Ivalve yoncedo i-PC220-6 Ivalve yokhuseleko ye-Excavator 708-2L-04740

Kukho iintlobo ezininzi zeevalvu ze-solenoid kwii-excavators ezincinci. Okokuqala, kufuneka sazi umgaqo osebenzayo wevalve ye-solenoid. Ivalve ye-solenoid yoomatshini bokugrumba isebenzisa umazibuthe we-electromagnetic ukutyhala undoqo wevalve ukulawula icala lomoya ocinezelekileyo, ukuze kulawulwe icala lokutshintsha kwe-pneumatic actuator. Ivalve ye-electromagnetic directional valve ngokweemfuno ezahlukeneyo inokufezekisa iindlela ezimbini ezintathu, ezimbini-ezintlanu njalo njalo
Okokuqala, isakhiwo sevalve ye-solenoid: i-coil, imagnethi, intonga ye-ejector.

Umgaqo osebenzayo wevalve ye-solenoid ye-excavator encinci kukuba xa ikhoyili idityaniswe ne-current, yenza i-magnetism, itsalelane kunye nemagnethi, imagnethi idonsa intonga ye-ejector, icime amandla, i-magnet kunye ne-ejector rod. zisetwa ngokutsha, kwaye inkqubo yokusebenza igqityiwe.

Okwesibini, i-electromagnetic esetyenziselwa ukusebenzisa ivalve ye-solenoid kwi-excavator encinci yahlulwe ibe yi-AC kunye ne-DC.

Umbane we-electromagnetic ye-AC ngokubanzi yi-220V, ebonakaliswa ngamandla amakhulu okuqalisa, ixesha elifutshane lokubuyisela umva kunye nexabiso eliphantsi. Nangona kunjalo, xa undoqo wevalve ungabambekanga ngokwaneleyo kwaye umbindi wentsimbi awufunxwanga, i-electromagnetic kulula ukutshisa ngenxa yangoku ngokugqithisileyo, ngoko ke ukusebenza okunokwenzeka kumbi, isenzo sinempembelelo, kwaye ubomi bufutshane. Umbane we-electromagnetic ye-DC ngokubanzi yi-24V, kwaye inzuzo yayo kukuba isebenza ngokuthembekileyo, ayiyi kutshisa ngenxa ye-spore enamathelayo, kwaye inobomi obude.

Okwesithathu, ukuhlelwa kweevalvu ze-solenoid

I-1, ivalve ye-solenoid esebenza ngokuthe ngqo
Xa amandla evuliwe, amandla e-electromagnetic aveliswa yikhoyili ye-electromagnetic iphakamisa iqhekeza lokuvala ukusuka esihlalweni, kwaye ivalve ibizwa ngokuba. Xa amandla ecinyiwe, i-valve ye-solenoid iyanyamalala, i-spring icinezela inxalenye yokuvala esihlalweni, kwaye i-valve ivaliwe. Ibonakala ngokusebenza okuqhelekileyo kwi-vacuum, uxinzelelo olubi kunye noxinzelelo lwe-zero, kodwa ububanzi ngokuqhelekileyo abukho ngaphezu kwe-25mm.

2, ivalve ye-solenoid yokulinga
(Umgaqo-siseko wokusebenza kwevalve ye-solenoid)

Xa ilayitiwe, amandla ombane wombane avula umngxuma wokulingwa, uxinzelelo lwegumbi eliphezulu lwehla ngokukhawuleza, lwenza umahluko ophantsi nophezulu woxinzelelo ojikeleze indawo yokuvala, uxinzelelo lolwelo lutyhala indawo yokuvala ukuba iye phezulu, kwaye ivalve ivuleke. Xa umbane ecinyiwe, amandla entwasahlobo avala umngxuma wokulingwa, kwaye uxinzelelo lokungena ludala umahluko ophantsi nophezulu woxinzelelo olujikeleze indawo yokuvala ivalve ngomngxuma odlulayo ngokukhawuleza, kwaye uxinzelelo lolwelo lutyhala indawo yokuvala ukuba yehle kwaye ivale ivalve. Ibonakaliswe ngumda ophezulu ophezulu woluhlu loxinzelelo lwe-fluid kwaye ingafakelwa ngaphandle kwesizathu (ukuba ilungiselelwe) kodwa kufuneka ihlangabezane neemeko zokwahlukana koxinzelelo lwe-fluid.
