Cov kauj ruam foob yog tsim los ntawm kauj ruam foob thiab O-ring.
Kev ua tau zoo thiab kev ntseeg siab ntawm cov tshuab hydraulic thiab cov twj tso kua mis yog nyob ntawm qhov ua tau zoo ntawm cov ntsaws ruaj ruaj, uas cov piston pas nrig foob thiab lub piston foob yog cov khoom siv sib khi yooj yim.Cov kauj ruam ua ke cov ntsaws ruaj ruaj (cov kauj ruam cov ntsaws ruaj ruaj ntxiv rau O-ring seals) yog ib qho ntawm feem ntau siv piston pas nrig ntsaws ruaj ruaj thiab kuj tseem siv hauv piston seals.
Hydraulic machinery ibd twj tso kua mis nyob rau hauv cov kauj ruam ua ke ntawm seals nws cov yam ntxwv kev ua tau zoo:
Hydraulic piston seals rau cov kauj ruam ua ke
1. Siab ≤ (MPa): 60/MPa
2. Kub: -45 ℃ to + 200 ℃
3. Ceev ≤(m/s): 15 m/s
4. Sealing khoom: NBR / PTFE FKM
5. Feem ntau siv hauv: piston pas nrig hauv hydraulic machinery, txheem lub tog raj kheej, tshuab cuab yeej, hydraulic xovxwm, thiab lwm yam.
Raws li ib qho tseem ceeb sealing ntaus ntawv xws li piston pas nrig foob thiab piston foob, yog hais tias muaj ib tug xau, nws yuav twv yuav raug hu cuam tshuam rau ib txwm ua hauj lwm ntawm lub tshuab thiab ua rau ib puag ncig puas.Yog li ntawd, kev sib txuas ua ke tsis yog tsuas yog nyob rau hauv static (static) seals, tab sis kuj nyob rau hauv dynamic (dynamic) foob tej yam kev mob yog ua tau kom ua tau tsawg heev to.
Tsis tas li ntawd, kev sib txhuam lub zog noj thiab hnav lub neej ntawm cov khoom siv sealing kuj muaj kev cuam tshuam zoo rau kev ua haujlwm zoo ntawm cov tshuab tshuab.Cov dej xau, kev siv hluav taws xob, hnav lub neej thiab lwm yam khoom tseem ceeb ntawm cov khoom sib xyaw ua ke thiab cov khoom siv ntawm lub foob nyob rau hauv kev ua haujlwm zoo sib xws rau lub siab thiab kev faib tawm ntawm qhov chaw sib cuag ntawm lub foob thiab lub piston pas nrig (los yog lub tog raj kheej phab ntsa. ).Nws yog hais txog kev cuam tshuam ntawm kev siv tshuab ua haujlwm tsis zoo ntawm cov khoom siv kho tshuab thiab kev ua haujlwm ntawm cov ntsaws ruaj ruaj.
