Excavator accessories SK200-5 excavator huru yekudzivirira vharafu YN22V00002F1

Mukugadzirwa kwemazuva ese ekuvaka, yekuchera muchina wekuvaka unowanzo shandiswa, unoshandiswa zvakanyanya mukucherwa kwenheyo yezvivakwa zvedzimba uye kuchenesa mushure mekupedzwa, kuiswa kwepombi yemadhorobha, kuvakwa kwekuchengetedza mvura yepurazi uye zvimwe zviitiko, zvine zvakanakira kuvaka kuchinjika uye yakakwirira. kunyatsoshanda. Excavator inowanzo umbwa nechishandiso chekushanda, chigadziri chinotenderera, cab, chigadziro chekufamba uye hydraulic control system, iyo isingadzivisiki mu hydraulic control system kushandisa valve yekuyamura, valve yekuyamura mu hydraulic system inonyanya kuita basa rekugara kudzvinyirira kuputika uye. kuchengetedzwa kwekuchengetedza. Parizvino, vheji yekuyamura inoshandiswa mukuchera ivhavha yekuyamura mutyairi, sezvakaratidzwa muMufananidzo 1 uye Mufananidzo 2. Inonyanya kuumbwa nekusimudza musoro 1, main valve core 2, main valve sleeve 3, pilot valve core 4, pressure inodzora chitubu. 5 uye sleeve yevhavha yevatyairi 6. Musoro unosimudza, sleeve huru yevharuvhu uye sleeve yevhavha yepilot inopiwa nemakomba, uye mafuta ekumanikidza anopinda mukati memukati wevhavha huru kuburikidza negomba rinonyorovesa remusoro unosimudza uye rinoita papilot valve core. Kana iyo system yekumanikidza iri pasi pekutanga kudzvanywa kwekutanga pilot spool, vheji yekufambisa iri munzvimbo yakavharwa, uye mukati nekunze kumanikidzwa kweiyo huru spool yakaenzana. Nekuda kwekusiyana kwemukati nekunze nzvimbo, iyo huru spool inoramba yakavharwa pasi pechiito chekumanikidza kwemvura; Kana simba rehurongwa richinge rakakura kudarika kuvhurika kwevharuvhu spool, pilot valve spool inosairirwa kure nemafuta ekumanikidza, uye mafuta ekumanikidza anoyerera achidzokera kutangi kuburikidza nepilot valve sleeve hole uye guru revhavha sleeve buri. Panguva ino, kudonha kwekumanikidza kunogadzirwa kana mvura ichiyerera nepagomba rekunyorovesa remusoro wekusimudza, kuitira kuti kudzvanywa kwemukati weiyo master valve spool yakakura kupfuura yekunze kamuri yekumanikidza, iyo inosundira main valve spool kuvhura, uye oiri yehydraulic inoyerera ichidzokera kutangi kuburikidza negomba guru revharuvhu. Kana iyo system yekumanikidza inodonha kusvika kudiki pane yekuvhura kudzvanywa kwepilot spool, pilot spool inovhara, uye kana mutsauko wekumanikidza pakati pemukati nekunze kweiyo huru spool idiki, kuvhura kunovharwa pasi pechiito chekugadzirisa chitubu. Zvisinei, mukushandiswa kwechokwadi, zvinowanikwa kuti kana vheji yekuyamura iri pamusoro ichishandiswa, pilot valve core inoda kuzarura uye kuvhara nguva dzose, uye kuzarura nekuvhara kushanda kwevhavha yekufambisa kunogadzirisa kushanda kwevhavha yekuyamura, saka chikamu. yegomba revharuvhu remutyairi rakasangana nepilot valve core cone yakakosha. Kuti uve nechokwadi chekugadzikana kwekushanda kwevhavha yekuyamura, nzvimbo yevhavha yevhavha yevatyairi inowanzoda yakakwirira machining accuracy. Iyo pilot valve sleeve hole yakareba, mutyairi wevhavhavhavha munzvimbo yekugadzirisa uye kuongororwa zvakanyanya kuoma, kugadzirisa kunyatsoita kwakaoma kuve nechokwadi, zvichiita kuti kushanda kwevhavha yekufambisa hakugone kuvimbiswa zvinobudirira, kugadzikana kwevhavha yekuyamura kwakanyanya. yakakanganiswa, uyezve, iyo huru yevharuvhu yepakati uye huru yevharuvha sleeve pakati peiyo coaxiality inonyanya kuvimba nepilot valve sleeve screw positioning kuti ive nechokwadi, nekuti sleeve yevharuvhu yevatyairi yakareba, Kutsauka kudiki kwekumisikidza tambo kuchakanganisawo kukwana kweiyo. main spool uye sleeve huru yevharuvhu, zvichikonzera kusavhara zvakanaka uye kudonha.
