Compressor PTFE roj foob
PTFE roj foob
- Compressor Piston Rings: Piston rings feem ntau yog siv nruab nrab ntawm lub tog raj kheej thiab lub piston los kaw lub tog raj kheej thiab txo kev sib txhuam ntawm lub tog raj kheej phab ntsa thiab lub piston. PTFE roj foob tuaj yeem siv los ua cov khoom siv piston los muab kev sib txhuam qis thiab hnav tsis kam.
- Compressor valve phaj seals (Valve Plate Seals): Valve phaj seals yog siv los kaw qhov chaw nruab nrab ntawm lub compressor valve phaj thiab lub tog raj kheej kom ntseeg tau tias cov roj tsis xau. PTFE roj foob tuaj yeem siv los muab kev sib khi ua haujlwm zoo thiab tiv thaiv roj to.
- Compressor shaft seals (Ncej Seals): Compressor shaft seals yog siv los kaw qhov chaw nruab nrab ntawm cov ncej thiab cov kabmob kom tsis txhob muaj cov roj nplua nyeem lossis cov tub yees tso tawm. PTFE roj foob feem ntau yog siv rau cov ntsaws ruaj ruaj vim lawv cov tshuaj tiv thaiv zoo heev thiab tsis tshua muaj coefficient ntawm kev sib txhuam.
- Compressor Pump Body Seals: Hauv qee hom compressor, lub twj tso kua mis lub cev yog siv los kaw qhov sib koom ua ke ntawm lub twj tso kua mis lub cev thiab lub twj tso kua mis kom tiv thaiv kom tsis txhob muaj kua hauv lub twj tso kua mis. PTFE roj foob tuaj yeem siv los muab kev ruaj ntseg sealing kev ua tau zoo tiv thaiv cov kua xau.
- PTFE (polytetrafluoroethylene) piston nplhaib siv nyob rau hauv lub compressor yog ib tug tshwj xeeb piston nplhaib ua los ntawm PTFE khoom.
- Khoom Siv Khoom: PTFE yog cov khoom siv polymer nrog cov tshuaj zoo heev inertness thiab corrosion kuj. Nws tiv taus ntau yam tshuaj, nrog rau cov kua qaub, alkalis, cov kuab tshuaj thiab corrosive gases. Qhov no tso cai rau PTFE piston rings siv nyob rau hauv ib puag ncig nyob rau hauv kev sib cuag nrog corrosive media thiab tswj kev ua haujlwm ruaj khov.
- Self-lubricating: PTFE muaj qhov zoo ntawm nws tus kheej lubricating zog, txo cov kev sib txhuam ntawm lub nplhaib piston thiab lub tog raj kheej phab ntsa. Qhov no yuav pab txo qis zog poob, txo qhov hnav thiab txuas ntxiv lub neej kev pab cuam ntawm lub nplhaib piston.
- Tsis tshua muaj kev sib txhuam coefficient: PTFE piston rings muaj qhov tsis tshua muaj kev sib txhuam coefficient, tso cai rau lub piston txav tau yooj yim dua hauv lub tog raj kheej thaum ua haujlwm. Qhov no pab txhim kho kev ua haujlwm ntawm lub compressor thiab txo kev siv zog.
- Hnav tsis kam: PTFE cov khoom muaj qhov hnav tsis kam thiab tuaj yeem siv tau ntev hauv kev sib hloov ceev thiab kev sib txhuam yam tsis tau hnav yooj yim. PTFE piston rings muab kev sib khi ntev ntev thiab tiv thaiv lub tog raj kheej phab ntsa los ntawm kev hnav ntau dhau.
- Kub adaptability: PTFE muaj qhov kub thiab txias tsis kam thiab muaj peev xwm ua haujlwm ntawm qhov kub siab dua yam tsis poob nws cov khoom. Qhov no ua rau PTFE piston rings haum rau kub compressor daim ntaub ntawv xws li cua compressors thiab tub yees compressors.
