Nthawi zambiri ndikofunikira kukonza zinthu zosiyanasiyana zothandizira pamene ma valve a pneumatic akugwiritsidwa ntchito kuti awonjezere magwiridwe antchito awo kapena magwiridwe antchito awo. Zosefera za mpweya, ma valve a solenoid obwerera m'mbuyo, ma switch oletsa, malo oimika magetsi, ndi zina zotero ndi zowonjezera za ma valve a pneumatic. Fyuluta ya mpweya,valavu yochepetsera kupanikizika, ndi lubricator ndi zigawo zitatu zokonzera magwero a mpweya zomwe zimasonkhanitsidwa ngati magawo atatu a pneumatic muukadaulo wa pneumatic. Zigawozi zimagwiritsidwa ntchito kuyeretsa ndikusefa gwero la mpweya lomwe limalowa mu chipangizo cha pneumatic ndikulichotsa ku gwero la mpweya loyesedwa ndi chipangizocho. Chosinthira mphamvu mu dera chimagwira ntchito mofanana ndi kuthamanga kwa mpweya.

Mitundu yosiyanasiyana ya pneumaticvalavuzomangira

Chowongolera chotsegulira ndi kutseka mavavu okhala ndi malo awiri chokhala ndi chowongolera mpweya chogwira ntchito kawiri. (double entender)

Pamene dera la mpweya la dera latsekedwa kapena lalephera,valavuimatsegulidwa kapena kutsekedwa yokha chifukwa cha actuator yobwerera kwa spring. (Yogwira ntchito mofanana)

Valavu imodzi ya solenoid: magetsi akagwiritsidwa ntchito, valavu imatsegulidwa kapena kutsekedwa; mphamvu ikachotsedwa, valavu imatsegulidwa kapena kutsekedwa (mtundu wosaphulika umapezeka).

Valavu ya solenoid iwiri yokhala ndi ntchito yokumbukira komanso kapangidwe kosaphulika komwe kamatsegula pamene coil imodzi yapatsidwa mphamvu ndikutseka pamene coil inayo yapatsidwa mphamvu.

Chipangizo chochepetsera kusintha kwa switch: lankhulani chizindikiro cha malo a switch patali (mitundu yolimbana ndi kuphulika ikupezekanso).

Choyimitsa magetsi: Chimasintha ndikuwongolera kayendedwe kapakati ka valavu (mtundu wosaphulika ulipo) mogwirizana ndi kukula kwa chizindikiro chamagetsi (muyezo wa 4-20mA).

Choyimitsa mpweya: sinthani ndikuwongolera kayendedwe kapakati ka valavu mogwirizana ndi kukula kwa chizindikiro cha mpweya (cholembedwa kuti 0.02-0.1MPa).
Chosinthira magetsi (chomwe sichingaphulike): Sinthani chizindikiro chamagetsi kukhala chizindikiro cha mpweya kuti mugwiritse ntchito ndi choyimitsa mpweya.

Kuti mpweya ukhazikike bwino, kuyeretsa, ndi kudzola mafuta mbali zoyenda, chithandizo cha mpweya chimaphatikizapo magawo atatu: valavu yochepetsera kuthamanga kwa mpweya, fyuluta, ndi chotsukira mafuta.

Njira yogwiritsira ntchito ndi manja: Muzochitika zachilendo, kulamulira kokha kumatha kuchotsedwa pamanja.

Kusankha zowonjezera za ma valve a pneumatic:

Ma valve a pneumatic ndi zida zovuta zowongolera zokha zopangidwa ndi ziwalo zosiyanasiyana za pneumatic. Ogwiritsa ntchito ayenera kusankha mosamala kutengera zomwe zimafunika powongolera.

1. Mtundu wochita zinthu ziwiri, mtundu wochita zinthu kamodzi, kufotokozera kwa chitsanzo, ndi nthawi yochitira zinthu za pneumatic actuators.

2. Valavu ya solenoid yolamulira imodzi, valavu ya solenoid yolamulira kawiri, voteji yogwirira ntchito, ndi mavavu a solenoid amtundu woteteza kuphulika akupezeka.

3. Kuyankha kwa chizindikiro kumaphatikizapo izi: switch yamakina, switch yoyandikira, chizindikiro cha mphamvu yotulutsa, voltage yogwiritsidwa ntchito, ndi mtundu wosaphulika.

4. Malo: imodzi yamagetsi, ziwiri zopumira mpweya, 8 current, 4 mpweya wothamanga, 5 chosinthira magetsi, ndi mitundu 6 yosaphulika.

5. Kuchiza mpweya pogwiritsa ntchito zinthu zitatu: mafuta awiri odzola ndi valavu yochepetsera kuthamanga kwa fyuluta.

6. Njira yogwiritsira ntchito pamanja.
