A mochini o kenyang moea ke sesebelisoa se sebelisang moea o hloekileng e le mohloli oa matla ho khanna valve ho bula le ho koala.Melemo ea li-actuator tsa pneumatic ke lebelo le bulehileng / le haufi, polokeho, bopaki ba ho phatloha le litšenyehelo tse tlase.Ha ho bapisoa le li-actuator tsa motlakase, li-actuator tsa pneumatic li hloka ho hlomelloa ka li-positioners ho fihlela mesebetsi ea taolo e hole.
Sehloohong sena, re tla u tsebisa litataiso tse 4 tsa ho khetha mochini o kenyang moea, ka tšepo ea ho u thusa ho khetha mochini o nepahetseng oa moea.

1. Ho potoloha

Li-actuator tsa pneumatic li arotsoe ka setorouku sa angular le stroke linear.
Kotara-turn pneumatic actuator e potoloha ka likhato tse 90 'me e ka sebelisoa ho laola ho bula le ho koala li-valve tsa bolo kapa li-valve tsa serurubele.
Linear stroke pneumatic actuator e ea holimo le tlase ka tsela e otlolohileng 'me e sebelisoa ho laola ho bula le ho koala li-valve tsa heke, li-valve tsa heke ea thipa le li-valve tsa globe.

2. Torque

Mefuta e fapaneng ea li-actuator tsa pneumatic li na le mefuta e fapaneng ea torque.Re hloka ho lekanya torque e hlokahalang ho latela boholo, khatello le thepa ea 'mele oa valve, e le ho qoba boemo ba hore valve e ke ke ea buloa kapa ea koaloa ka thata.
Torque ea mohlala oa AT e tloha ho 5Nm ho isa ho 4678Nm
Moetso oa AW o na le torque ea 185Nm ho isa 157300
Torque ea mofuta oa joko ea Scotch ke 500Nm ho isa ho 40000Nm

3. Mofuta o le mong kapa mofuta o etsang habeli

Mefuta eohle ea li-actuator tsa pneumatic li arotsoe ka mefuta e le 'ngoe le tse peli.
Li-actuator tsa mofuta o le mong li na le liliba tse ngata kahare.E butsoe nakong ea moea, actuator e tla iketsetsa bocha ha phepelo ea moea e emisitsoe.Monyetla oa li-actuator tse sebetsang ka bonngoe ke polokeho.
Li-actuator tse sebetsang habeli ha li na liliba tse kahare.Moea ho bula le moea ho koala.Melemo ea ho sebetsa habeli ke lebelo la ho fetoha ka potlako, torque e phahameng le litšenyehelo tse tlase.

4. Lisebelisoa tsa moea

Re ka fana ka lisebelisoa tsa mohloli oa moea tse kang positioner, limit switch, pneumatic reversing valve, FRL le turbine hore u khethe ho finyella litlhoko tsa hau tse fapaneng.
