NBR / FKM Dub Back Up Nplhaib Rau Tus Kheej

Lub nplhaib rov qab yog lub nplhaib sib dhos uas tuav lub elastomeric foob rau nws cov qauv tsim thiab hauv nws qhov chaw raug. Cov thaub qab ntiv nplhaib feem ntau siv nrog O-Rings los tiv thaiv kev txhaws ntawm kev kub siab.

Thaum khi lub piston sab hauv pneumatic lub tog raj kheej, cov khoom muag muag thiab yoog raws yog qhov yuav tsum tau ua kom tsis txhob xau. Txawm li cas los xij, cov khoom qub no tuaj yeem tso cov khoom foob uas cuam tshuam los ntawm kev rub tawm ntawm nws lub rooj zaum thiab tom qab ntawd pinched lossis nraus hauv qhov chaw nqaim ntawm piston thiab lub tog raj kheej phab ntsa. Yog tias qhov sib koom tes tsis tuaj yeem tsim kho dua, los yog siv cov elastomer tiv taus ntau dua, qhov kev daws teeb meem yuav ncaj qha ncaj qha nrog cov khoom siv stiffer. Hauv qhov no, nyob rau hauv daim ntawv ntawm lub zog sab hauv lub nplhaib.

ob txoj hlua thim rov qab tiv thaiv kev rho tawm

Cov kauj ruam rov qab feem ntau yuav siv rau cov ntawv thov nquag dua 100 bar, thiab daim ntaub ntawv zoo li puag ncig 950 bar. Txhua daim ntawv thov tuaj yeem sib txawv, yog li ntawd nws yog qhov yuav tsum tau siv qhov no raws li kev qhia dav dav xwb.

Muaj peb hom PTFE rov qab ua ib ncig: - khoom, kauv kiav txhab, thiab phua. Khoom Ua Si Sib Tsoo PTFE rov qab tuaj yeem nyuaj rau nruab. Vim tias PTFE tsis resilient, lub nplhaib rov qab yuav tsum tau "kho dua tshiab" tom qab ntsia rau hauv qhov zawj kom xa rov qab mus rau lawv qhov ntev. Muab kauv kiav txhab thiab muab cov hlua khi PTFE rov qab kov yeej qhov teeb meem no. Lawv tuaj yeem qhib me ntsis thaum lub sijhawm teeb tsa yam tsis cuam tshuam lawv.
