A i-pneumatic actuator iyidivayisi esebenzisa umoya ohlanzekile njengomthombo wamandla wokushayela i-valve ukuze ivule futhi ivale.Izinzuzo zama-actuator womoya ukuvula/ukuvala ngokushesha isivinini, ukuphepha, ukuvikela ukuqhuma kanye nezindleko eziphansi.Uma kuqhathaniswa nama-actuator kagesi, ama-actuator e-pneumatic adinga ukuhlonyiswa ngezindawo ukuze afeze imisebenzi yesilawuli kude.
Kulesi sihloko, sizokwethula imihlahlandlela emi-4 yokukhetha i-actuator yomoya, ngethemba lokukusiza ukuthi ukhethe i-actuator yomoya efanele.

1. Ukuzungeza

Ama-actuator e-pneumatic ahlukaniswe abe yi-angular stroke kanye ne-linear stroke.
I-quarter-turn pneumatic actuator izungeziswe ngamadigri angu-90 futhi ingasetshenziswa ukulawula ukuvuleka nokuvalwa kwamavalvu ebhola noma amavalvu ovemvane.
I-linear stroke actumatic pneumatic actuator iya phezulu naphansi ngomugqa oqondile futhi isetshenziselwa ukulawula ukuvuleka nokuvalwa kwamavalvu esango, amavalvu esango lommese namavalvu eglobhu.

2. Torque

Izinhlobo ezihlukene zama-actuator we-pneumatic zinamabanga we-torque ahlukene.Sidinga ukulinganisa i-torque edingekayo ngokusho kobukhulu, ingcindezi kanye nezinto ezibonakalayo zomzimba we-valve, ukuze sigweme isimo sokuthi i-valve ayikwazi ukuvulwa noma ivalwe ngokuqinile.
I-torque yemodeli ye-AT isuka ku-5Nm iye ku-4678Nm
Imodeli ye-AW ine-torque engu-185Nm kuya ku-157300
I-torque yohlobo lwe-Scotch joke ingu-500Nm kuya ku-40000Nm

3. Uhlobo lwe-single-acting noma uhlobo olukabili

Wonke amamodeli wama-actuator we-pneumatic ahlukaniswe ngezinhlobo ezibambayo kanye nezisebenza kabili.
Ama-activator ohlobo olulodwa aneziphethu eziningi ngaphakathi.Vula ngesikhathi sokungenisa umoya, i-actuator izosetha kabusha ngokuzenzakalelayo lapho ukunikezwa komoya kumisiwe isikhashana.Inzuzo yama-activator asebenza kanye ukuphepha.
Ama-activator asebenza kabili awanazo iziphethu zangaphakathi.Umoya ukuze uvule futhi umoya uvale.Izinzuzo ze-double acting isivinini sokushintsha ngokushesha, i-torque ephezulu kanye nezindleko eziphansi.

4. Izesekeli zomoya

Singakunikeza izesekeli zomthombo womoya njenge-positioner, switch switch, i-valve ehlehlisa umoya womoya, i-FRL ne-turbine ukuze ukhethe ukuze uhlangabezane nezidingo zakho ezihlukene.
