Izinto zokusetshenziswa zePTFE gasketsbanezinga lokushisa elitholakalayo kanye namanani obubanzi bengcindezi yokusebenza.Ama-gaskets amaningi awakwazi ukusetshenziselwa izinga lokushisa eliphezulu kanye nengcindezi ephezulu yokusebenza.Lapho ukhetha i-gasket, kufanele iqale yamukelwe ngokuya ngokushisa kokusebenza kwe-gasket, ingcindezi yangempela yokusebenza, kanye nenani le-Pr.
Izinto zokusetshenziswa zePTFE gasketsbanezinga lokushisa elitholakalayo kanye namanani obubanzi bengcindezi yokusebenza.Ama-gaskets amaningi awakwazi ukusetshenziselwa izinga lokushisa eliphezulu kanye nengcindezi ephezulu yokusebenza.Lapho ukhetha i-gasket, kufanele iqale yamukelwe ngokuya ngokushisa kokusebenza kwe-gasket, ingcindezi yangempela yokusebenza, kanye nenani le-Pr.
Izinto zokusetshenziswa zama-gaskets e-PTFE kumele zimelane nokugqwala kwamakhemikhali nokugqwala komzimba.Ama-gaskets afanelekile kufanele asetshenziswe ngokuya ngezinhlobo zangempela zezinto ezisebenzayo kanye nezici zokugqwala, bese kucatshangelwa ukumelana nokugqwala kwe-hydrodynamic kwezinto zokusetshenziswa kwe-gasket.Ukumelana nokugqwala kwe-hydrodynamic ngokuvamile kuboniswa ukwanda kogqinsi nesisindo sengqikithi yezinto ze-gasket ngemva kokungena koketshezi.Kuma-gaskets athinta izinto ezingezona ezepulasitiki, ukugcina izinga elifanele lokunyuka kokuqina kwezinto ze-gasket kunenzuzo ekuthuthukiseni ukusebenza kokuvala ngaphansi kwesisekelo sokuqinisekisa ezinye izakhiwo.
Izinga lokuphumula le-PTFE gasket liyipharamitha eyinhloko yokuhlaziywa kwekhwalithi yokusebenza kwempahla ye-gasket.Ikhombisa ikhono lento ye-gasket ukumelana nokuphumuza ingcindezi kanye nokuwohloka kwe-creep.jikelele.Uma kuncane isilinganiso sokuphumula kwe-creep, kukhulu ukucindezeleka kwangaphakathi phakathi nomsebenzi.Ukusebenza okungcono kokuvala ama-gaskets angewona ama-asbestos.Ukuphumula kwe-Creep kuyisizathu esiyinhloko sokuvuza kwe-looper flange phakathi nomjikelezo wokusebenza.Idlala umphumela wokuthatha izinqumo empilweni yesevisi yoxhumano.Ukusebenza kokuncipha kwe-PTFE gasket kukhombisa i-ductility noma ukuguqulwa kwepulasitiki kwe-gasket ngaphansi komphumela womthwalo wesikhashana.Ukulungisa ukushiyeka okuhlukahlukene kwendawo ye-flange.Ngokulandelayo, ukusebenza kokuvimbela ukuvuza.
Ngokuvamile, ukusebenza okunciphayo okuningi kwama-non-asbestos gasket kungabhekwa njengemithetho yokuvala uphawu.Uma kuqhathaniswa nokunwetshwa, ukusebenza kokuqina kuyinkomba ebaluleke kakhulu.Ukusebenza kokuqina kubhekisela ekunxephezelweni kwe-ductility ye-gasket, engalandela ukuhlukaniswa kwe-flange ngenxa yezinga lokushisa noma umthwalo wemishini yemishini ukugcina uphawu.Ukusebenza kwe-PTFE gasket wukusebenza okuphelele okuyinhloko kwekhwalithi ye-gasket, futhi izinga lokuvuza liyinani lenkomba elibonakalayo.Ngokusekelwe enanini lenkomba yesilinganiso sokuvuza, ikhono lokuvala i-gasket lingahlaziywa ngokwenani futhi liqhathaniswe.Izinga lokuvuza ipharamitha eyisisekelo okufanele icatshangelwe lapho kukhethwa ama-gaskets.
Izinto Ezi-4 Okumele Uzikhathaze Lapho Ufaka I-PTFE Gaskets
1. Umugqa wokuvala noma indawo ephakanyisiwe ye-PTFE gasket seal akumele yonakaliswe.I-PTFE gasket seal ekubukeni kohlelo ingasebenzisa izimbobo zangaphakathi kwesokunxele nakwesokudla.Ukusebenza kokuvala kwe-PTFE gasket seal yomshini we-hydraulic kusekelwe ikakhulukazi ku-shaft noma umgodi.Umugqa womlomo ohambisana kahle kufanele uqaphe kakhulu kuyo yonke inqubo yokufaka, ukuthutha, nokugcinwa.Le ngxenye yenziwe nge-graphite ethambile futhi eqinile, i-chemical fiber, irabha, nepulasitiki ekwazi ukumelana nokugqwala, izinga lokushisa eliphezulu nokuguga.Ibhodi le-insulation nezinye izinto ezinjalo ezisengozini zakhiwe ngezinto, ngakho-ke uma zonakalisiwe, kuzodala ingozi enkulu efihliwe engxenyeni yokuvala.
2. Uma ufaka i-PTFE gasket seal, kufanele siqaphe kakhulu, futhi inqubo yokufaka kufanele yenziwe kancane kancane.Phakathi nayo yonke inqubo yokufaka, ungaphoqi ukufakwa ngokuma okukhulu kakhulu, okuzokwenza i-PTFE gasket seal yawo wonke umuntu.Isakhiwo sokuqala esakhiwe ngaphambili sacekelwa phansi.
3. Ukufakwa kwezimpawu ze-PTFE gasket kumele kuhambisane nokulinganisa nokulinganisela.Lapho ufaka, beka i-PTFE gasket seal endaweni yodebe olunamathele (noma indawo ephakanyisiwe enengqondo) ukuze ugweme umsebenzi wesofthiwe yesistimu Phakathi nayo yonke inqubo, ngenxa yoshintsho (isibonelo, ukwanda) kwezimo zayo zokusebenza, ukwehluleka okubangelwa ngokuvuza okuncane kwenzeka.Kudingekile ukuthi uhlale ubheka futhi wenze umsebenzi omuhle esinyathelweni esilandelayo se-PTFE gasket seal.
4. I-PTFE gasket inokusebenza okuphelele, ukumelana nokushisa, ukumelana nokugqwala, okungagxili, ukuzigcoba, ukusebenza kwe-electrochemical, kanye nokumelana nokungqubuzana okuphansi kakhulu.
Njengemikhiqizo yenjoloba, ama-gaskets e-PTFE ashintshiwe angenziwa abe amapayipi e-polytetrafluoroethylene, izinduku, amabhande, amapuleti, amafilimu epulasitiki, njll. Ngokuvamile asetshenziswa kumapayipi amelana nokugqwala, izitsha, amaphampu, ama-valve kanye nokutholwa kwawo kwe-radar yokulawula, ukuxhumana kwe-high-frequency. okokusebenza, okokusebenza kokuxhumana okungenantambo, njll.
Zonke izigcwalisi ezingathwala izinga lokushisa lokubala le-PTFE zengezwe ku-tetrafluoroethylene gasket eguquliwe.Izinhlobo zokugcwalisa zifaka i-glass fiber, izinto zensimbi, i-metalized metal oxides, i-high-purity graphite, i-molybdenum disulfide, i-carbon fiber soft, ifilimu ye-Polyimide, njll., ukusebenza kwayo kwemishini yemishini kungathuthukiswa kakhulu.Ngaphezu kwalokho, ezinye izakhiwo ze-PTFE zingagcinwa, futhi ukumelana nokugqoka kanye nenani le-PV kungandiswa izikhathi ezingu-1000.
