Matanidza iwo epakati paramita ema bulldozers
Tonnage uye kugadzirisa simba
Iyo tonnage yebulldozer inosarudza zvakananga chiyero chekumanikidza uye kuyerera kudiwa kwevhavha inotungamira. Semuyenzaniso:
Madiki nepakati-mabhurudhoza madiki (Zvisingasviki kana kuenzana nematani makumi maviri): Kazhinji sarudza vharuvhu yekutungamirira ine kumanikidzwa kwehuwandu hwe10-20MPa uye kuyerera kwe40-100L/min, yakadai seZT series hydraulic directional valve (flow rate ye40-100L / min, pressure yakaenzana neLes2MP).
Large bulldozers (>20 tons): inoda kufananidzwa nepamusoro-soro, sevhavhavhavhavha yekufambisa inoshandiswa mubhurudoza re520 horsepower, ine kuyerera kwe246L/min uye kumanikidzwa kwe2.69MPa, yakabatanidzwa nega yega-vharuvhu yekukiya kuti igone kurarama nemitoro inorema uye nzvimbo yakaoma.
Simba rekuenzanisa: Tarisa kune injini yeflywheel simba (yakadai se447kW yeCaterpillar D10T2) kuti uone kuti vheji yekutungamirira inogona kumira nepamusoro-soro ye hydraulic system yose.
Model chimiro kuenderana
Pane misiyano yakakura mukugadzirwa kweanotungamira masisitimu pakati pemhando dzakasiyana. Semuyenzaniso:
Crawler bulldozer: Izvo zvinodikanwa kuti usarudze vheji yekufambisa inotsigira track yekumhanyisa musiyano wekutonga, senge 16Y-76-22000 yekufambisa vharafu yakarongedzerwa SD16 bulldozers, iyo inogona kubatanidzwa nebrake clutch kuti iwane chaiyo inotungamira.
Wheeled bulldozer: Funga kubatanidza vharuvhu yekuyerera (yakadai seVSFA rudzi) ine giya rekutungamirira kuti riwedzere kufambiswa kuburikidza nemusimboti wekuenzana kwekusimudzira.

Chinja kunharaunda yebasa uye mamiriro ekushanda
Terrain uye mutoro mamiriro
Complex terrains (migodhi, makomo): Kunyanya kunofanira kupiwa kune mavharuvhu ekutungamirira ane kumanikidzirwa muripo wekushanda, zvakadai semavhavhavha ekubatanidza ane mavharuvhu ekuchengetedza akabatanidzwa, ayo anogona kungoerekana agadzirisa kudzvinyirira kana nzira yakanamatira (kumanikidza chikumbaridzo kunowanzoita 10-30MPa) kudzivirira kukanganisa kune zvikamu zve hydraulic.
Heavy load bulldozer: Zvinodikanwa kusarudza mavharuvhu emuviri ane simba rekudzivirira (sepamusoro-simba rakakandwa simbi kana simbi), uye simbisa kusakara kwepakati pevharuvhu. Semuenzaniso, mavharuvhu akaputirwa ne tungsten carbide anogona kutsungirira kusakara kweanogara achiremerwa mashandiro.
Kunyanya kuchengetedza kwezvakatipoteredza
Yepamusoro/yakaderera tembiricha nharaunda: Sarudza zvinhu zvinodzivirira tembiricha (zvakadai sesilicon carbide ceramic valve blocks inokwanisa kumira tembiricha inosvika 1600 degree) kana mavharuvhu anotungamira ane tembiricha yekudzora muripo kudzivirira jamming yevharuvhu inokonzerwa nekuwedzera kwekupisa uye kudhonzwa.
Guruva guru/nzvimbo inoora: Kutora duplex stainless simbi (yakadai se2205) kana Hastelloy valve body, ine O-inovharika mhete (sefluororubber VITON) kudzivirira kupindira kweguruva nekuora kwepakati.

Hydraulic system parameter inoenderana
Kuyerera uye kudzvanywa kunoenderana
Kuyerera kwekuverenga: Kubva pakumhanya kwekushanda kwesilinda (yakadai sepiston tsvimbo yekufamba kumhanya kwe50mm/s) uye cylinder dhayamita (senge φ 125mm), verenga iyo inodiwa yekuyerera (Q=π× r ² × v) kuve nechokwadi kuti iyo yakanyanya kuyerera yevhavhavhavhavha (yakadai seyakadai 125mm).
Chiyero chekumanikidza: Iyo yakatemerwa kudzvanywa kwevhavha inotungamira inofanira kunge yakakwira kupfuura iyo yepamusoro yekumanikidza system (kazhinji 1.2-1.5 nguva yekushanda kumanikidza). Semuenzaniso, kana kushanda kwekushanda kuri 15MPa, valve ine rated pressure ye20MPa inofanira kusarudzwa.
Kugarisana kwemafuta
Simbisa iyo hydraulic oiri mhando (yakadai semafuta emaminerari, synthetic mafuta) uye viscosity range (yakadai se ISO VG 46) yakakodzera vheji yekutungamirira kudzivirira chisimbiso kuchembera kana kuvhara kwevhavha yepakati kunokonzerwa nekusawirirana kwemafuta.

Kuita uye kushanda zvinodiwa
Kudzora kurongeka uye kumhanya kwekupindura
Sensitivity yevharuvhu musimboti: Sarudza vharuvhu yekutungamirira ine proportional control kana yemagetsi control function (yakadai seBPBS hydraulic steering gear + VSFA inoyerera amplification valve) kuti uwane "diki angle yakanaka kugadzirisa" uye nekukurumidza kupindura, kuvandudza kushanda zvakanaka.
Kudzorera kuvimbika: Zvakakosha kutarisa kuoma kwechitubu chekudzoka uye hutano hwezvikamu zvekuisa chisimbiso kuti uone kuti nheyo yevhavha yakakurumidza kudzoka pakati mushure mekusunungura tsvimbo yekufambisa, kudzivisa kutsauka.
Chengetedzo uye redundancy dhizaini
Kuzvikiyira uye kudzivirira misoperation: Semuyenzaniso, vheruvhu yedhiraivha ye520 horsepower bulldozer inosanganisa yega-vharuvhu yekukiya. Kana uchitanga, mubato unoda kudzorerwa panzvimbo yawo yepakutanga kudzivirira tsaona dzinokonzerwa nekusashanda zvakanaka.
Redundant system: Mumamiriro akavimbika epamusoro akadai semigodhi, mavharuvhu ekudzoreredza ane backup solenoid mavharuvhu anogona kusarudzwa. Kana iyo vharafu huru ikatadza, inochinja otomatiki kudunhu rekuchengetedza, ichideredza nguva yekudzikira.
