Kodi Mungasankhire Bwanji Kuthamanga Kwambiri kwa Mpweya Pansi pa Bowo?

M'mapulojekiti obowola mwamphamvu kwambiri, kuti mukwaniritse cholinga chobowola bwino komanso mwachangu, ndikofunikira kusankha zobowola zapamwamba komanso zogwira mtima, ndiye kuti, kusankha pansi. -bowola mabowo okhala ndi zida zosiyanasiyana molingana ndi njira zoboola zosiyanasiyana komanso mitundu ya miyala. Zinthu zingapo monga kubowola kumapeto kwa nkhope, mawonekedwe a pobowola ufa, mawonekedwe a dzino la carbide ndi kukula kwake, kuuma kwa thupi la kubowola, etc. , kubowola pang'ono moyo ndi ntchito bwino. Chifukwa chake, kusankha pobowola koyenera ndikofunikira kwambiri pantchito zoboola miyala.

Pankhani yobowola mothamanga kwambiri (zobowola) pali mitundu inayi yayikulu yopangira nkhope yomwe imagwiritsidwa ntchito pano, yomwe ndi: mtundu wa nkhope yopindika, kusalala kwa nkhope, mtundu wa nkhope yopindika ndi nkhope yozama. mtundu wa concave center. Carbide nthawi zambiri amagwiritsa ntchito mano a mpira, mano a masika kapena ampira ndi mano a masika pokonza mano.

1. Mtundu wa nkhope ya convex: Mtundu wa nkhope ya convex wa mtundu woponderezedwa kwambiri wobowola (bowolo) umatha kukumba mokwera kwambiri pobowola miyala yolimba yolimba komanso yolimba, koma kuwongokako sikungayende bwino, ndipo siyoyenera ntchito yoboola miyala yokhala ndi zofunika kwambiri pakuwongoka kwa blasthole.

2. Mtundu wa nkhope yathyathyathya: Mtundu wa nkhope yakuphwanyidwa: Chobowola chapamwamba chotsika pansi (bowolo) chimakhala champhamvu komanso cholimba, ndipo ndi choyenera kubowola miyala yolimba komanso yolimba kwambiri. Ndiwoyeneranso kubowola miyala yapakati-yolimba ndi mwala wofewa wokhala ndi zofunikira zochepa pakuwongoka kwa blasthole.

3. Mtundu wa nkhope ya concave end: Mtundu wa nkhope ya concave end-high-pressure down-the-hole kubowola (bowola) uli ndi gawo lopindika kumapeto kwa nkhope, zomwe zimapangitsa kuti kubowolako kupangike pang'ono pobowola mwala. process, imasunga magwiridwe antchito a pobowola, ndipo chobowoleracho chimakhala chowongoka bwino. Komanso, pobowola pang'ono ili bwino fumbi kuchotsa zotsatira ndi mofulumira pobowola liwiro. Ndikobowola kotsika kwambiri komwe kumagwiritsidwa ntchito kwambiri pamsika.

4. Kumapeto kwa nkhope yozama ya concave pakati: Kumapeto kwa nkhope yozama ya concave center mtundu wothamanga kwambiri wa mphepo pansi pa dzenje (bowola) ili ndi gawo lakuya lapakati pakati pa nkhope yomaliza, yomwe imagwiritsidwa ntchito popanga nyukiliya mkati. njira yobowola miyala. Kubowola mabowo akuya kungathe kusungitsa kuwongoka kwa blasthole, koma mphamvu yake yakumapeto ndi yofooka kuposa mitundu ina ya kubowola, kotero ndiyoyenera kubowola mwala wofewa ndi mwala wolimba.
