Mw'isi isaba gufunga inganda, Polytetrafluoroethylene (PTFE) ni ibikoresho byahawe agaciro kubera imiti idasanzwe yo kurwanya imiti, guterana amagambo make, ndetse n'ubushobozi bwo gukora mu bushyuhe bwinshi. Ariko, mugihe porogaramu zimutse ziva mubintu bihagaze neza - hamwe nihindagurika ryumuvuduko, ubushyuhe, hamwe nogukomeza - ibintu ubwabyo bituma PTFE igira akamaro birashobora kwerekana ingorane zikomeye zubuhanga.Iyi ngingo iracengera muri physics inyuma yimyitwarire ya PTFE mubidukikije bikora kandi ikanasuzuma ingamba zikuze, zemejwe zifasha gukoresha neza mubikorwa bikomeye biva mu kirere kugeza kuri sisitemu yimodoka ikora cyane.
Ⅰ.Ikibazo Cyibanze: Ibikoresho bya PTFE Mubigenda
PTFE ntabwo ari elastomer. Imyitwarire yayo mubibazo n'ubushyuhe bitandukanye cyane nibikoresho nka NBR cyangwa FKM, bisaba ubundi buryo bwo gushushanya. Inzitizi zibanze mugushiraho ikimenyetso ni:
Ubukonje butemba (Creep):PTFE yerekana impinduka zo guhindagurika muburyo bwa mashini ikomeje, ibintu bizwi nkubukonje cyangwa imigezi. Ikidodo gifite imbaraga, umuvuduko uhoraho hamwe no guterana amagambo birashobora gutuma PTFE ihinduka buhoro buhoro, biganisha ku gutakaza imbaraga za kashe ya mbere (umutwaro), hanyuma, kunanirwa kashe.
Modulus Ntoya:PTFE ni ibintu byoroshye ugereranije nibintu byoroshye. Bitandukanye na reberi O-impeta ishobora gusubira muburyo bwayo nyuma yo guhindura ibintu, PTFE ifite gukira guke. Mugihe cyumuvuduko ukabije wamagare cyangwa ubushyuhe bwihuse, uku kutihangana kurashobora kubuza kashe gukomeza guhuza hamwe nubuso bwa kashe.
Ingaruka zo Kwagura Ubushyuhe:Ibikoresho bifite imbaraga bikunze guhura nubushyuhe bukomeye. PTFE ifite coefficient yo hejuru yo kwagura ubushyuhe. Mugihe cy'ubushyuhe bwo hejuru, kashe ya PTFE iraguka, imbaraga ziyongera. Iyo imaze gukonja, irasezerana, ishobora gufungura icyuho igatera kumeneka. Ibi byiyongereyeho ibipimo bitandukanye byo kwagura ubushyuhe bwa kashe ya PTFE hamwe nicyuma cyamazu / shaft, bigahindura imikorere.
Utabanje gukemura ibyo bintu biranga ibintu, kashe ya PTFE yoroshye ntabwo yizewe mumirimo ikora.
.Gukemura ibisubizo: Uburyo Igishushanyo Cyubwenge Cyishyurwa Kubintu bigarukira
Inganda igisubizo kuri ibyo bibazo ntabwo ari ukwanga PTFE ahubwo ni ukuyongera binyuze mubushakashatsi bwubwenge. Intego nugutanga imbaraga zihamye, zizewe zifunga PTFE yonyine idashobora gukomeza.

Nibisubizo byiza kandi bikoreshwa cyane kubidodo bya PTFE. Ikidodo gikoreshwa n'amasoko kigizwe n'ikoti rya PTFE (cyangwa izindi polymer) zikubiyemo isoko y'icyuma.
Uburyo ikora: Isoko ikora nkisoko rihoraho, imbaraga-nyinshi. Ihora isunika iminwa ya PTFE hanze hejuru yikimenyetso. Nkuko ikoti rya PTFE ryambara cyangwa rikagira imbeho ikonje, amasoko araguka kugirango yishyure, agumane umutwaro uhoraho wo gufunga ubuzima bwa kashe.
Ibyiza Kuri: Porogaramu ifite umuvuduko ukabije wizuba, ubushyuhe bwagutse buringaniye, amavuta make, kandi aho igipimo cyo hasi cyane kirakomeye. Ubwoko busanzwe bwamasoko (cantilever, helical, canted coil) bwatoranijwe hashingiwe kumuvuduko wihariye nibisabwa.
2. Ibikoresho byose: Kuzamura PTFE bivuye imbere
PTFE irashobora kongerwamo ibyuzuzo bitandukanye kugirango itezimbere imiterere yubukanishi. Ibisanzwe byuzuza harimo fibre fibre, karubone, grafite, umuringa, na MoS₂.
Uburyo ikora: Iyuzuza igabanya umuvuduko ukonje, kongera imbaraga zo kwambara, kunoza ubushyuhe bwumuriro, no kongera imbaraga zo kwikuramo shingiro PTFE. Ibi bituma kashe iringaniye kandi igashobora kwihanganira ibidukikije.
Ibyiza Kuri: Kudoda imikorere yikimenyetso kubikenewe byihariye. Kurugero, ibyuzuye bya karubone / grafite byongera amavuta no kwambara birwanya, mugihe ibyuzuye byumuringa byongera ubushyuhe bwumuriro nubushobozi bwo gutwara ibintu.
3. Igishushanyo cya V-Impeta: Ikimenyetso cyoroshye kandi gifatika
Mugihe atari kashe yambere ya kashe ya kashe, PTFE ishingiye kuri V-impeta nibyiza kubikorwa byingirakamaro.
Uburyo ikora: V-impeta nyinshi zegeranye hamwe. Gucomeka kwa axial gukoreshwa mugihe cyo guterana bitera iminwa yimpeta kwaguka cyane, bigatera imbaraga zo gufunga. Igishushanyo gitanga ingaruka zo kwishura-kwambara.
Ibyiza Kuri: Kurinda ibyingenzi byambere kwanduza, gukora nkibikoresho byoroheje cyangwa umunwa wumukungugu, hamwe nogukoresha icyerekezo.
Ⅲ.Ibishushanyo byawe Kugenzura Urutonde rwa Dynamic PTFE Guhitamo Ikimenyetso
Guhitamo neza kashe ya PTFE, uburyo bwa sisitemu ni ngombwa. Mbere yo kugisha inama uwaguhaye isoko, kusanya aya makuru akomeye yo gusaba:
Umwirondoro Wumuvuduko: Ntabwo ari igitutu kinini gusa, ahubwo intera (min / max), inshuro yinzinguzingo, nigipimo cyimpinduka zumuvuduko (dP / dt).
Ikirere cy'ubushyuhe: Ubushyuhe ntarengwa kandi ntarengwa bwo gukora, kimwe n'umuvuduko w'ubushyuhe.
Ubwoko bwimikorere yubwoko: Kuzunguruka, kunyeganyega, cyangwa gusubiranamo? Shyiramo umuvuduko (RPM) cyangwa inshuro (cycle / umunota).
Itangazamakuru: Ni ayahe mazi cyangwa gaze bifunzwe? Guhuza ni urufunguzo.
Igipimo cyemewe cyo kumeneka: Sobanura ibintu byemewe byemewe (urugero, cc / hr).
Ibikoresho bya sisitemu: Igikoresho n'ibikoresho byo guturamo ni ibihe? Gukomera kwabo no kurangiza hejuru nibyingenzi kwambara.
Ibidukikije: Kuba hari ibintu byanduza, UV ihura, cyangwa ibindi bintu byo hanze.
Umwanzuro: Igishushanyo Cyiza cyo Gusaba Imbaraga
PTFE ikomeje kuba ikintu cyiza cyo gufunga ibidukikije bigoye. Urufunguzo rwo gutsinda ni ukwemera aho rugarukira no gukoresha ibisubizo bikomeye byubuhanga kugirango ubitsinde. Mugusobanukirwa amahame yinyuma yikidodo kiva mumasoko, ibikoresho bikomatanyije, hamwe na geometrike yihariye, injeniyeri zirashobora gufata ibyemezo byuzuye byemeza ko byizerwa igihe kirekire.Kuri Yokey, tuzobereye mugukurikiza aya mahame kugirango dushyireho ibisubizo bihamye neza. Ubuhanga bwacu bushingiye ku gufasha abakiriya kugendana nubucuruzi bugoye bwo guhitamo cyangwa gushushanya-gushushanya kashe ikora iteganijwe mugihe gikenewe cyane.
Ufite porogaramu igoye yo gushiraho ikimenyetso? Duhe ibipimo byawe, kandi itsinda ryacu ryubwubatsi rizatanga isesengura ryumwuga nibyifuzo byibicuruzwa.
