graphite rotor
1. Thegraphite rotoryana aiki ci gaba a cikin narke aluminum a kusan 750 ° C a gudun 200r / min ~ 400r / min, kuma ana buƙatar rayuwar sabis na gaba ɗaya don isa fiye da wata ɗaya.Thegraphite rotorna mu kamfanin an yi shi da high-tsarki graphite.Kyakkyawan graphite kanta yana da tasiri mai mahimmanci akan rayuwar sabis na rotor.A lokaci guda, ana amfani da murfin kariya na anti-oxidation akan saman, kuma ana iya ƙara rayuwar sabis zuwa kwanaki 50-60.
2. Ƙa'idar aiki na rotor graphite:
Rotor graphite ya ƙunshi sandar rotor da bututun ƙarfe.Tsarin watsawa yana motsa na'urar graphite don juyawa, kuma argon ko nitrogen ana hura su cikin narkewar aluminum ta sandar rotor da bututun ƙarfe.Rotor mai jujjuyawa mai saurin sauri yana karya argon ko iskar nitrogen da ke shiga cikin narkewar aluminium don samar da ƙananan kumfa da yawa, waɗanda ke tarwatsa su a cikin narkakken ƙarfe.Lokacin da kumfa suna cikin hulɗa, kumfa a cikin narke yana dogara ne akan bambancin matsa lamba na gas da kuma ka'idar adsorption na saman don sha hydrogen a cikin narkewa, adsorb oxidized slag, kuma a fitar da shi daga narkewar yayin da kumfa ya tashi don tsarkakewa. narke.
Amfani da kula da rotor graphite:
- An yi bututun ƙarfe mai jujjuya da graphite mai tsafta.Baya ga yin la’akari da tsarin bututun ƙarfe don karya kumfa mai iska, yana kuma amfani da ƙarfin centrifugal da aka samar ta hanyar motsa alluran narke don sanya narkewar ya shiga cikin bututun ƙarfe kuma ya haɗu da iskar da aka fitar a kwance don samar da iskar gas.or an fitar da ruwa mai gudana don ƙara yawan wurin sadarwa da lokacin hulɗa tsakanin kumfa da ruwa na aluminum gami, da kuma inganta haɓakawa da tsaftacewa.
2. Bukatar rayuwar sabis gabaɗaya ya fi wata ɗaya.Dorewa shine sau 3-4 mafi kyau fiye da na rotor mara-oxidizing.Yana iya wucewa har zuwa kwanaki 55-65 a kimanin 700 ° C, kuma zai iya wucewa har zuwa kwanaki 25-35 a yanayin zafi sama da 1000 ° C.Tare da murfin kariya na anti-oxidation a saman, ana iya ƙara rayuwar sabis zuwa kwanaki 50-60.
3.Kafin nutsar da rotor graphite a cikin ruwa na aluminum, preheat shi na mintuna 5 zuwa mintuna 10 a kusan 100 mm sama da saman ruwa don guje wa tasirin saurin sanyaya akan kayan;kafin a nutsar da rotor a cikin ruwa, gas dole ne a wuce ta hanyar; Ana iya dakatar da samar da iska kawai bayan da rotor ya tashi daga matakin ruwa, don hana ramin iska na bututun rotor daga toshewa.
4. Babban dalilin graphite na'ura mai juyi lalacewa ne high-zazzabi hadawan abu da iskar shaka: babban bangaren graphite ne carbon, da kuma graphite za a iya bayyane oxidized a karkashin iska yanayi wuce 600 ° C. A kayayyakin na carbon hadawan abu da iskar shaka halayen ne CO da CO2 gas, wanda ba zai iya kare rotor ba.Gabaɗaya magana, akwatin keɓaɓɓen ba za a iya rufe shi gaba ɗaya ba, kuma yawancin rami na cikin akwatin ba a cika shi da iskar gas mai kariya ba, don haka iskar shaka na rotor graphite ba makawa.A sakamakon iskar oxygen da ta yi, diamita na ramin rotor yana raguwa a hankali har sai ya karye kuma an goge shi.
