Hydraulic balance valve Excavator hydraulic cylinder spool CXHA-XAN

Balance valve chimiro uye nheyo yekushanda

Iyo hydraulic balance valve inobvumira mafuta kuti afambe akasununguka kubva pachiteshi 2 kusvika kuchiteshi 1. Tinogona kuona kubva pamufananidzo wechimiro kumusoro kwechifananidzo chiri pasi apa kuti apo mafuta anodzvinyirira echiteshi chechipiri akakwirira kudarika chechiteshi 1, spool ye. iyo yakasvibira chikamu inofamba ichienda kuchiteshi 1 pasi pedhiraivha yekumanikidza kwemvura, uye cheki valve inovhurwa, uye mafuta anogona kuyerera akasununguka kubva pachiteshi 2 kuenda kuchiteshi 1.

Kuyerera kubva pachiteshi 1 kuenda kuchiteshi chechipiri kwakavharwa kusvikira kudzvanywa kwechiteshi chekutyaira kwasvika pane imwe kukosha uye spool yebhuruu inotamiswa kuruboshwe kuti ivhure vharafu revhavha kuitira kuti mafuta akwanise kuyerera kubva pachiteshi 1 kuenda kuchiteshi chechipiri.

Chiteshi chinovhara kana mutyairi wendege asina kukwana kuvhura spool yebhuruu. Kuyerera kubva pachiteshi 1 kuenda kuchiteshi 2 kwakagurwa.

Chiratidzo chemusimboti chevhavhavha yechiyero ndeyotevera;

Kuburikidza nekubatanidzwa kwevhavha yekutevedzana uye chiyero chevhavha mumufananidzo uri pasi apa, zvirongwa zvakawanda zvekugadzirisa zviyero zvemazinga makuru ekuyerera zvinogona kuwanikwa. Panguva imwecheteyo, kana mavharuvhu akasiyana-siyana akashandiswa muchikwata chekufambisa, zvakasiyana-siyana zvakasiyana-siyana zvekutonga zvinogona kuwanikwa. Rudzi urwu rwekutonga chirongwa runogona kuwedzera zvakanyanya zano rekugadzira.

Kuenzanisa vharafu sevhavha inodzikamisa vharafu yevhavha parallel yekubatanidza:

Maitiro ekudzora akasiyana anoitwa nemaparallel balancing mavharuvhu ane akasiyana pilot ratios. Iwo maviri akananga-anoita kuenzanisa mavharuvhu muMufananidzo 4 anosanganisira pre-control. Iyo yakaipa mutoro ivharuvhu yekufambisa iyo inodzora kusiyanisa kudzvanywa reshiyo ye2: 1 inogadziriswa. Kana mutoro uri wakanaka, ndiko kuti, kana dzvinyiriro painopinza yakakwira kupfuura kudzvanywa kwemutoro, yechipiri pre-controlled balance valve valve ichashandiswa, uye mutsauko wekumanikidza wekutonga unopfuura 10: 1. Kuti udzivise 10: 1 bhavhavhavha yevhavha kubva pakuvhura munzvimbo isina kunaka inotakura, pachava nevhavha yekudzivirira R (chaizvoizvo valve inoputika). Kana iyo inlet pressure yakakwira, iyo yekumanikidza inomisa vharuvhu R inovhura, uye 10: 1 bhavhavhavha yevhavha inogamuchira chiratidzo chemutyairi wekuvhura.

Yakasiyana yekudzora kuita inogona kuwanikwa nekugadzirisa kumanikidza kumisa vharafu R.
