Ma hydraulic pump solenoid valve excavator loader Chalk 207-6809

Kusiyana pakati pa valavu yamagetsi yamagetsi ndi valavu ya solenoid

Kuwongolera kwa ma valve kumatha kugawidwa m'mitundu iwiri:
 

Imodzi ndi kusintha kosintha: mwina kutseguka kwathunthu kapena kutsekedwa kwathunthu, kuthamanga kwake kumakhala kokwanira kapena kocheperako, palibe gawo lapakati, monga ma elekitirodi wamba kudzera mu valavu, valavu yosinthira ma elekitirodi, valavu yosinthira ma elekitirodi hayidiroliki. Zina ndikuwongolera mosalekeza: doko la valve likhoza kutsegulidwa malinga ndi kufunikira kwa digiri iliyonse yotsegulira, potero kulamulira kukula kwa kutuluka, ma valve oterowo ali ndi ulamuliro pamanja, monga ma throttle valves, komanso amawongoleredwa pakompyuta, monga molingana. ma valve, ma servo valves. Chifukwa chake cholinga chogwiritsa ntchito valavu yofananira kapena valavu ya servo ndi: kukwaniritsa kuwongolera koyenda ndi kuwongolera zamagetsi (zowona, pambuyo pakusintha kwadongosolo kungathenso kuwongolera kuthamanga, etc.), popeza ndikuwongolera, payenera kukhala kutaya mphamvu, servo. valavu ndi ma valve ena ndi osiyana, kutaya mphamvu zake kumakhala kwakukulu, chifukwa kumafunika kuyenda kwina kuti kusungitse ntchito ya pre-siteji control mafuta dera.
Electromagnetic valve (Electromagnetic valve) ndi ntchito yamagetsi yamagetsi

Mfundo yogwira ntchito ya proportional solenoid valve
 

Electro-hydraulic proportional valve ndi chizindikiro chofananira chamagetsi chamagetsi mu valavu kuti ipangitse zomwe zikuyenda, kotero kuti valavu yogwira ntchito imasuntha, wolamulira pakamwa valavu.
Ma inchi amasintha motero amamaliza kukakamiza, kutulutsa kotulutsa kolingana ndi mphamvu yolowera. Kusamuka kwa Spool kumathanso kukhala makina, ma hydraulic kapena
Fomu yamagetsi kuti muyankhe. Electro-hydraulic proportional valve ili ndi mitundu yosiyanasiyana, yosavuta kupanga kugwiritsa ntchito magetsi ndi makompyuta pamakina osiyanasiyana a electro-hydraulicDongosolo, kulondola kwambiri kuwongolera, kuyika kosinthika ndi kugwiritsa ntchito, kuthekera kolimba kotsutsana ndi kuipitsa ndi zabwino zina, gawo logwiritsira ntchito likukulirakulira tsiku ndi tsiku. Kafukufuku waposachedwa ndi chitukukoKupanga ma plug-in proportional valves ndi proportional multi way mavavu amaganizira mozama za kugwiritsa ntchito makina omangira, okhala ndi chiwongolero cha oyendetsa, kuzindikira katundu ndi kukakamiza.Malipiro ndi ntchito zina. Ndikofunikira kwambiri kukonza luso lonse lamakina amtundu wa hydraulic. Makamaka oyendetsa ndege,Kuwongolera kwakutali kopanda zingwe ndi ma waya akutali kwawonetsa chiyembekezo chabwino chogwiritsa ntchito.
