Chinofambisa mhepo chinoshandisa kumanikidzwa kwemhepo kufambisa kuvhura, kuvhara kana kudzora vharuvhu. Chinonziwo chinodzora mhepo kana mudziyo wemhepo. Dzimwe nguva maactuator emhepo ane zvimwe zvishandiso zvinobatsira. Anowanzoshandiswa ndiwo mavharuvhu anoisa magetsi uye mashandiro evhiri reruoko. Basa rechinofambisa mhepo nderekushandisa musimboti wemhinduro kuti uvandudze mashandiro echinofambisa mhepo kuitira kuti chinofambisa mhepo chigone kuwana nzvimbo chaiyo zvichienderana nechiratidzo chekudzora chemutongi. Basa rechinofambisa mhepo chinoshandisa chinofambisa mhepo zvakananga kuti chichengetedze kugadzirwa kwakajairika kana sisitimu yekudzora ikakundikana nekuda kwekudzimwa kwemagetsi, kudzimwa kwegesi, kusabuda kwemutongi kana kukundikana kweactuator.
Nheyo yekushanda yePneumatic Actuator
Kana mweya wakamanikidzwa ukapinda mu actuator yemhepo kubva mu nozzle A, gasi rinosunda mapiston maviri kuti afambe akananga kumativi ese (cylinder head ends), uye rack iri papiston inosunda giya riri pa rotating shaft kuti ritenderere 90 degrees counterclockwise, uye vharuvhu rinovhurwa. Panguva ino, gasi riri kumativi ese e pneumatic actuator rinoburitswa kubva mu nozzle B. Kusiyana neizvi, kana mweya wakamanikidzwa uchipinda mu magumo maviri e pneumatic actuator kubva mu nozzle B, gasi rinosunda double piston kuti rifambe linearly pakati, uye rack iri papiston inosunda giya riri pa rotating shaft kuti ritenderere 90 degrees rightwise, uye vharuvhu rinovharwa. Panguva ino, gasi riri pakati pe pneumatic actuator rinoburitswa kubva mu nozzle A. Zviri pamusoro apa ndiyo nhungamiro ye transmission yemhando yakajairika. Zvichienderana nezvinodiwa nemushandisi, pneumatic actuator inogona kuiswa ne protocol ye transmission yakatarisana ne standard type, kureva kuti, axis yakasarudzwa inotenderera ne clockwise kuti ivhure vharuvhu, uye inotenderera ne counterclockwise kuti ivhare vharuvhu. Nozzle A ye single-acting (spring return type) pneumatic actuator ndiyo inlet yemhepo, uye nozzle B ndiyo gomba rekubuda naro (nozzle B inofanira kuiswa ne muffler). Nozzle A inovhura vharuvhu, uye simba remvura rinovhara vharuvhu kana mhepo yadzimwa.
Kushanda kwePneumatic Actuator
1. Simba rinobuda kana torque yemudziyo wepneumatic rinofanira kutevedzera mitemo yepasi rose neyevatengi
2. Kana pasina mutoro, sirinda inopinzwa nekumanikidzwa kwemhepo kwakataurwa mu "Tafura 2", uye kufamba kwayo kunofanira kunge kwakatsetseka pasina kuvharika kana kukambaira.
3. Pasi pekumanikidzwa kwemhepo kwe0.6MPa, simba rekubuda kana kupinza kwemudziyo wemhepo munzira dzese dzekuvhura nekuvhara harifanirwe kunge riri pasi pemutengo wakaratidzwa pazita remudziyo wemhepo, uye chiito chinofanira kunge chakachinjika, uye hapana kushanduka kusingaperi kana zvimwe zviitiko zvisina kujairika zvichaitika mune chero chikamu.
4. Kana bvunzo yekuvharira yaitwa nekushanda kwakanyanya, huwandu hwemhepo inobuda kubva kudivi rega rega rekumanikidzwa kwemusana hahufanirwe kudarika (3+0.15D)cm3/min (mamiriro akajairwa); huwandu hwemhepo inobuda kubva kumucheto wekuvhara uye mugodhi wekubuda haufanirwe kudarika (3+0.15d)cm3/min.
5. Kuedza simba kunoitwa nekumanikidzwa kwakanyanya kushanda ka1.5. Mushure mekuchengetedza kumanikidzwa kwekuedza kwemaminitsi matatu, chifukidziro chemagumo esirinda uye zvikamu zvechisimbiso zvisingachinji hazvibvumirwi kuva nekubuda kwemvura uye kushanduka kwechimiro.
6. Huwandu hwenguva yekushanda, mudziyo wepneumatic unotevedzera kushanda kwevharuvhu yepneumatic. Kana ichichengetedza torque yekubuda kana kugona kwekupinza munzira dzese dziri mbiri, huwandu hwemabasa ekuvhura nekuvhara hahufanirwe kunge huri pasi pe50,000 kanomwe (kutenderera kamwe chete kwekuvhura nekuvhara).
7. Pamidziyo yemhepo ine nzira dzekugadzirisa mafambiro emhepo, piston painofamba ichienda kunzvimbo yekupedzisira yekurohwa, haibvumirwi kurovera.
Mabhenefiti ePneumatic Actuators
1. Gamuchira zviratidzo zvegasi zvinoramba zviripo uye kuburitswa kwemagetsi zvakananga (mushure mekuwedzera mudziyo wekushandura magetsi/gasi, unogona zvakare kugamuchira zviratidzo zvemagetsi zvinoramba zviripo). Zvimwe zvinogona kuburitsa kuburitswa kwemakona mushure mekunge zvashongedzerwa neruoko rwerocker.
2. Kune mabasa ekuita akanaka neasina kunaka.
3. Kumhanya kwekufamba kwakanyanya, asi kumhanya kuchaderera kana mutoro wawedzera.
4. Simba rinobuda rine chekuita nekumanikidzwa kwekushanda.
5. Kuvimbika kwakanyanya, asi vharuvhu haigone kuchengetwa mushure mekunge mweya wakanganiswa (inogona kuchengetwa mushure mekuwedzera vharuvhu inochengetedza nzvimbo).
6. Hazvina kunaka kuita kuti zvirongwa zvienderane nezvikamu uye zvirongwa zvienderane.
7. Kugadzirisa kuri nyore uye kugona kuchinjika zvakanaka kunharaunda.
8. Simba guru rekuburitsa.
9. Ine basa rinodzivirira kuputika.

Zviyero zvekuiswa uye zvekubatanidza zvema actuator nemavharuvhu emhepo zvakagadzirwa zvichienderana nezvinodiwa pasi rose zve ISO5211, DIN3337 uye VDI/VDE3845, uye zvinogona kuchinjaniswa nema actuator emhepo akajairwa.
Buri rinobva mhepo rinoenderana neNAMUR standard.
Buri repasi remuchina wekufema (rinoenderana neISO5211 standard) rine mativi maviri, izvo zviri nyore kuisa mavharuvhu ane mativi mana kana kuti makona e45°.
