TM1005110 24V excavator hayidiroliki mpope proportional solenoid valavu

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

Kusiyana kwa valve ndi solenoid valve

  Proportional valve ndi mtundu watsopano wa chipangizo chowongolera ma hydraulic. Mu valavu yamagetsi wamba, valavu yothamanga ndi valavu yolowera, ma electromagnet wofananira amagwiritsidwa ntchito m'malo mwa gawo loyang'anira, ndipo kukakamiza, kuyenda kapena mayendedwe akuyenda kwamafuta kumayendetsedwa patali molingana ndi chizindikiro chamagetsi cholowera mosalekeza komanso molingana. Ma valve ofananira nthawi zambiri amakhala ndi chiwongola dzanja, ndipo kuthamanga kwa kutuluka ndi kuthamanga kwa kuthamanga sikungasinthidwe ndi katundu wakusintha.

1, valavu wamba sangakhale wolingana ndi kuwongolera kopitilira muyeso, ndi valavu yoyera imodzi yosinthira, njira yotsegulira valavu, kuchuluka kotsegulira kapena mphamvu yoyika masika ndizotsimikizika, sizingasinthe malinga ndi momwe zilili.

2, valavu proportional ndi molingana ndi kulamulira masitepe mosalekeza, malinga ndi mmene zinthu zilili kusintha mfundo anasonkhanitsa kubwerera chandamale basi chipukuta misozi ulamuliro, valavu kutsegula malangizo, kutsegula kuchuluka kapena kasupe kukhazikitsa mphamvu akutsatiridwa, kukwaniritsa angapo mosalekeza. kusintha kosinthika muzochita.
