Zvatiri kutaura pamusoro peiyo huru yekuyamura vharafu ndeye apo system yekumanikidza inokwira zvishoma, modhi yechitanhatu
Kana mutsauko wekumanikidza pakati pemigumo miviri yevharuvha huru inodarika basa rechitubu chakapfava chevhavha huru, iyo huru plunger valve inosimudzwa, vharafu huru inovhurwa, chitubu chakabatana netangi remafuta, yakawanda. yeoiri inodzorwa nepachiteshi chikuru chevharuvhu, yobva yayerera ichidzokera kutangi reoiri kuburikidza nechiteshi cheoiri chekudzoka, inova nzira yekudzora mafashama. Kunzwisisa musimboti uyu unogona kunzwisisa chirevo chekushanda chebhoom kuchengetedza vharafu pasi nekuenzanisa.
Kana iyo hydraulic excavator ruoko yadzikiswa, zvakakosha kuziva kuti inovimba nePPC vharafu inodzorwa kubva pakuchinja.
Mafuta ekumanikidza anotungamira anotanga kusundira slide valve inodzora vharafu huru (vharuvhu yakaenzana nevharuvhu yekutyaira muvharupu yekuyamura mutyairi, inofamba panguva ino.
Mafuta ari mukamuri yepasi peruoko anodzokera kutangi kuburikidza neburi remukati remafuta revharuvhu huru kuburikidza nenzira yakavhurwa nevharuvhu. Kana mafuta ekumanikidza achiyerera achipfuura nepagomba rekunyorovesa revhavha huru yevhavha yekubata, kudonhedza kwemhepo kunogadzirwa, kuitira kuti kudzvanywa kwemafuta kunobata kumusoro uye kuzasi kumagumo kwevhavha huru kusaenzana, kuumba kumwe kudzvanywa mutsauko. Ivhavha huru inovhurwa, uye mafuta ekumanikidza anoyerera kubva pasi pebhoom anoyerera nepakati pevhavha huru kuenda kubhoom control valve. Kana paine kusajairika kwepamusoro kudzvinyirirwa muchikamu chepasi chebhoom cylinder, vharafu yekudzivirira muvhavha yekubata inovhurwa kuti iite basa rekudzivirira.
