I-excavator yempompo ye-hydraulic ye-proportional solenoid valve 200-6210

I-spool ye-valve ye-solenoid ehambelanayo ilawulwa yi-electromagnets elinganayo, ukwenzela ukuba uxinzelelo lwemveliso okanye ukuhamba kuhambelane negalelo langoku. Ngoko ke, uxinzelelo lwemveliso okanye ukuhamba kunokulawulwa ngokuqhubekayo ngokutshintsha isignali yokufaka. Ezinye iivalvu zikwanawo nomsebenzi wokulawula ubungakanani bokuhamba kunye nesalathiso. Ngokwevalufa yolungelelwaniso isenokwahlulwa ibe: ivelufa yomlinganiselo woxinzelelo, ivalve elinganayo, ivalve yokulungelelanisa, ivalve yokubuyisela umva iindidi ezintathu.
Ivalve elinganiselayo isetyenziselwa ukutshintsha indawo yolawulo lokuqala kunye ne-electromagnetic electromagnet kwivalve eqhelekileyo yoxinzelelo, ivalve yokuqukuqela kunye nevalve yendlela, kunye nokulawula ukude uxinzelelo, ukuhamba okanye icala lokuhamba kwe-oyile ngokwesiginali yombane ngokuqhubekayo nangokulinganayo. . Iivalve ezilinganayo ngokubanzi zinomsebenzi wembuyekezo yoxinzelelo, kwaye uxinzelelo lwemveliso kunye nesantya sokuhamba asinakuchaphazeleka ngotshintsho lomthwalo.
Ivalve elinganayo inokulawula ubungakanani bemveliso kunye ne-PWM wave, kwaye imveliso iyaqhubeka.
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.
