Hydraulic Bellows
Hydraulic corrugated pipe em i wanpela 'flexible sealing pipe' we ol i ken skruim na bendim, planti taim ol i save wokim long planti kain kain metal pepa (o ol 'high-performance polymers') long rot bilong 'precision welding' o 'forming' proses, na kamapim wanpela 'corrugated shape'. Bikpela wok bilong en em long kamapim wanpela gutpela na 'leak free channel' namel long ol samting we i no senis na ol samting i muv long inapim ol kompleks muvmen.
Ol 'hydraulic bellows' i save kisim pawa long ol 'hydraulic cylinder' na ol i save bosim wara long rot bilong ol 'bellows' o 'sealing rings'. Olsem, long disain bilong ol valv, ol i save yusim ol paip we i gat 'corrugated' olsem ol 'sealing element' na ol i save yusim ol 'hydraulic cylinder' long mekim ol 'switching' eksen. Long mekanikel transmisin, ol haidrolik belo inap long senisim ol tradisenel mekanikel transmisin divais, daunim hevi bilong wok, na skruim sevis laip.

Ol bikpela teknikel paramita (ol bikpela indiketa bilong makim)
Taim yu makim ol 'hydraulic corrugated pipes', yu mas tingim gut ol dispela samting bilong mekim ol i ken wok gut wantaim 'hydraulic system':
Wok Presa:Em i makim mak bilong haidrolik presa we ol 'bellows' inap long karim taim ol i wok longpela taim. Em i mas 1.2 i go inap 1.5 taim moa long wok presa bilong sistem (sefti fakta) long stopim 'overpressure' i bruk.
Tempereja bilong wok:Ol i makim dispela samting bihainim namel tempereja na tempereja bilong ples. Ol metal belo i save karamapim tempereja bilong -200 digri i go inap 600 digri (inap long 1000 digri long ol hai-temperature aloi), tasol ol plastik belo i save karamapim tempereja bilong -40 digri i go inap 80 digri.
Pe bilong kompensesen bilong lusim ples:Em i gat 'axial compensation amount' (bikpela senis longpela bilong 'tension/compression'), 'lateral compensation amount' (maksimum distens bilong 'lateral offset'), na 'angular compensation amount' (maksimum 'deflection Angle'), we i mas bikpela moa long 'actual displacement amount' we sistem i kamapim.
Midia Kompatibiliti:Mekim gut olsem ol samting bilong 'corrugated pipe' i no ken kisim ol kemikel riaksen wantaim 'hydraulic medium' (olsem mineral oil, 'synthetic hydraulic oil', wara-ethylene glycol solution), na abrusim korosen o ol samting i kamap lapun (olsem, yu no inap yusim kabon stiel long wara-haidrolik fluid).
Nominal Diamita:Em i wankain olsem insait diamita bilong paiplain, planti taim em i save stat long DN6 i go inap long DN500 (ol i mas stretim long ol bikpela diamita), na em i save mekim ron na presa i lus.
Laip bilong les:Em i makim namba bilong ol 'reciprocating deformation cycles' we wanpela 'bellows' inap long karim aninit long presa na 'displacement' (planti taim ol i mas winim o wankain olsem 10,000 taim, na long ol indastriel ikwipmen, bikpela moa o wankain olsem 100,000 taim). Sapos laip i no inap, dispela bai mekim na bodi i bruk hariap.
