TM1005110 24V excavator hydraulic futha proportional valve solenoid

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

I-valve ye-Proportional kanye nomehluko we-solenoid valve

  I-valve ye-Proportional wuhlobo olusha lwedivayisi yokulawula amanzi. Ku-valve yokucindezela evamile, i-valve yokugeleza kanye ne-valve yokuqondisa, i-electromagnetic electromagnet isetshenziselwa ukufaka esikhundleni sengxenye yokulawula yasekuqaleni, futhi ingcindezi, ukugeleza noma isiqondiso sokugeleza kukawoyela kulawulwa ukude ngokuya ngesignali kagesi yokufaka ngokuqhubekayo nangokulingana. Ama-valve alinganiselayo ngokuvamile anokusebenza kwesinxephezelo sokucindezela, futhi ingcindezi yokuphumayo nezinga lokugeleza akukwazi ukushintshwa umthwalo womthelela woshintsho.

I-1, i-valve evamile ayikwazi ukulingana nokulawula isinyathelo esiqhubekayo, i-valve yesenzo esisodwa esihlanzekile sohlobo lokushintsha, isiqondiso sokuvula i-valve, inani lokuvula noma amandla okusetha entwasahlobo aqinisekile, awakwazi ukushintsha ngokuvumelana nesimo sangempela.

I-2, i-valve ye-proportional ilingana nokulawulwa kwesinyathelo esiqhubekayo, ngokusho kwesimo sangempela izinguquko kulwazi oluqoqwe emuva ekuqondisweni kwesinxephezelo esizenzakalelayo, isiqondiso sokuvula i-valve, inani lokuvula noma amandla okusetha kwentwasahlobo ayalandelwa, ukuze kuzuzwe uchungechunge okuqhubekayo izinguquko ezilawulekayo esenzweni.
