A pneumatic actuator ndi chipangizo chomwe chimagwiritsa ntchito mpweya woyera ngati gwero lamphamvu kuyendetsa valve kuti itsegule ndi kutseka.Ubwino wa ma actuators a pneumatic ndi liwiro lotseguka / kutsekeka, chitetezo, kusaphulika komanso mtengo wotsika.Poyerekeza ndi ma actuators amagetsi, ma pneumatic actuators amayenera kukhala ndi ma positioners kuti akwaniritse ntchito zowongolera kutali.
M'nkhaniyi, tikuwonetsani malangizo a 4 posankha makina opangira pneumatic, ndikuyembekeza kukuthandizani kusankha choyatsira pneumatic yoyenera.

1. Kuzungulira

Pneumatic actuators amagawidwa m'makona aang'ono ndi sitiroko yozungulira.
The quarter-turn pneumatic actuator imazungulira madigiri 90 ndipo imatha kugwiritsidwa ntchito kuwongolera kutsegula ndi kutseka kwa mavavu a mpira kapena ma valve agulugufe.
Linear stroke pneumatic actuator imayenda mmwamba ndi pansi molunjika ndipo imagwiritsidwa ntchito kuwongolera kutsegula ndi kutseka kwa mavavu a zipata, ma valve a zipata za mpeni ndi ma valve a globe.

2. Torque

Mitundu yosiyanasiyana ya ma actuators a pneumatic ili ndi ma torque osiyanasiyana.Tiyenera kuyerekezera torque yofunikira molingana ndi kukula, kupanikizika ndi zinthu za thupi la valve, kuti tipewe vuto lomwe valavu silingatsegulidwe kapena kutsekedwa mwamphamvu.
Ma torque amtundu wa AT amachokera ku 5Nm mpaka 4678Nm
Mtundu wa AW uli ndi torque ya 185Nm mpaka 157300
Makokedwe amtundu wa Scotch goli ndi 500Nm mpaka 40000Nm

3. Mtundu umodzi kapena wochita kawiri

Mitundu yonse ya makina opangira pneumatic amagawidwa m'magulu amodzi komanso awiri.
Ma actuators amtundu umodzi amakhala ndi akasupe angapo mkati.Tsegulani panthawi ya mpweya wabwino, actuator idzayambiranso pokhapokha mpweya ukayimitsidwa.Ubwino wa ma actuators ochita kamodzi ndi chitetezo.
Othandizira ochita kawiri alibe akasupe amkati.Mpweya wotsegula ndi mpweya kutseka.Ubwino wakuchita kawiri ndikuthamanga kwachangu, torque yayikulu komanso mtengo wotsika.

4. Chalk pneumatic

Titha kupereka zowonjezera zowonjezera mpweya monga poyikira, kusintha malire, valavu yobwezeretsa pneumatic, FRL ndi turbine kuti musankhe kukwaniritsa zosowa zanu zosiyanasiyana.
