Uma kuqhathaniswa nezigxivizo zamafutha enjoloba, izigxivizo zamafutha e-PTFE zinezinzuzo eziningi
1. Uphawu lwamafutha enjoloba luthatha udebe olucijile olucindezelwa isiphethu, futhi indawo yokuxhumana ne-shaft ingu-0.3-0.5mm ububanzi kuphela.Uwoyela we-PTFE seal wamukela isakhiwo esishukumisayo sezindebe ezibanzi esingenantwasahlobo, futhi indawo yokuxhumana ene-shaft ingu-5-7mm ububanzi, ukuze ikwazi Ukugcina ifilimu kawoyela eyanele futhi ayizweli eccentricity ye-shaft.Isengasebenza ngokujwayelekile ngaphansi kwesimo sokusebenza se-0.4mm radial runout.
2. Udonga lwangaphakathi lophawu lukawoyela lwe-PTFE luqoshwe ngegroove yentambo ebhekene nokuzungezisa umgodi.Lapho i-shaft izungeza, i-thrust yangaphakathi ikhiqizwa ukuvimbela uketshezi ukuthi lungaphumi.Le thrust iphezulu kangangokuthi ingavala u-1.0MPa (udebe olulodwa), 3MPa (izindebe ezimbili) umfutho woketshezi, futhi uphawu lukawoyela wenjoloba luyi-0.03MPa kuphela.
3. Impahla elwa nokungqubuzana yophawu lwamafutha e-PTFE ifaneleka ngokukhethekile ukusebenza ngaphandle kwamafutha noma uwoyela omncane.Ngisho noma iqalwa kabusha ngemva kokuvalwa isikhathi eside, ingaba nezici zokungqubuzana ngokushesha.
4. I-PTFE oil seal ifaneleka ngokukhethekile izinhlelo zokusebenza zokuzungezisa ngesivinini esikhulu, futhi isivinini singafinyelela ku-30m/s.
5. I-Teflon oil seal ayikwazi ukufeza ukuvuza.
