a case based reasoning approach for estimating the costs of Pump Station projects
Journal of Advanced Research, 2011Co-Authors: Mohamed Marzouk, Rasha M AhmedAbstract:Abstract The effective estimation of costs is crucial to the success of construction projects. Cost estimates are used to evaluate, approve and/or fund projects. Organizations use some form of classification system to identify the various types of estimates that may be prepared during the lifecycle of a project. This research presents a parametric-cost model for Pump Station projects. Fourteen factors have been identified as important to the influence of the cost of Pump Station projects. A data set that consists of forty-four Pump Station projects (fifteen water and twenty-nine waste water) are collected to build a Case-Based Reasoning (CBR) library and to test its performance. The results obtained from the CBR tool are processed and adopted to improve the accuracy of the results. A numerical example is presented to demonstrate the development of the effectiveness of the tool.

Discussion on Utilization of Residual Pressure in Secondary Pressure Pump Station
Construction Conserves Energy, 2007Co-Authors: Yao HongAbstract:System structure and operating principle of a new-style secondary pressure water supply device were introduced.Through analyzing five different working states of the device,the result shows that flow rate of inlet and outlet and the inlet pressure are the key factors of impacting energy saving.Comparing with general water supply system and direct pressure-add water supply technology,this new-style secondary pressure water supply device has wider prospect of application.Moreover,some problems should be noticed in application of this new device.

Utilization of residual pressure in booster Pump Station
2003Co-Authors: Yao HongAbstract:The utilization of the residual pressure at a booster Pumping Station can save energy by 10 to 40 percent on the basis of the frequency-change Pump working,and save bulk of feeding reservoir by about 50 percent,and reduce initial stages investment.The efficiency formula of the utilization of the networks residual pressure at a booster Pump Station was summarized,which provided the theoretic foundation for advanced study on the utilization of the residual pressure in a booster Pumping Station.

Technical Reform of a Sewage Pump Station
Journal of Xihua University, 2009Co-Authors: Wang Hong-weiAbstract:A kind of vertical sewage Pump is used as upgrade Pump in some sewage treatment plants.Because the actual set lift is a little lower,the efficiency is less than that of design.Therefore,instead of primary vertical sewage Pump,axial Pump is used as dry-type Pump in sewage Pump Station.The sewage Pump Station of a sewage treatment plant is reformed.After the reform,the performances and economic benefits are greatly improved.The results of the technical reform are of references for the design and reform of similar projects.

Mitsubishi PLC application to automatic control of the Pump Stations
Water Sciences and Engineering Technology, 2006Co-Authors: Deng JAbstract:The automatic control system of Pump Station taking PLC as the core, has improved the comprehensive automation level of the Pump Station greatly. The paper has introduced application in the automatic control system of Pump Station of FX2N serial programmable controllers (PLC) of Japanese Mitsubishi Company mainly. Such problems as communication problems of the location paying machine (IFIX) and the next machine (PLC), and how small-scale PLC of many FX2N series gather the data, the data interchange and communication and so on. Besides this, system forming and systematic function of the Pump Station of control system are provided.
