Saray agmanbayag ya katangian na silindro
Nayarin alaen tayo so single-rod double-acting unbuffered cylinder bilang alimbawa pian naanalisa so motion state na cylinder, a singa nanengneng ed ontumbok ya pigura.
Say solenoid valve et mangibabaliw na direksion, tan say lapuan na dagem et napano ed rodless cavity na cylinder panamegley na port A, kanian ontagey so pressure P1. Say gas ed abot na baras et ipapaway ed exhaust port na reversing valve panamegley na port B, tan onleksab so pressure P2. No say pandumaan na presyon ed baetan na rodless side tan robed side na piston et onabot ed tagey na sankaabebaan ya operating pressure na cylinder, say piston et onggapon onkiwas. No onggapo lay piston, say puersa na pan-apag na piston tan arum niran parte et biglan onleksab manlapud static friction ya anggad dynamic friction, kanian medyo onyegyeg so piston. Kayari na igapo na piston, say rodless chamber et walad inflated state ya walay indaak na volume, bangta say rod-bearing chamber et walad exhaust state ya walay inmabeba ya volume. Lapud pandumaan na saray bengatla a singa say kabaleg na external load tan say impedance na charging tan exhaust circuits, nanduruma met so pandurumaan na saray pressure P1 tan P2 ed duaran dapag na piston, ya mangitonton ed nanduruman pattern na kapeles na galaw na piston tan say epektibon output force na cylinder. Say ontumbok ya pigura et sakey ya diagram na transient characteristic curve na cylinder. Say panaon manlapud pangiter na enerhiya ed solenoid valve anggad gapoan na galaw na piston et say panaon na delay. Say panaon manlapud no kapigan say solenoid valve et na-energize anggad no kapigan say piston et akasabi ed sampot na stroke et say oras na isabi.
Unong ed nanengneng ed pigura ed tagey, diad interon galaw na piston, saray pressure P1 tan P2 ed saray silir ed duaran dapag na piston ontan met ed kapeles na galaw U na piston et manguuman. Saya so lapud anggaman say rod cavity et walay tambutso to, say karakel to et onkakapuy, kanian say onlelereg ya p2 et onkakapuy. No aliwan makinis so tambutso, nayarin ontagey nin siansia so p2. Anggaman say anggapoy baras ya abot et onlelereg, ondarakel so karakel to. No kulang so suplay na dagem odino maples so igalaw na piston, nayarin onleksab so p1 page. Lapud manguuman so pandumaan na presyon ed saray silir ed duaran dapag na piston, naapektoan so epektibon puersa ya ompaway tan say pandurumaan na kapeles na galaw na piston. No say external load force tan friction force et ag-establi, mas komplikado so panguman na pressure ed baetan na duaran silir na silindro tan say kapeles na igalaw na piston.
Say kapeles na silindro
Say kapeles na piston et manduruma ed interon galaw to. Say sankatageyan a balor na kapeles et tatawagen ya sankatageyan a kapeles tan tatawagen ya um. Parad saray non-gas buffer cylinders, say sankapelesan ya kapeles et kaslakan ya diad sampot na stroke. Say sankapelesan ya kapeles na gas buffer cylinder et kaslakan ya walad stroke position antis ya onloob ed buffer.
No say silindro et anggapoy external load force to tan ipapasen ya say exhaust side na cylinder et sound velocity exhaust tan say air source pressure et aliwan abeba, say kalkuladon peles na silindro et tatawagen ya theoretical reference speed.
u0=1920*S/A
Diad saratan, say u0 et say teoretikal a reperensya na kapeles
Say S et mangirerepresenta ed nankakasakey ya epektibon cross-sectional area na exhaust circuit
Say A et mangirerepresenta ed epektibon cross-sectional area na piston diad exhaust side.
Say teoretikal a kapeles et asingger ed sankatageyan a kapeles na silindro no anggapoy karga, kanian say sankatageyan a kapeles na silindro no anggapoy karga et mipara ed u0. No ondarakel so karga, onkupas so sankapelesan ya kapeles na silindro.
Say average ya kapeles v na sakey a silindro et say stroke L na silindro ya inapag ed action time t na silindro (kaslakan ya kalkulaen bilang arrival time). Say kapeles na sakey a silindro et kaslakan ya tutukoyen et say average ya kapeles. Diad magaspang a kalkulasyon, say sankatageyan a kapeles na silindro et kaslakan ya 1.4 a danay ed average a kapeles.
Say kapeles na operasyon na saray estandarten silindro et maslak ya 50 anggad 500mm/s. No say kapeles to et abeba nen 50mm/s, lapud ondarakel so frictional resistance na silindro tan say compressibility na gas, ag naseguro so maabig ya galaw na piston, tan nagawa so phenomenon na intermittent movement, ya tatawagen ya "crawling". No say kapeles et onlampas ed 500mm/s, say frictional heat generation na cylinder sealing ring et onloor, ya mamapeles ed pakasulong na saray sealing parts, ya pansengegan na itatagey na dagem, manpaatiw na serbisyo, tan mamarakep met ed impact force diad sampot na stroke, ya mangaapekta ed mechanical life. Pian naseguro ya say silindro et mankikimey ed abeban kapeles, mas maabig no mangusar na pneumatic-hydraulic damping cylinder odino, diad panamegley na pneumatic-hydraulic converter, mangusar na pneumatic-hydraulic combined cylinder parad abeban-kontrol na kapeles. Pian makapan-operate ed mas atagey a kapeles, kaukolan ya pabalegen so karukey na cylinder barrel, paaligwasen so inkasusto na panagproseso na cylinder barrel, paaligwasen so materyal na sealing ring pian nabawasan so frictional resistance, tan paaligwasen so buffering performance, tan arum nira.
Diad tagey et saray Transient characteristics na cylinder, saray velocity characteristics na cylinder content, pian naamtaan so kaaruman ya impormasyon ya misiglaotan et naromog edhttps://www.joosungauto.com/.
