Mamiriro ekushandisa uye zvakanakira zvehunyanzvi zve bulldozer pilot mavharuvhu
Kugonesa kudzora basa remumba: Vhuru yekutyaira inongodzora clutch kuburikidza neelectro{{0}hydraulic control, yakasanganiswa nekuvhara basa rehydraulic torque converter, zvichiita kuti bulldoza ichinje kubva kune hydraulic mechanical transmission nekumhanya kwakaderera kuenda kune mechanic transmission nekumhanya kwakanyanya, kuderedza kushandiswa kwemafuta neinodarika gumi%. Semuyenzaniso, iyo SD52-5 bulldozer kubva kuShantui ine theoretical yakanyanya kutakura ivhu kugadzirwa kwe1313m ³/h iri chinhambwe che 40m, uye kushanda kwayo kwakanaka kunoenderana nekunyatso kudzora kweiyo hydraulic system nevhavhavha yekutyaira.

Kuvandudzwa kwekuchengetedza uye kunyaradza: Mamwe mabulldozer (akadai SD52-5) ane zvigaro zveKAB zvinogona kutenderera 15℃, pamwe chete nevhavhavha yekufambisa kutarisa mamiriro evhu rekusunungura, kuvandudza kuonekwa kwekushanda uye kuchengeteka. Uye zvakare, iyo modular yekubatanidza yevhavhavhavha ine yepakati kufambisa uye inotungamira clutch inogona kuwana yekupaka mabhureki basa uye kudzivirira chikomo kutenderera.
Shandura kune akawanda mamiriro ekushanda: Kudzora kudzvanywa huwandu hwevhavhavha yekutyaira inoda kugadziridzwa zvinoenderana nezvinodiwa zvekushanda. Semuyenzaniso, DJS pilot valve ine control pressure range ye 0.5-2.5MPa ye rotary bucket linkage uye 0.5-2.0MPa ye boom linkage, iyo inogona kuchinjirwa kuma hydraulic masisitimu emahombe uye epakati nepakati maloaders nemabulldozer akadai seZL040 neZL. Pilot valve idiki hydraulic control valve inoshandiswa kudzora kuita kweiyo main hydraulic valve, ye "command element" muma hydraulic system. Inoshandura mafuta akaderera-kudzvinyirira kuita zviratidzo zve hydraulic kuburikidza nekugamuchira zvikwangwani zvekushanda kwemagetsi kubva kune vashandi (zvakadai sechiito chekudzora levers uye pedals), inotyaira kufamba kwepakati pevhavha huru, uye nokudaro inodzora zviito zvezvishandiso zvebulldozer zvinoshanda (zvakadai sefoshoro uye zvinosunungura ivhu) uye maitiro ekufamba.

Pfupiso yemabhenefiti ekushandisa, kunyaradza kwemutyairi: kunoderedza zvakanyanya kuneta kwekushanda, kunyanya panguva yebasa rinoenderera mberi.
Kurongeka kwebasa remumba: Wana millimeter level blade chinzvimbo chekutonga uye yakatsetseka kukurumidza kugadzirisa, kuvandudza mhando yebasa remumba senge flatness uye slope control.
Kubudirira kwebasa rechikoro, kukurumidza kupindura, uye kutonga kwakanyatsoita kwakaderedza kudzokorora mashandiro uye kwakavandudza basa rinoshanda pane imwe nguva yeyuniti.
Kudzivirirwa kwemuchina uye kudzora kwakatsetseka kunoderedza hydraulic shock, kuwedzera hupenyu hwe hydraulic zvikamu uye zvimiro zvikamu.
*Kuwedzera basa: Inopa puratifomu yakakosha yekubatanidza zvidzori zvemagetsi zvepamberi senge otomatiki masisitimu ekuyera uye kuremote control, kunyanya ye electro-hydraulic proportional pilot mavharuvhu.

Kukosha
Zvinogona kutaurwa kuti pasina pilot control system, kushanda, kugadzikana, uye kushanda kwemabulldoza emazuva ano (kunyanya epakati kusvika kuhombe neakakwirira-modhiyo ekupedzisira) achadzikiswa zvakanyanya. Iyo pilot valve ndiyo yakakosha yekuisa chikamu chepilot control system, inoshanda sebhiriji pakati pechinangwa chemutyairi uye ine simba hydraulic actuator yemuchina. Kuita kwayo uye kuvimbika kunotaridza zvakananga chiitiko chekubata uye kugona kushanda kweiyo bulldozer yese.
