I-valve yokusiza i-PC220-6 I-valve yokuphepha ye-Excavator 708-2L-04740

Kunezinhlobo eziningi zamavalvu e-solenoid kuma-excavators amancane. Okokuqala, kufanele sazi isimiso sokusebenza se-valve ye-solenoid. I-valve ye-solenoid yomshini wokumba isebenzisa i-electromagnetic ukusunduza umgogodla we-valve ukulawula ukuqondiswa komoya ocindezelweyo, ukuze ulawule ukuqondiswa kweswishi ye-pneumatic actuator. I-valve ye-electromagnetic directional valve ngokwezidingo ezahlukene ingakwazi ukufeza izindlela ezimbili ezintathu, ezimbili ezinhlanu njalonjalo
Okokuqala, ukwakheka kwe-valve ye-solenoid: ikhoyili, uzibuthe, induku ye-ejector.

Isimiso sokusebenza se-valve ye-solenoid ye-excavator encane ukuthi lapho ikhoyili ixhunywe ne-current, ikhiqiza i-magnetism, idonselana ngozibuthe, i-magnet idonsa induku ye-ejector, ivala amandla, i-magnet ne-ejector rod. asethwe kabusha, futhi inqubo yokusebenza iyaqedwa.

Okwesibili, i-electromagnetic esetshenziselwa ukusebenzisa i-valve ye-solenoid ku-excavator encane ihlukaniswe i-AC ne-DC.

Amandla kagesi kazibuthe we-AC ngokuvamile angu-220V, abonakala ngamandla amakhulu okuqala, isikhathi esifushane sokubuyisela emuva kanye nenani eliphansi. Kodwa-ke, lapho i-valve core ingabambeki ngokwanele futhi i-iron core ingamuncwa, i-electromagnetic kulula ukuvutha ngenxa yamanje kakhulu, ngakho-ke amathuba okusebenza ampofu, isenzo sinomthelela, futhi ukuphila kufushane. I-voltage ye-electromagnetic ye-DC ngokuvamile ingu-24V, futhi inzuzo yayo ukuthi isebenza ngokwethembeka, ngeke iphele ngenxa yokunamathela kwesipore, futhi inempilo ende.

Okwesithathu, ukuhlukaniswa kwama-valve e-solenoid

1, i-valve ye-solenoid esebenza ngokuqondile
Lapho amandla evuliwe, amandla kazibuthe kagesi akhiqizwe ikhoyili kagesi aphakamisa ucezu oluvalayo esihlalweni, bese kuthiwa ivalvu. Lapho amandla evaliwe, i-valve ye-solenoid iyanyamalala, intwasahlobo icindezela ingxenye yokuvala esihlalweni, futhi i-valve ivaliwe. Ibonakala ngokusebenza okuvamile ku-vacuum, ingcindezi engalungile kanye nengcindezi ye-zero, kodwa ububanzi ngokuvamile abudluli ku-25mm.

2, umshayeli we-solenoid valve
(Isimiso sokusebenza se-pilot solenoid valve)

Lapho ikhanya, amandla kazibuthe kagesi avula imbobo yokushayela, umfutho wegumbi eliphezulu wehla ngokushesha, wenze umehluko ophansi nophezulu wokucindezela engxenyeni evalayo, umfutho woketshezi uphusha ingxenye evalayo ukuze iye phezulu, bese ivalvu ivuleka. Lapho amandla ecishiwe, amandla asentwasahlobo avala imbobo yokushayela, futhi ukucindezela kokungena kwenza umehluko wengcindezi ephansi nephezulu ezungeze ingxenye evala i-valve ngembobo yokudlula ngokushesha, futhi umfutho woketshezi uphusha ingxenye evalayo ukuze yehle futhi ivale i-valve. Ibonakala ngomkhawulo ophezulu ophezulu webanga lokucindezela koketshezi futhi ingafakwa ngokungenasisekelo (ukuze yenziwe ngendlela oyifisayo) kodwa kufanele ihlangabezane nezimo zomehluko wengcindezi yoketshezi.
