TM85402 24V excavator hydraulic futha proportional isolenoid valve loader izesekeli

Ukuhlaziywa kwe-valve ye-proportional pressure kanye nokuqedwa ngenxa yokuthi i-valve ye-proportional pressure isekelwe nje nge-valve yokucindezela evamile, isibambo somlawuli sithathelwa indawo yi-proportional electromagnet.

Ngakho-ke, amaphutha ahlukahlukene abangelwa i-valve yokucindezela evamile, ezophinde ikhiqize iphutha elivamile le-valve yokucindezela nezindlela zokuqeda nazo zisebenza ngokugcwele ku-valve ye-proportional pressure ehambisanayo (njenge-valve yesifazane echichimayo ehambisana ne-proportional relief valve), ingadluliselwa. kuya ukuze kucutshungulwe.  

Inqubo yokusebenza ye-proportional solenoid valve ingafingqwa njengezinyathelo ezine.

Okokuqala, ukunikezwa kwamandla kuhlala kuzinzile, bese isiginali yokulawula ngokulinganayo itholwa kusilawuli futhi idluliselwe ku-i-valve ye-solenoid elinganayo;

Okwesibili, isignali yokulawula ngokulinganayo iguqulwa ibe i-electromagnetic force excitation, ngaleyo ndlela ilawula ukujikeleza kwe-valve;

Okwesithathu, ngokusho kokujikeleza kwe-valve ukulawula izinga lokuvula le-valve, bese impendulo kumlawuli;

Okwesine, ngokusho kwesignali yempendulo ukulungisa isiphethu se-valve, ukuze kuzuzwe ukulawula okunembile kwedigri yokuvula i-valve.

Umgomo wokulawula we-proportional solenoid valve unezici ezintathu eziyinhloko:

Okokuqala, ukushintshashintsha kwesignali kagesi kuthinta izinga lokuvula le-valve;

Okwesithathu ukulawula izinga lokuvula le-valve ngokuya ngokuzungezisa kwe-valve, bese udlulisela iluphu yesignali yempendulo kusilawuli sokugeleza ukuze kuzuzwe ukulawula ukugeleza.
