Recently, the urban and rural water supply integration improvement and guarantee project in Pingyin County, Jinan City, which was won by Nanfang Pump Industry, has been successfully completed. The project aims to ensure the quantity and quality of domestic water for local urban and rural residents, fundamentally solve people's livelihood problems, and drive local economic development. With its professional technical strength and efficient construction team, Nanfang Pump Industry has successfully assisted the smooth implementation of the project.
Project Overview
The urban and rural water supply integration improvement and guarantee project in Pingyin County, Jinan City, gradually replaces water supply sources such as the county town and Ancheng Town through the construction of Wangying underground water source, Cuidong Water Plant and the laying of about 16 kilometers of water distribution pipelines, thereby comprehensively solving the drinking water problem in the urban area. As the winning bidder, Nanfang Pump Industry undertook the supply, installation and commissioning of key equipment.
Nanfang Pump Industry Demonstrates Excellent Capabilities
Technical Strengths
Nanfang Pump Industry has its own precision machining casting factory and the world's advanced automated precision machining center to ensure the reliability and timeliness of castings.
Intelligent control
In view of the long distance between the newly built Wangying water source and the water plant and the large changes in water consumption during different periods of time, Nanfang Pump Industry provided efficient ABB variable frequency control cabinets and intelligent PLC data control systems. The system can automatically start and stop the water pump according to the water consumption of the water plant, realizing intelligent interlocking control, which not only improves the efficiency of the water pump, but also significantly reduces the operating cost.
Professional installation and service
During the installation of pump room equipment, Nanfang Pump Industry implemented it in accordance with the installation and commissioning requirements and specifications to ensure the installation accuracy of the pump unit, optimize the pipeline layout, and reduce hydraulic losses by more than 15%. In terms of after-sales service, Nanfang Pump Industry has established a 124 response mechanism and equipped with a professional operation and maintenance engineer team, promising to respond within 1 hour, arrive at the site within 2 hours, and solve routine problems within 4 hours. This "full life cycle" service concept not only ensures the stable operation of the project, but also reflects the "customer-centric" professional service spirit of Nanfang Pump Industry.
Advantages in large-scale water supply and drainage projects
High efficiency and energy saving
NSC single-stage double-suction split centrifugal pump adopts advanced fluid dynamics design and customizes coating solutions according to the water quality of Pingyin County, making the pump more efficient and energy-saving, achieving a 40% increase in the comprehensive energy efficiency of the water supply system, and meeting the high requirements of the Pingyin County urban and rural water supply integration improvement and guarantee project.
Stable and reliable
The double suction port realizes symmetrical fluid input, and the axial force self-balancing design increases the bearing life by 30%-40% compared with the single-suction pump, and the operation is more stable. After the water plant adopted this pump type, the daily average water supply pressure fluctuation of 50,000 tons was stably controlled within ±0.02MPa, which is better than the national standard requirements.
Easy maintenance
The pump body is designed to be split horizontally along the axis, and the core components such as impellers and bearings can be directly maintained without disassembling the pipeline or motor. During the construction of the Jinan Pingyin project, this feature increased the equipment maintenance efficiency by more than 50%, and the double sealing ring low-friction technology made the water pump life longer, effectively ensuring the continuous operation requirements of the 16-kilometer water transmission network.
Full life cycle benefits
The modular design combined with the intelligent operation and maintenance platform saves more than 40% of the comprehensive operating cost compared with traditional pumps, which meets the requirements of the Pingyin County "from water source to tap" full process intelligent monitoring system.
