| Abstract: | We introduced a double passage integrating circuit,which could automatically convert the working frequency within the upper and lower frequency limit. Applying this technology,the author designd the PLC controlled, frequency conversion high rise water feed system,which consisted of mini PLC, the transducer and three parallel water pumps. The long term operation indicated that each pump cycle was in good condition and electrical power can be saved by 40%. Therefore, it is a reliable and energy saving method for high building water supply of the modern city. |
