Excavator hydraulic pump solenoid valve proportional solenoid valve TM82002

Iko kufambira mberi kwetekinoroji ye electro-hydraulic proportional valves uye zvimwe zvakakosha zvemichina yeinjiniya inoita kuti kudzora kwemagetsi kweakasiyana masisitimu akadai segiya, dhiraivha, mabhureki uye ekushanda zvishandiso zveinjiniya mota zviitike. Kune iyo mashini iyo inowanzoda kutamiswa kubuda, iyo proportional servo control manual multiway valve driver yakafanana neFigure 1 inogona kushandiswa kupedzisa. Kushanda kwemagetsi kune zvakanakira kupindura nekukurumidza, kuchinjika wiring, kusanganisa kutonga uye nyore kutarisana nekombuta, saka yemazuva ano michina yekuvaka hydraulic mavharuvhu ave zvakanyanya uye zvakanyanya kushandiswa kwemagetsi anodzorwa mutyairi anodzorwa electro-hydraulic proportional mavharuvhu (kana electro-hydraulic switch. mavharuvhu) pachinzvimbo chebhuku rakananga kushanda kana hydraulic pilot inodzorwa mavharuvhu akawanda. Imwe mukana wakakosha wekushandisa electro-hydraulic proportional mavharuvhu (kana electro-hydraulic on-off mavharuvhu) ndeyekuti huwandu hwemabatiro ekushanda hunogona kudzikiswa zvakanyanya pamotokari dzeinjiniya, izvo zvisingaite chete kurongeka kwekabhu kuve nyore, asiwo zvinobudirira kuderedza kuoma. yekushanda, iyo ine zvakakosha zvinoshanda zvakakosha pakuvandudza kunaka uye kubudirira kwebasa. Mufananidzo 2 ndiyo TECNORD JMF control lever (joystick), kushandisa joystick kunogona kunyatso kudzora multi-piece electro-hydraulic proportional valve uye on-off valve muFigure 2. The rocker anogona kuona proportional control kana kushandura control mune zvose X uye Y axis nzira, uye iko kushandisa kuri nyore kwazvo.
