393000M024 Excavator hydraulic pump solenoid valve proportional solenoid valve 3768317

Musiyano uripo pakati pemagetsi proportional valve uye solenoid valve

Valve control yekuyerera inogona kukamurwa kuva marudzi maviri:
 

Imwe ndeye switch control: ingave yakavhurika zvizere kana kuvharwa zvakazara, chiyero chekuyerera chingave chepamusoro kana kushoma, hapana nzvimbo yepakati, seyakajairwa magetsi kuburikidza nevharuvhu, electromagnetic reversing valve, electro-hydraulic reversing valve.Imwe yacho inoramba ichidzora: chiteshi chevhavha chinogona kuvhurwa zvichienderana nekudiwa kwechero dhigirii rekuvhura, nekudaro kudzora saizi yekuyerera kuburikidza, mavharuvhu akadaro ane manyorero ekutonga, senge throttle mavharuvhu, asi zvakare anodzorwa nemagetsi, senge proportional. mavharuvhu, servo mavharuvhu.Saka chinangwa chekushandisa proportional valve kana servo valve ndeye: kuwana kuyerera kwekutonga nemagetsi kutonga (zvechokwadi, mushure mekuchinja kwemaitiro kunogonawo kuwana kudzvinyirira kutonga, nezvimwewo), sezvo iri throttling control, panofanira kuva nekurasikirwa kwesimba, servo. vharafu nemamwe mavharuvhu akasiyana, kurasikirwa kwayo kwesimba kwakakura, nekuti inoda kumwe kuyerera kuchengetedza basa reiyo pre-stage control oil circuit.
Electromagnetic valve (Electromagnetic valve) iko kushandiswa kwemagetsi emagetsi

Kushanda nheyo yeproportional solenoid valve
   

Electro-hydraulic proportional valve ndiyo proportional electromagnet input voltage signal muvharuvhu kuti ibudise chiito chinoenderana, kuitira kuti vharafu inoshanda spool displacement, valve port size shanduko uye kupedzisa kumanikidza uye kuyerera kwezvinobuda zvikamu zvinoenderana neiyo voltage yekupinza.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 mutyairi wekutyaira, kunzwa mutoro uye kumanikidza muripo mabasa.Izvo zvakakosha zvikuru kuvandudza iyo yakazara tekinoroji level ye mobile hydraulic muchina.
