Mathermocouple ekupisa kwakanyanya
Tsananguro yeChigadzirwa
Mathermocouple ane sheathed (anozivikanwawo se mineral-insulated thermocouples) inyanzvi dzekupisa dzemaindasitiri dzinoshanda zvakanyanya dzakagadzirirwa kushandiswa kwakaoma.Mhando huru dzinosanganisira K, N, E, J, T, uye S, inokwanisa kuyera tembiricha kubva pa -200°C kusvika 1300°C yemvura, utsi, magasi, uye nzvimbo dzakasimba.
Mathermocouple ane sheathed anoshandiswa zvakanyanya mumaindasitiri akadai sepetroleum, makemikari, kugadzira magetsi, simbi, uye ndege.
Thermocouple ine sheath inyanzvi yekupisa inogadzirwa kuburikidza nemaitiro ekumanikidzana kwemechanical, inobatanidza waya dzethermocouple, zvinhu zvinodzivirira kupisa, uye sheath yesimbi. Ine kuchinjika, inodzivirira kupisa kwakanyanya, uye inoshivirira kumanikidzwa kwakanyanya. Kana ichienzaniswa nethermocouples dzemazuva ano, mhando yesheath ine dhayamita diki uye inokombama zvakanyanya, zvichiita kuti ive yakakodzera kuyerwa kupisa munzvimbo dzakamanikana, dzakaoma kusvika, ukuwo ichipa mhinduro nekukurumidza.
Nheyo yekushanda yeSheathed Thermocouples
Pfungwa yekuyera tembiricha ye sheathed thermocouple yakafanana neye standard thermocouple, zvichibva paSeebeck effect. Kana paine musiyano wetembiricha pakati pe measuring junction (hot end) ne reference junction (cold end/connection end), thermal electromotive force (EMF) inogadzirwa mu circuit yakagadzirwa nema conductor maviri akasiyana. Nekuyera iyi thermal EMF, tembiricha iri pa measuring junction inogona kuonekwa.
Zvimiro zveSheathed Thermocouples
• Nguva yekukurumidza yemhinduro yekupisa uye kukanganisa kwakaderera kwesimba
• Simba guru remakanika, rinodzivirira kumanikidzwa, kuroverwa, uye kudedera
• Kuiswa kwacho kunochinjika nekuda kwekugona kukotama
• Haipindi kupisa kwakanyanya uye ngura
Mashandisirwo eSheathed Thermocouples
• Kudzora maitiro emaindasitiri:Kutarisa nekudzora tembiricha mumapaipi, ma reactor, nemimwe michina muindasitiri yepetroleum, makemikari, uye magetsi.
• Mashandisirwo ekupisa kwakanyanya uye simbi:Kuyerwa kwekupisa mumidziyo inodziya zvakanyanya senge maovheni nemaovheni ekupisa mumaindasitiri esimbi nesimende.
• Nzvimbo dzakakosha:Kuyerwa kwekupisa kwemhinduro inokurumidza kana nzvimbo yakamanikana mukuyedza injini dzemuchadenga uye kuyedza kwesainzi.
• Mamiriro ezvinhu akaomarara:Nzvimbo dzakaoma dzekushanda dzinosanganisira kudedera, kumanikidzwa kwakanyanya, zvinodiwa kuti uise zvakakombama, kana kuti unoda kukurumidza kupindura.
Mhando dzeThermocouple Measuring Junction
Rudzi rwakagayiwa:Nzvimbo yekuyera yakasungirirwa padanda, zvichiita kuti pave nekukasira kupindura. Zvisinei, haina kukodzera nzvimbo dzinofambisa mvura kana dzinoparadza.
Rudzi rusina madziro:Nzvimbo yekuyera inodzivirirwa nemagetsi kubva muchikamu chesimbi. Inopa mhinduro inononoka zvishoma asi ine simba rekudzivirira ruzha, ndiyo inonyanya kushandiswa, uye inogara kwenguva refu.
Rudzi rwakaratidzwa:Nzvimbo yekuyera inoonekwa kunze kweshedhi, zvichiita kuti pave nekukasira kukuru. Zvisinei, waya idzi dzinogona kukuvara, zvichiita kuti dzisashandiswe zvakanyanya pamidziyo yakaoma isingaparadzi.
