Masale ana a fana ka ts'ehetso ea bohlokoa ho li-O-rings le litiiso tse ling tsa elastomeric, ho netefatsa ho ts'epahala le ho ts'epahala ha nako e telele lits'ebetsong tsa indasteri.
Lintlha tsa bohlokoa tsa PTFE Backup Rings
Khanyetso e Ikhethang ea Lik'hemik'hale
PTFE Backup Rings e tumme ka ho se sebetse ha eona ka lik'hemik'hale, e fana ka khanyetso e ke keng ea lekanngoa le mefuta e mengata ea lik'hemik'hale, ho kenyelletsa le li-acids, bases, solvents, le mafura. Sena se etsa hore e be tse loketseng ho sebelisoa libakeng tse senyang haholo moo lisebelisoa tse ling li ka senyehang.
Wide Temperature Range
PTFE e ka sebetsa ka katleho ho pholletsa le mocheso o pharaletseng, ho tloha ho mocheso oa cryogenic ho ea ho 500°F (260°C). Sena se feto-fetoha se tiisa hore PTFE Backup Rings e lula e sebetsa ebile e tšepahala mochesong o feteletseng le serame.
Coefficient e tlase ea Friction
PTFE e na le khohlano ea tlhaho e tlase, e fokotsang ho senyeha ha likarolo tsa ho nyalana le ho fokotsa tahlehelo ea matla. Thepa ena e boetse e thusa ho fokotsa kotsi ea ho ts'oaroa le ho ts'oaroa, ho netefatsa ts'ebetso e boreleli le tlas'a meroalo e phahameng.
Matla a Phahameng a Mechini
PTFE Backup Rings e etselitsoe ho mamella khatello e matla ea mochini le likhatello tse phahameng. Kaho ea bona e matla e thibela extrusion le deformation, ka hona ho matlafatsa ts'ebetso e akaretsang le nako e telele ea mokhoa oa ho tiisa.
Ha e na tšoaetso ebile e lumellana le FDA
PTFE ke ntho e sa silafatsang, e etsang hore e tšoanelehe bakeng sa lits'ebetso moo bohloeki le bohloeki li leng bohlokoa, joalo ka indastering ea ho lokisa lijo, ea meriana le ea semiconductor. Li-backup Rings tse ngata tsa PTFE li fumaneha hape ka limaraka tse lumellanang le FDA, ho netefatsa hore li fihlela litekanyetso tse thata tsa taolo.
Lisebelisoa tsa PTFE Backup Rings
Litsamaiso tsa Hydraulic le Pneumatic
PTFE Backup Rings li sebelisoa haholo ka hydraulic cylinders, actuators, le tsamaiso ea pneumatic ho thibela seal extrusion le ho boloka ho tiisa botšepehi tlas'a khatello e phahameng. Khohlano ea bona e tlase le ho hanyetsa ha bona ho boetse ho kenya letsoho ho fokotseng tlhokomelo le bophelo bo atolositsoeng ba ts'ebeletso.
Tšebeliso ea Lik'hemik'hale
Limeleng tsa lik'hemik'hale, PTFE Backup Rings e fana ka tšehetso e tšepahalang bakeng sa litiiso tse pepesehileng lik'hemik'hale tse mabifi, li-acids le solvents. Boiketlo ba bona ba lik'hemik'hale bo tiisa ts'ebetso ea nako e telele ntle le ho senyeha.
Sepakapaka le Tšireletso
PTFE Backup Rings ke likarolo tsa bohlokoa lits'ebetsong tsa hydraulic tsa sefofane, lisebelisoa tsa ho lulisa, le lits'ebetso tse ling tse sebetsang hantle haholo. Bokhoni ba bona ba ho mamella mocheso le likhatello tse feteletseng bo etsa hore e be tse loketseng bakeng sa ho netefatsa polokeho le ts'epahalo libakeng tsa sepakapaka.
Indasteri ea Likoloi
Lits'ebetsong tsa likoloi, PTFE Backup Rings e sebelisoa lits'ebetsong tsa phetisetso, lits'ebetsong tsa motlakase, le lits'ebetsong tsa mariki ho matlafatsa ts'ebetso ea ho tiisa le ho tšoarella. Khohlano ea bona e tlase le ho hanyetsa ha bona ho kenya letsoho ho ntlafatseng ts'ebetso le ho fokotsa tlhokomelo.
Phetoho ea Lijo le Meriana
Liindastering moo tšilafalo e lokelang ho qojoa, PTFE Backup Rings e netefatsa hore litiiso li lula li hloekile ebile li sa sebetse. Limaraka tsa bona tse lumellanang le FDA li bohlokoa haholo lits'ebetsong tse kenyelletsang lijo, meriana le lisebelisoa tsa bongaka.
Hobaneng u Khetha PTFE Backup Rings?
Ts'ebetso e Ntlafetseng ea Tiiso
PTFE Backup Rings haholo fokotsa kotsi ea tiiso extrusion le deformation, ho etsa bonnete ba hore litiiso tsa mantlha li boloka botšepehi ba tsona le tlas'a maemo a feteletseng. Sena se lebisa ts'ebetsong e tšepahalang le e se nang ho lutla.
Ho feto-fetoha ha maemo le ho tšoarella
Ka mefuta e mengata ea mocheso, khanyetso ea lik'hemik'hale, le matla a mochine, PTFE Backup Rings e loketse mefuta e mengata ea likopo. Ho tšoarella ha bona ho netefatsa bophelo bo bolelele ba ts'ebeletso le ho fokotsa litšenyehelo tsa tlhokomelo.
Ho Itloaetsa le Boteng
Li-backup Rings tsa PTFE li fumaneha ka boholo bo fapaneng, libopeho le limaraka tse fapaneng ho fihlela litlhoko tse ikhethang tsa kopo. Baetsi ba bangata ba boetse ba fana ka tharollo ea tloaelo ho rarolla mathata a ikhethang.
Tharollo e Sebeletsang Litšenyehelo
Le hoja PTFE e le thepa e sebetsang hantle haholo, chelete ea ho boloka litšenyehelo ho tloha tlhokomelong e fokotsehileng, bophelo bo atolositsoeng ba tšebeletso, le ts'ebetso e ntlafetseng ea tsamaiso e etsa hore PTFE Backup Rings e be khetho e theko e tlaase bakeng sa likopo tse hlokang chelete.
