DabolPneumatic CylinderSeleksen Gaid: Faivpela Ki Step long Tiori i go long Prektis
Seleksen bilong dabol-Pneumatic cylinder Pneumatic cylinder em i wanpela sistemik projek na em i no wanpela isipela samting bilong "makim Pneumatic silinda diamita bihainim strong bilong en". Sapos yu makim stret, dispela inap long mekim wok bilong ol ikwipmen i stap gut na stret longpela taim, tasol sapos yu no makim stret, dispela inap long mekim wok bilong en i no wok gut, bagarap long 'Pneumatic cylinder', o wok bilong en i no wok gut. Dispela atikol bai stiaim yu long wanpela klia "faiv-step rot" long makim wanpela dabol-pneumatik silinda long sait bilong saiens.
Step 1: Kalkuletim 'thrust' yu nidim na pastaim painimaut 'Pneumatic cylinder bore'
Dispela em i as bilong seleksen. Pastaim yu mas skelim 'theoretical thrust' we i mas i stap long draivim kago.
Kalkuletim 'theoretical thrust' (F):
F=(load mass m × acceleration a) + Frictional force f + external force F_external
(Lukim: Sapos muvmen i wankain o spit i liklik tru, yu ken lusim tingting long 'acceleration term'.)
Yu mas makim 'load rate' (η):
Standet kondisen (η Liklik o wankain olsem 50%):
Dispela em i situesen we ol i save yusim planti taim, na i save givim inap mak bilong laipspan na stebiliti bilong Pneumatic cylinder.
Liklik-spid o wankain muvmen (η Liklik o wankain olsem 70%): Sapos spit bilong silinda bilong 'Pneumatic' i isi tru (<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.
Kalkuletim 'theoretical output force' bilong 'Pneumatic cylinder' na 'reverse' kalkuletim 'Pneumatic cylinder bore':
Theoretical output force bilong double-Pneumatic cylinder f_Pneumatic cylinder=P ×A ×2 (we A em i 'cross-sectional area' bilong wanpela 'Pneumatic cylinder')
Fos bilong 'Pneumatic cylinder' we i mas kamap F_=F tiori / η
Olsem na, yumi ken kisim olsem A=F_ i nidim/(2 ×P), na bihain yumi ken skelim minimam 'Pneumatic cylinder diameter' D.
Olsem: Strust we ol i nidim em 300N, wok presa em 0.5MPa, na lod reit em 0.5.
F_ required=300N / 0.5=600N
A=600N/(2 ×5 bar ×10) ≈60 mm2 (Note: 1MPa=10bar≈10N/mm2)
Sapos D=2 ×sqrt(60/π) ≈8.74mm, orait yu mas makim wanpela 'Pneumatic cylinder' we i gat 'standard diameter' bilong 10mm.
Step 2: Sekim 'lateral load' na 'bending moment'
Dispela em i as bilong wok bilong makim ol 'double-Pneumatic cylinder Pneumatic cylinder, we i save mekim wok stret long 'guiding accuracy' na 'service life'. Maski 'double-pneumatic cylinder' inap long karim wanpela kain 'lateral load', em i no ken winim mak bilong en.
Rot: Folem 'Pneumatic cylinder bore' yu bin makim pastaim na 'stroke' tru, lukluk long "Maximum concentrated load" jat bilong dispela model bilong 'Pneumatic cylinder' (olsem yu lukim long namba wan piksa 5.4-26a).
Tru tru lateral lod we Pneumatic cylinder i save karim taim em i wok i mas liklik long mak we ol i ken kisim long 'stroke' olsem i stap long jat. Sapos ol i winim mak, ol i mas makim wanpela bikpela 'Pneumatic cylinder diameter' o wanpela strongpela 'guiding form' (olsem 'guide rod Pneumatic cylinder').
Step 3: Sekim 'kinetic energy' na makim kain 'buffer'
Piston bilong 'Pneumatic cylinder' i gat 'kinetic energy' long pinis bilong 'stroke' bilong en. Sapos 'kinetic energy' i bikpela tumas, em bai kamapim hevi, guria, na bagarap.
Kalkuletim 'kinetic energy' (E_k):
E_k = 1/2 ×m ×v²
(m i makim olgeta 'load mass', na v i makim mak bilong 'impact velocity')
Verifikasen: Skelim 'kinetic energy' we ol i bin kalkuletim wantaim 'allowable kinetic energy' veliu insait long 'Pneumatic cylinder sample' (olsem i stap long piksa 5.4-26b bilong namba wan teks).
Disisen
Sapos E_k < 'kinetic energy' we ol i ken larim long standet kain, orait makim 'basic type' wantaim 'cushion buffer' o 'adjustable gas buffer'.
Sapos E_k i bikpela, ol i mas makim wanpela model wantaim wanpela 'hydraulic buffer' (olsem CXSL series), long wanem, strong bilong en long kisim 'kinetic energy' em 2 o 3 taims bilong 'pneumatic buffer'.
Step 4: Tingim pasin bilong putim na bikpela hevi
Rot bilong putim (horizontal/vertikal) na 'overhang' (l) bilong lod bai kamapim sampela moa taim bilong kapsait, we bai mekim bikpela samting long sevis laip na seleksen bilong Pneumatic cylinder.
Olsem yumi lukim long piksa 5.4-27a, 'extended load m' bai kamapim wanpela 'moment' M=m ×g ×l longpela bilong l.
Rot: Em i gutpela long lukluk long 'dedicated selection diagram' we kampani i wokim (olsem i stap long piksa 5.4-27b bilong namba wan teks) bihainim 'installation form', 'stroke', 'speed', 'overhang l', na 'load mass' m.
Pinis bilong toktok: Dispela jat bai givim stret mak bilong 'Pneumatic cylinder bore' aninit long ol wok kondisen. Olsem, taim yu putim long horisontal, wantaim spit bilong 400mm/s, wanpela strok bilong 30mm, l=40mm, na m=0.2kg, jat i rekomendim long makim CXSW25 (Pneumatic cylinder bore 25mm) na noken makim wanpela liklik model.
Step 5: Konfemim ol series na ol narapela wok
Laspela, makim ol spesifik series na ol opsen bihainim ol risal we mipela i stori pinis long en:
CXS: Besik kain, kusen, o kusen bilong win.
CXSL: Em i gat wanpela 'hydraulic buffer', na em i gat strongpela strong long kisim 'kinetic energy' na em i gutpela long ol 'medium' na 'high-'spid aplikesen.
CXSW: Dabol stik kain, moa simetrik straksa, gutpela strong.
Narapela wok: Em i bikpela samting long gat wanpela magnetik ring (bilong putim ol magnetik swit bilong painimaut ples)? Em i gutpela long putim ol samting bilong helpim yu (olsem lek, 'flanges', na ol narapela samting)?

Dispela model em i wanpela gutpela risal bilong bihainim dispela seleksen proses antap:
Pneumatic cylinder diameter 32mm: Em i save givim inap 'thrust' na 'lateral load resistance', na inapim ol samting we planti 'medium-load' aplikesen i laikim.
CXSL series: I gat 'hydraulic buffer' insait long en, we inap long kisim gut ol hevi long pinis bilong 'stroke', na dispela i mekim wok i spit moa, wok gut, na i gat longpela sevis laip.
Stroke 75mm: Dispela i stap insait long 'stroke range' we ol i save yusim na em i gutpela long planti wok bilong holim na kisim.
Bikpela -stretpela stia: Dabol piston rod straksa i save givim gutpela 'bending moment resistance' taim yumi skelim wantaim ol nomol 'Pneumatic cylinder', na i mekim na i no gat rotesen long taim bilong wok na stretpela ples bilong en.
Tingting na liklik: Em i sevim spes bilong putim na em i gutpela tru long ol 'high-density layout insait long ol otomatik ikwipmen.
Pinis bilong tok: Sapos, bihain long kalkulesen long dispela faiv-step rot antap, yu painim olsem yu nidim wanpela liklik 'Pneumatic cylinder' we i gat diamita bilong 32mm, we i nidim gutpela 'buffering' na 'precision guidance', orait 12-CXSL32-75-Y69BZ em i wanpela gutpela samting we ol i bin sekim pinis.
