Chidule komanso mawonekedwe amagetsi oyendera

Chidule

Valavu yothamanga ndi valavu yomwe imadalira kusintha kusunthika kwamadzimadzi kwanyumbayo kuti izitha kuyendetsa kayendetsedwe kake pakasinthidwe kena kake, potero amasintha liwiro la oyendetsa (hydraulic silinda kapena ma hydraulic motor). Zimaphatikizira ma valve opumira, valavu yowongolera liwiro, valavu yampweya wopumira ndi valavu yosonkhanitsa. Fomu yoyikirayi ndiyokhazikitsidwa kopingasa. Njira yolumikizira imagawika mtundu wa flange ndi ulusi; mtundu kuwotcherera. Njira zowongolera ndi zosinthira zidagawika zokha komanso zowongolera.

Valavu yothamanga, yomwe imadziwikanso kuti 400X valve control, ndi valavu yamagetsi yomwe imagwiritsa ntchito njira yoyendetsa bwino kwambiri yoyendetsa mayendedwe.

1. Kusintha kwa njira yochepetsera malo am'madzi pogwiritsa ntchito mbale yolumikizira kapena valavu yokhotakhota, pogwiritsa ntchito mavavu oyendetsa ndege ofanana kuti achepetse kuwonongeka kwa mphamvu poyenda

2. Kuzindikira kwamphamvu, chitetezo ndi kudalirika, kusokoneza kosavuta komanso moyo wautali.

Valavu yothamanga imatha kukwanitsa kuyendetsa bwino dongosolo popanda magetsi akunja. Kuyenda kumakhala kocheperako pakusunga kusiyanasiyana kwamphamvu pakati chakutsogolo ndi kumbuyo kwa chimbudzi (kutsegula kosasunthika) kosasunthika, motero imatha kutchedwanso kuti valavu yokhazikika.

Cholinga cha valavu yoyenda mosadukiza ndikutuluka, komwe kumatha kutseka kuchuluka kwa madzi akuyenda kudzera mu valavu, osati kutsutsana. Amatha kuthana ndi vuto la kusalinganika kwamphamvu kwa dongosololi: kuti ntchito yokhazikika ya firiji imodzi, chowotcha, nsanja yozizira, chosinthira kutentha, ndi zina zitheke, ndikofunikira kuwongolera kuyenda kwa zida izi kuti zikonzeke mtengo wovoteledwa; kuchokera kumapeto kwa dongosololi, kuti mupewe Kugwirizana kwa kusintha kwamphamvu kumafunikanso kuchepetsa kuyendetsa kumapeto kwa chipangizo kapena nthambi.

Vuto lomwe liyenera kulipidwa pakupanga, kuwonongeka kwa valavu yowongolera ndikuti valavu ili ndi zosowa zochepa zogwirira ntchito. Zogulitsa zambiri zimafunikira kuti pakhale kusiyana pakati pa 20KPa. Ngati idayikidwa mdera losavomerezeka, idzafuna kuti pampu yamadzi yoyenda ikuwonjezeka ndi 2 mita yam'madzi. Mutu wogwira ntchito uyenera kukhazikitsidwa kumapeto kwenikweni komanso osakhazikika kumapeto kwenikweni. Musakhazikitse valavu yowongolera iyi pomwe wogwiritsa ntchito sakhala kutali ndi gwero lotentha kupitirira 80% ya malo ozizira.
