I-Excavator solenoid valve 21P-60-K5160 Hydraulic solenoid valve ifanele i-Komatsu PC150-6 PC160-6

Ukusetshenziswa kwe-valve ye-solenoid elinganayo
 

Ukulawula izinga le-liquid ngokucindezela Enye indlela yokulawula izinga ukulawula ukucindezela kwegesi ngaphezu kwezinga le-liquid. Ngokusebenzisa ama-valve e-solenoid amabili alinganayo, isilawuli se-PID sinikeza umoya owanele (i-nitrogen kulesi simo) ukugcina ukucindezela ngaphezu kwezinga loketshezi kungashintshi ngaso sonke isikhathi (njengoba izinga le-liquid lehla, kanjalo nokucindezela kwegesi). Ukulawula ukugeleza Ama-valve e-solenoid alinganayo asetshenziswa ngokuqondile ukulawula isishisi sokugeleza/Ukulawula ilangabi Uhlelo lokulawula izishisi kufanele lulawule amagesi amabili. La magesi amabili axutshwe ngesilinganiso esithile. Isilinganiso segesi evuthayo negesi ye-oxidation (umoya noma umoya-mpilo) sinqunywa ngokuhambisana nobukhulu belangabi elidingekayo ngenqubo ngayinye yokuvutha.

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.  

Umgomo oyinhloko we-proportional solenoid valve ukuthi isignali yokulawula ukugeleza namandla okulawula asetshenziswa njengomthombo wamandla wekhoyili kagesi, ukuze i-electromagnetic ilawule ukuvulwa kwe-valve, ngakho ukuvulwa kwe-valve kucishe kulingane usayizi wesiginali yokulawula ukugeleza.

Ngokuhambisana nokugeleza okuhlukile, indawo yokulawula ngayinye inenani elihlukile lokugeleza, elibuyiselwa kusilawuli sokugeleza, isilawuli sokugeleza singakwazi ukulungisa indawo ye-valve ngokusho kwesignali yokuphuma yesayizi efanayo nokugeleza lapha, ukuze ukufeza izidingo zokulawula ezinembile.

Umgomo wokulawula we-valve ye-solenoid elinganayo inezici ezintathu eziyinhloko: okokuqala, ukuguquguquka kwesignali kagesi kuthinta izinga lokuvula le-valve;
