ZAXIS240-3 Reverse proportional solenoid valve excavator hydraulic pump

Electromagnetic proportional valve ntchito mfundo ndi kuzindikira:

Kuwongolera kwa ma valve kumatha kugawidwa m'mitundu iwiri:
Imodzi ndi kusintha kosintha: mwina kutseguka kwathunthu kapena kutsekedwa kwathunthu, kuchuluka kwa kuthamanga kumakhala kwakukulu kapena kochepa, palibe gawo lapakati, monga ma elekitiroma wamba kudzera mu mavavu, ma valve osinthira ma elekitiroma, ma electro-hydraulic reversing valves.
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.

Kamangidwe ndi mfundo ntchito ya valavu solenoid

Valavu ya solenoid ndi mtundu wosinthira womwe umatha kuwongolera madziwo molingana ndi kusintha kwa magetsi a dera lowongolera, komanso kusintha kayendedwe kake posintha kukula kwa voteji. Valavu ya Solenoid nthawi zambiri imagwiritsidwa ntchito mumadzimadzi, kuyendetsa gasi, kutembenuka ndi kuwongolera kuthamanga, ndi gawo lofunikira lodzipangira.
Valavu ya Solenoid imapangidwa makamaka ndi thupi la valavu, maziko a valavu, tsinde la valavu, koyilo ya solenoid, pachimake chachitsulo, chowongolera ndi mbali zina. Thupi la valavu ndi mawonekedwe otuluka, omwe ali ndi mutu wolumikizana ndi poyambira kapena dzenje, lomwe limagwiritsidwa ntchito kulumikiza payipi yamadzimadzi, ndipo koyilo yamagetsi yamagetsi ndi chowongolera amayikidwa panja: spool ndiye gawo lalikulu lakuwongolera pano, udindo wake. ndi kuvomereza kulamulira panopa, kuti tsinde valavu kusuntha, potero kusintha kutsegulira digiri ya valavu; Tsinde la valavu ndi tsinde lomwe limalumikiza pachimake cha valve ndi valavu, yomwe imagwiritsidwa ntchito kuwonetsa mphamvu yoyendetsera ntchito yoyendetsedwa ndi koyilo yamagetsi; Chophimba cha solenoid ndi chipangizo chofunikira kwambiri chowongolera kuthamanga kwa valve ya solenoid, ndipo mphamvu yake yogwira ntchito ndi mphamvu zimatha kuwongoleredwa malinga ndi zofunikira za kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe kake. Chitsulo chachitsulo ndi maginito mu coil electromagnetic coil, yomwe imatha kupititsa patsogolo mphamvu ya maginito ya koyilo, motero imawonjezera mphamvu yotsegula ndi kutseka; The regulator ndi chipangizo kuzindikira kayendedwe ka kayendedwe ka kayendedwe ka kayendedwe ka kayendedwe ka kayendedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwekazi ka kayendetsedwe ka kayendetsedwe kamwemwebumwemwe kapanganidwe KA hwe aunganinsombo33jojojojojojojojojojojo zaba kwetu konjinipyapyapyapyapyapyai wowotesiseizokwenikwenikwenikwenikweniKukula kwatsopano.
