Chisindikizo cha Spring/Spring Energized Seal/Variseal ndi chinthu chosindikizira chapamwamba chokhala ndi U-shape Teflon mkati mwa masika apadera.Pogwiritsa ntchito mphamvu yoyenera ya masika ndi kuthamanga kwamadzimadzi, milomo yosindikiza (nkhope) imakankhidwa kunja ndikukanikizidwa pang'onopang'ono pazitsulo zomwe zimasindikizidwa kuti zisindikize bwino kwambiri.Kuthamanga kwa kasupe kumatha kuthana ndi kupendekera pang'ono kwa zitsulo zokwerera pamwamba ndi kuvala kwa milomo yosindikiza, ndikusunga kusindikiza komwe kumayembekezeredwa.
Teflon (PTFE) ndi chinthu chosindikizira chokhala ndi mphamvu zapamwamba zolimbana ndi mankhwala komanso kutentha kwabwino poyerekeza ndi rabara ya perfluorocarbon.Itha kugwiritsidwa ntchito pamadzi ambiri amadzimadzi, zosungunulira, komanso ma hydraulic ndi mafuta opaka mafuta.Mphamvu yake yotupa yotsika imalola kusindikiza kwa nthawi yayitali.Akasupe osiyanasiyana apadera amagwiritsidwa ntchito kuthana ndi zovuta zotanuka za PTFE kapena mapulasitiki ochita mphira apamwamba kwambiri, Zisindikizo Zopangidwa zomwe zimatha kulowa m'malo ambiri ogwiritsira ntchito osasunthika kapena osunthika (kubwereza kapena kusuntha), ndi kutentha kuchokera pafiriji mpaka 300 ℃. , ndi kuthamanga kumachokera ku vacuum kupita ku ultra-high pressure ya 700kg, ndi kuthamanga kwa 20m / s.Akasupe angagwiritsidwe ntchito pamadzi osiyanasiyana owononga kutentha kwambiri posankha zitsulo zosapanga dzimbiri, Elgiloy Hastelloy, etc. malinga ndi malo osiyanasiyana ogwiritsira ntchito.
Chisindikizo cha masikazitha kupangidwa molingana ndi muyezo wa AS568AO-ringgroove (monga radial shaft seal,piston chizindikiro, axial face seal, etc.), m'malo mwa O-ring ya chilengedwe chonse.Chifukwa cha kusowa kwa kutupa, imatha kusunga ntchito yabwino yosindikiza kwa nthawi yayitali.Mwachitsanzo, zosindikizira za shaft zamakina zomwe zimagwiritsidwa ntchito m'malo otentha kwambiri pazigawo za petrochemical, chomwe chimayambitsa kutayikira sikungokhala kuvala kosagwirizana kwa mphete yolowera, komanso kuwonongeka ndi kuwonongeka kwa mphete ya O.Pambuyo posinthira ku HiPerSeal, mavuto monga kufewetsa mphira, kutupa, kuyanika pamwamba, ndi kuvala amatha kusintha kwambiri, motero amasintha kwambiri moyo wautumiki wa zisindikizo zamakina.
Chisindikizo cha masika ndi choyenera kwa ntchito zonse zosinthika komanso zosasunthika.Kuphatikiza pa ntchito zosindikizira m'malo owononga kwambiri omwe atchulidwa pamwambapa, ndi abwino kwambiri kusindikiza zigawo za mpweya ndi mafuta osindikizira chifukwa cha kutsika kwake kwa milomo yotsekemera, kutsekemera kokhazikika, kuthamanga kwapamwamba, kuthamanga kwakukulu kovomerezeka. kunja, ndi vuto la kukula kwa groove.Imalowa m'malo mwa kukakamiza kooneka ngati U kapena V kuti mukwaniritse ntchito yabwino yosindikiza komanso moyo wautumiki.
Kuyika kwa Spring Seal
Chisindikizo cha rotary spring chiyenera kuikidwa m'mizere yotseguka.
Kuti mugwirizane ndi concentricity ndi kuyika kopanda kupsinjika, tsatirani izi:
1. Ikani chisindikizo mu polowera lotseguka;
2. Ikani chivundikirocho osachilimbitsa poyamba;
3. Ikani shaft;
4. Konzani chophimba pathupi.
Makhalidwe a spring seal ndi awa:
1. Ntchito yosindikiza simakhudzidwa ndi mafuta osakwanira panthawi yoyambira;
2. Kuchepetsa bwino kuvala ndi kukaniza kukangana;
3. Kupyolera mu kuphatikiza kwa zipangizo zosiyana zosindikizira ndi akasupe, mphamvu zosiyana zosindikizira zimatha kuwonetsedwa kuti zikwaniritse zosowa zosiyanasiyana zogwiritsira ntchito.Makina apadera opangira makina a CNC amagwiritsidwa ntchito, popanda mtengo wa nkhungu - makamaka oyenera kumagulu ochepa osindikizira osiyanasiyana;
4. Kukana kwa dzimbiri kwa mankhwala ndi kukana kutentha ndipamwamba kwambiri kuposa mphira wosindikizira omwe amagwiritsidwa ntchito kawirikawiri, ndi miyeso yokhazikika ndipo palibe kuwonongeka kwa ntchito yosindikiza chifukwa cha kutupa kwa voliyumu kapena kuchepa;
5. Mapangidwe okongola, akhoza kuikidwa muzitsulo za O-ring grooves;
6. Kupititsa patsogolo kwambiri kusindikiza mphamvu ndi moyo wautumiki;
7. Mtsinje wa chinthu chosindikizira ukhoza kudzazidwa ndi zinthu zilizonse zotsutsana ndi kuipitsa (monga silicone) - koma sizoyenera malo opangira ma radiation;
8. Monga zinthu zosindikizira ndi Teflon, ndizoyera kwambiri ndipo siziipitsa ndondomekoyi.Mkangano wa coefficient ndi wotsika kwambiri, ndipo ngakhale pama liwiro otsika kwambiri, umakhala wosalala popanda "hysteresis effect";
9. Kutsika kwamphamvu koyambira koyambira, kumatha kukhalabe ndi mphamvu zochepa zoyambira ngakhale makinawo atatsekedwa kwa nthawi yayitali kapena akugwira ntchito pafupipafupi.
Kugwiritsa Ntchito Spring Energized Seal
Chisindikizo cha masika ndi chinthu chosindikizira chapadera chomwe chimapangidwira kuti chizigwiritsidwa ntchito ndi dzimbiri kutentha kwambiri, mafuta ovuta, komanso kukangana kochepa.Kuphatikizika kwa zida zamitundu yosiyanasiyana ya Teflon, mapulasitiki apamwamba aukadaulo, ndi akasupe azitsulo osachita dzimbiri amatha kukwaniritsa zosowa zamakampani zomwe zikuchulukirachulukira.Zomwe zimagwiritsidwa ntchito ndizo:
1. Zisindikizo za Axial za mgwirizano wozungulira wa mkono wonyamula ndi kutsitsa;
2. Zisindikizo za ma valve opaka utoto kapena njira zina zopenta;
3. Zisindikizo za mapampu vacuum;
4. Chakumwa, madzi, zida zodzaza mowa (monga ma valve odzaza) ndi zisindikizo zamakampani azakudya;
5. Zisindikizo zamafakitale agalimoto ndi zakuthambo, monga zida zowongolera mphamvu;
6. Zisindikizo za zida zoyezera (kukangana kochepa, moyo wautali wautumiki);
7. Zisindikizo za zida zina zogwirira ntchito kapena zotengera zokakamiza.
Lembani mfundo motere:
PTFE mbale kasupe kuphatikiza U-zoboola pakati kusindikiza mphete (poto pulagi chisindikizo) amapangidwa pogwiritsa ntchito koyenera kasupe kukanikiza ndi dongosolo madzimadzi kuthamanga kukankhira kunja mlomo wosindikiza ndi modekha kukanikiza zitsulo pamwamba osindikizidwa, kupanga kwambiri kusindikiza zotsatira.
