Rudzi rwevhavha yekuyamura

Zvinoenderana nechimiro chakasiyana, vharafu yekuyamura inogona kukamurwa kuita mapoka maviri: yakananga acting mhando uye inotungamira mhando. Direct acting relief valve ivharuvhu yekuyamura umo iyo hydraulic kudzvanywa kweiyo huru mutsara wemafuta inobata pane spool yakanyatso kuenzana nekudzvanywa inodzora chitubu simba. Zvinoenderana neakasiyana maumbirwo mafomu evhavha chiteshi uye yekuyeresa yekumanikidza, matatu akakosha maumbirwo anoumbwa. Hazvina mhosva kuti rudzii rwechimiro, iyo yakananga-inoita yekuyamura vharafu inoumbwa nezvikamu zvitatu: kudzvanywa inodzora chitubu uye kudzvanywa inodzora mubato, chiteshi chekufashukira uye dzvinyiriro yekuyera nzvimbo. Kuenzanisa pakati peyakananga inoshanda yekuyamura vharafu uye inotungamira vharafu yekuyamura: yakananga inoshanda yekuyamura vharafu: chimiro chiri nyore, kunzwisiswa kwakanyanya, asi kudzvanywa kunokanganisa zvakanyanya nekushanduka kwekuyerera kwekuyerera, kudzvinyirira mutemo kutsauka kwakakura, haina kukodzera kushanda pasi pekumanikidza kwakanyanya uye yakakura. kuyerera, kunowanzo shandiswa sevhavhavha yekudzivirira kana kune dzimwe nguva uko kudzvanywa kwemutemo kurongeka hakuna kukwirira.

Pilot relief valve: Chitubu chikuru chevharuvhu chinonyanya kushandiswa kukunda kukwenya kwepakati pevharuvhu, uye kuoma kwechirimo kudiki. Kana chiyero chekufashukira chichichinja chinokonzera shanduko huru yevharuvhu chitubu, shanduko yesimba rechirimo idiki, saka iyo valve inlet pressure shanduko idiki. High voltage regulation precision, inoshandiswa zvakanyanya mukudzvinyirirwa, hombe yekuyerera system. Iyo spool yevhavha yekuyamura inoiswa pasi pekuita kwekukwenya panguva yekufamba, uye kutungamira kwekukwenya mumaawa ekuvhura nekuvhara kwevhavha inongopesana, kuitira kuti maitiro evhavha yekuyamura akasiyana kana avhurwa. uye kana yakavharwa.
