Pneumatic system-a solenoid valve thlan dan hriat hi non-standard design zir nan a pawimawh hle!
Chumisolenoid valve hmanga siam a nipneumatic system-ah chuan gas flow kalna tur, pressure leh flow rate control-na atana core component a ni. A thlan dan hian system performance leh rintlakna a nghawng nghal vek a ni. Non-standard design tan chuan solenoid valve thlan danah hian hnathawh dan, performance parameter, leh compatibility te ang chi dimension hrang hrang te chu uluk taka ngaihtuah a ngai a ni. A hnuaia tarlan te hi selection knowledge systematic summary a ni:
I. Solenoid Valve hrang hrangte Core Parameters leh Selection Basis te
1. Medium ziarang nei
Compressed air-ah hian oil, moisture, a nih loh leh particulate matter a awm em? Valve body material (aluminum alloy, stainless steel, engineering plastic ang chi) leh sealing material (NBR, FKM, PTFE) te hi inmil a ngai a ni.
Medium chu corrosive gas a nih chuan fluororubber sealing nei fully stainless steel valve body thlan tur a ni.
2. Hnathawh pressure range
Minimum starting pressure: Direct-acting valve te hian a tlangpuiin 0.15MPa aia Greater emaw, a tlukpui emaw an mamawh a, pilot-operated valve erawh chu 0.01MPa thleng a hniam thei thung.
Upper pressure resistance limit: Valve body pangngai hian pressure 1.0MPa a tuar thei. High-pressure scenario tan chuan specification 1.6MPa aia sang thlan tur a ni.

3. Flow mamawh (Cv value /Kv value) 1.1.
Cylinder speed atanga flow rate mamawh chu chhut la, Cv value inmil valve thlang rawh.
Q: Flow rate L/min, D: cylinder diameter cm, L: Stroke cm, P: Pressure MPa, t: hun s
Throttling effect awm loh nan valve port diameter chu cylinder interface size aia tam emaw, a tlukpui emaw a ni tur a ni.
4. Voltage leh Power hman dan
DC (DC24V) hi power consumption hniam-proof scenario leh explosion-proof scenario atan a tha hle. AC220V hi a man a tlawm a, mahse a lum lutuk duh hle.
Low-power coil (<=1.5W) hian heat generation a ti tlem thei a, a dam chhung pawh a ti rei thei bawk.
5. Mode of movement
Single electronic control (spring return): Power a chhiat chuan automatic in a reset a, himna-first scenario atan a tha.
Dual electronic control (magnetic latching): Dual signal control a mamawh a, position retention mamawhna hun atan a tha hle.

Ii. Structural Type hrang hrang thlan dan
Direct-acting principle hian electromagnetic force hmangin valve core chu direct-in a khalh a. A thatna: Zero-voltage start-up leh fast response ( 20ms aia tlem emaw a tlukpui emaw); A that lohna: Diameter te tak te (a tlangpuiin Φ6mm aia tlem emaw, a tlukpui emaw); Scenario hman tur: traffic tlem leh high-frequency action te.
Pilot-operated principle hian air pressure hmangin valve core khalh nan a pui thin. A thatna: Flow rate lian leh power hman tlem; A chhiatna chu pilot pressure tlem ber (>=0.15MPa) a ngai a ni. Scenario hman tur: Cylinder lian tak tak leh main control valve te.
Iii. Environment-a insiamrem theihna tur ruahmanna siam
1. Temperature awm zat
Standard valve: 5℃atanga 50℃High-temperature valve (SMCSY7000 series ang chi) te hian 80℃a thleng thei . Low-temperature valve hian sealing bik a mamawh a ni.
2. Hriselna grade
IP65 (dust and water resistant) hmun hnim hring zinga hman tur; Explosion-proof valve (ExdIICT6) hi kang thei leh puak thei hmunah hman a ni.
3. Vibration leh Shock
High-frequency vibration scenario atan chuan misoperation ven nan mechanical locking nei valve (FestoMS6LS ang chi) thlang rawh.

Iv. Non-standard Design atana ngaihtuah tur bik
1. Compact taka install a ni
Multi-way valve group (FestoCPV10 ang chi) hian hmun a humhim a, ISO5599/1 standard base plate te pawh a support bawk.
2. Signal hmanga inzawmna siam
High-speed response scenario atan chuan wiring tihtlem nan bus interface nei intelligent valve (PROFINET/EtherCAT) thlang rawh.
3. Energy-saving design
Pulse solenoid valve (intermittent power supply) hian energy hmanral 90% in a tihtlem thei a, battery-powered equipment atan pawh a tha hle.
V. Selection Process entirnan
1.Thil mamawh thlirletna: Cylinder diameter Φ50mm, stroke 200mm, action time 0.5s, hnathawhna pressure 0.6MPa.
2. Flow chhut dan
Q 5 ^ 2=0.47 * * 20 * (0.6 + 1.02) / 0.5 material 340 l/min
3. Valve specification thlang rawh: Pilot-operated 5-way valve, Cv value 1.2 aia tam emaw, a tlukpui (Φ12mm diameter nena inmil) thlang rawh, SMCVQZ series ang chi.
Vi. Hriatthiam lohna leh chinfel dan tlangpui
Zawhna 1: Valve body ah boruak a leak a
Countermeasures: Sealing ring a wear loh enfiah la, hard anodizing treatment (Burkert6014 ang chi) hmanga valve core thlan hmasak ber tur a ni.
Zawhna 2: Solenoid valve chu a lum lutuk a
Countermeasures: Power-power coil-ah switch emaw, heat sink dah emaw la, chu chuan power-a hun chhunga 90% aia tam a awm loh nan.
Above is Pneumatic system-a solenoid valve thlan dan hriat hi non-standard design zir nan hriatna pawimawh tak a ni! lungawi. A kaihhnawih thu belhchian dawl zawk hriat duh chuan tlawh theih a nihttps://www.joosungauto.com/ ah hian a awm bawk..
