Excavator PC200-8 excavator yakajairika njanji yekumanikidza vharafu 6754-72-1220

1. The excavator regenerative valve inogona kukurumidza kukurumidza kuwa uye kuvandudza kushanda kwekushanda.

2, yekuchera bhakiti tsvimbo yekuvandudza vharafu inosanganisira sleeve yevharuvhu, screw plug yakarukwa neimwe mugumo wevhavhavhavha, musoro wevharuvhu wakabatana neimwe magumo evhavha sleeve, pane chigaro chakagadziriswa muvharuvha sleeve uye plug. , imwe mugumo wechikamu che elastic chakabatana nechigaro chakagadziriswa, imwe mugumo wevhavha spool sliding yakabatana nevhavha sleeve yakabatanidzwa kune imwe mugumo wechikamu che elastic, imwe mugumo wevhavha spool yakabatanidzwa nemusoro wevhavha. , Isai plunger ine sliding connection pakati pemagumo emusoro wevharuvhu uchienda mukati mevhavha sleeve, chikamu chemusoro wevharuvhu uri kunze kwevhavhavhavha inopihwa yekutanga radial kuburikidza negomba, imwe mugumo weplunger inoenda. kuburikidza nemagumo emusoro wevharuvhu uye inobatanidza nechepakati pevhavha, imwe mugumo weplunger inoenda kune yekutanga radial kuburikidza negomba, uye annular groove inopiwa pane denderedzwa revhavha yepakati. Iyo sleeve yevharuvhu inopihwa yechipiri radial kuburikidza negomba uye yechitatu radial kuburikidza negomba rinoenderana neannular groove.

Ivhavha huru yekuyamura yakaiswa pamucheto wepamusoro nepamusoro wevhavha huru yekudzora, imwe yepamusoro uye imwe yakaderera. Ivhavha inoisa iyo yakanyanya kudzvanywa kuti iyo yese hydraulic system ishande. Kana iyo system yekumanikidza inodarika kudzvanywa kweiyo huru yekuyamura vharafu, iyo huru yekuyamura vharafu inovhura dunhu remafuta retangi rekudzoka kuti riwedzere mafuta e hydraulic kudzokera kutangi kuchengetedza iyo yese hydraulic system uye kudzivirira yakawandisa mafuta kumanikidza.
