Dab tsi yog qhov zoo ntawm pneumatic actuators piv rau cov tshuab hluav taws xob
Pneumatic actuator hais txog tus actuator uas siv cua txias los tsav qhib thiab kaw lossis kho qhov qub. Nws kuj tseem hu ua pneumatic actuator lossis pneumatic device, tab sis nws feem ntau hu ua pneumatic taub hau. Tus actuator thiab kev hloov kho ntawm lub tshuab pneumatic yog kev sib koom ua ke, thiab tus actuator muaj hom membrane, hom piston, hom rab diav rawg thiab khib thiab hom pinion. Hom piston muaj mob stroke ntev, uas haum rau lub sijhawm uas xav tau kev nrawm ntau dua; thaum lub hom membrane muaj qhov mob me me thiab tsuas tuaj yeem ncaj qha tsav lub valve qia. Diav rawg-hom pneumatic actuator muaj cov yam ntxwv ntawm lub zog loj, qhov chaw me me, thiab lub zog nkhaus ntau dua nyob rau hauv kab nrog lub zog nkhaus ntawm lub valve. Txawm li cas los xij, vim nws tsis zoo nkauj heev, nws feem ntau siv rau ntawm qhov qub nrog lub zog loj. Thaum kawg, khib-thiab-pinion pneumatic actuator muaj cov yam ntxwv ntawm cov qauv yooj yim, ruaj khov thiab txhim khu kev qha, thiab kev nyab xeeb thiab tiv thaiv kev tawg. Nws tau siv dav hauv cov chaw tsim hluav taws xob, kev lag luam tshuaj lom neeg, kev kho roj thiab lwm yam txheej txheem tsim khoom uas xav tau kev nyab xeeb siab.
Coob leej neeg xav tsis thoob tias lub tshuab ua haujlwm pneumatic zoo dua lossis cov tshuab hluav taws xob. Qhov tseeb, hais txog kev ua haujlwm tau zoo, qhov zoo ntawm cov tshuab pneumatic piv rau cov tshuab hluav taws xob feem ntau suav nrog plaub yam hauv qab no:
(1) Lub nra hnyav thiab tuaj yeem hloov kho rau daim ntawv thov lub zog loj.
(2) Ua nrawm thiab teb sai.
(3) Kev hloov pauv chaw ua haujlwm tau zoo, tshwj xeeb tshaj yog nyob rau qhov chaw ua haujlwm hnyav xws li nplaim taws, tawg, plua plav, muaj zog hlau nplaum, hluav taws xob thiab kev co, nws zoo tshaj rau kev tswj hluav taws xob, hluav taws xob thiab hluav taws xob.
(4) Lub cev muaj zog tau yooj yim puas thaum mob stroke raug thaiv lossis lub valve qia raug khi.
