Hydraulic balance valve Excavator hydraulic cylinder valve core RVCA-LAN

Ivhavha yekuyamura yakakamurwa kuva marudzi maviri: zvakananga kuita uye mutyairi anoshandiswa.

Nheyo yekushanda yevharuvhu yekuyamura yakananga:

Direct acting relief valve ivharuvhu yekuyamura umo iyo system yekumanikidza inoshanda pane spool yakanyatso kuenzana nekudzvanywa inodzora chitubu simba. Iyo chaiyo nzira yevhavha yekuyamura kuchengetedza kudzvanywa kwegadziriro iri pedyo nekusingaperi ndeyekuti: Kana iyo vheji yekuyamura ichishanda yakadzikama, iyo spool yakaenzana munzvimbo yekuvhura inowirirana nekuyerera kwekuyerera. Kana iyo system yekumanikidza yakakura kupfuura yekumisikidza kukosha kwevhavha yekuyamura, iyo hydraulic inosundidzira iyo spool kumusoro inowedzera, iyo spool inorasikirwa nechiyero chayo chepakutanga uye ichikwira kumusoro, iyo yekuvhura huwandu δ inowedzera, kushomeka kwemvura kunoderera, kuyerera kwemvura kunowedzera, uye iyo system pressure inenge yadonha inodzokera kune yekumisikidza kukosha. Kana iyo system yekumanikidza yakadzikira pane yakatarwa kukosha kwevhavha yekuyamura, iyo hydraulic inosundidzira spool kumusoro inova diki, spool inofamba ichidzika kubva panzvimbo yekutanga pasi pechiito chesimba rechirimo, iyo yekuvhura huwandu δ inodzikira, iyo mvura kuramba. kunowedzera, kuyerera kwekufashukira kunoderera, uye dhizaini yehurongwa inosimuka otomatiki, uye inenge ichidzokera kune yepakutanga set value. Naizvozvo, kana yakananga-inobata vharafu yekuyamura iri kushanda, iyo spool inofamba ichikwira uye ichidzika nekuchinja kweiyo system kudzvanywa, kuitira kuchengetedza iyo system kudzvanywa kunenge kuripo.

Nheyo yevharuvhu yekuyamura inoitwa mutyairi: Ivharuvhu yekuyamura ivharuvhu inoshandisa vheruvhu yekufambisa kudzikamisa kumanikidza uye kudzora mafashama evharuvhu huru.

Nevhavha yekuyamura mu hydraulic system, iyo dhizaini yekumanikidza haigone kudarika kudzvanywa kwakaiswa nevhavha yekuyamura, saka vheji yekuyamura inoitawo basa rekudzivirira kuwanda kwehurongwa. Kana iyo valve yekuyamura inoshandiswa sevhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhavhava,kupindwa muganho kana sisitimu yaremerwa inofanira kushandiswa segadziriro yekumanikidza yevhavha. Kuwedzeredza kana chiteshi chevharuvhu chavhurwa, mafuta anodonha achidzokera kutangi, achiita basa rekuchengetedza kuchengetedza. Ivhavhavha yekudzivirira inowanzovharwa kana sisitimu iri kushanda zvakajairika.
