Mapampu a DL ndi DLR amagwera m'gulu la mapampu oyimilira amodzi omwe ali ndi magawo angapo a segmental centrifugal omwe amagwiritsidwa ntchito kunyamula madzi oyera omwe alibe tinthu tating'onoting'ono kapena zakumwa zina zokhala ndi thupi ndi mankhwala ofanana ndi madzi oyera.Amagwiritsidwa ntchito makamaka popereka madzi okwera kwambiri komanso popereka madzi ndi ngalande m'mafakitole ndi migodi.Kuthamanga kwa madzi onyamulidwa ndi 4.9 ~ 300m³ / h, mutu wokweza mutu 22 ~ 239m, mphamvu yokhudzana ndi 1.5 ~ 200kW, ndi m'mimba mwake range40 ~ 200mm.
DL ndi DLR mndandanda mapampu ndi ntchito kwa mafakitale ndi m'matauni madzi ndi ngalande, pressurization ndi kotunga madzi kwa mkulu-nyamuka ndi kulamulira moto, madzi mtunda wautali, pressurization madzi ozizira ndi otentha kufalitsidwa kwa Kutentha, bafa ndi boiler, madzi. ya air-conditioning refrigeration system, zopangira zida ndi zina zotero.Kutentha kwapakati pakugwira ntchito kwa mtundu wa DL sikuyenera kupitirira 80C pomwe kwa DLR sikudutsa 120 ℃.
