Excavator John Deere 200-6210 distributor hydraulic proportional solenoid valve

     Iyo huru yekuyamura vharafu hydraulic pombi inogara ichiburitsa oiri, asi kana iyo hydraulic pressure yakanyanya, inokonzeresa kukuvadzwa. Naizvozvo, iyo hydraulic circuit yakashongedzerwa nevhavha yekufashukira kudzivirira kukuvadzwa kwepombi. Iyo hydraulic cylinder yakawedzera kureba, kana kupfupika, kana iyo hydraulic cylinder uye hydraulic mota inowedzera simba rakawanda, kuitira kuti iyo hydraulic cylinder uye hydraulic mota inomira, mafuta anotumirwa ne hydraulic pombi haazoendi, saka kuti iyo hydraulic device ine simba rekuputika, iyo hydraulic pressure inokwira zvakanyanya, uye pombi yakakura zvikuru mutoro. Izvi zvichaunza kukanganisa kwepombi, kuitira kuti hydraulic pressure iwedzere kusvika kune imwe nhanho, mafuta kubva papombi achadzokera kune tangi yemafuta ekushanda, zvakakosha kuisa nzira yekuyerera, kuitira kuti hydraulic pressure irege. kukwira zvakanyanya. Panguva imwecheteyo, kumanikidzwa kwevhavha yekuyamura kunogonawo kugadziriswa kuti uone kuti kg / cm2 inobvumirwa kukwira sei. Ivhavha yekuyamura ibasa rinotsanangurwa pamusoro apa uye rinoiswa munharaunda pakati pe hydraulic pump uye valve control valve, asi inowanzoiswa pamwe chete nevhavha yekudzora. Kana mamiriro evhavha yekuyamura asina kunaka, kuderera kwakadzika kuchazarura, ipapo hydraulic pressure haizopfuuri, uye simba re hydraulic cylinder uye hydraulic motor inenge isina simba. Uye zvakare, kana vharafu yekuyamura isina hukama, kana kudzvanywa kwakakwira, kunokonzera kubuda kwemafuta, uye pakupedzisira mafuta kubva papombi uye kubuda kwemafuta kwakafanana, iyo hydraulic pressure haigone kukwira kumusoro, kuitira kuti kusimba kwehydraulic cylinder uye iyo hydraulic mota haina kusimba
