Matambudziko anofanirwa kutariswa panguva yekuenzanisa kwese kweiyo muffle furnace system

(1) Kuiswa uye wiring ye standard thermocouple vira dzinoitwa kana choto chekudzivirira chadzimwa. Mushure mekunge wiring ichitariswa, moto wekupikisa unogona kuvhurwa kuti uwedzere kutonhora.

(2) Mugumo wekuyera weiyo thermocouple yakajairwa inofanira kuiswa padyo nenzvimbo yekuongorora sampuli, asi sampuli kana madziro emukati echoto haafanire kubatwa kudzivirira kusvibiswa kana kukuvadzwa kune yakajairwa thermocouple.

(3) Mushure mekunge tembiricha yasvika padanho rekudzora tembiricha, kuitira kuti tembiricha yevira ive yunifomu uye yakagadzikana, zvinodikanwa kudzora tembiricha kwemaminitsi makumi matatu usati waverenga. Sezvo iyo yechipiri mita yevira yekupikisa isina kuwiriraniswa neiyo millivolt mita kuratidza, iyo yepamusoro uye yakaderera kukosha yemamita yemillivolt inofanirwa kuverengerwa kutenderera kwega kwekuverenga, uye yakakwirira uye yakaderera kukosha inoratidzwa neyechipiri mita. inofanira kuverengwa saizvozvo.

(4) The measurement of furnace temperature uniformity must be carried out when it reaches a thermally stable state under no-load conditions. For resistance furnaces with fans, the fans must work normally during the measurement.

(5) Kana chiratidzo chikanganiso chakakurisa, tarisa kana choto chiri kushanda nemazvo. Semuyenzaniso, kuitira kudzivirira simbi isina simbi yekudzivirira chubhu ye thermocouple yechidzitiro chekudzora kubva pakupfupikiswa kuenda kuwaya yechoto, insulating porcelain chubhu inoiswa pane thermocouple yechishandiso chekudzora. Nenzira iyi, iyo insulating porcelain chubhu inofanirwa kupfupikiswa kudzivirira kureba chaiko kweiyo thermocouple yechishandiso chekudzora kuburitswa. Ipfupi pane 8-10 nguva dze thermocouple kudzivirira chubhu; gomba remudziyo wekutonga thermocouple pamadziro echoto rinofanira kuvharwa zvakasimba kudzivirira kurasikirwa kwekupisa munzvimbo iri pedyo. Mumamiriro ezvinhu chaiwo, mamwe matanho anogona kutorwa kudzikisa kukosha kwekugadziriswa kwemunda wechoto nehukuru hwakakura hwechikanganiso chechiratidzo.

(6) Mushure mekugadzirisa, kuitira kuti urege kukuvadza thermocouple kana kupfupisa hupenyu hwe thermocouple, chiyero che thermocouple hachigoni kubviswa nokukurumidza, uye gonhi revira harigoni kuvhurwa nokukurumidza nokuti kukurumidza kupisa uye kutonhora kuchakuvadza choto.
