Umlayishi excavator izixhobo XKCH-00022 solenoid valve Hydraulic valve

Uthini umahluko phakathi kwevalve elinganayo kunye nevalve eqhelekileyo ye-solenoid?

Ivalve elinganayo luhlobo olutsha lwesixhobo sokulawula amanzi. Kwivalve yesiqhelo yoxinzelelo, ivalve yokuqukuqela kunye nevalve yendlela, i-electromagnetic elinganayo isetyenziselwa ukubuyisela indawo yolawulo lwangaphambili, ngokombane wegalelo.
Umqondiso werhasi ngokuqhubekayo nangokulinganayo ulawula uxinzelelo, ukuhamba, okanye icala lomsinga weoyile ukude. Iivalvu ezilinganayo ngokubanzi zinomsebenzi wembuyekezo yoxinzelelo, kwaye uxinzelelo lwemveliso kunye nesantya sokuhamba asinakuchaphazeleka lutshintsho lomthwalo.

I-1, ivalve yesiqhelo ayilingani nolawulo lwenyathelo oluqhubekayo, yivalve yokutshintsha uhlobo olulodwa lwesenzo, indlela yokuvula ivalve, isixa sokuvula okanye amandla okusetwa kwentwasahlobo aqinisekileyo.
Ayinakutshintshwa ngokweemeko zokwenyani.

I-2, ivalve ehambelanayo ilingana nolawulo lwenyathelo oluqhubekayo, ngokweyona meko itshintshayo kulwazi oluqokelelweyo kulawulo oluzenzekelayo lwembuyekezo ekujoliswe kuyo, indlela yokuvula ivalve, isixa sokuvula okanyei-spring set force ilandelwa, ukufezekisa uchungechunge lweenguqu eziqhubekayo ezilawulwayo ekuhambeni. Ulawulo lokuhamba kwevalve lunokwahlulwa lube ziindidi ezimbini: enye kulawulo lokutshintsha: nokuba luvuleke ngokupheleleyo, okanye luvalwe ngokupheleleyo, ukuhambahamba nokuba, okanye kuncinci, akukho meko ephakathi, njengesiqhelo sombane ngevalve, ivalve yokubuyisela umbane ye-electromagnetic, i-electro-hydraulic reversing. ivalve. 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.

Umgaqo wokusebenza wevalufa yomlinganiselo:

Umqondiso womyalelo ukhuliswa yi-proportional amplifier, kunye ne-proportional output yangoku ukuya kwiproportional solenoid yevalve ehambelanayo, i-proportional solenoid yamandla ephumayo kunye nokuhamba ngokulinganayo kwendawo engundoqo yevalve, unokulawula ngokulinganayo ukuhamba kolwelo kunye tshintsha isalathiso sokuhamba kolwelo, ukuze ufezekise indawo okanye ulawulo lwesantya se-actuator. Kwezinye izicelo ezifuna isikhundla esiphezulu okanye ukuchaneka kwesantya, inkqubo yokulawula i-loop evaliweyo inokusekwa ngokufumanisa ukukhutshwa okanye isantya se-actuator.
Ivalve yolungelelwaniso yenziwe yi-DC yombane wokulinganisa we-electromagnetic kunye nevalve yehydraulic. Undoqo wevalve elinganayo ukuqonda ulawulo oluqhubekayo ngumlinganiselo
Kukho iintlobo ezininzi zee-electromagnets ezilinganayo, kodwa umgaqo wokusebenza uyafana, zonke ziphuhliswa ngokweemfuno zolawulo lwevalve elinganayo.
