Babban Juriya na Lalata
Mahimman Features
Silicone nitride degassing rotor, tare da silicon nitride a matsayin ainihin kayan sa, yana haɗa ultra - high-tsarin ƙira da daidaitaccen tsarin sarrafawa, cimma nasarorin aiki a cikin aiwatar da sarrafa aluminum. Babban fasalinsa sune kamar haka:
I. Abubuwan Fa'idodi: Juriya na Zazzabi, Juriya na sawa, kuma Babu gurɓatawa
- Maɗaukaki Mafi Girma akan Graphite: Rotor da impeller an yi su da silicon nitride. Madaidaicin sarrafa shi da ƙarfinsa ya zarce na graphite, yana goyan bayan jujjuyawar ultra - high - gudun (har zuwa 8,000 rpm) kuma yana haɓaka rayuwar sabis.
- High - Temperatuur Resistance Oxidation: Babu kusan babu iskar shaka a cikin yanayin zafin jiki mai girma, gaba ɗaya guje wa matsalar "lalacewar aluminium narkakkar" da tabbatar da tsabtar samfur.
- Chemical Inertness: Ba ya amsa tare da narkakkar aluminum, stably rike da mafi kyau duka degassing sakamako na dogon lokaci. Babu buƙatar damuwa game da lalata kayan aiki yana shafar aiki.
II. Daidaitaccen Tsari: Tsayayyen Tsayi - Aiki Mai Saurin Gudun, Filayen Molten Flat
- Ultra - High Concentricity: Maƙarƙashiyar na'ura mai juyi ana sarrafa shi sosai a cikin 0.2 mm (inda 1 "siliki" = 0.01 mm). A yayin jujjuyawar sauri mai girma, girgizar ta yi ƙanƙanta sosai, tana kawar da jujjuyawar saman ruwa ta hanyar eccentricity.
- Daidaitaccen Tsarin Haɗin Kai: Shugaban rotor da igiya mai haɗawa an yi su ne da bakin karfe, tare da daidaitaccen aiki ya kai matakin 0.01 - mm. Haɗe tare da babban madaidaicin taro, an cimma “tuɓa mai girma mai sauri”, rage girman jujjuyawar saman narkakken aluminum da kuma tabbatar da kwanciyar hankali na samarwa.
III. Haɓaka Ayyuka: Ƙwarewa, Amincewa, da Rage Kuɗi
- Babban Maɗaukaki + Babban ƙarfi: Waɗannan kaddarorin guda biyu suna tabbatar da amincin tsarin kuma babu haɗarin nakasu yayin aiki mai ƙarfi - babban saurin aiki, yana sa shi daidaitawa zuwa matsanancin yanayin aiki.
- Fa'idodin Kwatancen Kwatancen: Idan aka kwatanta da rotors graphite, yana ɗaukar cikakken jagora a rayuwar sabis, juriyar gurɓatawa, da saurin daidaitawa. Yana rage yawan kulawar rufewa kuma a kaikaice yana inganta ingantaccen samarwa.

Yadda Ake Zaba The Degassing impeller?
Nau'in F Rotor Φ250×33
Saboda ƙira ta musamman na tsagi mai ƙarfi da haƙoran haƙoran waje, Nau'in F yana samar da ƙananan kumfa. Girman girmansa mafi girma yana haɓaka tarwatsewa a cikin narkakkar aluminum, yayin da mai siraran siraran yana rage girman juyi na narke.
Aikace-aikace: Dace da manyan lebur ingot da zagaye mashaya narkewa Lines (biyu - rotor ko sau uku - rotor degassing tsarin).
