Masiku ano, ma valve amagwiritsidwa ntchito kwambiri ndipneumatic actuators, ma actuators amagetsindi ma electro-hydraulic actuators.Malinga ndi mawonekedwe a ma actuators atatu, timasanthula momwe amagwiritsira ntchito ma valve:

Pneumatic System: Dongosolo la pneumatic limadalira Air compressor, yomwe imapanikiza mpweya, kuuyeretsa, kumapereka makina opangira pneumatic, ndikuyendetsa valavu.Mpweya umatulutsidwa molunjika kumlengalenga poyendetsa makinawo, ndipo njira ya gasi iyenera kuthana ndi gwero la gasi mosalekeza.Choncho, mpweya kompresa ambiri ayenera kugwiritsa ntchito imodzi, msewu waukulu ndi actuator pamaso nthambi ya mpweya akuchitira zigawo zikuluzikulu, monga chowumitsira, fyuluta decompression, mafuta nkhungu, etc. Amafunika kukonza nthawi zonse, m'malo.Pali njira zambiri zolumikizira mpweya, ndipo kuyang'anitsitsa nthawi zonse kumafunikanso kuti tipewe kutuluka kwa mpweya komanso kukhudza kuthamanga kwa dongosolo.Ntchito yovuta yotereyi ndikungowonetsetsa kuti makina oyendetsa pneumatic ayenera kusintha kuti achitepo kanthu.The pneumatic actuator ya valavu yayikulu, ndiko kuti, silinda, nthawi zambiri amasankhidwa molingana ndi kukakamizidwa kwa mpweya wina, koma chowongolera mpweya nthawi zambiri sichisuntha, kapena palibe chomwe chikuchitika, kapena kuchitapo kanthu kumachedwa komanso kuchitapo kanthu. si yosalala Izi nthawi zambiri zimachitika chifukwa cha izi:

Pamene njira ya mpweya imakhala ndi chinyezi, ngati kutentha kwa mpweya kuli pansi pa zero, madzi amaundana, kuzizira mpweya wa mpweya, kotero kuti mpweya wa mpweya sungathe kusuntha.

Njira ya gasiyo siitenthedwa ndi nkhungu yamafuta, kotero actuator imakhala yowuma kwa nthawi yayitali, zomwe zimapangitsa kuti kukangana kuchuluke kwambiri.The actuator yakakamira kapena ikulephera kusuntha.

Kuthamanga kwa mpweya wa compressor sikukwanira kapena pali kutuluka kwa mpweya, zomwe zimapangitsa kuti pneumatic actuator isapeze torque yokwanira yotsegula valavu mwamsanga kapena kutseka valavu kwathunthu.

Kusiyana kwa coefficient ya kukulitsa kwamafuta kwa gasi m'malo ozizira komanso otentha kumabweretsa kusiyana kwa nthawi yonse yoyenda ya pneumatic actuator.

Mpweyawu umakhala ndi mphamvu, zomwe zimapangitsa kuti pneumatic actuator ikhale yosalala, yolakwika mwadzidzidzi.

Ngati pempho lizimitsidwa mwachangu, chowongolera chibayo nthawi zambiri chimakhala ndi tanki yamafuta yokha, mu Fast shut-off, ngakhale gasi, mphamvu yoduliridwa, imatha kuonetsetsa kuti valavu itseke ndi kutseka, koma chifukwa chochepa. mphamvu, nthawi yotseka mofulumira sidzakhala yochepa kwambiri.

Hydraulic System: Hydraulic station system ndi makina ogwiritsira ntchito gasi ndi ofanana, amafunika kupanga mafuta othamanga kwambiri, amafunikira fyuluta yamafuta, amafunikira kuyala mafuta.Kusiyanitsa kulinso ubwino wa ma hydraulic system, hydraulic system ndikuyenda mkati, kuthamanga kwa mafuta nthawi zambiri kumakhala pafupifupi 40 ~ 120 kg, hydraulic actuator ndi yaying'ono kwambiri kuposa pneumatic actuator, ndipo mafuta a hydraulic alibe compressibility hydraulic silinda yomwe ikuyenda. bwino sizichitika kupanikizana jitter chodabwitsa.Dongosolo la hydraulic limatha kuthetsa kuperewera kwa ma pneumatic system.

Ubwino wa hydraulic system palokha ndikuwonetsetsa kuti valve yodalirika imagwira ntchito yabwino kwambiri, koma mafuta othamanga kwambiri, monga kusamalidwa kosayenera, kutulutsa mafuta nthawi zambiri kumachitika.Zigawo za hydraulic system monga ma servo valves, zosefera, mapaipi othamanga kwambiri, monga okwera mtengo, okwera mtengo.

Magetsi oyendetsa magetsi: magetsi oyendetsa magetsi ndi osiyana kwambiri ndi pneumatic actuator ndi hydraulic actuator, magetsi oyendetsa magetsi ndi omasuka ku ukapolo wa air compressor ndi hydraulic station, amangofunika kupeza magetsi ndi chizindikiro choyendetsa njira yodutsa.Poyerekeza ndi ma pneumatic system ndi hydraulic system, chowongolera chamagetsi chimakhala chophatikizika, chosavuta kukhazikitsa, ndipo ntchito yokonza imachepetsedwa kwambiri.
