I-ZAXIS240-3 Reverse proportional solenoid valve excavator izingxenye zephampu ye-hydraulic

Isimiso sokusebenza kwe-electromagnetic proportional valve kanye nokutholwa:

Ukulawulwa kwe-valve kokugeleza kungahlukaniswa ngezinhlobo ezimbili:
Eyodwa ukulawulwa kokushintsha: kungaba kuvuleke ngokuphelele noma kuvalwe ngokugcwele, izinga lokugeleza likhulu noma lincane, asikho isimo esimaphakathi, esifana ne-electromagnetic evamile ngamavalvu, ama-electromagnetic reverse valves, ama-electro-hydraulic reversing valves.
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.

Isakhiwo kanye nesimiso sokusebenza se-valve ye-solenoid

I-valve ye-solenoid iwuhlobo lokushintshwa olungakwazi ukulawula uketshezi ngokuya ngesenzo sokushintsha i-voltage yesifunda sokulawula, futhi ingalungisa nokugeleza ngokushintsha usayizi we-voltage. I-valve ye-Solenoid ivame ukusetshenziswa ku-liquid, ukulawulwa kokugeleza kwegesi, ukuguqulwa nokulawulwa kwengcindezi, kuyingxenye ebalulekile ye-automation.
I-valve ye-Solenoid ikakhulukazi yakhiwa umzimba we-valve, i-valve core, i-valve stem, ikhoyili ye-solenoid, i-iron core, isilawuli nezinye izingxenye. Umzimba we-valve uyisakhiwo esiqhamukayo, esinekhanda lokuxhuma eline-groove noma imbobo, esetshenziselwa ukuxhuma ipayipi le-fluid, futhi ikhoyili kagesi kanye nesilawuli sifakwe ngaphandle: i-spool iyingxenye eyinhloko yamanje yokulawula, indima yayo. ukwamukela isilawuli samanje, ukuze isiqu se-valve sinyakaze, ngaleyo ndlela siguqule izinga lokuvula le-valve; Isiqu se-valve i-shaft exhuma umgogodla we-valve kanye ne-valve, esetshenziselwa ukudlulisa amandla okusebenza alawulwa ikhoyili kagesi; Ikhoyili ye-solenoid iyithuluzi eliyisihluthulelo lokulawula ukugeleza kwe-valve ye-solenoid, futhi i-voltage yayo yokusebenza namandla kungalawulwa ngokuvumelana nezidingo zesistimu yokulawula kumjikelezo we-fluid. I-iron core iyinto yamagnetic ku-coil ye-electromagnetic, engathuthukisa amandla kazibuthe wekhoyili, ngaleyo ndlela ikhulise ukusebenza kahle kokuvula nokuvala; Isilawuli siyithuluzi lokubona ukulawulwa kokugeleza, oqaphela inhloso yokulawula ngokushintsha usayizi wamanje.
