Through experiments, the double pump operation mode was compared with the single pump operation mode under different temperatures and different loads. 通過(guò)試驗闡述循環(huán)水泵在不同溫度和機組負荷下進(jìn)行雙循環(huán)泵運行改單循環(huán)泵運行的比較。
Economics is studied on steam injector substituting the tube-shell heat exchanger and the circulating pump in the heating system of the thermal power plant. 針對熱電廠(chǎng)供熱系統采用升壓加熱裝置改造熱網(wǎng)加熱器和循環(huán)水泵的可行性和經(jīng)濟性開(kāi)展了研究。
