Ulwazi lwesicelo sokuphindaphinda amatywina entshukumo

Ukuphindaphinda amatywina entshukumo yenye yezona mfuno zokutywinwa eziqhelekileyo kujikelezo lwe-hydraulic kunye namalungu e-pneumatic kunye neenkqubo.Ukuphindaphinda amatywina okunyakaza asetyenziswa kwiipiston ze-cylinder zamandla kunye nemizimba ye-cylinder, iintloko ze-cylinder zokungenelela kwepiston kunye nazo zonke iintlobo zeevalve zesilayidi.I-gap yenziwe yintonga ye-cylindrical ene-cylindrical bore apho intonga ihamba nge-axially.Isenzo sokutywina sinciphisa ukuvuza kwe-axial yolwelo.Xa isetyenziswe njengetywina elijikelezayo elijikelezayo, i-O-ring inesiphumo esifanayo sokutywinwa kwangaphambili kunye nesiphumo sokuzitywina njengesitywina esisisigxina, kwaye inamandla okuhlawula ngokuzenzekelayo ukunxiba ngenxa ye-elasticity ye-O-ring.Nangona kunjalo, imeko inzima ngakumbi kunokutywinwa kwe-static ngenxa yesantya sokunyakaza kwentonga, uxinzelelo kunye ne-viscosity yolwelo xa utywinwa.

Xa ulwelo luphantsi koxinzelelo, iimolekyuli zolwelo zisebenzisana nomphezulu wesinyithi kwaye "iimolekyuli zepolar" eziqulethwe kulwelo zicwangciswe ngokusondeleyo kwaye zicwangciswe ngobunono kumphezulu wesinyithi, zenza umda oqinileyo wefilimu yeoyile ecaleni kwendawo yokutyibilika naphakathi amatywina, kunye nokuvelisa ukunamathela okukhulu kumphezulu wokutyibilika.Ifilimu ye-liquid isoloko ikhona phakathi kwesitywina kunye ne-reciprocating surface, iphinda isebenze njengesitywina kwaye ibaluleke kakhulu kwi-lubrication yendawo yokutywina ehambayo.

Nangona kunjalo, kuyingozi malunga nokuvuza.Nangona kunjalo, xa i-shaft ebuyiselayo ikhutshwe ngaphandle, ifilimu ye-liquid kwi-shaft ikhutshwe kunye ne-shaft kwaye, ngenxa yempembelelo "yokusula" yesitywina, xa i-shaft ebuyiselayo ibuyiselwa, ifilimu yamanzi igcinwa ngaphandle. into yokutywina.Njengoko inani lemivimbo ephindaphindayo lisanda, kokukhona ulwelo olungaphezulu lushiyeka ngaphandle, ekugqibeleni lwenze amathontsi e-oyile, okukuvuza kwetywina elibuyiselanayo.

Njengoko i-viscosity yeoli ye-hydraulic iyancipha ngokunyuka kweqondo lokushisa, ubukhulu befilimu buyancipha ngokufanelekileyo, ngoko ke xa izixhobo ze-hydraulic ziqaliswa kumaqondo aphantsi, ukuvuza kukhulu ekuqaleni kwentshukumo, kwaye njengoko ubushushu buphakama ngenxa yelahleko ezahlukeneyo. ngexesha lokuhamba, ukuvuza kudla ngokuhla ngokuthe ngcembe.

Ukubuyisela amatywina asetyenziswa kakhulu kwi.

1) kuxinzelelo oluphantsi lwezixhobo ze-hydraulic, ngokubanzi zikhawulelwe kwizibetho ezimfutshane kunye noxinzelelo oluphakathi olujikeleze i-10MPa.

2) Kwi-diameter encinci, i-stroke emfutshane kunye ne-medium pressure hydraulic slide valves.

3) Kwi-pneumatic slide valves kunye neesilinda ze-pneumatic.

4) Njenge-elastomer kwiitywina ezihambelanayo ezidibeneyo.
