Nzira yekupinza mhepo chubhu yevira?

Tube furnaces anonyanya kushandiswa mukuedza uye diki batch kugadzirwa mumayunivhesiti, tsvakurudzo masangano, maindasitiri uye mugodhi mabhizimisi, etc. Saka unoziva sei ventilate chubhu choto? Ngatitorei nitrogen semuenzaniso wekukuratidza nzira yekupfuudza gasi kune yakadzika chubhu choto.

1. Batanidza chubhu yechubhu yevira kudunhu renitrogen gasi, uye tarisa kudonhedza nemvura ine sipo pajoini rega rega kuti uone kuti hapana kubuda kwegasi.

2. Tarisa kuti mavharuvhu echubhu choto uye nitrogen cylinder akavharwa.

3. Vhura vharuvhu huru ye nitrogen cylinder, uye wobva wavhura zvishoma nezvishoma iyo yekubuda pressure yekudzikisa vharafu kuti ichengetedze yekubuda shinikizo pa 0.1MPa.

4. Batidza simba repombi yemagetsi, vhura vheji yekubuda yehuni yehuni uye mavharuvhu maviri ari munzira yegesi yepombi yemagetsi, uye pombi kwemaminitsi mashanu.

5. Vhara mavharuvhu maviri panzira yegesi yepombi yemagetsi, vhara vheji yekubuda yehuni yehuni, uye dzima pombi yemagetsi.

6. Vhura iyo yepamusoro gasi nzira yekudzora valve uye ita bhatani museve unongedze kune “yakavhurika” chinzvimbo.

7. Gadzirisa bhandi rekuyerera kuti riite kuverenga pa20ml/min.

8. Vhura iyo air inlet valve yechubhu choto kusvikira barometer yaverenga zero.

9. Vhura vharuvhu yekupinza yechubhu choto, uye vhura vharafu yekubuda panzira yenitrogen gasi.

10. Chivi chechubhu chinogona kupiswa chete mushure memaminitsi gumi enitrogen gasi.
