Njira zopewera kusungirako ndi kugwiritsa ntchito mpweya wamankhwala wamankhwala ndi chiyani?

Njira zopewera kusungirako ndi kugwiritsa ntchito oxygen yachipatala ndi chiyani?

Mpweya wamankhwala ndi mankhwala owopsa, ogwira ntchito yazaumoyo ayenera kulimbikitsa kupewa ndi kuwongolera zoopsa zachitetezo, kusungitsa okosijeni wamankhwala ndikugwiritsa ntchito kasamalidwe ka chitetezo, kupewa ngozi zachitetezo.

I.  Kuwunika zoopsa

Oxygen imakhala yoyaka kwambiri, kukhudzana kwake ndi mafuta ndi ufa wina wa organic, kutentha thupi kumayambitsa kuyaka ndi kuphulika, ndipo kukhudzana ndi lawi lotseguka kapena kuyatsa kwa zinthu zoyaka kudzakulitsa kukula kwa kutulutsa.

Valavu ya silinda ya okosijeni ngati palibe chitetezo cha kapu, kugwedezeka kugwedezeka kapena kugwiritsa ntchito molakwika, kusasindikiza bwino, kutayikira, kapena kuwonongeka kwa ma valve, kungayambitse kuthamanga kwa mpweya chifukwa cha kuphulika kwathupi.

II. Malangizo a Chitetezo

Ma cylinders okosijeni posungira, kusamalira, kugwiritsa ntchito, ndi zina zimayang'ana pa zinthu zotsatirazi.

(A)  Kusungirako

1. Masilinda a oxygen opanda kanthu ndi masilinda olimba ayenera kusungidwa padera, ndikuyika zizindikiro zomveka bwino.Simungathe ndi acetylene ndi zina zoyaka moto masilindala ndi zinthu zina kuyaka kusungidwa mu chipinda chomwecho.

2. Masilindala a oxygen aziikidwa mowongoka, ndikuchitapo kanthu kuti apewe kuwongoka.

3. Malo omwe masilinda a okosijeni amasungidwa asakhale ndi ngalande kapena ngalande zakuda ndikukhala kutali ndi malawi otseguka ndi magwero ena otentha.

4. Musagwiritse ntchito mpweya wonse mu silinda, koma siyani mphamvu yotsalira kuti mupewe kutuluka kwa mpweya wina.

(B) Kunyamula

1. Masilindala a okosijeni ayenera kunyamulidwa pang'ono ndikutsitsa, oletsedwa kuponya poterera, kukhudza kukhudza kupewa kuphulika.

2. Osagwiritsa ntchito njira zonyamulira zothimbirira mafuta potengera masilindala okosijeni.Kuthimbirira pakamwa pa botolo kapena kukhudzana ndi zonona kungayambitse kuyaka kapena kuphulika. 

3. Yang'anani ngati valavu ya pakamwa ya silinda ndi mphete yotetezera mphira ya shockproof yatha, kapu ya botolo iyenera kutsekedwa ndipo pakamwa pa botolo mulibe mafuta musanagwire. 

4. Masilinda a gasi sangathe kukwezedwa, sangathe kugwiritsa ntchito makina a electromagnetic pokweza ndi kutsitsa masilindala a gasi, kuteteza kugwa kwadzidzidzi kwa ma silinda a gasi kuphulika.

(C) Kugwiritsa ntchito

1. Kugwiritsa ntchito silinda ya okosijeni kuyeneranso kuchitapo kanthu kuti mupewe kupotoza, ndi zida zonse zotetezera, kugogoda, ndi kugunda ndikoletsedwa. 

2. Masilindala a okosijeni olumikizidwa ku chipangizo chochepetsera kupanikizika musanayambe komanso pambuyo pake kuyeza kwamphamvu kumayenera kukhazikitsidwa.

3. Masilinda ovala zipewa.Mukamagwiritsa ntchito gasi, kapu imayikidwa pamalo okhazikika, ndipo kapu imayikidwa mu nthawi yake mukatha kugwiritsa ntchito.

4. Mukamagwiritsa ntchito silinda ndikoletsedwa kwambiri pafupi ndi gwero la kutentha, bokosi lamagetsi, kapena waya wamagetsi, musamawonetsere dzuwa.
