LEAT-4 Thermal Conductivity Measurement Apparatus

Tlhaloso e Khutšoanyane:

Ho na le mekhoa e 'meli ea ho lekanya mocheso oa mocheso- mokhoa o tsitsitseng le mokhoa o matla, sesebelisoa sena ke mofuta oa mokhoa o tsitsitseng.
Ka mokhoa o tsitsitseng oa boemo, re futhumatsa sampuli pele, 'me phapang ea mocheso ka hare ho sampuli e etsa hore mocheso o fetisetsoe ho tloha mocheso o phahameng ho ea ho o tlaase,' me mocheso oa ntlha e 'ngoe le e' ngoe ka har'a sampuli o tla fetoha ka lebelo la ho futhumatsa le lebelo la ho fetisa mocheso. ;ha maemo a liteko le litekanyetso li laoloa ka mokhoa o nepahetseng ho etsa hore mokhoa oa ho futhumatsa le ho fetisa mocheso o fihle boemong bo leka-lekaneng, kabo e tsitsitseng ea mocheso e ka thehoa ka har'a sampuli The conductivity ea mocheso e ka baloa ho tloha kabong ea mocheso.

Lintlha tsa Sehlahisoa

Li-tag tsa Sehlahisoa

Lintlha tse ka sehloohong tsa tekheniki:
1. E amohela mocheso o ka thōko oa motlakase o tlaase, o sireletsehileng le o loketseng ho o sebelisa;
2. Ho sebelisa thermocouple e tloaelehileng ea naha ho lekanya mocheso le Teflon flexible protection tube, thermocouple ha e bonolo ho senya;
3. Matla a thermoelectric a lekanyetsoa ka khanyetso e phahameng ea ka hare, ho nepahala ho phahameng, amplifier e tlaase ea drift le voltmeter ea digital e meraro le halofo;
4. Ho futhumatsa mocheso oa PID ho sebelisoa ho tsitsisa mocheso oa poleiti ea koporo e futhumatsang le ho ntlafatsa ho nepahala ha teko.

Lintlha tse ka sehloohong tsa tekheniki:
1. Digital voltmeter: pontšo ea 3.5 bit, sebaka sa 0 ~ 20mV, ho nepahala ha tekanyo: 0.1% + mantsoe a 2;
2. Stopwatch ea Digital: Stopwatch ea linomoro tse 5 e nang le qeto e fokolang ea 0.01s;
3. Mofuta oa taolo ea mocheso oa taolo ea mocheso: mocheso oa kamore ~ 120 ℃;
4. Matla a ho futhumatsa: ac36v e phahameng, qetellong ea ac25v, matla a futhumatsang a ka bang 100W;
5. Mocheso oa koporo poleiti: radius 65mm, botenya 7mm, boima 810g;
6. Lisebelisoa tsa teko: duralumin, rabara ea silicone, boto ea rabara, moea, joalo-joalo.
7. Potoloho ea matšeliso ea ntlha ea leqhoa ea thermocouple e ka ekeletsoa ho boloka bothata ba ho sebelisa motsoako oa metsi a leqhoa;
8. Li-sensor tse ling tsa mocheso li ka sebelisoa ho lekanya mocheso, joalo ka PT100, AD590, joalo-joalo.
