RuaruaPorowhita PneumaticHe Aratohu Whiriwhiri: E rima nga waahanga matua mai i te Aria ki te Parakatihi
He kaupapa nahanaha te kowhiringa o -Pneumatic cylinder Pneumatic cylinders he kaupapa nahanaha, ehara hoki i te mea ngawari ki te "kowhiri i te diameter cylinder Pneumatic i runga i te pana". Ka taea e te kowhiringa tika te whakapumau i te wa roa me te tika o te mahi o nga taputapu, engari ma te he ko te kowhiringa ka ngaro te tika, te kino o te rango Pneumatic, tae atu ki te koretake o te whakaputa. Ma tenei tuhinga e arahi i a koe i roto i te "tikanga e rima-taahiraa" marama ki te whiriwhiri putaiao i tetahi-puera pneumatic rua.
Hipanga 1: Tātaihia te pana e hiahiatia ana, ka whakatau tuatahi i te kohao Pneumatic cylinder
Koinei te turanga mo te whiriwhiri. Me tatau tuatahi koe i te pana ariā e hiahiatia ana hei peia te uta.
Tātaihia te pana ariā (F):
F=(papatipu uta m × whakaterenga a) + Toi waku f + toana waho F_waho
(Tuhipoka: Mena he rite te motini, he iti rawa ranei te tere, ka kore e arohia te kupu whakatere.)
Tīpakohia te tere utanga (η):
Tikanga Paerewa (η Iti iho i te rite ranei ki te 50%):
Koinei te ahuatanga e whakamahia nuitia ana, e whakarato ana i te tawhē rawaka mo te roanga o te oranga me te pumau o te rango Pneumatic.
He iti-tere, he nekehanga rite ranei (η Iti iho i te rite ranei ki te 70%): Ki te tino puhoi te tere o te rango Pneumatic (<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.
Tātaihia te kaha whakaputa ariā o te rango Pneumatic me te whakamuri te tatau i te rango Pneumatic cylinder:
Ko te kaha whakaputa ariā o te rua-Pneumatic cylinder f_Pneumatic cylinder=P ×A ×2 (ko A ko te whiti-wahanga wahanga o te Pneumatic cylinder kotahi)
Ko te kaha whakaputa Pneumatic cylinder e hiahiatia ana F_ e hiahiatia ana=F ariā / η
No reira, ka taea te tiki A=F_ e hiahiatia ana/(2 ×P), katahi ka taea te tatau i te iti rawa o te porowhita Pneumatic diameter D.
Hei tauira: Ko te pana e hiahiatia ana ko te 300N, ko te pehanga mahi he 0.5MPa, ko te reiti kawenga ka tangohia hei 0.5.
F_ e hiahiatia ana=300N / 0.5=600N
He=600N/(2 ×5 pae ×10) ≈60 mm² (Tuhipoka: 1MPa=10pa≈10N/mm²)
Mēnā D=2 ×sqrt(60/π) ≈8.74mm, me kōwhiria he rango Pneumatic me te 10mm te diameter paerewa.
Hipanga 2: Tirohia te kawenga taha me te wa piko
Koinei te hononga matua i roto i te kowhiringa rua-Pneumatic cylinder Pneumatic cylinders, e pa ana ki te tika o te arahi me te oranga mahi. Ahakoa ka taea e te rango pneumati rua te tu ki tetahi kawenga taha, kaua e neke ake i tona uara e whakaaetia ana.
Tikanga: I runga i te putunga Pneumatic cylinder i tohua e koe i te tuatahi me te whiu tuturu, tirohia te "Maximum concentrated load" tūtohi o tenei tauira o Pneumatic cylinder (e whakaatu ana i te ahua tuatahi 5.4-26a).
Me iti iho i te uara e whakaaetia ana mo te whiu e rite ana ki te tutohi ko te kawenga taha taha tonu e mauhia ana e te rango Pneumatic i te wa e mahi ana. Mēnā ka hipa ake te rohe, me kōwhiria he rahi ake te diameter Pneumatic cylinder, he puka arataki kaha ake ranei (pēnei i te guide rod Pneumatic cylinder).
Hipanga 3: Manatokohia te kaha oro me te kowhiri i te momo parepare
Ko te piston o te Pneumatic cylinder he hiko hiko i te mutunga o tana whiu. Mēnā he nui rawa te pūngao oro, ka pā mai, he wiri, he kino.
Tātaihia te pūngao neke (E_k):
E_k = 1/2 ×m ×v²
(ko te m te tapeke o te papatipu kawenga, ko te v te tohu mo te tere o te paanga)
Manatokonga: Whakatauritehia te hiko hiko kua tatauhia me te uara "whakaaetia" i roto i te tauira Pneumatic cylinder (e whakaatuhia ana i te Whakaahua 5.4-26b o te tuhinga taketake).
Whakatau
Mēnā E_k < te pūngao neke e whakaaetia ana o te momo paerewa, Tīpakohia te momo taketake whai urunga pūreirei, pūrere hau taea te whakarite.
Mēnā he nui te E_k, me kōwhiria he tauira whai waipēhi (pērā i te raupapa CXSL), i te mea ko te kaha ki te tango i te kaha o te hiko he 2 ki te 3 nga wa o te paera pneumatic.
Hipanga 4: Whakaarohia te tuunga whakaurunga me te kawenga roa
Ko te tikanga whakaurunga (whakapae / poutū) me te whakairinga (l) o te kawenga ka whakaputa i etahi atu waa hurihuri, ka tino pa ki te oranga o te ratonga me te kowhiringa o te Pneumatic cylinder.
E whakaatu ana i te Whakaahua 5.4-27a, ko te kawenga toronga m ka puta he wa M=m ×g ×l i te roanga l.
Tikanga: Me titiro ki te hoahoa whiriwhiri i whakatapua e te kaiwhakanao (e whakaatu ana i te Whakaahua 5.4-27b o te tuhinga taketake) i runga i te ahua whakaurunga, te whiu, te tere, te whakairi l, me te papatipu uta m.
Te Whakamutunga: Ma tenei tūtohi e whakarato i te iti rawa o te putunga Pneumatic cylinder i raro i nga tikanga mahi. Hei tauira, ina whakaurua whakapae, me te tere o te 400mm/s, te whiu 30mm, l=40mm, me te m=0.2kg, ka tūtohu te tūtohi ki te whiriwhiri CXSW25 (Pneumatic cylinder bore 25mm) hei utu mo te tauira iti ake.
Hipanga 5: Whakaūhia te raupapa me etahi atu mahi
Ka mutu, tohua nga raupapa me nga whiringa i runga i nga hua kua whakahuahia ake nei:
CXS: Momo taketake, urunga, urunga hau ranei.
CXSL: He mea whakakikoruatia ki te waipēhi waipēhi, he kaha kaha ki te tango i te pūngao neke, he pai hoki mo nga tono reo me te teitei -tere.
CXSW: Momo tokotoko rua, hanga hangarite ake, pai ake te pakari.
He mahi taapiri: Me whai mowhiti autō (mo te whakauru i nga huringa autō mo te rapu waahi)? He mea tika ki te whakauru i nga taputapu (penei i nga waewae, nga flanges, me etahi atu)?

Puta Pneumatic rua 12-CXSL32-75-Y69BZ
Ko tenei tauira he hua angamaheni o te whai i te tukanga whiriwhiri i runga ake nei:
32mm te diameter o te rango pneumatic: Ka taea e ia te toka me te aatete kawenga taha taha, e tutuki ana i nga whakaritenga o te nuinga o nga tono uta -reo.
Raupapa CXSL: He mea hanga-i roto i te waipēhi waipēhi, ka kaha ki te tango i te paopao i te mutunga o te whiu, ka nui ake te tere o te mahi, te ngawari o te mahi, me te roa o te mahi.
Te whiu 75mm: Ka taka tenei ki roto i te awhe whiu e whakamahia nuitia ana, he pai hoki mo te nuinga o nga mahi whakahaere me te kohi.
-Arahi tino tika: Ko te hanganga o te poro piston rua he pai ake te aukati i te wa piko ka whakaritea ki nga rango Pneumatic noa, kia kore he hurihanga i te wa e mahi ana me te tuunga tika.
He angiangi me te kiato: Tiaki mokowā whakaurunga he tino pai mo te-tahora kiato teitei i roto i nga taputapu aunoa.
Whakamutunga: Mena, i muri i te tataunga i runga i nga tikanga e rima -taahiraa i runga ake nei, ka kite koe kei te hiahia koe ki te puoto Pneumatic angiangi me te diameter o te 32mm, me te pai o te buffering me te -arahi tino tika, na ko te 12-CXSL32-75-Y69BZ te kore e kore he whiringa pono kua whakamanahia.
