Michina yekuvaka XDYF20-01 mutyairi wekuyamura vharafu

Voltage regulation failure

Iyo yekumanikidza inodzora kutadza dzimwe nguva inoitika mukushandiswa kwevhavha yekufashukira. Pane zviitiko zviviri zvekumanikidzika kwekugadzirisa kukundikana kwevhavha yekuyamura mutyairi: imwe ndeyokuti kudzvinyirira hakugoni kusimbiswa nekugadzirisa kudzvinyirira kudzora handwheel, kana kudzvinyirira hakugoni kusvika kune yakarongwa; Imwe nzira ndeyekugadzirisa handwheel pressure pasina kudonha, kana kutowedzera kudzvanya nguva dzose. Pane zvimwe zvikonzero zvekutadza kwekudzora kudzvanywa, kunze kweiyo radial clamping yepakati pevhavha nekuda kwezvikonzero zvakasiyana:

Kutanga, damper yemuviri mukuru wevhavhavha (2) yakavharwa, uye kumanikidzwa kwemafuta hakugone kuendeswa kukamuri yepamusoro yevhavha huru uye kamuri yepamberi yevhavhavhavhavha, kuitira kuti vheji yevatyairi irasikirwe nebasa rayo rekutonga. kumanikidzwa kwevhavha huru. Nekuda kwekuti hapana kudzvanywa kwemafuta mukamuri repamusoro revharuvhu uye simba rechitubu rakanyanya kudiki, iyo huruvhavha inova yakananga-inoita yekuyamura vharafu ine simba diki rechirimo. Kana kudzvinyirirwa mukamuri yekupinza mafuta kwakadzikira, vheji huru inovhura vharafu yekuyamura uye sisitimu haigone kugadzira kumanikidza.

Chikonzero nei dzvinyiriro isingakwanisi kusvika kune yakarongerwa kukosha ndeyekuti iyo yekumanikidza inodzora chitubu yakaremara kana kusarudzwa zvisizvo, iyo yekumanikidza sitiroko yekumanikidza inodzora chitubu haina kukwana, kubuda kwemukati kwevharuvhu kwakakurisa, kana cone valve. yevharuvhu yepilot yakapfekwa zvakanyanya.

Chechipiri, damper (3) yakavharwa, kuitira kuti mafuta emafuta arege kuendeswa kuvhavha yekoni, uye pilot valve inorasikirwa nebasa rekugadzirisa kudzvinyirira kwevhavha huru. Mushure mokunge damper (orifice) yakavharwa, vheji yekoni haizozaruri mafuta anoputika pasi pekumanikidzwa kupi zvako, uye hapana mafuta anoyerera muvhavha nguva dzose. Kudzvinyirirwa mumakamuri epamusoro nepamusoro evhavha huru nguva dzose yakaenzana. Nemhaka yokuti annular inotakura nzvimbo pamucheto wepamusoro wevhavha huru yevhavha yakakura kudarika iyo pamucheto wakadzika, iyo huruvhavha inogara yakavharwa uye haingapfuuri, uye kudzvinyirira kwevhavha huru kuchawedzera nekuwedzera kwemutoro. Kana iyo actuator ikamira kushanda, iyo system pressure inowedzera nekusingaperi. Pamusoro pezvikonzero izvi, zvichiri kudikanwa kuti utarise kana chiteshi chekunze chekutonga chakavharwa uye kana iyo cone valve yakaiswa zvakanaka.
