1. Isimiso Sokusebenza

Iphampu kawoyela yegiya iqukethe shaft yokushayela, igiya lokushayela, i-shaft eshayelwa, igiya elishayelwa, indlu, njll. Amagiya amabili anenani elifanayo lemeshi yamazinyo elinye nelinye futhi afakwe endlini. I-radial and end surface clearances phakathi kwamagiya nendlu mancane kakhulu. Kunezimbobo zikawoyela kanye nezindawo zokukhipha uwoyela endlini. I-shaft yokushayela ifakwe egiyeni lokushayela, kanti igiya elishayelayo lifakwe imikhono evulekile ku-shaft oshayelayo. Lapho injini kadizili isebenza, igiya le-helical ku-crankshaft lishayela igiya lokudlulisela empompini kawoyela ukuze lijikeleze, futhi igiya lokushayela elisendlini yepompo likawoyela lishayela igiya elishayelwa ukuzungeza. Amagiya amabili azungeza ezinhlangothini eziphambene, futhi uwoyela uhamba phakathi kwamazinyo futhi ugeleze usuka endaweni yokufaka uwoyela uye endaweni yokukhipha uwoyela. Ngakolunye uhlangothi lwegumbi lokungena likawoyela, ngenxa yokungaxutshwa kwamagiya nokususwa okuqhubekayo kwamafutha, kukhiqizwa i-vacuum ukuze yakhe umfutho ophansi futhi ikhiqize ukumuncwa, ukuze amafutha epanini likawoyela angene ekamelweni lokungena likawoyela. ngokusebenzisa isihlungi ngaphansi kwesenzo sokucindezela komkhathi, futhi ngakolunye uhlangothi lwegumbi lokuphuma likawoyela, ngenxa yokuhlangana kwamagiya nokususwa okuqhubekayo kukawoyela, ingcindezi kawoyela iyanda, futhi amafutha akhishwa ngokucindezela okuthile futhi acindezelwe ezindaweni ezingqubuzanayo zengxenye ngayinye ehambayo.

Ngaphezu kwalokho, ekugcineni kwe-meshing yamagiya amabili, ngenxa yokuba khona kwamafutha anengcindezi ephezulu kanye negebe elincane phakathi kobuso bokuphela kwegiya nendlu, uwoyela akulula ukuvuza, okwandisa ingcindezi ku-shaft yegiya. , ngaleyo ndlela kubhebhethekise ukuguga kwe-shaft kanye nomgodi. Ukuze kuqedwe lo mphumela, ukukhululeka kwengcindezi kuvame ukuvulwa kukhava yepompo ukuze kugeleze amafutha endaweni yokuphuma kawoyela eduze nokunciphisa ingcindezi ukuze kuzuzwe umphumela wokusiza ingcindezi. Ivolumu yokumpompa uwoyela kanye nomfutho kawoyela wepompo likawoyela kuyenyuka ngokunyuka kwesivinini senjini kadizili. I-valve yokukhulula umfutho kawoyela iqukethe i-valve noma ibhola kanye nesiphethu esivunguzayo. Amafutha adonswa ngesisefo futhi athunyelwe esihlungini samafutha. Lapho umfutho wokunikezwa kukawoyela ukhuphuka ngesivinini senjini ye-diesel, i-valve yokukhulula ingcindezi iyavuleka. Ngalesi sikhathi, amafutha angena ohlangothini lwe-inlet kusukela ohlangothini lwe-outlet ngokusebenzisa i-bypass ukuze alondoloze ingcindezi ecacisiwe.

2. Izici zesakhiwo

Isakhiwo esilula, usayizi omncane, isisindo esincane, kanye nokulethwa kwamafutha amakhulu. Iphampu ye-cycloid rotor yamukela ukwakheka kwe-rotor meshing yangaphakathi nangaphandle, enenani elincane lamazinyo nobukhulu besakhiwo esihlangene. Ingenza umgodi ovaliwe ngaphandle kosizo lwezinye izakhi zokuzihlukanisa, futhi inenani elincane lezingxenye.

3. Izici zokunyakaza

Ukusebenza okushelelayo nomsindo ophansi. Inombolo yamazinyo we-rotor yangaphakathi nangaphandle yepompo ye-cycloid rotor ihluka ngezinyo elilodwa kuphela. Uma zihamba ngokuhlobene, ijubane lokushelela lendawo yezinyo liphansi, futhi iphuzu lokuxhuma lihlala lihamba eduze kwephrofayili yezinyo le-rotor yangaphakathi nangaphandle. Ngakho-ke, ukuguga okuhambisanayo kwezindawo zamazinyo zama-rotor amabili kuncane. Njengoba i-engeli yemvilophu yegumbi lokudonsa uwoyela kanye negumbi lokukhipha uwoyela likhulu, elisondele ku-145 °, ukumunca uwoyela kanye nesikhathi sokukhipha sanele ngokwanele, ngakho ukugeleza kwamafutha kuzinzile, ukunyakaza kuzinzile, futhi umsindo ulungile. iphansi kakhulu kunaleyo yephampu yegiya.

4. Izici zesivinini esikhulu

Kumaphampu egiya angenayo involute evamile, uma isivinini siphezulu kakhulu, isigodi sezinyo sizogcwaliswa ngokungenele ngowoyela ngenxa yamandla e-centrifugal, enze "i-cavity", enciphisa ukusebenza kahle kwepompo. Ngakho-ke, ijubane layo akuvamile ukuba lidlule 3000rpm, futhi isivinini circumferential ingaphakathi 5-6m/s. Ngephampu ye-cycloid rotor, ububanzi be-engeli yokumunca kanye nokukhipha bukhulu. Uma ujikeleza ngesivinini esikhulu, amandla e-centrifugal ahambisana nokugcwaliswa kwamafutha esigodini sezinyo, futhi akukho mkhuba oyingozi "we-cavity" ozokwenzeka. Ngakho-ke, ububanzi besivinini sephampu ye-cycloid rotor ingaba kusuka kumakhulu ambalwa kuya cishe ekuguqukeni kwezinkulungwane eziyishumi.
