I-Hydraulic pump solenoid valve excavator loader izesekeli 207-6809

Umehluko phakathi kwe-valve ye-proportional kagesi ne-solenoid valve

Ukulawulwa kwe-valve kokugeleza kungahlukaniswa ngezinhlobo ezimbili:
 

Okukodwa ukulawulwa kokushintsha: kungaba kuvuleke ngokuphelele noma kuvalwe ngokugcwele, izinga lokugeleza liphezulu noma lincane, asikho isimo esimaphakathi, esifana ne-electromagnetic through valve, electromagnetic reversing valve, electro-hydraulic reversing valve. Okunye ukulawulwa okuqhubekayo: imbobo ye-valve ingavulwa ngokwesidingo sanoma yiliphi izinga lokuvula, ngaleyo ndlela ilawule ubukhulu bokugeleza, ama-valve anjalo anokulawula okubhaliwe, njengama-throttle valve, kodwa futhi alawulwa nge-elekthronikhi, njenge-proportional. ama-valve, ama-servo valves. Ngakho-ke inhloso yokusebenzisa i-valve ye-proportional noma i-valve ye-servo iwukuthi: ukufeza ukulawulwa kokugeleza ngokulawulwa kwe-elekthronikhi (yebo, ngemuva kwezinguquko zesakhiwo nakho kungafinyelela ukulawulwa kwengcindezi, njll.), njengoba kungukulawula okudonsayo, kufanele kube nokulahlekelwa kwamandla, i-servo. i-valve namanye ama-valve ahlukile, ukulahlekelwa kwawo kwamandla kukhulu, ngoba kudinga ukugeleza okuthile ukuze kugcinwe umsebenzi wesifunda samafutha okulawula isigaba sangaphambi kwesiteji.
I-valve ye-electromagnetic (i-electromagnetic valve) ukusetshenziswa kwe-electromagnetic valve

Isimiso sokusebenza se-proportional solenoid valve
 

I-electro-hydraulic proportional valve iyisiginali ye-electromagnetic input voltage input in valve ukuze ikhiqize isenzo esihambisanayo, ukuze i-valve esebenzayo igudluke, irula yomlomo we-valve.
I-intshi iyashintsha futhi ngaleyo ndlela iqedele ukucindezela, into ephumayo yokugeleza ngokulingana ne-voltage yokufaka. I-Spool displacement ingaba ngomshini, i-hydraulic noma
Ifomu likagesi ukuze uthole impendulo. I-electro-hydraulic proportional valve inezinhlobonhlobo zezinhlobo, kulula ukwenza ukusetshenziswa kokulawula ugesi kanye nekhompyutha yesistimu ehlukahlukene ye-electro-hydraulic.Uhlelo, ukunemba kokulawula okuphezulu, ukufakwa nokusetshenziswa okuguquguqukayo, ikhono eliqinile lokulwa nokungcola nezinye izinzuzo, inkambu yesicelo iyanda usuku nosuku. Ucwaningo nentuthuko yakamuvaUkukhiqizwa kwama-plug-in proportional valves kanye nama-proportional multi way valves kucabangela ngokugcwele izici zokusetshenziswa kwemishini yokwakha, enokulawula umshayeli, ukuzwa komthwalo kanye nengcindezi.Isinxephezelo neminye imisebenzi. Kubaluleke kakhulu ukwenza ngcono izinga lobuchwepheshe bemishini esebenza ngogesi ephathwayo. Ukusebenza komshayeli olawulwa nge-elekthronikhi,Isilawuli kude esingenantambo nokusebenza kwesilawuli kude esinentambo kubonise ithuba elihle lohlelo lokusebenza.
