目前，矿井常用离心式水泵有单级单吸式离心泵如Ｂ型．单级双吸式离心泵如ＳＨ型，单吸多级分段式离心泵如Ｄ型，吊泵如ＤＬ型，潜水泵如ＱＹ型等等，其中最常用的离心泵是Ｄ型．其效率较高。但是，总的来说国产离心泵效率较低，仅为６Ｏ％一８０％，而其中ＺＯＯＤ．４３Ｘ２
At present, the centrifugal pump used in the mine has a single-stage single-suction centrifugal pump such as type B. Single-stage double-suction centrifugal pumps such as SH type, single-suction multistage centrifugal pumps such as D-type, hanging pumps such as DL-type, submersible pumps such as QY-type, etc., of which the most common centrifugal pump is D-type. Its efficiency is higher. However, in general, the domestic centrifugal pump is less efficient, only 6O% to 80%, of which ZOOD. 43X2
