KONENTI POMPI PAPO

Chiyambi cha Papo Papo: Kusintha Mwachangu Ntchito Yomanga

Chitoliro chopopera, chomwe chimadziwikanso kuti chitoliro cha pampu ya konkriti, ndi chida chosinthira makina opangira makina omwe amathandizira kwambiri pakumanga konkriti. Mtundu watsopano wa zida zamakina omanga zimadza limodzi ndi makina omangira konkriti, zomwe zimapangitsa kukhala gawo lofunikira pantchito iliyonse yamakono yomanga.

Mapaipi opopera madzi nthawi zambiri amatchedwa mapaipi apampu apansi, kuphatikiza mapaipi olunjika apansi ndi zigongono zapampopi. Mapaipiwa amapangidwa makamaka ndi 20 # carbon steel, yomwe imadziwikanso kuti Q235B. Njira yopangirayi imaphatikizapo zowotcherera zitoliro zopanda msoko ndi kuponyera, kutsatiridwa ndi kulumikizana kwa chitoliro. Kupanga mwaluso kumeneku kumatsimikizira kulimba komanso kudalirika kwa machubu a pampu.

Malinga ndi zofunikira zosiyanasiyana zogwirira ntchito, mapaipi amapampu amagawidwa kukhala otsika kwambiri, kuthamanga kwambiri komanso kuthamanga kwambiri. Mwachitsanzo, pali mitundu yambiri ya mapaipi apansi olunjika monga DN80, DN100, DN125, ndi DN150. Mitundu ya DN80 ndi DN100 imagwiritsidwa ntchito kwambiri pamapampu amatope ndipo nthawi zambiri amatchedwa mapaipi ampopi amatope kapena mapaipi amatope. Kumbali inayi, DN125 ndiye chitoliro chopopera cha konkriti chomwe chimagwiritsidwa ntchito kwambiri pamakina otsika.

The awiri akunja chitoliro DN125 ndi 133mm, ndi makulidwe a thupi chitoliro ndi 4.5-5mm. Njira yowotcherera yokha ya 25mm yokhazikika ya flange imatengedwa kuti iwonetsetse kuti payipi ndi yabwino komanso kukhulupirika. Mapaipi apansi awa ndi abwino poyika konkriti yotsika komanso ntchito zina zokakamiza.

Pakugwiritsa ntchito kuthamanga kwambiri komanso kopitilira muyeso, kutalika kwakunja kwa chubu chapampu kumachulukitsidwa mpaka 140mm. Makulidwe a khoma la mapaipi othamanga kwambiri ndi 6mm, ndipo makulidwe a khoma la mapaipi apamwamba kwambiri ndi 8mm kapena 10mm. Zokhala ndi ma flange 175 mm kapena 194 mm komanso ma flanges a zilembo, mapaipi awa adapangidwa kuti azitha kugwira ntchito movutikira.

Kuphatikiza pa milingo yosiyanasiyana ya kuthamanga, machubu amapope amapezeka mosiyanasiyana, kuphatikiza 0.3m, 0.5m, 1m, 2m ndi 3m. Utali ukhozanso kusinthidwa kuti ukwaniritse zofunikira za polojekiti.

Ponseponse, mapaipi opopera amagwira ntchito yofunika kwambiri popereka konkire mwachangu komanso moyenera pantchito yomanga. Kupanga kwake kolimba komanso kukakamiza kosiyanasiyana kumapangitsa kuti ikhale yofunika kwambiri pamitundu yonse ya ntchito zopopera konkriti. Ndi chitoliro chopopera, ntchito yomangayo yawonjezeka kufika pamlingo womwe sunachitikepo, ndikutsegulira njira yomanga yofulumira, yotsika mtengo.
