U ka khetha heater e nepahetseng ea duct air?

Hobane heater ea moea e sebelisoa haholo indastering. Ho ea ka litlhoko tsa mocheso, litlhoko tsa bophahamo ba moea, boholo, thepa le tse ling, khetho ea ho qetela e tla fapana, 'me theko e tla boela e fapane. Ka kakaretso, khetho e ka etsoa ho latela lintlha tse peli tse latelang:

1. Mohloli:

Khetho e nepahetseng ea metsi e ka kopana le matla a hlokahalang ka mocheso oa mocheso, ho etsa bonnete ba hore heater e ka fihla mocheso o hlokahalang ha o sebetsa. Joale, tLintlha tse latelang li lokela ho nahanoa mabapi le khetho ea lipalo tsa metsi:

(1) Chesa mochini o futhumatsang ho tloha mochesong oa pele ho beha mocheso ka nako e behiloeng;

(2) tlas'a maemo a ho sebetsa, matla a lokela ho lekana ho boloka mocheso oa mocheso;

(3) Ho lokela ho ba le moeli o itseng o sireletsehileng, ka kakaretso e lokela ho ba 120%.

Ho hlakile hore metsi a maholoanyane a khethoa ho tloha ho (1) le (2), 'me joale, metsi a khethiloeng a atolosoa ke moeli o sireletsehileng.

2. Boleng ba moralo oalebelo la moya:

Tekanyo ea khatello ea moea, lebelo la moea le bophahamo ba moea li ka finyelloa ka pitot tube, manometer ea mofuta oa U, micro-manometer e tilting, anemometer ea bolo e chesang le lisebelisoa tse ling. Pitot tube le U-mofuta oa manometer li ka leka khatello e felletseng, khatello e matla le khatello e tsitsitseng ka har'a heater ea duct ea moea, mme boemo ba ho sebetsa ba sefutho le ho hanyetsa ha sistimi ea moea ho ka tsejoa ka khatello e felletseng e lekantsoeng. Molumo oa moea o ka fetoloa ho tloha khatellong e matla e lekantsoeng. Hape re ka lekanya lebelo la moea ka anemometer ea bolo e chesang, ebe re fumana molumo oa moea o tsamaellanang le lebelo la moea.

1. Hokela fene le phaephe ea moea;

2. Sebelisa tepi ea tšepe ho lekanya boholo ba kotopo ea moea;

3. ho ea ka bophara kapa boholo ba likotopo tse khutlonnetsepa, fumana sebaka sa sebaka sa ho lekanya;

4. Bula lesoba le chitja (φ12mm) holim'a duct ea moea sebakeng sa teko;

5. Tšoaea sebaka sa lintlha tsa ho lekanya holim'a pitot tube kapa anemometer ea bolo e chesang;

6. Kopanya tube ea picot le manometer ea U-type ka tube ea latex;

7. Pitot tube kapa hot ball anemometer e kenngoa ka ho toba ka har'a sekoti sa moea sekoti sa ho lekanya, e le ho etsa bonnete ba hore boemo ba ntlha ea ho lekanya bo nepahetse, 'me u ele hloko tataiso ea pitot tube probe;

8. Bala khatello e feletseng, khatello e matla le khatello e tsitsitseng ka har'a duct ka ho toba ka manometer ea U-shaped, 'me u bale lebelo la moea ka har'a duct ka ho toba ho anemometer ea bolo e chesang.
