iyini i-Spring Seal/Spring Energized Seal/Variseal?

I-Spring Seal/Spring Energized Seal/Variseal iyisici sokuvala esisebenza kahle kakhulu esine-Teflon emise okwe-U yentwasahlobo ekhethekile.Ngokusebenzisa amandla afanelekile asentwasahlobo kanye nokucindezela koketshezi lwesistimu, udebe oluvalayo (ubuso) luyaphushelwa ngaphandle futhi lucindezelwe ngobumnene endaweni yensimbi evalwayo ukuze kukhiqizwe umphumela omuhle kakhulu wokuvala.Umthelela wokusebenza wentwasahlobo unganqoba ukugqama okuncane kwendawo yokukhwelana yensimbi nokuguga kodebe oluvalayo, kuyilapho kugcinwa ukusebenza okulindelekile kokuvala.

I-Teflon (PTFE) iyimpahla yokuvala enokumelana namakhemikhali okuphakeme nokumelana nokushisa okuhle uma kuqhathaniswa nerabha ye-perfluorocarbon.Ingasetshenziswa kuketshezi oluningi lwamakhemikhali, izincibilikisi, kanye namafutha asebenzisa amanzi kanye nokugcoba.Ikhono layo lokuvuvukala eliphansi livumela ukusebenza kokuvala isikhathi eside.Imithombo ehlukahlukene ekhethekile isetshenziselwa ukunqoba izinkinga ezinwebekayo ze-PTFE noma amanye amapulasitiki enjoloba asebenza kahle kakhulu, Izigxivizo ezithuthukisiwe ezingangena esikhundleni sezinhlelo eziningi zokusebenza ezimile noma eziguquguqukayo (eziphindaphindayo noma ezijikelezayo), ngezinga lokushisa elisuka kufriji ukuya ku-300 ℃. , kanye nebanga lokucindezela ukusuka ku-vacuum kuya ku-ultra-high pressure engu-700kg, nesivinini sokunyakaza esingafika ku-20m/s.Iziphethu zingasetshenziswa oketshezini oluhlukahlukene olushisa kakhulu olusezingeni eliphezulu ngokukhetha insimbi engagqwali, i-Elgiloy Hastelloy, njll. ngokuya ngezindawo ezihlukene zokusetshenziswa.

Uphawu lwasentwasahloboingenziwa ngokwezinga le-AS568AO-ringi-groove (njenge-radial shaft seal,piston seal, i-axial face seal, njll.), ishintsha ngokuphelele i-O-ring yendawo yonke.Ngenxa yokuntuleka kokuvuvukala, ingagcina ukusebenza kahle kokuvala uphawu isikhathi eside.Isibonelo, kuma-mechanical shaft seal asetshenziswa ezindaweni ezishisa kakhulu ezisezingeni eliphezulu ezinqubweni ze-petrochemical, imbangela evame kakhulu yokuvuza ayikona nje kuphela ukugqoka okungalingani kwendandatho eslayidayo, kodwa futhi ukuwohloka nokulimala kwe-O-ring.Ngemuva kokushintshela ku-HiPerSeal, izinkinga ezinjengokuthambisa irabha, ukuvuvukala, ukuqina kwendawo, nokugqoka kungathuthukiswa ngokuphelele, ngaleyo ndlela kuthuthukise kakhulu impilo yesevisi yezimpawu ze-shaft mechanical.

I-spring seal ifaneleka kokubili izinhlelo zokusebenza eziguquguqukayo nezimile.Ngaphezu kokufakwa uphawu ezindaweni ezishisa kakhulu ezishibhile ezishiwo ngenhla, ifaneleka kakhulu ukuvala izingxenye zomoya kanye namasilinda omfutho kawoyela ngenxa ye-coefficient yayo yokuhlanganisa izindebe ezivaliwe, ingcindezi yokuxhumana eqinile yokuvala, ukumelana nomfutho ophezulu, ukugijima kweradial okukhulu okuvumelekile. out, kanye nephutha likasayizi we-groove.Ingena esikhundleni sokuminyanisa okumise okuka-U noma oku-V ukuze kuzuzwe ukusebenza okuhle kakhulu kokuvala nempilo yesevisi.

Ukufakwa kwe-Spring Seal

I-Rotary spring seal kufanele ifakwe kuphela kuma-grooves avulekile.

Ukuze usebenzisane nokugxila kanye nokufakwa okungenangcindezi, landela lezi zinyathelo ezilandelayo:

1. Faka uphawu endaweni evulekile;

2. Faka isembozo ngaphandle kokusiqinisa kuqala;

3. Faka i-shaft;

4. Lungisa ikhava emzimbeni.

Isici se-spring seal kanje:

1. Ukusebenza kokuvala akuthintwa ukugcotshwa okunganele ngesikhathi sokuqalisa;

2. Yehlisa ngempumelelo ukuguga nokumelana nokungqubuzana;

3. Ngokuhlanganiswa kwezinto ezihlukene zokuvala kanye nemithombo, amandla okuvala ahlukene angaboniswa ukuhlangabezana nezidingo ezihlukahlukene zohlelo lokusebenza.Kusetshenziswa izindlela ezikhethekile zemishini ye-CNC, ngaphandle kwezindleko zesikhunta - ezifanele kakhulu inani elincane lezingxenye ezihlukahlukene zokuvala;

4. Ukumelana nokugqwala kwamakhemikhali nokumelana nokushisa kuphakeme kakhulu kunenjoloba yokuvala evame ukusetshenziswa, enobukhulu obuzinzile futhi akukho ukuwohloka kokusebenza kokuvala okubangelwa ukuvuvukala kwevolumu noma ukuncipha;

5. Isakhiwo esihle kakhulu, singafakwa kuma-O-ring grooves;

6. Ukuthuthukisa ngokuphawulekayo umthamo wokuvala kanye nempilo yesevisi;

7. I-groove ye-elementi yokuvala ingagcwaliswa nganoma iyiphi into evimbela ukungcola (njenge-silicone) - kodwa ayifanele indawo yemisebe;

8. Njengoba into yokuvala i-Teflon, ihlanzeke kakhulu futhi ayingcolisi inqubo.I-coefficient ye-friction iphansi kakhulu, futhi ngisho nasezinsizeni zejubane eliphansi kakhulu, ibushelelezi ngaphandle kwanoma yimuphi "umphumela we-hysteresis";

9. Ukumelana nokungqubuzana kokuqala okuphansi, okukwazi ukugcina ukusebenza kwamandla okuqala okuphansi ngisho noma umshini uvaliwe isikhathi eside noma usebenza ngezikhathi ezithile.

Ukusetshenziswa kweSpring Energized Seal

I-spring seal iyisici esikhethekile sokuvala esakhelwe izinhlelo zokusebenza ezinokugqwala kwezinga lokushisa eliphezulu, ukuthambisa okunzima, nokungqubuzana okuphansi.Inhlanganisela yezinto ezihlukene eziyinhlanganisela ye-Teflon, amapulasitiki obunjiniyela athuthukile, neziphethu zensimbi ezingagqwali zingahlangabezana ngokugcwele nezidingo ezikhulayo ezikhulayo zemboni.Izinhlelo zokusebenza ezijwayelekile zifaka:

1. Izigxivizo ze-axial zejoyinti elijikelezayo lengalo yokulayisha neyothulayo;

2. Izigxivizo zamavalvu okupenda noma ezinye izinhlelo zokudweba;

3. Izimpawu zamaphampu evacuum;

4. Isiphuzo, amanzi, imishini yokugcwalisa ubhiya (njengamavalvu okugcwalisa) nezigxivizo zemboni yokudla;

5. Izigxivizo zezimboni zezimoto nezasemkhathini, njengamagiya okuqondisa kagesi;

6. Izigxivizo zemishini yokulinganisa (ukungqubuzana okuphansi, impilo ende yesevisi);

7. Izigxivizo zeminye imishini yenqubo noma imikhumbi yokucindezela.

Vala umgomo njengokulandelayo:

I-PTFE plate spring inhlanganisela indandatho yokuvala emise okuka-U (ipulaki ye-pan plug seal) yakhiwa ngokusebenzisa ukushuba kwentwasahlobo okufanele kanye nokucindezela koketshezi lwesistimu ukusunduza udebe oluvalayo bese ucindezela ngobumnene endaweni yensimbi evalwayo, okwenza umphumela omuhle kakhulu wokuvala.

Imikhawulo yokusebenza:

Ingcindezi: 700kg/cm2

Izinga lokushisa: 200-300 ℃

Isivinini somugqa: 20m/s

Kusetshenziswa okuphakathi: uwoyela, amanzi, umusi, umoya, izinyibilikisi, izidakamizwa, ukudla, i-asidi ne-alkali, izixazululo zamakhemikhali.
