Kusamala pa unsembe wa muffle ng’anjo

Ng’anjo ya muffle imakhala ndi mawonekedwe a liwiro lachangu kutentha, mphamvu yabwino yotchinjiriza, chitetezo chachikulu, chitetezo ndi kudalirika. Amagwiritsidwa ntchito kwambiri popanga matenthedwe ang’onoang’ono ogwira ntchito, komanso kuyendera ndi kusanthula. Zinthu zabwino zitha kugwiritsidwa ntchito kwambiri, koma zabwino sizingasiyanitsidwe ndikuchita bwino komanso kotetezeka. Tikukutengerani kuti mumvetsetse zodzitetezera pakukhazikitsa, motere:

1. Mukatsegula phukusili, fufuzani ngati ng’anjo ya muffle ili bwino komanso ngati zowonjezerazo zatha.

2. Ambiri muffle ng’anjo safuna unsembe wapadera. Zimangofunika kuyikidwa pansi pa tebulo lolimba la simenti kapena shelefu m’nyumba, ndipo pasakhale zinthu zoyaka ndi kuphulika kuzungulira. Wowongolera ayenera kupewa kugwedezeka, ndipo malowo asakhale pafupi kwambiri ndi ng’anjo yamagetsi kuti ateteze zigawo zamkati kuti zisagwire bwino ntchito chifukwa cha kutentha kwambiri.

3. Ikani thermocouple mu ng’anjo ya 20-50mm, ndipo lembani kusiyana pakati pa dzenje ndi thermocouple ndi chingwe cha asibesitosi. Lumikizani thermocouple ku waya wolipirira wowongolera (kapena gwiritsani ntchito waya wotsekereza chitsulo), tcherani khutu kumitengo yabwino ndi yoyipa, ndipo musawalumikize mobwerera.

4. Chophimba chamagetsi chiyenera kuikidwa pa chingwe chotsogolera kuti chiwongolere mphamvu yaikulu. Kuti zitsimikizire kuti zikugwira ntchito bwino, ng’anjo ya muffle ndi wowongolera ayenera kukhazikitsidwa modalirika.

5. Musanagwiritse ntchito, sinthani thermostat mpaka zero point. Mukamagwiritsa ntchito waya wamalipiro ndi compensator yozizira, sinthani zero point pa makina opangira kutentha kwa compensator yozizira. Pamene waya wamalipiro sagwiritsidwa ntchito, makina a zero amasinthidwa. Kufika pa sikelo ya ziro, koma kutentha komwe kukuwonetsedwa ndi kusiyana kwa kutentha pakati pa malo oyezera ndi malo ozizira a thermocouple.

6. Sinthani kutentha kwa seti ku kutentha komwe kumafunikira, ndiyeno kuyatsa mphamvu. Yatsani ntchito, ng’anjo ya muffle imapatsidwa mphamvu, ndipo zowonjezera zamakono, magetsi, mphamvu zotulutsa ndi kutentha kwa nthawi yeniyeni zikuwonetsedwa pa gulu lolamulira. Pamene kutentha kwa mkati mwa ng’anjo yamagetsi kumawonjezeka, kutentha kwa nthawi yeniyeni kudzawonjezekanso. Chodabwitsa ichi chikuwonetsa kuti dongosololi likugwira ntchito bwino.
