交流电动机变频调速是近20年内发展起来的新技术,而在我国的普及应用,则大约只有10余年。变频技术应用在供水系统就更是后来者,变频调速恒压给水技术自20世纪80年代初经过萌芽,现已在我国广泛使用,从设计院、安装单位到供水设备生产厂家为变频供水的普及作出了不懈努力。全国各种建筑群已广泛采用变频供水设备,就是最好的证明。
AC motor speed control is developed within the last 20 years of new technology, while in our country’s popularization and application, only about 10 years. Frequency conversion technology is even more late in the water supply system, frequency control water supply technology since the early 1980s after the sprout has been widely used in our country, from the design institutes, installation units to the water supply equipment manufacturers for the frequency of water supply Popularization has made unremitting efforts. Various buildings throughout the country have been widely used frequency conversion water supply equipment, is the best proof.
