Iiringi ze-PTFE Backup-up

Inkcazo emfutshane:

Iiringi ze-PTFE Backup-up zizinto ezibalulekileyo kwiinkqubo zokuvala ezinoxinzelelo oluphezulu, ezenzelwe ukuqinisa izitywino eziphambili ezifana neeringi ze-O kunye nokuthintela ukuphuma phantsi koxinzelelo olukhulu loomatshini. Zenziwe nge-polytetrafluoroethylene (PTFE), ezi ringi zibonisa ukungangeni kakuhle kweekhemikhali, zichasa phantse zonke izinto ezihlaselayo kuquka ii-asidi ezinamandla, ii-alkali ezinamandla, izinyibilikisi zendalo, kunye neegesi ezirhabaxa. I-coefficient yazo ephantsi kakhulu yokungqubana kunye nozinzo olubalaseleyo lwemilinganiselo zivumela ukusebenza okuthembekileyo kwizicelo eziguquguqukayo kunye namaqondo obushushu aqala kwi--200°C ukuya kwi-+260°C. Amandla aphezulu okuxinzelela kunye neempawu ezingaguqukiyo ziqinisekisa ukusasazwa komthwalo ofanelekileyo, zikhusela ngokufanelekileyo izitywino ze-elastomeric ekuqhumeni okanye ekonakalisweni ngexesha lokutshintsha koxinzelelo. Ngeempawu ezingezizo zokunamathela kunye nokuthobela i-FDA/USP Class VI apho kufuneka khona, iiringi ze-PTFE Backup-up zisetyenziswa kakhulu kumashishini abalulekileyo afana nezixhobo ze-oyile negesi, ii-reactors zokucubungula iikhemikhali, iinkqubo ze-hydraulic, kunye noomatshini bamayeza abafuna ukusebenza ngaphandle kongcoliseko. Ukudibanisa kwazo ukungangeni kweekhemikhali kunye nokuqina koomatshini kuzenza zibe yinto ebalulekileyo ekugcineni ukuthembeka kwesitywino kwiindawo zokusebenza ezinzima.

Yintoni iiRings ze-PTFE Backup-up

Iiringi ze-PTFE (Polytetrafluoroethylene) Backup zizinto ezibalulekileyo kwiinkqubo zokuvala, ezenzelwe ngokukodwa ukuthintela ukuphuma kunye nokuguqulwa kwezitywina eziphambili phantsi koxinzelelo oluphezulu kunye neemeko ezinzima. Ezi ringi zibonelela ngenkxaso ebalulekileyo kwiiringi ze-O kunye nezinye izitywina ze-elastomeric, ziqinisekisa ukuthembeka kwexesha elide kunye nokuthembeka kwizicelo ezifunwayo zoshishino.

Iimpawu eziphambili zeeringi ze-PTFE Backup

Ukumelana neekhemikhali okungaqhelekanga

Iiringi ze-PTFE Backup ziyaziwa ngokungangeni kweekhemikhali, zibonelela ngokumelana okungenakuthelekiswa nanto kwiikhemikhali ezahlukeneyo, kuquka ii-asidi, iziseko, izinyibilikisi kunye namafutha. Oku kuzenza zilungele ukusetyenziswa kwiindawo ezinobuthi kakhulu apho ezinye izinto zingonakalisa khona.

Uluhlu lobushushu obubanzi

I-PTFE inokusebenza ngempumelelo kububanzi bobushushu, ukusuka kumaqondo obushushu angabonakaliyo ukuya kuma-500°F (260°C). Oku kuguquguquka kuqinisekisa ukuba ii-PTFE Backup Rings zihlala zisebenza kwaye zithembekile kubushushu obugqithisileyo nokubanda.

I-Coefficient ephantsi yokungqubana

I-PTFE inomlinganiselo ophantsi wokungqubana, nto leyo enciphisa ukuguguleka kwezinto ezidibanayo kwaye inciphise ukulahleka kwamandla. Le propati ikwanceda ekunciphiseni umngcipheko wokurhawuzelelwa nokubanjwa, ukuqinisekisa ukusebenza kakuhle naphantsi kwemithwalo ephezulu.

Amandla aphezulu oomatshini

Iiringi ze-PTFE Backup zenzelwe ukumelana noxinzelelo olukhulu loomatshini kunye noxinzelelo oluphezulu. Ulwakhiwo lwazo oluqinileyo luthintela ukuphuma kunye nokuguquguquka, ngaloo ndlela luphucula ukusebenza ngokubanzi kunye nobude bexesha lenkqubo yokutywina.

Ayingcolisi kwaye ayithobeli i-FDA

I-PTFE yinto engangcolisiyo, nto leyo eyenza ukuba ifaneleke ukusetyenziswa apho ucoceko nobunyulu bubaluleke kakhulu, njengakwimizi-mveliso yokulungisa ukutya, amayeza, kunye ne-semiconductor. IiRings ezininzi ze-PTFE Backup Rings nazo ziyafumaneka kwiiklasi ezihambelana ne-FDA, ukuqinisekisa ukuba ziyahlangabezana nemigangatho engqongqo yokulawula.

Usetyenziso lweeRings ze-PTFE Backup

Iinkqubo zeHydraulic kunye nePneumatic
