E330C huru yekuyamura vharafu 103-8177 Excavator accessories proportional solenoid valve

Mhando uye mafomu e electro-hydraulic proportional mavharuvhu emichina yekuvaka
Electro-hydraulic proportional valves anosanganisira mavharuvhu anoyerera, proportional pressure valves uye proportional directional valves. Iwo hydraulic oparesheni maitiro emichina yekuvaka akakamurwa kuita marudzi maviri e electro-hydraulic proportional mavharuvhu muchimiro chechimiro: imwe ndeye spiral cartridge proportional mavharuvhu, uye imwe inotsvedza vharafu proportional mavharuvhu.
Iyo screw cartridge proportional valve is threaded electromagnetic proportional cartridge component yakagadziriswa paoiri circuit assembly block. Iyo screw cartridge valve ine hunhu hwekuchinjika application, pombi kuchengetedza uye yakaderera mutengo, uye yakashandiswa zvakanyanya uye zvakanyanya mumichina yekuvaka mumakore achangopfuura.
Zvakawanda. Inowanzo shandiswa spiral cartridge type proportional valve ine maviri, matatu, mana uye akawanda-pass mafomu, maviri-nzira proportional vharafu main proportional throttle vharafu, kazhinji zvikamu zvayo pamwe chete kuumba composite vharafu, kuyerera, kudzvinyirira kudzora; Three way ratio
Iyo huru yakaenzana kudzvinyirira kudzikisa vharafu zvakare ndiyo inonyanya kushandiswa yakaenzana vharafu mune mobile mechanical hydraulic system, iyo inonyanya kushandisa hydraulic multiway valve pilot mafuta circuit. Iko kushandiswa kwematatu-nzira yakaenzana kudzvinyirira kudzikisa vharafu kunogona kutsiva yechinyakare bhuku decompression kutanga
Pilot vharuvhu, iyo ine zvakawanda kuchinjika uye yakakwirira kutonga kurongeka kupfuura manual pilot valve. Inogona kugadzirwa kuva proportional servo control manual multi-way valve sezvakaratidzwa muFigure 1. Zviratidzo zvakasiyana-siyana zvekupinza, mhepo inoderedza mhepo inoita kuti piston inobuda ive yakasiyana-siyana kana kuyerera.
Ipapo inoziva kuenzanirana kwekutonga kwekutamiswa kweakawanda-nzira vharafu spool. Four-nzira kana multi-nzira screw cartridge proportional mavharuvhu anogona mumwe nomumwe kudzorwa nokuda kushanda mudziyo.
