Izimpawu ze-PTFE Shaft

Lapho Kutholakala Izimpawu Zesivinini Esikhulu

Isivinini esiphezulu se-rotary shaft seals sitholakala ezinhlelweni eziningi.Izibonelo zingabandakanya okokusebenza kwe-cryogenic deflashing, amaphampu evacuum, ama-torpedo shaft seal, iziqalisi zenjini ye-turbine yegesi, namaphampu e-dredge angaphansi kwamanzi.Amamotho e-AC/DC avame ukudinga ama-shaft seal anesivinini esiphezulu, futhi angatholakala ezintweni ezifana nezinsimbi zokuphotha zamathuluzi e-CNC nezinsimbi zamazinyo noma zokuhlinza.

Ukusebenza Okushelelayo

Olunye udaba olubalulekile olunama-seal anesivinini esikhulu isidingo sokusebenza kahle, okusho ukugwema izinkinga ezifana ne-stick-slip.I-PTFE iwumsebenzi ofanelekile wokugwema ukushelela kwenduku, futhi isekela ukusebenza okubushelelezi, okuthule.

Ukungqubuzana

I-Friction ingenza noma iphule uphawu olunesivinini esikhulu.Ngesivinini esiphezulu, imiphumela yokungqubuzana inomthelela omkhulu ekusebenzeni kwezimpawu.Izigxivizo ze-Shaft zidinga ukungqubuzana okuphansi kakhulu, futhi njengoba ezinye izinhlelo zokusebenza zingase zivimbele ukusetshenziswa kwezinto zokugcoba, kunethuba elihle lokuthi impahla ye-polymer efanelekile yophawu lwesivinini esikhulu izozigcoba ngokwayo.

I-PTFE ilungele ukubhekana nale nselele ngoba ine-coefficient ephansi kakhulu yokungqubuzana kwanoma iyiphi into eyaziwa ngumuntu, futhi iyazigcoba ngokwayo.

Amazinga Okushisa Aphakeme

Enye yezinselelo eziyinhloko ku-high speed shaft seal ukulawula izinga lokushisa.Isivinini esiphezulu siholela ekwandeni kokukhiqizwa kokushisa.Ukukhiqizwa kokushisa kuholela ekushintsheni kobukhulu, okusho ukuthi uphawu lwesivinini esikhulu ludinga ukuba ne-coefficient encane yokwandisa ukushisa ukuze kuqinisekiswe ukuzinza kwe-dimensional.

Omunye umgomo uwukuqhuba ukushisa kude ne-seal, okusho ukuthi kanye ne-coefficient encane yokwandisa okushisayo impahla yophawu idinga ukuba ne-coefficient ephezulu ye-thermal conductivity.Nokho, akukona konke ukushisa okungaqhutshwa.Isigxivizo esinesivinini esikhulu sidinga ukwenziwa ngento ekwazi ukumelana namazinga okushisa aphezulu.

I-PTFE ingenza kahle emazingeni okushisa afika ku-500°F.Ine-thermal conductivity enhle engathuthukiswa kakhulu kusetshenziswa izigcwalisi zekhabhoni, futhi ine-coefficient ephansi yokwanda okushisayo okungathuthukiswa ngokusebenzisa izigcwalisi ezifana nengilazi nekhabhoni.

Ukusebenza kahle

Njengoba sekushiwo, izigxivizo ze-shaft zejubane eliphezulu zivame ukusetshenziswa ngama-AC/DC motors.Lezi zivame ukuba zincane futhi zingase zinikwe amandla ebhethri, okwenza ukusebenza kahle kube yinto ebaluleke kakhulu.Uma ukulahlekelwa kungancishiswa, ukusebenza kahle kungakhuliswa futhi kube nomthelela omuhle empilweni yebhethri.Okubalulekile okushayisanayo okuphansi okukhuthaza ukusebenza okushelelayo kubalulekile kulezi zinhlobo zezinhlelo zokusebenza, futhi i-PTFE ihambisana naleyo bhili.
