Pneumatic actuator -Pneumatik silinda
Ol kain 'Pneumatic Cylinder'
1.1 Stret Lain Klas
Ol standet niumatik silinda, ol liklik niumatik silinda, ol niumatik silinda i gat seip bilong pen-
Klamping Pneumatic cylinder: Wantaim lok, lok bilong katim win, na proteksen bilong pasim win
Pneumatic cylinder positioning: Pneumatic cylinder yet i no sapotim multi-point posisen o dabol strok
Dabol-eksis Niumatik silinda: Dabol autput fos, inap long sanap strong long sampela taim bilong benk.
Stretpela ples bilong 'Pneumatic cylinder' i dipen long mak bilong en. Taim yu yusim wantaim bikpela strong bilong autput o bikpela spit, yu mas putim wanpela mak. As bilong dispela em long stopim piston long kisim bikpela bagarap na bagarapim 'Pneumatic cylinder head'. Ol liklik piston, sotpela-strok 'Pneumatic cylinder', i save dipen long strongpela ain bilong ol yet
Gaid straksa: Singel-eksis Ol 'pneumatic cylinder' i no ken i gat lod stret na ol i mas gat ol straksa bilong gaid/lod-bearing (ol gaid 'shaft', 'linear bearing', 'linear guide'). Ol liklik piston, sotpela -strok 'Pneumatic cylinder', taim ol i no karim bikpela hevi, na ol i no gat ol 'guiding/load-bearing structures', ol tu i orait. Tripela-eksis Pneumatik silinda i gat ol pasin bilong wanpela 'guide rod'
Anti--self-rotation measures: Irregular cross-section, with guide rods
1.2 Rotary kain: Rotary Pneumatic cylinder
1.3 Ol wok kategori: Gripa Pneumatik silinda/pinga Pneumatik silinda, bloking Pneumatik silinda
2. Tiorikel autput fos bilong Pneumatik silinda
Theoretical thrust (N) bilong wanpela komon double-acting Pneumatic cylinder em: Fa=0.25π*D^2*P
Insait long fomula:
Pneumatic cylinder diameter (mm
Presa bilong wok (MPa) bilong 'Pneumatic cylinder'.
Theoretical tensile force (N) em: Fa=0.25π*(D-d)^2*P
Insait long fomula, taim d em i diamita bilong piston rod (mm), yumi ken ting olsem d=0.3D.
3. Lod reit bilong Pneumatik silinda
Lod reit bilong 'Pneumatic cylinder': Em i makim 'ratio' bilong 'actual load force' F bilong 'Pneumatic cylinder' i go long 'theoretical output force' F0.
Lod kapasiti em i wanpela bikpela samting long makim wanpela 'Pneumatic cylinder'. Strongpela 'load force' we i wok long 'piston shaft' i save senis wantaim ol narapela narapela lod kondisen.
Lod tru bilong Pneumatic silinda i save kamap long wok kondisen. Sapos ol i painimaut 'load rate' η, ol i ken painimaut tu 'theoretical output' bilong 'Pneumatic cylinder'. Seleksen bilong lod reit η i rileit long lod pefomens bilong Pneumatic silinda na muvmen spit bilong Pneumatic silinda.
4. Kalkulesen bilong autput 'thrust' na 'air consumption' bilong 'Pneumatic cylinder'
Kalkulesen bilong autput 'thrust' bilong 'Pneumatic cylinder'. Sapos yumi kisim wanpela '-rod double-acting Pneumatic cylinder olsem eksampel, strong F1 we piston rod i save kamapim taim piston i muv i go long rait sait na strong bilong pulim F2 we piston rod i save kamapim taim em i muv i go long lephan, yumi ken skelim bihainim ol ekwesen (10-2) na (10-3) :
(2) Ol i ken skelim 'air consumption q' bilong 'compressed air' long wanpela 'reciprocating stroke' bilong 'Pneumatic cylinder' long rot bilong 'equation' (10-4):
Long wanem, wok presa we wanwan 'pneumatic device' i nidim i narapela narapela, i mas i gat wanpela presa standet bilong skelim hamas win i yusim. Planti taim, ol i save senisim 'flow rate' bilong 'compressed air' long ol narapela narapela presa i go long 'free air flow rate' long 'standard atmospheric pressure' bilong skelim, em:
Q=q× (p+0.103) /0.103
Insait long fomula: Q - fri win konsumsen (m3/s), p - Woking presa bilong kompresen win (Mpa)
5. Pineumatik silinda seleksen
Folem wok na kondisen, makim stret wanem kain 'Pneumatic cylinder'.
Sapos i no gat wanpela 'impact phenomenon' o 'impact noise' taim 'Pneumatic cylinder' i kamap long pinis bilong 'stroke', orait ol i mas makim wanpela 'buffer Pneumatic cylinder'. Sapos yu nidim lait weit, yu mas makim wanpela lait-duty Pneumatic cylinder. Sapos spes bilong putim i sotpela na 'stroke' i sot, orait yu ken makim wanpela liklik 'Pneumatic cylinder'. I gat wanpela 'lateral load', na wanpela 'Pneumatic cylinder' wantaim wanpela 'guide rod' em i opsenel. Yu mas gat gutpela 'braking accuracy', na yu mas makim wanpela 'locking Pneumatic cylinder'. Piston rod i no ken tantanim. Yu ken makim wanpela 'Pneumatic cylinder' wantaim wanpela 'non-rotating rod function. Ol 'pneumatic cylinder' we i no inap long hat i mas stap long ol ples we i gat bikpela hat. Long ol ples we i save bagarap, ol i mas makim ol 'Pneumatic cylinder' we i no inap bagarap. Long ol ples we i gat planti das, ol i mas putim ol samting bilong karamapim das long arere bilong 'piston rod'. Taim ol i nidim polusen-fri, oil-fri o oil-fri lubriketed Pneumatic cylinders, etc. i mas makim. Ol i makim bikpela bilong 'Pneumatic cylinder' we ol i makim bihainim hevi bilong en, presa bilong win ol i yusim, na rot bilong wok
Yu mas makim 'Pneumatic cylinder stroke' na 'workpiece movement distance':
Em i rilet long taim bilong yusim na 'stroke' bilong 'mechanism', tasol planti taim, ol i no ken makim ful 'stroke' bilong pasim piston long bam wantaim 'Pneumatic cylinder head'. Sapos ol i yusim long pasim ol samting, na ol narapela samting, ol i mas putim moa 10 i go inap 20 mm bihainim mak bilong 'stroke'.
Yu mas makim 'Pneumatic cylinder series'
Makim kain instolesen bilong 'pneumatic cylinder'
Ol kain kain 'series' i gat kain kain rot bilong putim, olsem 'basic type', 'foot type', 'flange type', 'U-shaped hook', na 'shaft ear type'
Yu mas makim ol 'buffer': nogat 'buffer', 'rubber buffer', 'air buffer', na 'hydraulic shock absorber'
Ol i save yusim dispela magnetik induksen swit we ol i makim bilong painimaut ples bilong en, na ol i mas putim wanpela magnetik ring insait long Pneumatic cylinder
Ol hap bilong 'Pneumatic cylinder' we ol i makim i gat ol join we i stret long en
6. Ol 'brand' bilong ol 'Pneumatic cylinder' we planti man i save makim: Airtac na SMC
