Hydraulic balance valve Excavator hydraulic cylinder valve core RPEE-LBN

Zolakwa zambiri za valve yothandizira ndi: kugwedezeka ndi phokoso; Kupanikizika kosinthika kumakhala kochepa, kusinthako sikungatheke; Kupanikizika kosintha kumakhala kwakukulu, kusinthako sikungatheke; Kusintha kwamphamvu; Kutayikira, ndi zina. Zomwe zimayambitsa zolephera izi ndi njira zothetsera mavuto ndi izi:

1. Kugwedezeka ndi phokoso

1) Phokoso lamadzi liyenera kutengedwa malinga ndi zifukwa zotsatirazi:

(1) Phokoso la cavitation cavitation ndi eddy panopa ndi shear fluid fluid pambuyo pa valve kusefukira iyenera kusinthidwa;

(2) Phokoso la mphamvu yamagetsi pa nthawi yotsitsa valavu yothandizira kuyenera kuonjezera nthawi yotsitsa, ndipo phokoso lapamwamba kwambiri lomwe limayambitsidwa ndi kugawanika kwapakati pa valve yoyendetsa ndege ndi valavu yaikulu ya slide iyenera kupititsa patsogolo kulondola kwa geometric. ya valavu, onjezani m'mimba mwake wa chitoliro chamafuta obwerera, sankhani kasupe wofewa kwambiri wa valve ndi kukhuthala koyenera kwa chitoliro chobwerera mafuta ndi mpweya, muyenera kuyang'ana chisindikizo ndi kutulutsa. Ngati kupsyinjika kumbuyo kwa chitoliro cha mafuta obwerera ndi kwakukulu kwambiri, m'mimba mwake wa chitoliro cha mafuta obwerera ayenera kuwonjezeka ndipo chitoliro cha mafuta obwerera chiyenera kukhazikitsidwa mosiyana.

(3) Chipinda chothandizira chapakati chowongolera mpweya mumlengalenga, chiyenera kuyang'ana chisindikizo ndi kutuluka kwa mpweya kupitirira mtengo wovomerezeka, ziyenera kusankhidwa kuti zigwirizane ndi kutuluka kwa valve yothandizira.

2) Phokoso lamakina, njira zofananira ziyenera kuchitidwa molingana ndi zifukwa zotsatirazi:

Vavu yolowera ndi bowo la valavu ndizolimba kwambiri kapena zomasuka kwambiri kuti zipangitse kugwedezeka ndi phokoso, ziyenera kuyang'ana ndikukonzanso kasupe wowongolera ndi wofewa kwambiri kapena wopunduka kuti apangitse phokoso, ayenera m'malo mwa kasupe wowongolera kuthamanga.

Ngati nati yoyendetsera kuthamanga ili yotayirira, iyenera kumangirizidwa ndipo valavu ya taper iyenera kutha, iyenera kukonzedwa munthawi yake kuti ipange phokoso la resonance ndi zigawo zina za dongosolo, ndipo iyenera kuchitidwa munthawi yake kuti ichotse resonance.
