Zaɓin nau'i biyu{0}Pneumatic Silinda Pneumatic Silinda shiri ne mai tsari kuma ko kaɗan ba abu mai sauƙi ba ne na "zaɓar diamita na Silinda Pneumatic bisa tursasawa". Zaɓin da ya dace zai iya tabbatar da tsayin lokaci mai tsayi da daidaitaccen aiki na kayan aiki, yayin da zaɓin da ba daidai ba zai iya haifar da asarar daidaito, lalata silinda mai ƙwanƙwasa, ko ma tsautsayi na samarwa. Wannan labarin zai jagorance ku ta hanyar bayyanannen "hanyar mataki guda biyar" don zaɓar nau'in silinda mai ciwon huhu a kimiyance.
Mataki na 1: Ƙirƙiri abin da ake buƙata kuma da farko ƙayyade ƙwayar Silinda Pneumatic
Wannan shine tushen zaɓi. Kuna buƙatar fara ƙididdige ƙa'idar da ake buƙata don fitar da kaya.
Yi ƙididdige ƙa'idar tuƙi (F):
F=(ɗaukarwa m × hanzari a) + Ƙarfin juzu'i f + ƙarfin waje F_external
(Lura: Idan motsi ya kasance iri ɗaya ko saurin ya yi ƙasa sosai, ana iya yin watsi da lokacin haɓakawa.)
Zaɓi ƙimar lodi (η):
Daidaitaccen yanayin (η Kasa da ko daidai da 50%):
Wannan shi ne yanayin da aka fi amfani da shi, yana samar da isasshen iyaka don tsawon rayuwa da kwanciyar hankali na Silinda Pneumatic.
Ƙarƙashin saurin gudu ko motsi iri ɗaya (η Kasa da ko dai-dai da 70%): Idan saurin silinda na huhu yana da sannu sosai (<100 mm/s) or it is static pressure maintenance, the load rate can be appropriately increased to select a smaller Pneumatic cylinder diameter, but caution should be exercised.
Yi ƙididdige ƙarfin fitarwa na ka'idar Pneumatic Silinda kuma baya lissafta ƙwanƙwasa Pneumatic Silinda:
Ƙarfin fitarwa na ƙa'idar sau biyu-Fushin silinda f_Pneumatic cylinder=P ×A ×2 (inda A shine giciye -bangaren yanki na silinda guda ɗaya)
Ƙarfin fitarwa na Silinda Pneumatic da ake buƙata F_ yana buƙatar=F Theory / η
Don haka, ana iya samun cewa ana buƙatar A=F_/(2 ×P), sannan za'a iya ƙididdige mafi ƙarancin diamita na Pneumatic Silinda D.
Misali: Tushen da ake buƙata shine 300N, matsa lamba na aiki shine 0.5MPa, kuma ana ɗaukar nauyin kaya azaman 0.5.
F_ da ake buƙata=300N / 0.5=600N
A=600N/(2 ×5 mashaya ×10) ≈60 mm² (Lura: 1MPa{6}}bar≈10N/mm²)
Idan D=2 ×sqrt(60/π) ≈8.74mm, to aƙalla za'a zaɓi silinda mai ƙwanƙwasa mai madaidaicin diamita na 10mm.

Mataki 3: Tabbatar da kuzarin motsa jiki kuma zaɓi nau'in buffer
Piston na Silinda Pneumatic yana da kuzarin motsa jiki a ƙarshen bugun jini. Idan makamashin motsi ya yi girma, zai haifar da tasiri, girgiza, da lalacewa.
Yi lissafin kuzarin motsa jiki (E_k):
E_k = 1/2 ×m ×v²
(m yana wakiltar jimlar nauyin nauyi, kuma v yana wakiltar matsakaicin saurin tasiri)
Tabbatarwa: Kwatanta kuzarin motsa jiki da aka ƙididdige tare da ƙimar "ƙarfin motsin motsi" a cikin samfurin Silinda Pneumatic (kamar yadda aka nuna a Hoto 5.4-26b na ainihin rubutu).
