Laboratory Kutentha chofunda kukula konse

Laboratory Chemical Equipment 450 Digital DigitalKutentha Mantle

Zogwiritsa:

Amagwiritsidwa ntchito kwambiri pakuwotcha madzi m'ma laboratories a makoleji ndi mayunivesite, mafuta opangira mafuta ndi mankhwala, mankhwala, kuteteza chilengedwe etc.

Makhalidwe:

1. Chipolopolocho chimatengera mbale yoziziritsa yozizira yokhala ndi pamwamba.
2. Pakatikati pakatikati amatengera kutentha kwambiri kwa alkali fiberglass ngati chotchingira, waya wa nickel-chromium resistance amamata mu insulating layer ndi kuluka.
3. ili ndi makhalidwe oyendetsera kutentha kwamagetsi, malo otentha otentha, kutentha kukwera mofulumira, kusunga mphamvu ya kutentha, kutentha kofanana.
4. Zosaonongeka, zosakalamba, zolimba komanso zolimba, zotetezeka komanso zodalirika.Ili ndi mawonekedwe angwiro komanso zotsatira zabwino.Ndi yosavuta kugwira ntchito.

Malangizo ogwiritsira ntchito ndi machenjezo:
1.Zovala zotentha zimakhala ndi mitundu iwiri: DZTW mtundu (Electronic control) ndi mtundu wa SXKW (digital control).
2 Monga galasi CHIKWANGWANI TACHIMATA ndi mafuta pamene kupanga, ntchito pa nthawi yoyamba,
Kutentha pang'onopang'ono. Onani utsi woyera, ndiye kudula mphamvu.Utsi ukatha, tenthetsaninso. bwerezaninso izi kwa osasuta musanagwiritse ntchito bwino.Mtundu wa SXKW uyenera kusinthidwa kukhala 60-70 ℃ pochotsa utsi.sensa yolumikizidwa ndi chipolopolo, ndikuyika sensor mu chofunda chotenthetsera.Yatsani mphamvu .loleni lokha lichotse utsi.
3. DZTW mtundu, ali akalumikidzidwa awiri ozungulira ndi lalikulu, mankhwalawa amalamulidwa ndi zigawo zamagetsi, kudzera potentiometer wotchi, kusintha voteji kulamulira kutentha, nthawi yoyamba ntchito, musati kusintha voteji kwambiri, ayenera kukhala wodekha. kutentha, apo ayi n'zosavuta kuti chotenthetsera chiwonongeke.
4.XKW mtundu, mankhwala amagwiritsa patsogolo digito kulamulira dera, kachipangizo anaika mwachindunji mwa madzi Kutentha, kulamulira kutentha kudzera mu kuzindikira.
(1) mukamagwiritsa ntchito, molingana ndi malangizo omwe ali pamwambapa kuti muchotse utsi, zimitsani mphamvu, sinthani choyimbira, chokhazikika pa kutentha komwe mukufuna, ikani sensa mumadzimadzi.Yatsani mphamvu.kuwala kobiriwira kumasonyeza kutentha.kuwala kofiira kumasonyeza kuyimitsa kutentha, kuwongolera kutentha kulondola: ± 3-5 ℃.
(2) sensa ndiye zigawo zazikulu zowongolera kutentha kwa kutentha, pamwamba pakatikati pakatikati payenera kulumikizidwa ndi pamwamba pa chubu cha sensor.ndipo iyenera kuyikidwa mumadzi kuti itenthedwe.popanda kutero zidzakhudza mwachindunji kulondola kwa mita ya digito.
3) Ponena za mphamvu ya mphamvu, kutentha kumatha kukhala ndi chodabwitsa kwambiri, kotero mukamagwiritsa ntchito, ikani kutentha kukhala 80% ya kutentha komwe mukufuna, mukafika kutentha, ndikuyika kutentha komwe mukufuna, izi zidzachepetsa kutentha. overshoot chodabwitsa.
(4) 'RST' knob ndiye konikoni bwino kwa chipangizo cholakwika cha kutentha.Kutembenukira kumanzere ndi '-'. Tembenukira kumanja ndi '+'.Ngati kutentha kuli pansi pa seti
