Excavator yekuvaka michina yemidziyo 439559 9101532 solenoid vharafu

Hydraulic proportional valve ndiyo yakaenzana electromagnet yekupinda voltage siginecha muvharuvhu kuti ibudise chiito chinoenderana, kuitira kuti iyo inoshanda vharafu spool displacement, vharavhavha yesaizi shanduko uye kupedzisa kudzvanywa uye kuyerera kwezvinobuda zvikamu zvinoenderana nemagetsi ekuisa. Spool displacement inogona zvakare kudyiswa kumashure mechina, hydraulically kana magetsi. Electro-hydraulic proportional valve ine akasiyana mafomu, nyore kushandisa magetsi uye komputa kutonga kweakasiyana electro-hydraulic masisitimu, yakakwirira kutonga kurongeka, kuchinjika kuisirwa uye kushandisa, uye yakasimba anti-kusvibiswa kugona, uye zvimwe zvakanakira, nzvimbo yekushandisa iri kuwedzera. . Mumakore achangopfuura, kuvandudzwa uye kugadzirwa kweplug-in proportional mavharuvhu uye proportional multiway mavharuvhu anonyatso funga nezve hunhu hwemichina yekuvaka, ine pilot control, kurodha sensing uye kumanikidza muripo mabasa. Izvo zvakakosha zvikuru kuvandudza iyo yakazara tekinoroji level ye mobile hydraulic muchina. Kunyanya, electronic control pilot operation, wireless remote control uye wired remote control operation yakaratidza tarisiro yakanaka yekushandisa.

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 mutengo wakaderera, uye yakashandiswa zvakanyanya uye zvakanyanya mukugadzira michina mumakore achangopfuura. Inowanzo shandiswa spiral cartridge proportional valve ine maviri, matatu, mana uye akawanda-pass mafomu, maviri-nzira proportional vharafu main proportional throttle vharafu, iyo kazhinji inoumba pamwe chete kuita vheruvhu inoumbwa, pa
Kuyerera uye kudzvinyirira kutonga; Iyo nzira nhatu-yakaenzana vharafu ndiyo hombe yakaenzana kudzvinyirira kudzikisa vharafu, inova zvakare inonyanya kushandiswa proportional vharafu mune mobile mechanical hydraulic system. Iyo inonyanya kushanda iyo hydraulic multiway valve pilot mafuta wedunhu. 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 kugadzirwa kuva proportional servo control manual multi-way valve sezvakaratidzwa muFigure 1. Nezviratidzo zvakasiyana-siyana zvekupinza, mhepo inoderedza mhepo inoita kuti piston inobuda ive yakasiyana-siyana kana kuti inoyerera kuti iwane kuenzanirana kwekutonga kwekudzingwa kwevakawanda-vakawanda. nzira vharafu spool. Nzira ina kana dzakawanda-nzira screw cartridge proportional mavharuvhu anogona kudzorwa ega kune inoshanda mudziyo
