Ol mak bilong silinda we i save stap sotpela taim, ol mak bilong spit bilong silinda
Ol pasin bilong silinda
Yumi ken kisim singel-rod dabol-ekting unbuffered silinda olsem wanpela eksampel long skelim mosen stet bilong silinda, olsem piksa i soim.
Solenoid valv i senisim rot, na win i pulap i go insait long 'rodless cavity' bilong silinda long rot bilong 'port A', na dispela i mekim presa P1 i go antap. Ges insait long 'rod cavity' i save go aut long 'exhaust port' bilong 'reverseng valve' long rot bilong 'port B', na presa P2 i save go daun. Taim presa i stap namel long sait we i no gat stik na sait we i gat 'robe' bilong piston i winim mak bilong presa bilong silinda, piston i stat long muv. Taim piston i stat, strong bilong 'friction' long piston na ol narapela hap i save pundaun wantu tasol long 'static friction' i go long 'dynamic friction', na dispela i mekim piston i seksek liklik. Bihain long piston i stat, 'rodless chamber' i stap long wanpela 'inflated state' wantaim bikpela volium, na 'rod-bearing chamber i stap long wanpela 'exhaust state' wantaim liklik volium. Wantaim ol samting olsem sais bilong ekstenel lod na 'impedance' bilong ol 'charging' na 'exhaust circuits', ol senis bilong presa P1 na P2 long tupela sait bilong piston tu i narapela narapela, na dispela i save kamapim ol narapela narapela senis bilong spit bilong muvmen bilong piston na strong bilong autput bilong silinda. Piksa i kam bihain em i wanpela piksa bilong 'transient characteristic curve' bilong silinda. Taim bilong givim pawa long solenoid valv i go inap long stat bilong muvmen bilong piston em i taim bilong dilei. Taim stat long taim solenoid valv i kisim pawa i go inap long taim piston i kamap long pinis bilong strok em i taim bilong kamap.
Olsem yumi ken lukim long piksa antap, long olgeta muvmen bilong piston, ol presa P1 na P2 insait long ol rum long tupela sait bilong piston na tu spit bilong muvmen U bilong piston i wok long senis. Dispela i kamap bikos maski 'rod cavity' i gat 'exhaust', volium bilong en i wok long go daun, olsem na 'downward trend' bilong p2 i go daun. Sapos 'exhaust' i no gutpela, p2 i ken go antap yet. Maski 'rodless cavity' i pulap, volium bilong en i wok long go antap. Sapos win saplai i no inap o piston i muv hariap tumas, p1 pes i ken pundaun. Bikos long senis bilong presa insait long ol rum long tupela sait bilong piston, dispela i save afektim gutpela autput fos na senis bilong muvmen spit bilong piston. Sapos 'external load force' na 'friction force' i no stap gut, ol senis long presa namel long tupela rum bilong silinda na muvmen spit bilong piston bai i hat moa.
Ol mak bilong spit bilong silinda
Spit bilong piston i save senis long olgeta muvmen bilong en. Maksimum veliu bilong spit ol i kolim maksimum spit na ol i makim olsem um. Long ol non-gas bafa silinda, maksimum spit i save stap long pinis bilong strok. Maksimum spit bilong ges bafa silinda i save stap long 'stroke position' pastaim long em i go insait long bafa.
Taim silinda i no gat ekstenel lod fos na ol i ting olsem 'exhaust' sait bilong silinda em i 'sound velocity exhaust' na presa bilong win i no liklik tumas, ol i kolim 'theoretical reference speed' bilong 'cylinder speed'.
u0=1920*S/A
Namel long ol, u0 em i 'theoretical reference speed'
S i makim kombinesen efektiv kros-seksen eria bilong eksos seket
A i makim 'effective cross-sectional area' bilong 'piston' long sait bilong 'exhaust'.
Tiorikel spit i klostu tru long maksimum spit bilong silinda taim i no gat lod, olsem na maksimum spit bilong silinda taim i no gat lod i wankain olsem u0. Taim hevi i go antap, mak bilong spit bilong silinda bai go daun.
Avereg spit v bilong wanpela silinda em i 'stroke' L bilong silinda na brukim long 'action time' t bilong silinda (planti taim ol i save skelim olsem taim bilong kamap). Spid bilong wanpela silinda we ol i save kolim em averes spit. Long ol raf kalkulesen, ol i save kisim mak bilong spit bilong silinda olsem 1.4 taims bilong averes spit.
Spid bilong wok bilong ol standet silinda em 50 i go inap 500mm/s. Taim spit i liklik long 50mm/s, bikos long 'frictional resistance' bilong silinda na 'compressibility' bilong ges, ol i no inap long mekim 'piston' i muv gut, na dispela bai kamap olsem 'intermittent movement' bai kamap, we ol i kolim "crawling". Taim spit i winim 500mm/s, 'frictional heat generation' bilong 'cylinder sealing ring' i save kamap strong moa, na dispela i save mekim ol 'sealing parts' i bagarap hariap, na dispela i save mekim win i lik, na i sotim sevis laip bilong en, na tu, dispela i save mekim 'impact force' i go antap long pinis bilong 'stroke', na dispela i save mekim 'mechanical life' i go antap. Long mekim silinda i wok long liklik spit, em i gutpela long yusim wanpela 'pneumatic-hydraulic damping cylinder o, long rot bilong wanpela 'pneumatic-hydraulic converter, yusim wanpela 'pneumatic-hydraulic combined cylinder long bosim liklik spit. Long wok long bikpela spit, em i gutpela long skruim longpela bilong silinda barel, mekim wok bilong silinda barel i kamap gutpela moa, strongim ol samting bilong pasim ring long daunim 'frictional resistance', na mekim gutpela wok bilong 'buffering', na ol narapela samting.
Antap em ol 'Transient characteristics' bilong silinda, ol 'velocity' mak bilong silinda, bilong kisim moa infomesen i stap longhttps://www.joosungauto.com/.
