Analysis on Automatic Control of Furnace Temperature in High Temperature Muffle Furnace

Kuongorora kwe otomatiki kudzora tembiricha yakakwira muffle tembiricha, iko kukanganisa kwekushisa kwakanyanya muffle tembiricha kusvika kune yakapihwa tembiricha, kudzima kana kudzima moto unopisa unopihwa muchoto chekupikisa, kana kuramba uchichinja saizi yekupisa sosi simba kuti ita kuti kupisa kwechoto kugadzikane uye kunopa mubayiro Seta tembiricha yemhando yekusangana nezvinodiwa zvekupisa kurapwa. Kune maviri-chinzvimbo, matatu-chinzvimbo, mugove, mugove wakakosha uye mugove wakakosha kubva kune zvichingodaro. Resistance furnace tembiricha yekudzora ndiyo yakadaro reverberant kugadzirisa maitiro. Kuenzanisa theoretical tembiricha yevira uye inodiwa yakakwirira tembiricha tembiricha yevira, iko kukanganisa kunowanikwa. Chiratidzo chekutonga chinowanikwa mushure mekunge kukanganisa kwabatwa kugadzirisa simba rekupisa kwevira rekupikisa, uye ipapo kutonga kwekushisa kwechoto kunopedzwa. 1) Iyo yekudzora maitiro (PID control) inogadzirwa zvinoenderana neiyo yekukanganisa share, yakabatanidzwa uye inobuda, inova ndiyo yakajairika nzira yekudzora inoshandiswa mukugadzirisa maitiro. 2) Maviri-chinzvimbo mamiriro-Inongoda kuvhurika uye kuvharwa. Kana kutonhora kwechoto chepamusoro-soro kwakadzika kudarika kukosha kwakapiwa, actuator yakazaruka zvakakwana; kana tembiricha yevira yakakwira kupfuura kukosha kwakapihwa, iyo actuator yakavharwa zvizere. The actuator kazhinji contactor. 3) Matatu-chinzvimbo mamiriro-Iyo ine mbiri yakapihwa kukosha kwepamusoro uye yakaderera miganhu. Kana kutonhora kwechoto chepamusoro-soro kwakadzika kudarika kupiwa kukosha kwemuganhu wakaderera, iyo contactor yakazaruka zvakakwana; apo tembiricha yechoto iri pakati pepamusoro nepamusoro yakapihwa kukosha, iyo actuator Yakazaruka zvishoma; apo kutonhora kwechoto chepamusoro-soro kunodarika muganhu wepamusoro wekugadzirisa kukosha, actuator yakavharwa zvakakwana. Semuenzaniso, kana iyo tubular heater iri chinhu chekudziya, matatu-nzvimbo yekumisikidza inogona kushandiswa kupedzisa mutsauko mukupisa uye simba rekuchengetedza kupisa.
