Kazhinji yakavhurika hydraulic system inodzosera solenoid vharafu SV-08

Izvo zvikamu zviri nyore kugadzira ruzha mumidziyo ye hydraulic zvinowanzoonekwa sepombi nemavharuvhu, uye mavharuvhu ndiwo anonyanya kufashukira mavharuvhu uye emagetsi anotungamira mavharuvhu. Pane zvinhu zvakawanda zvinounza ruzha. Kune marudzi maviri eruzha rwevhavha yekufashukira: velocity ruzha uye mechanic ruzha. Ruzha rwevelocity ruzha rwunonyanya kukonzerwa nemafuta vibration, cavitation uye hydraulic impact. Mechanical ruzha runonyanya kukonzerwa nekukanganisa uye kukwesha kwezvikamu muvharuvhu.

(1) Ruzha runokonzerwa nedzvinyiriro isina kuenzana

Chikamu chevhavha yepilot yepilot relief valve chikamu chiri nyore-ku-vibrate sezvinoratidzwa muMufananidzo 3. Kana ichipfachukira pasi pekumanikidzwa kukuru, kuvhura kweaxial yevhavha yekufambisa idiki, chete 0.003 ~ 0.006 cm. Nzvimbo inoyerera iduku kwazvo, uye kuyerera kwevelocity kwakakwirira kwazvo, iyo inogona kusvika 200m / s, iyo inokonzera nyore nyore kusaenzana kwekumanikidza kuparadzirwa, kusaenzana kwemasimba emagetsi evhavha yekoni uye vibration. Uye zvakare, iyo ellipality inokonzerwa nekugadziriswa kwevharuvhu yekoni uye chigaro chevharuvhu yekoni, iyo tsvina inonamira yevhavhavhavha port uye deformation yekumanikidza inodzora chitubu kuchakonzerawo kuzunguzika kwevhavhavhavha. Nokudaro, zvinowanzoonekwa kuti vheji yekufambisa ndiyo inokonzera ruzha rweruzha.

Nekuda kwekuvapo kweiyo elastic element (spring) uye inofamba misa (cone valve), inoumba mamiriro ekuti oscillation, uye mhango yepamberi yevhavhavhavha inoita senge resonant cavity, saka kudengenyeka kwevharuvhu iri nyore kukonzera. iyo resonance yevharuvhu yose uye kuita ruzha, iyo inowanzoperekedzwa nechisimba chakasimba kusvetuka.
