ZAXIS240-3 Reverse proportional solenoid valve excavator iindawo zepompo yehydraulic

Umgaqo-siseko wokusebenza kwevalvu ye-electromagnetic kunye nokufunyanwa:

Ulawulo lwevalve lokuhamba lunokwahlulwa lube ziindidi ezimbini:
Olunye lulawulo lokutshintsha: nokuba luvuleke ngokupheleleyo okanye luvalwe ngokupheleleyo, izinga lokuqukuqela linokuba likhulu okanye lincinci, akukho mbuso uphakathi, njengesiqhelo sombane we-electromagnetic ngokusebenzisa iivalvu, i-electromagnetic reversing valves, i-electro-hydraulic reversing valves.
Olunye lulawulo oluqhubekayo: i-valve port inokuvulwa ngokwesidingo salo naliphi na iqondo lokuvula, ngaloo ndlela ilawula ubungakanani bokuqukuqela, iivalvu ezinjalo zinolawulo lwezandla, olufana ne-throttle valves, kodwa zilawulwa nge-elektroniki, ezifana nokulinganisa. iivalve, iivalve zeservo.
Ke injongo yokusebenzisa ivalve elinganayo okanye ivalve ye-servo yile: ukufezekisa ulawulo lokuhamba ngolawulo lwe-elektroniki (ewe, emva kokuba utshintsho lwesakhiwo lunokufikelela kulawulo loxinzelelo, njl.njl.), kuba lulawulo lokuthomalalisa, kufuneka kubekho ukulahleka kwamandla, i-servo. i-valve kunye nezinye iivalve zihluke, ukulahlekelwa kwayo kwamandla kukhulu, kuba idinga ukuhamba okuthile ukuze kugcinwe umsebenzi wesiphaluka sokulawula i-oyile yangaphambili.

Ubume kunye nomgaqo wokusebenza wevalve ye-solenoid

Ivalve ye-solenoid luhlobo lokutshintsha olunokulawula ulwelo ngokwesenzo sokutshintsha kombane wesekethe yolawulo, kwaye inokulungelelanisa ukuhamba ngokutshintsha ubungakanani bombane. I-valve ye-Solenoid isoloko isetyenziselwa ulwelo, ukulawula ukuhamba kwegesi, ukuguqulwa kunye nokulawula uxinzelelo, yinto ebalulekileyo yokuzenzekelayo.
Ivalve ye-Solenoid ikakhulu yenziwe ngumzimba wevalve, undoqo wevalve, isiqu sevalve, ikhoyili ye-solenoid, undoqo wentsimbi, isilawuli kunye namanye amalungu. Umzimba we-valve uyisakhiwo esijikelezayo, esinentloko yokudibanisa kunye ne-groove okanye umngxuma, esetyenziselwa ukudibanisa umbhobho we-fluid, kunye ne-coil ye-electromagnetic kunye nomlawuli zifakwe ngaphandle: i-spool iyona nxalenye ephambili yolawulo lwangoku, indima yayo. kukwamkela ulawulo lwangoku, ukuze isikhondo sevalve sihambe, ngaloo ndlela sitshintsha isidanga sokuvula sevalve; Isiqu sevalve yishafti edibanisa undoqo wevalve kunye nevalve, esetyenziselwa ukuhambisa amandla okusebenza alawulwa yicoil ye-electromagnetic coil; Ikhoyili ye-solenoid sisixhobo esiphambili sokulawula ukuhamba kwe-valve ye-solenoid, kwaye i-voltage yayo yokusebenza kunye namandla inokulawulwa ngokweemfuno zenkqubo yokulawula kwisiphaluka se-fluid. I-iron core yinto yamagnetic kwi-coil ye-electromagnetic, enokuphucula amandla ombane wekhoyili, ngaloo ndlela ikhulise ukusebenza kakuhle kokuvula nokuvala; Umlawuli sisixhobo sokuqonda ukulawulwa kokuhamba, oqonda injongo yolawulo ngokuguqula ubungakanani bangoku.
