Screw cartridge valve flow control valve LFR10-2A-K

Kumanikidza muripo wevhavha

Zvinoenderana nechinzvimbo chevhavha yekumanikidza muripo weiyo yese hydraulic circuit, iyo inorema-sensitive pressure compensation control system inogonawo kukamurwa kuita pre-valve pressure compensation load-sensitive system uye post-valve pressure compensation load-sensitive system.Pre-valve compensation inoreva kuti vharuvhu yekumanikidza inorongedzerwa pakati pepombi yemafuta nevhavhavha yekudzora, uye muripo wepashure-vharuvhu zvinoreva kuti vharafu yekumanikidza inorongedzerwa pakati pevharuvhu yekudzora neiyo actuator.Mushure me-vharuvhu muripo wakanyanya kufambira mberi kupfuura muripo wepamberi-vhavha, kunyanya kana paine kusakwana kwepombi yemafuta.Kana mafuta epombi asina kukwana, vharafu huru inobhadharwa pamberi pevharuvhu ichaita kuti kuyerera kwakawanda kune mutoro wechiedza uye kuderera kuderera kune mutoro unorema, kureva kuti, chiedza chinotakura chinofamba nokukurumidza, uye actuator imwe neimwe haisi kuenderana. kana chiito chemukomboni chaitwa.Nekudaro, mushure me-valve muripo hauna dambudziko iri, ichagovera kuyerera kunopiwa nepombi muchikamu, uye kuwiriranisa zvese zvinokonzeresa zvinhu panguva yemubatanidzwa.Iyo mutoro inonzwa sisitimu yakakamurwa kuita pre-valve muripo uye post-valve muripo.Kana mitoro miviri kana kupfuura ichiita panguva imwe chete, kana kuyerera kunopiwa nepombi huru yakakwana kuti isangane nekuyerera kunodiwa nehurongwa, mabasa e-pre-valve compensation uye post-valve compensation yakafanana chaizvo.Kana kuyerera kunopiwa nepombi huru kusingakwanisi kusangana nekuyerera kunodiwa nehurongwa, muripo pamberi pevhavha ndeyotevera: kuyerera kwepombi huru kunotanga kupa kuyerera kumutoro nemutoro muduku, uye zvino inopa kuyerera. kune mamwe mitoro apo kuyerera kwezvinodiwa mutoro nemutoro muduku zvinosangana;Mamiriro ekubhadharwa kwemashure-vhavha ndeye: kuderedza kuyerera kwemutoro wega wega uchienzaniswa nenguva yakafanana yegore rapfuura (kuvhura kwevhavha) kuti uwane mhedzisiro yekuita kwakarongeka.Ndiko kuti, apo kuyerera kunopiwa nepombi huru hakugoni kusangana nekuyerera kunodiwa nehurongwa, kugoverwa kwekuyerera kunobhadharwa pamberi pevhavha yakabatana nemutoro, nepo kugovera kugoverwa kunobhadharwa mushure mokunge valve isingabatanidzi nemutoro, asi chete. zvinoenderana nehuwandu hwekuvhura kwevhavha huru.
