Optimization Analysis Of Operation Mode Of Secondary Booster Pump Station In Shenyang

The tap water supply technology has been used in the main urban area of Shenyang for nearly a hundred years.With the increase of high-rise buildings in the city,the primary pressure water supply can not meet the requirements of urban industrial production and residents’ life.The city center of Shenyang is a low-pressure water supply system,and the residents’ domestic water is generally supplied by two times of pressure.The second booster pump station in Shenyang was generally built in 1980s and 1990s.There are many problems of the pump station,such as long time ago,low standard of early construction,inadequate management,unreasonable configuration of the original secondary pressurized water supply facilities,unreasonable selection and design of water pump,which lead to unstable operation and high energy consumption of the pump station.The traditional operation mode has low efficiency and high energy consumption.In addition,the original management mode is not only backward,but also consumes a lot of labor costs.The existing water supply facilities and technology in Shenyang are relatively backward,coupled with the rising labor costs,resulting in the reduction of production profits or even losses of enterprises,forcing enterprises to think about how to fine management.In order to solve the water demand of residents,industry and commerce,and reduce the operation cost of water supply enterprises,the secondary booster pump station needs to be optimized.In this paper,the existing secondary booster pump station in Shenyang City is taken as the research object.By analyzing the water supply situation of the urban pipe network,the operation situation,energy consumption and other existing problems of the existing pump station are investigated,and the old pump station is selected and upgraded.Through the optimization research of pump station infrastructure,such as water pump and reservoir,the unreasonable secondary booster pump station in Shenyang is solved,the number of which is 36.7% of the total number of existing operating pump stations.The analysis of water supply mode shows that The first district pump station accounts for 70% of the total number of pump stations in the city,the second district pump station accounts for 20%,the third district pump station accounts for 9%,the fourth district pump station and the fifth district pump station account for1%.Compared with the traditional operation mode,the new energy-saving operation mode is studied,which shows that the utilization of the residual pressure of the pipe network can effectively reduce the energy consumption of the secondary booster pump station and improve the quality of water supply.Finally,this paper established a remote transmission supervision platform based on the original management model.This method solves the problem of labor consumption in traditional management mode.In addition,the remote monitoring platform plays an important role in energy saving,and the platform system provides the basis for the refined management of secondary booster pump station.
