Ukulawula ukugeleza okulungisekayo ngokuzenzela i-hydraulic valve NV08

Izindaba zidinga ukunakwa

Njengoba umthamo wokugeleza uyancipha, isilinganiso esiguquguqukayo se-valve sizokwehla. Kodwa okungenani kungaqinisekiswa ukuthi kuphakathi kuka-10:l no-15:1. Uma isilinganiso esilungisekayo sisincane, kuzoba nzima ukulungisa ukugeleza.

Uma ama-valve esetshenziswa ochungechungeni, ngokushintsha kokuvula, umehluko wengcindezi phakathi kwangaphambili nangemuva kwama-valve nawo uyashintsha, okwenza ijika lesici esisebenzayo lama-valve liphambuke ezicini ezifanelekile. Uma ukumelana kwepayipi kukukhulu, umugqa uzoba isici sokuvula ngokushesha, futhi amandla okulungisa azolahleka. Izici zamaphesenti alinganayo zizoba izici zomugqa oqondile. Ngaphansi kwesimo sokugeleza okuncane, ngenxa yokuthi kunokumelana okuncane kwamapayipi, ukuhlanekezela kwezici ezingenhla akukukhulu, futhi isici sephesenti elilinganayo empeleni asikho isidingo. Ngokombono wokukhiqiza, lapho i-Cv =0.05 noma ngaphansi, akunakwenzeka ukukhiqiza amaphesenti alinganayo amajamo aseceleni. Ngakho-ke, inkinga eyinhloko yama-valve amancane okugeleza indlela yokulawula ukugeleza ngaphakathi kwebanga elidingekayo.

Ngokombono womphumela wezomnotho, abasebenzisi bathemba ukuthi i-valve ingasetshenziswa kokubili ukunqamula nokulawula, futhi kungenziwa. Kodwa nge-valve elawulayo, ngokuyinhloko ukulawula ukugeleza, futhi ukuvala kungokwesibili. Akulungile ukucabanga ukuthi ukugeleza kwe-valve encane yokugeleza ngokwayo kuncane kakhulu futhi kulula ukubona ukucasha lapho ivaliwe. Ukuvuza kwama-valve amancane okulawula ukugeleza ngokuvamile kulawulwa phesheya. Uma inani le-Cv lingu-10, ukuvuza kwevalvu kuchazwa ngokuthi 3.5 kg/cm. Ngaphansi kwengcindezi yomoya, ukuvuza kungaphansi kuka-1% wokugeleza okuphezulu.
