Valve ya pneumatic solenoid yikulaŵilira umo mphepo yikuchitira (panji mphepo zinyake) mu dongosolo la pneumatic. Iwo ukugwiriskira ncito solenoid ya magesi kuti yigwirenge nchito ya vavu. Pano pali kulongosora mwakudumura fundo yakugwira ntchito ya vavu ya pneumatic solenoid:
1. Vinthu vyakuzirwa:
- Sosoid: Chipangizo cha magesi icho chikusintha nkhongono za magesi kuŵa chinthu cha makina. Lili na coul ya waya (chikoko cha solenoid) na mtundu wa chisulo uwo ukusunkhunyika (plunger panji armature).
- Vinyama Vinyama: Muli madoko na vigaŵa vya mphepo iyo yikwenda. Kanandi vikuŵa na doko lakunjilirapo, malo ghakufumiramo panji kujumphirapo, na madoko ghakufumiskika.
- Prenger panji Kumasuka: Mtima wakusunthika mukati mwa coil ya solenoid iyo yikusuntha para coil yili na nkhongono, kujura panji kujara vigaŵa vya vavu.
2. Fundo Yakugwira Ntchito:
Para Solenoid yili na Nkhongono:
1. Signal ya magesi: Magesi ghakuŵikika pa coil ya solenoid, ndipo ghakupanga magesi gha maginito.
2. Magnetic Field: Munda wa maginito uwo ukupangika na coil ukukopa plunger panji armature, kuwukoka ku pakati pa coil.
3. Kusuntha kwa Plunger: Kuyenda kwa plunger kukusintha malo gha vavu. Kulingana na kapangilo ka vavu, gulu ili lingajulika panji kujara vigaŵa vinyake mukati mwa thupi la vavu.
4. Mpweya Kulaŵilira Kulaŵilira: Kusintha kwa malo gha plunger kukulongozga mphepo iyo yikwenda mu vavu. Mwaciyelezgero, mu vavu iyo yajalika, para munthu wakwenda mu vavu, wazamujura vavu, ndipo ivi vizamupangiska kuti mphepo yifume ku malo ghakunjilira kufuma ku malo ghakunjilirapo ku doko lakufumamo.
Para Solenoid walije Def- ...
1. Electrical Signal Off: Magetsi ghakuzimika, ndipo munda wa maginito ukugaŵikana.
2. Return Mechanic: Kuwelera kwa nyengo yakuwelera panji katundu wakupangika wa vinthu vya plunger kukankhira plunger ku malo ghake ghakwamba.
3. Valve Position Reset: Kuyenda kwa plunger kukujara panji kujura vigaŵa vya mphepo, kuweleska vavu ku mtundu wake wakukhazikika (kaŵirikaŵiri wakujalirika panji wakujulika mwachizoloŵezi).
4. Mpweya Flow Stopd panji wakulongozgekaso: Mu vavu yakujalirika, mphepo yikuyimika apo plunger yikuwelera kuti yijale msewu. Mu vavu iyo yikujulika mwakwenelera, mphepo yikuchimbira para msewu uwu wajara.
3. Mitundu ya Mavavu gha Masoka gha Pneumatic:
- 2-Wa Valve: Wali na madowoko ghaŵiri (inlet na malo ghakufumiramo) ndipo ghangazomerezga panji kukanizga mphepo iyo yikwenda.
- 3-Wa Valve: ili na madowoko ghatatu (inlet, outlet, na kufumiska) ndipo lingasintha kwenda pakati pa nthowa zakupambanapambana, kanandi likugwiriskirika nchito pakulongozga actuators.
- 4-Wa Valve: ili na madowoko ghanayi panji ghanandi ndipo kanandi likugwiriskirika nchito kuti lilongozgenge kaŵiri -act masilinda, kulongozga mphepo kuti yiyenderenge panji kubwezereska silinda.
- 5-Wa Valve: Kuyana waka na vavu ya 4-way kweni na madowoko ghanyake ghakulongozgera chomene.
4. Mapulogalamu:
- Kulaŵilira kwa Vinthu: Mavalvu gha pneumatic solenoid ghakugwiriskirika nchito pakulongozga ma pneumatic actumatics, nga ni masilinda na magalimoto.
- Nthowa zakuchitira vinthu vyakujikora: Kugwiliskira ntchito mwamahara mu mafakitare ghakujiyimira paŵekha kuti ghalongozge makina na ndondomeko.
- Kunozga Kwakukhwaskana na Mawa: Kugwiliskira ntchito kuti mulongozge mphepo yakufinyikizgika mu ndondomeko zakupambanapambana za pneumatic.
Chiyerezgera cha vithuzithuzi:
Pano pali damu lambura kusuzga ilo likulongosora ntchito yakwamba ya 2- nthowa iyo yikujalika na vavu ya pneumatic solenoid:
Mukudumura, vavu ya pneumatic solenoid yikugwira ntchito mwakugwiliskira nchito electromechanical solenoid kuti yisunthire plunger, iyo yikujura panji kujara mphepo ya vavu ya mphepo, kulaŵilira mphepo iyo yikwenda mu dongosolo la pneumatic. Fundo iyi yikuzomerezga kuti vipangizo vya matenda gha mu thupi vilongozgeke makora na ndondomeko zakuchitira vinthu mwaŵene.
