中文摘要：

采用循环水模拟装置,在相同流量、相同温度条件下,研究了管道形状、管道口径对超声防垢率的影响.结果表明,管道形状、口径对超声防垢率均有一定影响.在相同频率、相同功率超声作用下,直管处局部防垢率比弯管、变截面管处局部防垢率高,但对循环系统,总的防垢率相差不多;在相同频率、相同声强超声作用下,直管口径越大,直管处局部防垢率越高.

Using the simulator of circulating water,the effect of pipeline parameters on results of ultrasonic antiscale are studied,of which the caliber of pipeline and the geometry of pipeline are the major factors influencing the ultrasonic antiscale rate when the fluid temperature and flow rate are the same.It is proved that when the frequency and intensity of ultrasound are the same,the local antiscale rate in straight tube is higher than that in elbow and variable caliber ones,but the whole antiscale rates of th...
