Izingxenye ezithwalayo zingatholakala ekufakweni nge-bolting, i-tack-welding, i-welding egcwele noma i-mortar embedment, futhi uhlobo olufanele lokuthwala kufanele lukhethwe ngokuvumelana nendlela yokufaka.I-PTFE kufanele ivikeleke ngokwanele ngokumelene ne-weld spatter, isifutho sikapende, i-swarf yensimbi njll, ngesikhathi sokufakwa.
Kuhlelo olubanzi lwezinhlelo zokusebenza, ama-PTFE Slide bearings angaphezulu kwamapuleti okunweba avamile, amarola nezisekelo zohlobo lwengalo yerocker.Basekela imboni ye-petrochemical, imishini esindayo, amapayipi, izakhiwo kanye namabhuloho amabhuloho;zivumela ukunwetshwa, ukufinyela nokunye ukunyakaza okuhambisanayo kwanoma isiphi isakhiwo esinyakazayo ngenxa yamandla ashisayo, azamazama komhlaba noma ahlukanisayo.
Amabhorethi ezicelo ezinjalo kufanele asebenze ngemithwalo ephezulu nesivinini esiphansi, futhi kungaphansi kwalezi zimo lapho izakhiwo zokuzithambisa ze-PTFE zisezingeni eliphezulu.Lesi sici, kanye nezici zayo zokungasheleli nokungasheleli kwesimo sezulu, isizathu esiyinhloko esenza i-PTFE ibonakale iphumelela kangaka njengento ephethe ama-slide.
Izinzuzo
1 Ubulula bedizayini yebhere kanye nokulula kwayo ukwenziwa nokufakwa kwenza iyunithi ingabizi kakhulu.2 Izindleko zokwakha zingancishiswa ngokuklama ukunweba esikhundleni sokucindezeleka.3 Isambatho sokungqubuzana phezu kwendawo eyibhodi ihlala ingashintshi, ngisho nangaphansi. izimo ezimbi kakhulu.4 Ama-bearings awanawo ukugcinwa - PTFE iyazithambisa ngokwemvelo, kuyilapho izinhlayiya zokungcola zimuncwa kokubalulekile.Ukuvikelwa okulula kuphela kuyadingeka ngokumelene nokungena okubalulekile kokungcola.
Ama-Coefficients of Friction
I-coefficient of friction yezinto ze-PTFE incike ezinhlobonhlobo eziningi, okuhlanganisa ingcindezi, isivinini esishelelayo kanye nezinga lokushisa.Umbono uhlukene mayelana nomthelela wezinye eziguquguqukayo, nakuba kuvunyelwene ngokuthi umfutho ophezulu nesivinini esiphansi kuvumela ukungqubuzana okuphansi.
I-coefficient incane kunanoma iyiphi enye into eqinile yobunjiniyela.Kubikwe ngokuhlukahluka kusuka ku-0.02 kuye ku-0.2, kepha lokhu kuncike ekulungisweni kwendawo kanye nendlela yokuhlola.Ishadi lomthwalo/lengxabano libonisa umphumela womthwalo.
Ngokuvamile, i-coefficient yokungqubuzana phakathi kwendawo yokukhwelana kanye nephedi eliphethe isilayidi le-PTFE lizoba okungenani uma ingcindezi ku-PTFE iphezulu (ihambisana nemikhawulo eyamukelekayo yokukhasa), ukuthwala kwenziwa kusuka ku-PTFE engagcwalisiwe, futhi isiphetho sendawo yokukhwelana icwebezeliswe kakhulu.
Ukwengeza, esinye sezici zokungqubuzana ezibaluleke kakhulu ze-PTFE ukungabikho 'kwe-stick-slip', ngoba ngokungafani nawo wonke amanye ama-bearings avamile, ukungqubuzana okumile kwe-PTFE kuyalingana noma kuphakeme kancane kunokungqubuzana okuguquguqukayo.
