摘 要: | 随着城市供水管网加压泵站数量的逐年增加,其运行过程中耗电量亦递增,这将造成巨大的能源浪费和经济损失。为实行节能降耗,基于水力模型优化加压泵站,以J市M地区加压泵站为试验区域,提出3种节能方案进行对比分析。结果表明,将加压泵站全天分为高低峰时段,高峰用水时段不实施节能工作,低峰用水时段实施节能工作的方案节能降耗效果最佳,且节能期间平均千立方水耗电较2014年11月降低0.35%,较2014年12月降低3.97%,较2015年1月降低5.16%,较2015年2月降低7.49%,较2015年3月降低5.10%。

Optimizing Energy saving and Consumption reducing of Pressurized Pumping Station Based on Hydraulic Model |

Abstract: | As the number of urban pressurized pumping stations in water supply pipe networks has been increasing year by year, the power consumption of pumping stations is also increasing. This will result in huge energy waste and economic losses. In order to implement energy saving and consumption reduction, this paper optimizes the pressurized pumping station based on the hydraulic model. Taking the pressurized pumping station in the M area of J City as the test area, three kinds of energy saving schemes were proposed for comparative analysis. The test results show that the pressurized pumping station is divided into high and low peak hours throughout the whole day, no energy saving is implemented during the peak water use period, and the scheme for implementing energy saving work during low peak water use time is more energy efficient and energy conserving, and the average energy consumption per kilometre of water during energy saving period is higher than 2014. Decrease was 0.35% in November, which was a decrease of 3.97% from December 2014, a decrease of 5.16% from January 2015, a decrease of 7.49% from February 2015, and a decrease of 5.10% from March 2015. |
