Hydraulic U-Cup Piston Seals - Siab-Lub Hwj Chim Dynamic Fluid Power
Hauv siab -tonnage fluid power systems, theU-Cup Seal(feem ntau categorized feem ntau raws li U-Nplhaib lossis Y-Nplhaib) yog tus neeg ua haujlwm tsis muaj kev sib cav. Nruab sab hauv hauv hydraulic kheej kheej,U-Cup Piston Sealsyog ua haujlwm nrog kev tswj hwm lub zog los ntawm kev tiv thaiv cov kua dej hla hla lub taub hau piston, thaumU-Cup Rod Sealskhaws cov kua dej siab kom muaj nyob hauv lub tog raj kheej. Nyob rau hauv huab cua dynamic loads, cov ntsaws ruaj ruaj yuav tsum tiv thaiv extrusion, tiv taus siab heev spikes, thiab tuav tsis tshua muaj kev sib txhuam thaum lub sij hawm nruam oscillation.
Xiamen Best Seal tsim cov haujlwm hnyav -Hydraulic U-Cup Sealsengineered tshwj xeeb rau mobile hydraulics, industrial presses, thiab hnyav lub ntiaj teb - txav khoom. Siv high-modulus Polyurethane (PU), Nitrile (NBR), thiab cov fluorocarbons muaj zog, peb cov U-Khoos feature precision-moulded dynamic di ncauj uas harness system siab kom nquag sealing quab yuam. Los ntawm cov qauv symmetrical rau txoj kev thauj khoom / lub zog tsim qauv, peb xa cov cim dynamic foob geometry xav tau rau koj lub tog raj kheej tshwj xeeb.

Hydraulic Fluid Power FAQ
Q: Dab tsi yog "Loaded" U- khob, thiab thaum twg nws tsim nyog?
Ib lub khob ntim U-khob nta ib lub nplhaib O-nplhaib (lossis zoo sib xws energizer) haum rau hauv "U" channel. Qhov no muab tam sim ntawd qis qis - lub zog radial sealing quab yuam thiab tiv thaiv daim di ncauj los ntawm kev sib tsoo nyob rau hauv kev vibration hnyav lossis poob siab tam sim ntawd. Nws yog qhov pom zoo heev rau qhov chaw siab tsis zoo.
Q: U-Nplhaib puas tuaj yeem hloov O-Nplhaib kom ruaj ntseg?
Yog tias daim ntawv thov koom nrogdynamic reciprocating motion, U-Nplhaib yuav tsum hloov O-Nplhaib kiag li. O-Rings feem ntau yog rau kev sib khi zoo li qub; Yog tias siv dynamically nyob rau hauv siab, lawv yuav twist (kauv tsis ua hauj lwm) thiab extrude. U-Cov khob yog qhov profile tshwj xeeb- tau tsim kho rau kev sib txhuam kev taw qhia.
