Q: Kodi ndi zinthu ziti zomwe ziyenera kunyamula chidwi pakukhazikitsa, kugwiritsa ntchito ndi kukonza valavu yoteteza chitetezo?

A:

Zofunikira zomwe zimafunikira chisamaliro mu kukhazikitsa, kugwiritsa ntchito ndi kukonza ma mavavu otetezeka

Mavavu oyenera a Device ndiofunika kwambiri, ndiye kuti ayenera kusamalira chiyani pakukhazikitsa, kugwiritsa ntchito ndi kukonza valavu ya chitetezo?

Vutoli loteteza kuti likhale lofunika kuonetsetsa kuti lidzagwire ntchito yotetezeka komanso yolimba. Komabe, ngati wogwiritsa ntchito sazigwiritsa ntchito moyenera, valavu yoteteza siyingagwire ntchito bwino, kotero kukhazikitsa ndi kugwiritsa ntchito ndizofunikira kwambiri. Zina mwazomwe zimanenedwa ndi ogwiritsa ntchito, zolephera za chitetezo zomwe zimayambitsidwa ndi kuyika kosayenera ndikugwiritsa ntchito akaunti ya 80%. Izi zimafuna ogwiritsa ntchito kuti azitha kusintha chidziwitso cha chitetezo cha chitetezo ndi ukadaulo komanso momwe amagwirira ntchito mosamala kwambiri.

Ma Valves otetezeka ndi zida zowerengeka komanso zomwe zimafunikira kuyika ndikugwiritsa ntchito. Kuti mafakitale opitilira, zida zimamangidwa, zimadutsa njira zingapo monga kuyeretsa, mpweya wolimba, komanso kuyezetsa, kenako ndikutumiza. Vuto lodziwika ndi ogwiritsa ntchito ndikukhazikitsa valavu yoteteza panjira yomwe ikutsuka. Popeza valavu yachitetezo ili pamalo otsekeka, zinyalala zimalowa mu valavu ya chitetezo panthawi yoyeretsa. Panthawi yoyesa, valavu ya chitetezo imadumpha ndikubwerera. Chifukwa cha zinyalala atakhala, valavu yoteteza idzalephera.

Malinga ndi miyezo ya National, njira zotsatirazi ziyenera kumwedwa poyeretsa:

1. Valavu yoteteza imaloledwa kuyikidwa pa pulogalamuyi patatu, koma mbale yakhungu iyenera kuwonjezeredwa ndi valavu ya chitetezo kuti isindikize.
2. Popanda kukhazikitsa valavu yacitchire, gwiritsani ntchito mbale yakhungu kuti isindikize kulumikizana ndi Vuto Lachitetezo ndi njirayi payipi, ndikubwezeretsa valavu yoteteza ikamalizidwa.
3. Ngwaya za chitetezo zimatsekedwa, koma pali chiwopsezo muyeso. Wogwiritsa ntchitoyo akhoza kuyiwala kuti achotse chifukwa cha kusasamala, kupangitsa valavu yoteteza chitetezo kuti isagwire bwino ntchito.

Ntchito yogwira ntchito iyenera kukhala yokhazikika pakugwiritsa ntchito. Ngati kupatuka kwamphamvu kwakanikirana, kumapangitsa valavu yotetezedwa kudumpha. Malinga ndi miyezo ya National, valavu ya chitetezo ikadumphira, iyenera kuyandikira.

Kuphatikiza apo, magawo aluso operekedwa ndi wogwiritsa ntchito ayenera kukhala olondola, ndipo sing'anga yofunsira iyenera kukonzedwa. Mwachitsanzo, sing'anga mu magawo aluso amaperekedwa ndi mpweya, koma ngati chlorine ikasakanikirana ndi izi pakugwiritsa ntchito, chlorine ndi nthunzi yotentha imaphatikizika kuti apange ma hydrochloric acid, yomwe idzawononga valavu ya chitetezo. Zimayambitsa kuwononga; Kapenanso sing'anga mu magawo aluso omwe amaperekedwa ndi madzi, koma sing'anga weniweni amakhala ndi miyala, yomwe idzayambitsa valavu ya chitetezo. Chifukwa chake, ogwiritsa ntchito sangasinthe magawo a chifuniro. Ngati zosintha zikufunika, ziyenera kuona ngati valavu yoperekedwa ndi wopanga valawo ndi yoyenera kusinthira ndikulankhulana ndi wopanga munthawi yake.

Ngati pamwambapa titha kugwira ntchito molondola malinga ndi mitundu yosiyanasiyana, valavu yoteteza iyenera kuyesedwa chaka chilichonse, ndipo wothandizirayo ayenera kupeza satifiketi yapadera. "
