Research on Economy for Puplic Water Feeding System
|Title||Research on Economy for Puplic Water Feeding System|
The original together is the research target with the puplic water feeding system in Guangzhou power station limited company. Is aimed at all to adopt rotating speed control stably admittedly to the water pump, adopts control to run pump amount and type the control gives the discharge , being living to have ariseed to shift below the distinct burden situation such as top and so on , and constantly need to transforing manipulating to the water pump , therefore it is tall to create block the leading to the water pump , the effect is to the water system secure operation together , adoping moreover the transformation to regulate to discharge to the water pump means , it is finite to regulate the measure , it is tall strenuously with prejudice against what the boiler needed to hydraulic pressure equally strenuously to opposite to each other to hydraulic pressure , creates problems such as energy waste and so on , comparatively more different the most splendid defects of the control mode gives the water pump , and proposes to the water system together to plus to pack the high-handed transmission , and achieves together economically ruing , and utilizes , and establishs together economically ruing the analytic modelling to the water system to water pump H-Q’s characteristic to the water system , thereby the optimum certain save energy reconstruction schemeIn addition, after high-voltage inverter water supply system installed, it run more tests to optimize the way. Analysis the economic of test results and determine the best operation mode .The way is indeed has good effect: the water and electricity consumption is reduced from 5.20 kWh / t to 5.00 kWh / t, reducing by 0.2 kWh / t. of water, and energy-saving rate was 3.9%, saving the cost of production about 73 million yuan,which has made the more obvious energy saving effect; reduce water pressure fluctuations, thereby reducing the boiler water level and water temperature fluctuations in the boiler and improve safety of the boiler; avoid the frequent start-stop of the pump and reduce the labor intensity; avoid the impact of current motor starting and improve the pump to run more securityMoreover , is living together to fix high-handed frequency converter queen , and is living to optimize the relation test on the run mode , and to the eperiment kill that the economy analyses , and fixd the optimum run mode to the water system . That that the original still adjust to the water system together the systematic pressure difference of warm water afterwards reforming to complete being that workman’s frequency pump passes through the rate of flow and reduces is with prejudice little and the water pump balancing frame wornout is give in the frequency conversion and the boiler to water regulates that the door exerts oneself is insufficient and so on , and the problem is analysed , and proposes resolving the step , and gurrantees to the water system together security and economically runs .
