Lub actuator thiab kev hloov kho mechanism ntawm pneumatic actuator yog ib qho kev sib koom ua ke, thiab cov actuators yog hom yeeb yaj kiab, hom piston, hom diav rawg, thiab khib thiab pinion hom. Lub piston-hom muaj ib tug ntev stroke thiab yog haum rau lub sij hawm yuav tsum tau loj thrust; thaum lub diaphragm hom muaj ib tug me me stroke thiab tsuas yog ncaj qha tsav lub valve qia. Lub fork-type pneumatic actuator muaj cov yam ntxwv ntawm lub zog loj, thiab qhov chaw me me thiab lub zog nkhaus yog ntau dua nyob rau hauv txoj kab nrog lub torque nkhaus ntawm lub valve, tab sis nws tsis zoo nkauj heev; nws yog feem ntau siv rau li qub nrog siab torque. Rack-and-pinion pneumatic actuator muaj qhov zoo ntawm cov qauv yooj yim, ruaj khov thiab txhim khu kev qha, thiab kev nyab xeeb thiab tawg-pov thawj. Nws yog dav siv nyob rau hauv fais fab nroj tsuag, tshuaj lom neeg kev lag luam, roj refining, thiab lwm yam ntau lawm txheej txheem nrog rau kev ruaj ntseg siab.
Thaum npauj npaim valve qhib tag nrho, nws muaj qhov tsis txaus txaus. Thaum qhib qhov nruab nrab ntawm 15 degree thiab 70 degree, rhiab txaus tswj tau ua tau, yog li daim ntawv thov ntawm npauj npaim li qub muaj ntau heev nyob rau hauv qhov kev hloov loj-inch. Txij li thaum lub zog ntawm npauj npaim valve phaj yog so, feem ntau npauj npaim li qub tuaj yeem siv rau kev tshaj tawm nrog cov khoom raug tshem tawm. Nyob ntawm lub zog ntawm lub foob, nws kuj tuaj yeem siv rau cov hmoov thiab granular media.
