Project And Implementation Of Energy-Saving Reconstruction Of Pump Set For Jieyuan Water Plant

A water plant is usually equipped with several pump sets, which are majorpower-consumed equipments. With the increase of power tariff for industrialenterprises nowadays, the power costs have become significant costs for the waterplant. Therefore, the technology reformation of pump sets, enhancement of pumpingsystem efficiency, and reducing energy loss will be the key to reduce power tariff. Forthe new water plants, water pump type and specifications could be selected to fit thecharacteristics of pipe network. However, for the outmode water plants just likeJieyuan, the energy-saving reconstruction for the pumping system will be the mosteffective way.The papers main work is as follows：1．With the instances of water plant renovation projects at home and abroad, a lot ofreconstruction projects of the pump sets are explored; comprehensive comparison ofvarious methods is done, and the characteristic and suitable occasion of differentreconstruction method are recognized.2．According to Jieyuan Water Plant pump sets situation, the consistent condition ofthe parameters of the pumps to the pipe network is analyzed, and the reason for thehigh energy consumption of the pumps is found out, the available reconstructionmethods are inspected.3．Frequency control for water pump set is investigated, and combined with the actualsituation of Jieyuan Water Plant，several projects of pump set reconstruction areproposed. By means of comparing economy and feasibility for different projects, theproject is at last determined with changing pump sets and retrofitting frequencycontrol.4．By using network plan technique to plan the project of pump sets reconstruction,the duration of a project is shortened, and the resources are utilized sufficiently andeffectively, which creates nice economic benefits for enterprise.
