Kodi ventilate ndi chubu chofiyira?

Chubu ng’anjo zimagwiritsa ntchito zatsopano ndi ang’onoang’ono mtanda kupanga mayunivesite, mabungwe kafukufuku, mafakitale ndi migodi mabizinezi, etc. Choncho kodi mukudziwa mmene mpweya ng’anjo chubu? Tiyeni titenge nitrogen monga chitsanzo kukuwonetsani momwe mungapititsire mpweya ku ng’anjo yamoto.

1. Lumikizani chubu la ng’anjo ya chubu ku dera la mpweya wa nayitrogeni, ndipo fufuzani kudontha kwake ndi madzi asopo pa mfundo iliyonse kuti mutsimikizire kuti palibe mpweya wotuluka.

2. Onetsetsani kuti mavavu a ng’anjo ya chubu ndi silinda ya nayitrogeni atsekedwa.

3. Tsegulani valavu yayikulu ya silinda ya nayitrogeni, ndiyeno tsegulani pang’onopang’ono chotsitsa chotsitsa kuti chitseko chikhale pa 0.1MPa.

4. Yatsani mphamvu ya mpope wamakina, tsegulani valavu yotulutsira ng’anjo ya chubu ndi ma valve awiri panjira ya mpweya wa mpope wamakina, ndikupopera kwa mphindi zisanu.

5. Tsekani ma valve awiri panjira ya mpweya wa mpope wamakina, kutseka valavu yotulutsira ng’anjo ya chubu, ndikuzimitsa mpope wamakina.

6. Tsegulani valavu yoyendetsera njira ya gasi yapamwamba ndipo pangani batani la batani kumalo “otseguka”.

7. Sinthani knob ya flowmeter kuti kuwerenga kukhale 20ml/min.

8. Tsegulani valavu yolowera mpweya ya ng’anjo ya chubu mpaka barometer iwerenge ziro.

9. Tsegulani valavu yolowera mu ng’anjo ya chubu, ndipo tsegulani valavu yotulukira panjira ya mpweya wa nayitrogeni.

10. Ng’anjo ya chubu ikhoza kutenthedwa pakatha mphindi 10 za mpweya wa nayitrogeni.
