Serva valaSM4-440 (40) 151-80 / 40-10-s205 ndi gawo la oyang'anira mafuta mu dongosolo la mafuta mu eya. Imalumikizana ndi zowongolera zamagalimoto ndi kutali, ndipo zimaphatikizana ndi zamagetsi ndi ma hydraulic dongosolo.

Pamene serwa valavu SM4-40 (40) 151-80 / 40-10-s205 ilibe chizindikiro chapakatikati, boffle imayikidwa pakati ndipo pl ndi yofanana ndi zero. Chizindikiro cha magetsi chikalowetsa mota la torque kuti muchepetse vutoli ndi kusintha kwa valavu. Mafuta akamayenda, chizindikiro cha LVDT chimakonda kukhala chogwirizana ndi Valavu Lamulo la Lamulo. Pakadali pano, zomwe zikuchitika panokha pa torque, bofle imabweranso kwa malo apakati pazinthu zonse ziwiri, ndipo valavu yosiyanasiyana pamapeto a singano yoyambirira yomwe ili ndi vuto linalo.

Kugwiritsa ntchito kwakukulu kwa servo valavu SM4-40 (40) 151-80 / 40-10-s205 imaphatikizaponso izi:

1. Magwiridwe okhazikika: Ntchito yokhazikika ya servo valavu imatanthawuza kugwirira ntchito kwina, mphamvu ya servo imatha kuwongolera mayendedwe ake, kukakamizidwa ndi kuwongolera dongosolo la hydralic kuti likwaniritse ntchito yokhazikika ya dongosololi.

2. Ntchito yovuta: Kugwirira ntchito mosamala kwa servo kumatanthauza kuti serva valve imatha kuyankha mwachangu komanso molondola kuti musinthe munthawi ya madongosolo enieni.

3. Kugwiritsa ntchito modalirika: Ntchito yodalirika yodalirika imatanthawuza kuti serva valale imatha kukhala yogwira ntchito popanda kulephera kapena kulonda panthawi yogwiritsa ntchito nthawi yayitali.

4. Kusintha: Kusintha kwa ma valve vumba kumatanthauza kuti valve valavu amatha kusintha madera osiyanasiyana ogwira ntchito ndi zochitika zogwira ntchito kuti akwaniritse zosowa zosiyanasiyana.

5. Kulondola kwa chizolowezi: Kuchita bwino kwa servo valve kumatanthauza kulondola komwe servo imatha kuwongolera magawo, kukakamizidwa, ndi kuwongolera munthawi yazomwe zimathandizira.

Serva valaSM4-440 (40) 151-80 / 40-10-S205 imapereka dongosolo lolowera ndi ma curve obwereza olondola, ndikusintha kwamphamvu kapena kudzipereka. Ndikukakamizidwa mpaka 350bar, malo ogwiritsira ntchito a SMM a SM4 a SME akhoza kupereka zotulutsa zosiyanasiyana. Valavu pakati pa valavu ya valavu imapangidwa ndi chitsulo chosapanga dzimbiri kuti muchepetse kuvala ndi kuvunda. Mphete yokhazikitsidwa pa valve stavavu imalepheretsa valavu pakati pa kulanda ndikuwonetsa bwino ntchito ya unit.
