofanira kuonekwa kuti kusarudzwa kwezvitubu zvevhavha kunofanira kunyatsotariswa maererano nezvinodiwa zvejini.Zvinhu zvakadai se camshaft profile, chinangwa chekushandiswa (kutyaira mumigwagwa kana mujaho) uye inodiwa magetsi anobuda zvinofanirwa kutariswa.Kuisa zvitubu zvevharuvhu zvine mwero wechirimo wakanyanya kukwirira kunogona kukonzera kupera nguva isati yasvika kune zvikamu zvechitima chevhavha, nepo kushandisa zvitubu zvakaderera zvakanyanya zvinogona kukonzera kutenderera kwevhavha uye kukanganisa kushanda.

Kugara uchiongorora uye kuchengetedza mavharuvhu zvitubu zvakakoshawo kuhupenyu hweinjini uye kuvimbika.Nokufamba kwenguva, zvitubu zvevharuvhu zvinogona kuneta, kurasikirwa nekunetseka uye kushanda zvakanaka.Zvinokurudzirwa kutsiva zvitubu zvevhavha nguva nenguva kana kana zviratidzo zvekupfeka kana kukuvadzwa zvichionekwa.Pamusoro pezvo, kuve nechokwadi chekuzora kwakakodzera kwezvikamu zvechitima chevharuvhu kwakakosha kudzikisa kupokana uye kugadzirwa kwekupisa, nekudaro kuwedzera hupenyu hwese hwezvitubu zvevharuvhu.

Mukupedzisa, nepo zvitubu zvevharuvhu zvingasagamuchira kutariswa kwakafanana nekuzivikanwa sezvimwe zvikamu zveinjini, basa ravo mukuita kweinjini harigone kurerutswa.Zvitubu zvevharuvhu zvinoita basa rakakosha mukukwidziridza kubuda kwemagetsi uye kuchengetedza kusimba kweinjini sevachengeti vekutonga kwevharuvhu uye kuve nechokwadi chekuisa chisimbiso chakakodzera.Kunyangwe kuburikidza neakasiyana magadzirirwo kana kugona kwavo kubata yakawedzera mwero wechirimo, zvitubu zvevharuvhu zvinopa mupiro wakakura pakuita kwese kweinjini.Saka nguva inotevera paunenge uchiyemura injini inoita zvemhando yepamusoro, rangarira magamba asina kuimba ari kushanda nesimba kuseri kwezviitiko, zvitubu zvevharuvhu.
