Kodi masilinda a pneumatic a single acting ndi chiyani?

Masilinda a pneumatic (opangidwa ndi pneumatic cylinder chubu, piston rod, cylinder cap), amatchedwanso masilinda a mpweya, ma pneumatic actuators, kapena pneumatic drives, ndi zida zosavuta zamakina zomwe zimagwiritsa ntchito mphamvu ya mpweya woponderezedwa ndikuwusandutsa mzere wozungulira.Kukonza kopepuka komanso kocheperako, masilinda a pneumatic amagwira ntchito mothamanga kwambiri komanso mocheperapo kuposa ma hydraulic kapena magetsi, koma ndi njira yoyera komanso yotsika mtengo yoyenda modalirika m'malo ambiri ogulitsa mafakitale.Chojambula chofala kwambiri chimakhala ndi silinda kapena chubu chomwe chimasindikizidwa pamapeto onse awiri, chokhala ndi kapu pamapeto amodzi ndi mutu pamapeto ena.Silinda ili ndi pisitoni, yomwe imamangiriridwa ndi ndodo.Ndodoyo imalowa ndi kutuluka kumapeto kwa chubu, moyendetsedwa ndi mpweya woponderezedwa.Pali mitundu iwiri ikuluikulu ya masitaelo: ochita kamodzi ndi awiri.

Mapangidwe a silinda ya pneumatic:
Mu masilinda a pneumatic a single-acting pneumatic, mpweya umaperekedwa kudzera padoko limodzi kupita mbali imodzi ya pistoni, zomwe zimapangitsa kuti ndodo ya pistoni ipitirire mbali imodzi kuti igwire ntchito monga kukweza chinthu.Mbali inayo imatulutsa mpweya ku chilengedwe.Kusuntha kolowera kosiyana kumachitika nthawi zambiri pogwiritsa ntchito kasupe wamakina, omwe amabwezeretsa ndodo ya pistoni pamalo ake oyamba kapena oyambira.Ma cylinders ena omwe amagwira ntchito imodzi amagwiritsa ntchito mphamvu yokoka, kulemera, kusuntha kwa makina, kapena kasupe wokwera kunja kuti agwiritse ntchito mphamvu yobwereranso, ngakhale kuti mapangidwewa sakhala ofala kwambiri.Mosiyana ndi izi, ma silinda a pneumatic ochita kawiri amakhala ndi madoko awiri omwe amapereka mpweya woponderezedwa kuti atalikitse ndikuchotsa ndodo ya pisitoni.Mapangidwe ochita kawiri amakhala ochulukirapo m'makampani onse, ndipo pafupifupi 95% ya ogwiritsa ntchito silinda iyi.Komabe, muzinthu zina, silinda imodzi yokha ndiyo njira yotsika mtengo komanso yoyenera.

Mu silinda imodzi yokha, mapangidwewo akhoza kukhala "malo oyambira" ndi kubwerera kwa masika, kapena "base position plus" ndi masika.Izi zimatengera ngati mpweya woponderezedwawo umagwiritsidwa ntchito kutulutsa sitiroko kapena in-stroke.Njira ina yoganizira za njira ziwirizi ndikukankhira ndi kukoka.Pakupanga kukankhira, kuthamanga kwa mpweya kumapanga kukankhira, komwe kumakankhira pisitoni.Ndi kamangidwe kakoko, kuthamanga kwa mpweya kumapanga kukankhira komwe kumakoka pisitoni.Mtundu wodziwika kwambiri ndi wowonjezera, womwe umagwiritsa ntchito kasupe wamkati kuti abwezeretse pisitoni pamalo ake pomwe mpweya watha.Ubwino umodzi wamapangidwe ochita kamodzi ndikuti ngati mphamvu ikatha kapena kutayika, pisitoni imabwereranso pamalo ake.Choyipa cha kalembedwe kameneka ndi kutulutsa mphamvu kosagwirizana panthawi ya sitiroko yonse chifukwa champhamvu yotsutsana ndi masika.Kutalika kwa sitiroko kumachepanso ndi malo omwe kasupe amafunikira, komanso kutalika kwa masika.

Komanso kumbukirani kuti ndi masilindala osagwira ntchito imodzi, ntchito ina imatayika chifukwa cha mphamvu yotsutsana ndi masika.Kuchepetsa mphamvuzi kuyenera kuganiziridwa poyesa mtundu wa silinda iyi.Diameter ndi sitiroko ndi zinthu zofunika kwambiri kuziganizira powerengera masaizi.Diameter imatanthawuza kukula kwa pistoni, komwe kumatanthawuza mphamvu yake yokhudzana ndi kuthamanga kwa mpweya.Ma diameter a silinda omwe alipo amatanthauzidwa ndi mtundu wa silinda ndi ISO kapena miyezo ina.Stroke imatanthawuza mamilimita angati omwe piston ndi piston rod zingayende.Lamulo lalikulu ndiloti kukula kwa silinda kumakhala, mphamvu zambiri zimatuluka.Kukula kwake kwa silinda kumayambira 8 mpaka 320 mm.

Kulingalira komaliza ndi kalembedwe kokwera.Kutengera wopanga, masinthidwe ambiri amapezeka.Zina mwazofala kwambiri ndi monga kukwera phazi, kukwera mchira, kumbuyo kwa pivot mount, ndi trunnion mount.Njira yabwino kwambiri idzatsimikiziridwa ndi ntchito yeniyeni ndi zigawo zina zamakina.
