Hydraulic solenoid valve ni gaw hka lwi ai lam, n-gun, lwi ai lam ni hpe hkang ai hydraulic system ni hta ahkyak ai arung arai ni rai nga ai. Shanhte gaw, valve core hpe shachyut na matu, wan n-gun hpe lang nna, hydraulic circuit hpe hkrak hkrak hkang lu ai. Shanhte a bungli galaw ai ladat gaw, wan n-gun n-gun (electromagnetic induction) hte hka n-gun (fluid dynamics) hpe kayau kaya galaw ai hta madung tawn nna, shanhte hpe engineering jak rai ni, nhprang sut rai ni, nbungli hte kaga lam ni hta grai lang ma ai.
Madung hkrang hte daw ni
Hydraulic solenoid valve hta madung hku nna valve hkum hkrang, valve a npawt, solenoid coil, spring, hte shinggrup da ai n-gun ni lawm ai. Valve hkum hkrang gaw hka htung hpe jaw ya nna kaga daw ni hpe mung makawp maga ya ai; valve core gaw hka lwi ai hpe hkang ai core shamu shamawt ai daw re. N-gun jaw ai shaloi, solenoid coil gaw magnetic field hpe shabyin ya nna, valve core hpe shachyut ya ai. Dai spring gaw, valve core hpe shawng na shara de bai gram lajang ya ai.

Shanhte a bungli hpe madung tawn nna, solenoid valve ni hpe lam madun ai hkang ai valve (2/2-way hte 3/4-way zawn re ai), n-gun hpe hkang ai valve, hte lwi ai hpe hkang ai valve ngu nna garan ginhka mai ai, lam madun ai hkang ai valve ni gaw grau nna lang ai.
Bungli galaw ai npawt tara hpe hkrak sang lang dan ai
1. Wan n-gun hpe shamu shamawt shangun ai ladat
Solenoid valve a core shadut n-gun gaw solenoid coil kaw na pru wa ai. Coil hpe de-energized galaw ai shaloi, valve core gaw shi a shawng na shara kaw rai nga ai (spring preload hku nna gram lajang da ai), hka lam hpe hpaw da ai (sh) default hku nna pat da ai. Ga shadawn, direct-acting, 2/2-way valve hta, valve core gaw n-gun n rawng ai sha sau htu ai shara ni hpe pat da ai majaw, hka n-gun n pru mat ai. Coil hpe DC (sh) AC power source hte matut da ai shaloi, dai current gaw coil kata kaw magnetic field byin shangun ai. Ndai magnetic n-gun gaw valve core hpe solenoid de gang shadut ya nna, spring a ninghkap ai lam hpe lai di kau ya ai majaw, sau htu ai shara a matut mahkai lam hpe galai shai kau ya ai (ga shadawn, hka lwi wa na matu lam hpaw ya ai).
Pilot-galaw ai solenoid valve ni a matu (n-gun kaba ai, n-gun kaba ai -hka lwi ai lam ni a matu htuk manu ai), kaji ai, hkrak hkrak-galaw ai solenoid valve (pilot valve) gaw, madung valve kata na pilot sau n-gun hpe hkang ai. Pilot valve hpe n-gun jaw ai shaloi, pilot sau n-gun gaw main valve core hpe shamu shamawt shangun nna, dai hku nna main sau lam hpe hpaw, pat kau, shing nrai galai kau ya ai. Ndai hkrang gaw, valve kaba a core hpe hkrak sha galaw na matu ra ai electromagnetic n-gun hpe shayawm ya ai majaw, valve a jai lang mai ai pressure range hpe jat ya lu ai.
2. Valve Core shamu shamawt ai lam hte hka hpe hkang ai lam
Valve core a shara gaw hydraulic hka lwi ai lam hpe hkrak dawdan ya ai. Ga shadawn hku nna, shingra tara hku nna masum- shara, mali- lam solenoid valve hpe la ga:
• Neutral position (normal): Solenoid coil lahkawng yan hpe n-gun n jaw ai sha, valve core hpe spring hte lapran kaw tawn da nna, sau shang ai shara hte sau bai wa ai shara ni hpe matut da ai, actuator a nta lahkawng (hydraulic cylinder zawn re ai) hpe pat da ai, system gaw s naw nga ai.
• Lawu maga na shara (coil A hpe n-gun jaw ai): Lawu maga na solenoid coil hpe n-gun jaw ai majaw, valve core gaw hkra maga de sit mat wa ai. Sau shang ai P gaw actuator a rodless chamber A hte matut nna, rod chamber B gaw sau bai nhtang wa ai port T hte matut nna, actuator hpe maga mi de shadut kau ai.
• Dingda maga na shara (coil B hpe n-gun jaw ai): Dingda maga na solenoid coil hpe n-gun jaw ai majaw, valve core gaw hkra maga de sit mat wa ai. Sau shang ai shara P gaw rodless chamber B hte matut nna, rodless chamber A gaw sau bai nhtang wa ai port T hte matut nna, actuator hpe n bung ai maga de shamu shamawt shangun ai.
Valve core hte valve hkum hkrang lapran na hkrak hkrak bung ai clearance hku nna ntsin lwi pru wa ai. Clearance size gaw hka lim ai lam hte n-gun yawm ai lam hpe hkrak hkra machyi shangun ai majaw, hka lim ai lam hte hka lim ai lam hpe hkrak hkra galaw na matu, grai kaja ai-htuk manu ai jak (grinding hte polishing zawn re ai) ni hpe galaw ra ai.
3. N-gun galai shai ai lam hte mahtai jaw ai atsam ningja ni
Solenoid valve a madung gaw wan n-gun hpe jak n-gun de galai shai ai lam rai nga ai: wan n-gun gaw wan n-gun coil hpe magnetic field byin shangun nna, dai gaw valve core a linear displacement de galai shai mat nna, hpang jahtum e hka n-gun (pressure and flow) a lam hpe galai shai kau ya ai. Shi a mahtai jaw ai lawan ai lam hpe wan n-gun coil a n-gun jat ai aten (ga shadawn milliseconds) hte valve core a jak rung n-gun n-gun n-gun a majaw shadawn sharam da ai. Hpa majaw nga yang, n-gun kaba ai bungli galaw ai masa hta, latency hpe shayawm kau lu na matu, coil hpe grau kaja hkra galaw ra ai (pulse{3}}width modulation (PWM) hpe hkang ai zawn re ai).
Madung shadut ai lam ni hte hpaji masa madung lam ni
Hydraulic solenoid valve ni a bungli galaw ai lam hpe lam amyu myu a majaw hkra machyi shangun ai:
• Electromagnetic n-gun n-gun: Coil kade lang kayin ai, ya aten na madang, core material (ga shadawn, silicon steel) a magnetic shang lu ai atsam ni gaw mawdaw gau lu ai atsam hpe hkrak sha hkra machyi shangun ai. Dai hta hkan nna, system a n-gun madang hpe madung tawn nna, htuk manu ai masat masa ni hpe lata ra ai.
• Sealing and wear: Valve core hte valve hkum hkrang lapran na sealing ntsa ni gaw, n-gun kaba ai-sau a n-gun hpe hkam sharang lu ra ai. Masha law malawng lang ai arung arai ni hta carbide hte stainless steel plating ni lawm nna, aten galu-bungli galaw ai shaloi hka pru wa na hpe shayawm lu na matu re.
• Grup yin hpe galai shai lu ai atsam: Katsi ai, katsi ai, n-gun rawng ai lam ni gaw solenoid coil a insulation galaw ai lam hpe hkra machyi shangun chye ai. Industrial-grade solenoid valve ni hpe gaw, nhprang wan hte hka n shang hkra galaw da ai nta ni (ga shadawn, IP65 makawp maga ai masat masa) hte galaw da ai.
Laika shawk shawn ai lam hte lata la ai lam a npawt tara ni
Hydraulic solenoid valve hpe lata ai shaloi, system a n-gun (ga shadawn 0-35 MPa), hka lwi ra ai lam (L/min kaw nna liter/min latsa daram du hkra), hkang zing ai ladat (manual/automatic/remote), hte media a arawn alai (sau san seng ai lam hte viscosi) ni hpe atsawm sha myit yu ra ai. Ga shadawn, gawgap jak ni hta hydraulic outrigger system ni gaw, lawan ai hku jat wa na matu hte nhtang wa na matu, masum- shara, mali-lam solenoid valve ni hpe lang chye ai; shing nrai, hkrak tup hkrak re ai jak rung ni hta hydraulic servo system ni gaw, matut manoi lwi ai hpe hkang lu na matu, hka lim ai lam n law ai, hka lim ai lam law ai solenoid proportional valve ni ra nga ai.
Daw dan lam
Hydraulic solenoid valve ni gaw, wan n-gun hte hka hpe hkang lu ai a synergistic effect hku nna, dai ni na hydraulic system ni hta n mai malap ai actuator langai byin wa sai. Shanhte a bungli galaw ai ladat ni gaw, wan n-gun, jak hpaji, hka htung hpaji ni hpe chye na ai lam ni hpe hpawng de da ai. Shanhte a ladat ni hpe sung sung chye na ai gaw, system design hpe grau kaja hkra galaw ya lu nna, jak rung ni hpe kam hpa mai ai lam hpe grau kaja hkra galaw ya lu ai. Material hpaji hte hkang zing ai hpaji masa ni rawt jat wa ai hte maren, hpaji rawng ai solenoid valve ni (sensor feedback hpe hpawng de da ai digital valve zawn re ai ni) gaw hydraulic system ni hpe grau hkrak ai hte grau hpaji rawng ai de woi sa wa nga ai.
