Injiniya yemigodhi yemichina zvikamu Hydraulic valve cartridge balancing valve CBIG-LJN

Mavharuvhu ekuyamura ekutyaira anowanikwa mune zvakasiyana-siyana zvigadziriso. Iyo yakajairwa-chikamu chetatu-yakadzika dhizaini yekuyamura vharafu, iyo inoumbwa nezvikamu zviviri: pilot vharafu uye huru vharuvhu.

Iyo taper pilot vharafu, gomba rekunyorovesa (yakagadziriswa throttle hole) pahombe yevharuvhu uye kudzvanywa kunodzora chitubu pamwe chete zvinoumba mutyairi hafu-bhiriji chikamu chekumanikidza negative mhinduro yekutonga, iyo ine basa rekupa iyo huru nhanho yekumanikidza kumanikidza mushure mevharuvhu yekutyaira. kudzora kudzvinyirira kukamuri yepamusoro yevharuvhu huru spool. Iyo huru spool ndiyo muenzanisi weiyo huru control loop. Chiso chepamusoro chinoshanda sesimba rekuraira reiyo main spool, nepo kumucheto kwepasi kunoshanda sekumanikidza kuyera pamusoro peiyo huru loop uye kuita sesimba remhinduro. Simba rinoguma rinogona kutyaira spool, kugadzirisa saizi yechiteshi chekufashukira, uye pakupedzisira kuzadzisa chinangwa chekutonga nekugadzirisa kudzvanywa kweiyo inlet pressure P1.

Paunenge uchishanda, iyo dzvinyiriro yemvura inoshanda pane yekuyeresa yekuyera pamusoro peiyo huru spool uye mutyairi spool panguva imwe chete. Kana iyo pilot valve 1 isina kuvhurwa, mafuta haayerere mukamuri yevhavha, uye kumanikidza kunoshanda pane huru spool mumativi ese ari maviri akaenzana, asi nekuti iyo inoshanda yekumanikidza nzvimbo yekumusoro kwekumusoro yakakura kupfuura iyo inoshanda yekumanikidza nzvimbo. yemucheto wezasi, iyo huru spool iri munzvimbo yepasi pasi pechiito chesimba rinoguma, uye chiteshi chevhavha chakavharwa. Kana simba rekupinda mukati richiwedzera zvekuvhura vharuvhu yekutyaira, mvura inoyerera nepaburi rekunyorovesa riri pahombe yevharuvhu huru uye vharuvhu yekutyaira ichidzokera kutangi. Nekuda kwekunyorovesa kwegomba rekunyorovesa, iyo huru spool inoiswa kune ekumusoro uye yakaderera nzira yekumanikidza yemvura haina kuenzana, iyo huru spool inokwira kumusoro pasi pechiito chekumanikidza musiyano, inovhura chiteshi chevhavha, inoona mafashama. , uye inochengetedza kugadzikana kwekutanga kwekumanikidzwa. Kufashukira kudzvinyirira kunogona kugadziridzwa nekugadzirisa kudzvanywa kunodzora chitubu chevhavha yekutyaira.
