Abstract

The designs of the variable frequency constant pressure water supply for a single hydraulic pump and high power multiple hydraulic motors systems are presented in this paper. This system can save energy by controlling the speed of the pipe motors which depend upon the number of consumers in use. This system was also successfully implemented in most of the modern buildings in Shanghai, China. Finally, the choice criteria for variable frequency regulators for the water supply system is discussed
