Excavator zvikamu 328-4314 C7 Solenoid valve yeCarter 962H 962K 966H 972H

Mhando uye mafomu e electro-hydraulic proportional mavharuvhu emichina yekuvaka
Electro-hydraulic proportional valves anosanganisira mavharuvhu anoyerera, proportional pressure valves uye proportional directional valves. Zvinoenderana nehunhu hwe hydraulic kushanda kwemichina yekuvaka, kune marudzi maviri e electro-hydraulic proportional mavharuvhu: imwe ndeye spiral cartridge proportional mavharuvhu, uye imwe inotsvedza mavharuvhu akaenzana.

Iyo spiral cartridge valve inhengo yakamisa iyo electromagnetic proportional cartridge pane oiri circuit assembly block kuburikidza neshinda. Iyo spiral cartridge valve ine maitiro ekugadzirisa kushandiswa, pombi yekuchengetedza uye kudhura kwakaderera, nezvimwewo. Yakashandiswa zvakanyanya uye zvakanyanya mumichina yekuvaka mumakore achangopfuura.
Inowanzo shandiswa spiral cartridge type proportional valve ine maviri, matatu, mana uye akawanda-pass mafomu, maviri-nzira proportional vharafu inonyanya kuenzana throttle vharafu, inowanzobatanidzwa pamwe nezvimwe zvinoriumba kuti iite inoumbwa vharafu, kuyerera, kudzvinyirira kudzora; Iyo-nzira-nhatu yakaenzana vharafu inonyanya kuenzana kudzikamisa vharafu, uye zvakare iri proportional vharafu rinoshandiswa zvakanyanya mune mobile mechanical hydraulic system, iyo inonyanya kushandisa dhirivha yemafuta eiyo hydraulic multi-way valve.

Iyo nzira nhatu-yakaenzana kudzvinyirirwa kuderedza vharuvhu inogona kutsiva iyo yechinyakare dhizaini yekudzikisa pilot valve, iyo ine kuchinjika kwakawanda uye yakakwirira kudzora kurongeka kupfuura iyo manual pilot valve. Inogona kuitwa kuti iite proportional servo control manual multi-way valve sezvinoratidzwa mumufananidzo 1. Maererano nezviratidzo zvakasiyana-siyana zvekupinza, mhepo inoderedza vhavha inoita kuti piston inobuda ive yakasiyana-siyana kana kuti kuyerera kwekuyerera kuti iwane kuenzanirana kwekutonga kwekudzingwa kwevakawanda. - nzira vharafu spool. Four-nzira kana multi-nzira screw cartridge proportional mavharuvhu anobvumira kudzora kwega kwega rekushandisa.
