Research On Energy Saving Technology Of Water Supply System In Mountain Small Towns

Water supply system is one of the most important fundamental facilities in a small town. With the fast development of small towns in our country, the water supply system of small towns is developing rapidly. Water supply system in mountain small towns is weak, because of poor economy and complex terrain, some existing water supply facilities age and lack of management that leads to the high consumption and burdens the economic of the enterprise.This paper combiles the feature of the water supply system of mountain small towns, researches the measures to reduce consumption of water supply system, including zone water supply, water intake pumping station, water pumping station and pipes. The following will be the main content and conclusion.(1) Energy saving analyse of water supply in mountain small townsThe landform of mountain small towns is complex, there are many difficulties in water supply system. We should combine with the layout of the towns to adopt zone water supply reasonable, and fix on the optimal zone position by energy distribute figure. Long delivery pipes in mountain small towns introduced line pump not only make the most of super-pressure, but also uneasily happen the accidents of vacuum.(2) Design and reconstruct of the water intake pumping station.At percent, design methods of the water intake pumping station are irrationality. this text analyses the most unfavorable conditions of water intake pumping station, and brings forward modified method to make the designed conditions and working conditions keep consistent, so the efficiency of pumps is be improved.. What's more, it sets down the scheme to reconstruct the water intake pumping station by means of impeller cutting and Timing pump, and makes certain the range of static head when the pump working in highest hydraulic efficiency, ensuring pump run in high efficiency.(3) Water pumping station energy saving.Setting up the upland tank and variable speedy pump are the accommodation mode. And the capability of water quality is inferior, although upland tank energy saving than variable speedy. The fall of landform in mountain area is great, static head is great too, and energy effect of imposing which adopts in constant press and frequency conversion is high. so it is suitable to be adopted by the water supply system in mountain small towns.Timing pump and constant pump usually run by parallel connection, scheme in...
