Excavator huru yekudzora vharafu PC200-8 PC220-8 yekuchengetedza vharafu 723-90-76101

Kuburutsa vharafu inoshanda musimboti: kuburitsa vharafu yekuyamura inoumbwa nevhavha yekuyamura uye cheki vharafu. Kana iyo system yekumanikidza inosvika pakuvhurika kwevhavha yekuyamura, valve yekuyamura inovhurwa uye pombi inoburitswa. Kana iyo system yekumanikidza inodonha kusvika pakuvhara kwekuvhara kwevhavha yekuyamura, vheji yekuyamura inovhara uye pombi inotakura muhurongwa.
Ivhavha yekudzikisa ivhavha inogona kuita kuti hydraulic pombi ibudise pasi pemamwe mamiriro. Ivhavha yekudzikisa inowanzova chivharo chekuyamura ine maviri-nzira valve (kazhinji solenoid valve), iyo inoshandiswa kugadzirisa dambudziko guru regadziriro (pombi yemafuta) kana isina kubudiswa. Kana mafuta ekumanikidza aburitswa (nembiri-nzira mbiri valve chiito chekushandura), mafuta ekumanikidza anodzoserwa zvakananga kutangi, uye kudzvanywa kwepombi yemafuta kunoderedzwa kusvika kunenge zero, kuitira kuti uwane imwe loop control uye kugadzirisa hupenyu hwepombi yemafuta uye kuderedza kushandiswa kwesimba.
Kuve kune yakabatanidzwa loop muchiuno. Ivhavha yekuderedza kudzvinyirira inoshandiswa kugadzirisa kumanikidzwa kunodiwa nemuiti, iyo iri munhevedzano muchiuno uye kazhinji haigoni kushandiswa zvakasiyana.

Ruzivo rwakawedzerwa:
Mhando yevharuvhu yekuburitsa:
Penetration type
Iyo yekuburitsa chiteshi uye vharafu yekumanikidza inomiswa zvakasiyana. Pakuburutsa, spool yega yega iri munzvimbo isina kwayakarerekera, uye mafuta kubva kutsime reoiri anoburitswa achidzokera mutangi kuburikidza neakakosha chiteshi chemafuta kuburikidza nevharuvhu yega yega, uye chiteshi chemafuta ekuburutsa chinomhanya nepakati pega rega rekudzokera shure. Kana imwe yevhavha iri kushanda (kureva kuti, nzira yemafuta yekudzikisa yakagurwa), mafuta anobva kutsime reoiri anopinda mune inodzorwa actuator kubva kuvharuvhu inodzosera yemugwagwa, uye kudzvanywa kwekushanda kunogumira nevhavha yekumanikidza mukati. mufananidzo.
Kuburutsa mhando
Ivhavha yekudzikisa uye yevhavha yekudzivirira inosanganiswa kuti iite pilot-operated pressure valve, iyo yose iri vheji yekudzikisa uye yevhavhavhavhavhavhavha, uye dzimwe nguva valve inoputika. Panguva yekudzikisa, nzira yemafuta yekudzora inopfuura nepakati yega yega inotungamira vharafu, iyo yakafanana neyekuburutsa mafuta.
