Ongororo yekuti sei jekiseni muromo wakanamira mumajekiseni.(Chikamu 1)

1 Kusimbiswa kwezvinhu zvekuedza

Kuburikidza nekuongororwa kwezvikonzero zvinogoneka zvekunamira kweiyo nozzle tsono yevharuvhu musangano, zvakasarudzwa kuita nhevedzano yekuongorora uye ongororo pane yakashata nozzle musangano.Zvinhu zvekuongorora zvakananga ndezvizvi:

1) Tarisa kuenderana kubvumidzwa kwekubatanidza uye kukwana kweiyo tsono valve chigaro chechigaro;

2) Dzokorora kutenderera, cylindricity, roughness, uye kuoma kwepamusoro kwevhavha yetsono mushure mekuchenesa (kubvisa pamusoro pevhu, nezvimwewo);

3) Kuchenesa (kubvisa ngura yepamusoro, nezvimwewo)

4) Dhonza vharuvhu yetsono uye nozzle, uye ita ongororo yemavara pane iyo mating pamusoro pevharuvhu yetsono uye nozzle;

5) Tumira vharuvhu yetsono uye nozzle ye metallographic inspection, kuyera Kusachena ratio.

2 mhinduro dzebvunzo
2.1 Mhedzisiro yekuyerwa kwedhayamita yekunze yevhavha yetsono inokodzera nzvimbo uye dhayamita yemukati yehuputi inoratidzwa muTebhurari 1. Pakati pavo, kunyange zvikamu zvine chitambi nhamba yeHHM hazvina kuiswa uye kushanda.Kubva pachiyero che data, zvinogona kuoneka kuti mapeji akakodzera emaseti maviri ekubatanidza akakura kupfuura kukosha kwedhizaini, kutenderera kwegomba remukati revharuvhu yetsono uye muromo une nhamba yechitambi HD zvese zvinosangana nezvinodiwa zvekugadzira, uye kutenderera kwegomba remukati revharuvhu yetsono uye muromo une nhamba yechitambi HHM inodarika dhizaini Inodei.Nzvimbo yepamusoro yevhavhavha yetsono ine nhamba yesimbi yesimbi HD yakanyanyisa, uye nzvimbo yakakodzera haigoni kuongororwa.Mamiriro ezvinhu chaiwo anoratidzwa muFigure2.

Nzvimbo yakakodzera yevhavha yetsono ine nhamba yesimbi yesimbi HHM yakakura, ine bandwidth inenge 2mm, sezvinoratidzwa muMufananidzo 3 (nzvimbo yekubatanidza ichava yakasviba mushure mokunge vaviri vacho vari pasi zvishoma, saka unogona kutarisa mamiriro akakodzera).Mukuwedzera, kona yekoni kumucheto wepamberi wevhavha yetsono inoyerwa, uye dhizaini inoda kona ye91 ° ± 5'.Kona yetsono yenhamba yesimbi yechisimbiso inotanga HHM i91 ° 1′, uye kona yevharuvhu yetsono yenhamba yechitambi chesimbi inotangira HD i91 ° 2′, zvese zvinosangana nezvinodiwa zvekudhirowa.
