VibiriSilinda wa mphepoBuku la Kusankha: Nthowa Zisanu Zakuzirwa Kufuma pa Fundo Kufikira pa Kuchita
Kusankha kwa silinda ya Pneumatic kaŵiri - Silinda ya Pneumatic ni ntchito yakunozgeka ndipo ni nkhani yipusu yayi ya "kusankha silinda la Pneumatic diameter mwakuyana na kukankhira". Kusankha makora kungapangiska kuti chipangizo chiŵe chakukhora ndiposo chakwenelera kwa nyengo yitali, apo kusankha kwambura kwenelera kungapangiska kuti chileke kugwira ntchito makora, kunanga silinda la Pneumatic, panji kupanga vinthu vileke kwenda makora. Nkhani iyi yizamumulongozgani mu nthowa yakumanyikwa makora ya "nthowa zinkhondi-" kuti musankhe mwasayansi silinda ya pneumatic yaŵiri-.
Nthowa yakwamba: Pendani nkhongono iyo yikukhumbikwa ndipo pakwamba manyani bore la silinda la Pneumatic
Ichi ndicho chikupangiska kuti ŵasankhepo. Mukwenera dankha kupenda nkhongono ya theoretical iyo yikukhumbikwa kuti muyendeske katundu.
Muŵerengerenge nkhongono ya theoretical (F):
F=(katundu unandi m × kufulumira a) + Nkhongono ya kukhweŵa f + nkhongono yakunja F_kunja
(Ziŵani kuti: Usange kwenda kwake kukuyana waka panji liwiro likuchepa chomene, lizgu lakuti kuchimbira lingalekeka.)
Sankhani mlingo wa katundu (η):
Mukhaliro wakumanyikwa (η Pachoko panji wakuyana na 50%):
Iyi ndiyo nyengo iyo yikugwiriskirika ncito comene, kupereka mphaka yakukwana ya umoyo na kukhazikika kwa silinda la Pneumatic.
Kuchepa-liwiro panji kwenda kwakuyana waka (η Kuchepera panji kuyana na 70%): Usange liwiro la silinda la Pneumatic likuchedwa chomene (<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.
Muŵerengerenge nkhongono yakufumira mu silinda ya Pneumatic na kuwerezgawerezga kuwerezgawerezga bore la silinda la Pneumatic:
Nkhongono yakufumiramo ya theoretical ya silinda ya Pneumatic yaŵiri - f_Silinda ya Pneumatic=P × A ×2 (apo A ni mtanda-malo ghakugaŵika gha silinda ya Pneumatic yimoza)
Nkhongono yakufumira mu silinda ya Pneumatic iyo yikukhumbikwa F_ yikukhumbikwa=F theory / η
Ntheura, tingasanga kuti A=F_ yikukhumbikwa/(2 × P), ndipo pamanyuma pake msinkhu wa silinda la Pneumatic D ungaŵerengeka.
Mwachiyelezgero: Nkhongono yakukhumbikwa ni 300N, nkhongono yakugwira ntchito ni 0.5MPa, ndipo katundu wakutoleka nga ni 0.5.
F_ wakukhumbikwa=300N / 0.5=600N
N / (2 × 5 mzere × 10) ≈60 mm2 (Ziŵani kuti: 1MPa=10 mzere ≈10N / mm2)
Usange D=2 ×sqrt(60/π) ≈8.74mm, mbwenu pafupifupi silinda la Pneumatic ilo lili na msinkhu wakukwana wa 10mm likwenera kusankhika.
Khwerero 2: Wonani katundu wa pambali na nyengo yakukhota
Ichi ndicho chinthu chikuru chomene pakusankha silinda la mphepo la silinda la mphepo, ilo likukhwaska mwachindunji kulongozga kwakukwana na umoyo wa uteŵeti. Nangauli silinda ya pneumatic yaŵiri-yingazizipizga katundu munyake wa pambali, kweni yikwenera yayi kuluska mtengo wake wakuzomerezgeka.
Nthowa: Kulingana na bore la silinda la Pneumatic ilo mukasankha pakwamba na stroke yeneco, wonani tchati cha "Katundu wakuŵikika chomene" cha chiyelezgero ichi cha silinda la Pneumatic (nga umo vikulongosorekera mu chithuzithuzi chakwamba 5.4-26a).
Katundu weneco wa pambali uyo silinda ya Pneumatic yikunyamura pa nyengo yakugwira nchito wakwenera kuŵa wakucepa kuluska mtengo wakuzomerezgeka wa stroke yakuyana nga umo vikulongosorekera pa chithuzithuzi. Usange mphaka yajumphapo, silinda yikuru ya Pneumatic panji mtundu wakulongozga wankhongono (nga ni ndodo yakulongozgera silinda ya Pneumatic) yikwenera kusankhika.
Khwerero 3: Woneseskani nkhongono ya kinetic na kusankha mtundu wa buffer .
Piston ya silinda ya Pneumatic ili na nkhongono ya kugwedezga pa umaliro wa stroke yake. Usange nkhongono ya kinetic njikuru chomene, yizamukhwaska, kugwedezeka, na kunanga.
Kuŵerengera nkhongono ya kinetic (E_k):
E_k = 1/2 ×m ×v²
(m yikwimira unandi wa katundu wose, ndipo v yikwimira liwiro likuru la kukhwaskika)
Kukhozgera: Yezgelerani nkhongono ya kinetic iyo yikuŵerengeka na mtengo wa "nkhongono ya kinetic yakuzomerezgeka" mu chiyelezgero cha silinda ya Pneumatic (nga umo vikulongosorekera mu Chithunzi 5.4-26b cha lemba lakwamba).
Chiganizo
Usange E_k < nkhongono yakuzomerezgeka ya mtundu wakumanyikwa, Sankhani mtundu wakwamba uwo uli na buffer ya khushoni panji buffer ya gasi yakusintha.
Usange E_k njikuru, chiyelezgero icho chili na chitetezo cha hayidiroliki (nga ni mndandanda wa CXSL) chikwenera kusankhika, chifukwa nkhongono zake zakupokera nkhongono zakuchitiska kuti nkhongono zake ziŵe zakukwana 2 panji 3 za chitetezo cha pneumatic.
Khwerero 4: Ghanaghanirani umo mwaŵikira na katundu wakusazgikira .
Nthowa yakuŵikamo (yakukhozgeka / yakuyimilira) na kukwera (l) kwa katundu kuzamupanga nyengo zakusazgikira zakugubuduka, izo zikukhwaska chomene umoyo wa uteŵeti na kusankha kwa silinda la Pneumatic.
Nga umo vikulongosoreka mu chithuzithuzi 5.4-27a, katundu wakusazgikira m wazamupanga nyengo yichoko waka M=m ×g ×l pamoza na utali wa l.
Nthowa: Nchakukhumbikwa kuwona chithuzithuzi cha kusankha chakujipeleka icho chili kupelekeka na wakupanga (nga umo vikulongosorekera mu chithuzithuzi 5.4-27b cha lemba lakwamba) mwakuyana na mawonekero ghakuŵikamo, stroke, liwiro, overhang l, na katundu m.
Kumalizga: Tchati ichi chizamupeleka mwaluŵiro mtengo wakukhumbikwa wa Pneumatic cylinder bore mu nyengo zakupambanapambana zakugwira ntchito. Mwachiyelezgero, para mwaŵika mwakudumura, na liwiro la 400mm / s, stroke ya 30mm, l =40mm, na m=0.2kg, chati yikuyowoya kuti musankhe CXSW25 (Pneumatic silinda bore 25mm) m'malo mwa chiyelezgero chichokovichoko.
Nthowa 5: Simikizgani mndandanda na milimo yinyake yakusazgikira
Paumaliro, sankhani mndandanda wakupambanapambana na ivyo mungasankha kuyana na ivyo vyasangika:
CXS: Mtundu wakwamba, khushoni, panji khushoni ya mphepo.
CXSL: Iwo uli na buffer ya hydraulic, uli na nkhongono zakukhora zakupokera nkhongono zakuchimbira ndipo ngwakwenelera kugwiliskira ntchito pa liwiro la pakatikati na lapachanya-.
CXSW: Mtundu wa ndodo kaŵiri, kapangidwe kakuyana chomene, kukhora makora.
Ntchito yakusazgikira: Kasi nchakukhumbikwa kuŵa na mphete ya maginito (yakuŵikamo masiwichi gha maginito kuti ŵamanye malo)? Kasi nchakukhumbikwa kuŵika vipangizo (nga ni malundi, flanges, na vinyake)?

Silinda la mphepo kaŵiri 12-CXSL32-75-Y69BZ
Chiyelezgero ichi ntchakufumapo cha kulondezga ndondomeko yakusankhira iyo yili pachanya apa:
Pneumatic cylinder diameter 32mm: Iwo ukupereka nkhongono yakukwana na kukana katundu wa pambali, kukwaniska ivyo vikukhumbikwa pa mapulogalamu ghanandi ghapakati -katundu.
CXSL series: Kuzengeka-mu hydraulic buffer, iyo yingatora makora nkhongono pa umaliro wa stroke, kuzomerezga kuti yigwirenge ntchito mwaluŵiro, yigwirenge ntchito makora, ndiposo yikhale nyengo yitali.
Stroke 75mm: Ici cikuwira mu mtundu wa stroke uwo ukugwiriskirika ncito comene ndipo ngwakwenelera ku nchito zinandi zakukhwaska na kusankha.
Ulongozgi wakukwana -: Kapangikiro ka ndodo ya piston kaŵiri kakupereka nkhongono zakukhota nyengo yakukhota pakuyaniska na masilinda gha Pneumatic ghambura kumanyikwa, kukhozgera kuti palije kuzungulira pa nyengo yakugwira ntchito na kuŵika malo ghakwenelera.
Kuwonda na kukhoma: Kusunga malo ghakuŵikamo ndipo nkhwakwenelera chomene ku mawonekero ghapachanya-mu vipangizo vyakujiyimira paŵekha.
Kumalizga: Usange, pamanyuma pa kupenda kwizira mu nthowa ya vigaŵa vinkhondi ivyo vili pacanya apa, mukusanga kuti mukukhumba silinda lakuwonda la Pneumatic ilo lili na msinkhu wa pafupifupi 32mm, ilo likukhumbikwira kuti liŵe na buffering yiwemi na ulongozgi wakukwana, mbwenu 12-CXSL32-75-Y69BZ yasankhika mwakukwana.
