摘  要：換熱站作為供熱網(wǎng)路與熱用戶之間的連接場所，其供熱品質(zhì)對熱網(wǎng)工況的改善和供熱質(zhì)量的好壞起著重要作用。換熱站變頻調(diào)速控制系統(tǒng)主要由PLC控制器、變頻器和PID控制器及調(diào)節(jié)閥組成，本文主要針對換熱站循環(huán)水泵和補水泵變頻控制進行設計。 關鍵詞：循環(huán)水泵；補水泵；變頻調(diào)速；PLC Abstract: Heat exchanger station as the connection between the heat supply network and heat users, the heating quality and heating on the improvement of the working condition of the heat-supply quality plays an important ro[登陸后可查看全文]
