I. Mitundu ya masilinda a pneumatic
Mu kufalikira kwa pneumatic, mphamvu yamphamvu ya gasi wothinikizidwa imasinthidwa kukhala mphamvu yamakina ndi ma pneumatic actuators. Ma cylinders a pneumatic akhoza kugawidwa m'magulu awiri: omwe amasuntha mobwerezabwereza ndi omwe amasuntha mobwerezabwereza. Masilinda a pneumatic omwe amasuntha mobwerezabwereza amathanso kugawidwa kukhala imodzi-yochita, yapawiri-yochita, yamtundu wa diaphragm, ndi masilinda apneumatic.
① Single-cylinder acting pneumatic: Mbali imodzi yokha imakhala ndi piston rod. Gasi amaperekedwa kuchokera mbali imodzi kuti iwunjike mphamvu, yomwe imakankhira piston kuti italikike ndi kubwereranso ndi kasupe kapena kulemera kwake-.
② Pawiri-silinda ya pneumatic: Gasi amaperekedwa mosinthana kuchokera mbali zonse ziwiri. Mphamvu imatuluka mbali imodzi kapena zonse ziwiri.
③ Diaphragm type pneumatic cylinder: Diaphragm imalowetsa pisitoni, ndipo mphamvu imatuluka mbali imodzi yokha. Amagwiritsa ntchito kasupe kuyikanso. Ili ndi ntchito yabwino yosindikiza koma sitiroko yayifupi.
④ Silinda ya pneumatic: Iyi ndi gawo latsopano. Imasintha mphamvu ya gasi wopanikizidwa kukhala mphamvu ya kinetic ya pisitoni{1}}yothamanga kwambiri (10-20 metres/sekondi) kuti igwire ntchito. Silinda ya pneumatic yamphamvu imakhala ndi chivundikiro chapakati chokhala ndi nozzle ndi doko lotulutsa. Chivundikiro chapakati ndi pisitoni zimagawaniza silinda ya pneumatic m'zipinda zitatu: chipinda chosungiramo mpweya, chipinda chamutu, ndi chipinda chamchira. Amagwiritsidwa ntchito kwambiri pazinthu zosiyanasiyana monga kudula, kukhomerera, kuphwanya, ndi kupanga. Masilinda a pneumatic omwe amayenda mobwerezabwereza kapena kusuntha mozungulira amatchedwa masilinda a pneumatic oscillating. Mabalawo amagawa chipinda chamkati kukhala pawiri, ndipo mpweya umaperekedwa mosinthana ku zipinda ziwirizo, zomwe zimapangitsa kuti shaft yotulutsa igwire ntchito yozungulira. Oscillation angle ndi zosakwana 280 digiri. Kuphatikiza apo, pali masilinda a rotary pneumatic, ma hydraulic damping pneumatic silinda, ndi masilinda apneumatic, ndi zina zambiri.
II. Ntchito ya silinda ya pneumatic: Imasintha mphamvu yamphamvu ya mpweya woponderezedwa kukhala mphamvu yamakina, kuyendetsa makinawo kuti azitha kuyenda mozungulira mozungulira, mozungulira komanso mozungulira.
III. Gulu la masilinda a pneumatic: ma silinda oyenda mozungulira obwerezabwereza, masilinda a pneumatic oyenda mozungulira, zikhadabo za pneumatic, ndi zina zambiri.
IV. Kapangidwe ka silinda ya pneumatic: Silinda ya pneumatic imapangidwa ndi mbiya ya silinda ya pneumatic, chivundikiro chomaliza, pisitoni, ndodo ya pisitoni ndi zida zosindikizira. Mapangidwe ake amkati akuwonetsedwa mu chithunzi chotsatirachi.
V. Mfundo Zachipangidwe za silinda ya pneumatic
1. Pneumatic cylinder mbiya: M'mimba mwake mkati mwa mbiya ya pneumatic silinda imatsimikizira mphamvu yotulutsa mpweya wa silinda. Pistoni iyenera kuyenda bwino mu mbiya ya silinda ya pneumatic. Pamwamba pa roughness wa mkati padziko ya pneumatic yamphamvu mbiya ayenera kufika Ra0.8um. Kwa migolo yachitsulo ya pneumatic cylinder, mkati mwake iyeneranso yokutidwa ndi chromium yolimba kuti muchepetse kusagwirizana ndi kutha, komanso kupewa dzimbiri. Zida za silinda ya pneumatic cylinder zitha kukhala zazitali{{6}zitsulo za kaboni,{7}}zowonjezera mphamvu za aluminiyamu, kapena mkuwa. Kwa masilinda ang'onoang'ono a pneumatic, machubu achitsulo chosapanga dzimbiri angagwiritsidwe ntchito. Masilinda a pneumatic okhala ndi ma switch maginito kapena omwe amagwiritsidwa ntchito m'malo owononga akuyenera kugwiritsa ntchito zinthu monga chitsulo chosapanga dzimbiri, aloyi ya aluminiyamu, kapena mkuwa. Ma pistoni a SMC CM2 pneumatic cylinder cylinder amagwiritsa ntchito mphete zomata zophatikizika kuti akwaniritse kusindikiza kwapawiri. Piston ndi piston rod zimalumikizidwa ndi kukanikiza{13}}zopanda mtedza.
2. Chivundikiro chomaliza: Chivundikiro chomaliza chili ndi madoko olowera ndi utsi, ndipo ena amakhalanso ndi makina otchinga mkati. Chovundikira kumapeto kwa ndodo chili ndi mphete zosindikizira ndi fumbi-mphete zotsimikizira kuti mpweya usatayike kuchokera ku ndodo ya pisitoni komanso kuti fumbi lakunja lisalowe mu silinda ya pneumatic. Chivundikiro chomaliza pa mbali ya ndodo chimakhala ndi manja owongolera kuti apititse patsogolo kulondola kwa silinda ya pneumatic, kupirira kachulukidwe kakang'ono kotsalira pa ndodo ya pisitoni, kuchepetsa kupotoza pamene ndodo ya pisitoni ikukulirakulira, ndikukulitsa moyo wautumiki wa silinda ya pneumatic. Kalondolondo wa kalozera nthawi zambiri amagwiritsa ntchito mafuta a sintered-okhala ndi ma aloyi kapena zopangira zamkuwa. Chivundikirocho chinali chopangidwa ndi chitsulo chonyezimira, koma tsopano pofuna kuchepetsa kulemera ndi kupewa dzimbiri, nthawi zambiri chimapangidwa ndi aluminum alloy by die{7}}casting. Masilinda ang'onoang'ono a pneumatic amagwiritsa ntchito zinthu zamkuwa.
3. Pistoni: Pistoni ndi mphamvu-yolandira mbali ya silinda ya mpweya. Pofuna kuteteza zipinda ziwiri za pisitoni kuti zisalankhulane wina ndi mzake, mphete yosindikizira ya pisitoni imaperekedwa. Zovala-zosamva mphete za pistoni zimatha kupititsa patsogolo kagwiridwe kake ka silinda ya pneumatic, kuchepetsa kuvala kwa mphete yosindikizira ya pisitoni, komanso kuchepetsa kukana kukangana. Zovala-zosamva mphete nthawi zambiri zimakhala zopangidwa ndi zinthu monga polyurethane, polytetrafluoroethylene, kapena nsalu-zopangidwa ndi reinforced synthetic resin. M'lifupi pisitoni zimatsimikiziridwa ndi kukula kwa mphete yosindikizira ndi kofunika kutsetsereka mbali kutalika. Ngati gawo lotsetsereka ndi lalifupi kwambiri, limakonda kuvala koyambirira komanso kujowina. Zida za pisitoni nthawi zambiri zimakhala aluminiyamu aloyi kapena chitsulo choponyedwa. Ma pistoni a masilinda ang'onoang'ono a pneumatic amapangidwa ndi mkuwa.
4. Piston rod: Piston rod ndiye katundu wofunika kwambiri-yokhala ndi mbali ya silinda ya pneumatic. Nthawi zambiri amapangidwa ndi-zitsulo za kaboni, ndipo amapangidwa ndi chitsulo cholimba cha chromium kapena chitsulo chosapanga dzimbiri kuti chiteteze ku dzimbiri komanso kuti mphete yosindikizira ya pisitoni isawonongeke.
5. Mphete yosindikiza: Zigawo zomwe zimasinthasintha kapena mobwerezabwereza zimatchedwa zisindikizo zosuntha, pamene kusindikiza kwa ziwalo zoyima kumatchedwa static seals. Njira zolumikizirana pakati pa mbiya ya silinda ya pneumatic ndi chivundikiro chomaliza zimaphatikizanso mitundu iyi: mtundu wophatikizika, mtundu wa riveting, mtundu wolumikizana ndi ulusi, mtundu wa flange, ndi mtundu wa ndodo.
6. Pamene silinda ya pneumatic ikugwira ntchito, imadalira nkhungu yamafuta mu mpweya woponderezedwa kuti idzoze pisitoni. Palinso ma silinda ochepera-omwe si opaka mpweya.
VI. Mfundo Yogwira Ntchito ya Pneumatic Cylinder
Kukankha ndi kukoka mphamvu pandodo ya pisitoni kumatsimikiziridwa kutengera mphamvu yofunikira kuti igwire ntchito. Posankha silinda ya pneumatic, ndikofunikira kuwonetsetsa kuti mphamvu yotulutsa ya silinda ya pneumatic ili ndi malire pang'ono. Ngati silinda ya pneumatic ndi yaying'ono kwambiri, mphamvu yotulutsa idzakhala yosakwanira, ndipo silinda ya pneumatic sigwira ntchito bwino; komabe, ngati silinda ya pneumatic silinda yaikulu kwambiri, sichidzangopangitsa kuti zipangizozo zikhale zolemera komanso zokwera mtengo, komanso zimawonjezera kugwiritsira ntchito mpweya, zomwe zimapangitsa kuti mphamvu ziwonongeke. Popanga zida, ndikofunikira kugwiritsa ntchito njira zokulitsa mphamvu momwe mungathere kuti muchepetse kukula kwa silinda ya pneumatic.
Pamwambapa pali mfundo zamapangidwe ndi ntchito zoyambira za silinda ya pneumatic. Kuti mudziwe zambiri zokhudzana ndi izi, pitanihttps://www.joosungauto.com/.
