Recently, Jinan City east water supply four reservoir connected water supply project successfully test water, the project four pumping stations using FGI production of 8 sets of high voltage inverter, has been successfully debugging and put into operation.
1.project context
The shortage of water resources is the bottleneck of Shandong's national conditions and economic and social development. Jinan, which is close to water, has continuously gathered population and resources and continuously expanded its urban scale in the process of urbanization, which puts forward a higher demand for its emergency water supply capacity.
In order to alleviate the problems of economic development and ecological environmental water use in the east of Jinan city, Jinan Urban and Rural Water Bureau plans to construct the east of Jinan water source four reservoir connectivity project, which takes the Yangtze River water and Yellow River water of Donghu Reservoir and Baiyun Reservoir as the water source, transfers water to Wolf Mushan Reservoir and Duzhang Reservoir for ecological water replenishment, and supports the construction of four pressurized pumping stations and water transmission pipelines.
2.Project difficulty
The project consists of three parts: water diversion pipeline, four booster pump stations and water diversion pipeline. The water transmission pipeline runs from north to south through Zhangqiu District, Licheng District and Jinan High-tech Development Zone, spanning 41 administrative villages. The line is cross-laid with municipal communication cables, civil hydropower and other pipelines, and crosses railway, expressway and other infrastructure in many places. The underground environment of the construction surface is very complicated and the construction is very difficult.
After winning the bid for the project, FGI attached great importance to and actively cooperated with the project construction, sent technical support engineer Zhang Kai and key account manager Song Yule to the project site, repeatedly communicated with the customer and studied the technical plan, worked diligently and actively coordinated during the project commissioning, and completed the node target set by the superior leadership with quality and quantity, ensuring the normal trial operation of the project.
3.application effect
The project makes full use of the storage capacity of each reservoir, realizes the joint operation of the Yellow River water, the Yangtze River water and the local surface water and the optimal allocation of water resources, and can supply 400,000 cubic meters/day to the Wolf Mushan Reservoir and 200,000 cubic meters/day to the Tourism Road water plant, greatly improving the water supply capacity and water supply guarantee rate of Jinan City and the surrounding areas. At the same time, it plays an important role in ensuring the ecological replenishment of river channels, improving the ecological environment of river channels and enhancing the image of cities.
4.Features of FGI scheme
(1) Achieve constant water pressure water supply
FGI high voltage frequency inverter speed range is wide, high precision, the pump can change the water level according to the process needs;
(2) Unit flexible starting
The use of FGI high voltage frequency inverter to start, the process is stable, reduce the starting current, has been recognized by the user;
(3) Reduce water and electricity consumption
Use FGI high voltage inverter to adjust the voltage and frequency of the pump, so that the output flow and pressure of the pump can be adjusted at any time to achieve the purpose of saving energy;
(4) Stable and reliable performance
FGI high voltage frequency inverter has a number of protection functions, better protect the motor, the system runs smoothly and reliably;
(5) Reduce maintenance intensity
After using FGI high voltage inverter, the user's maintenance workload is reduced, the maintenance cost is reduced, and the practical value is brought to the user.
In conclusion, the application of FGI's high voltage frequency converter in the connecting project of four water sources in the east of Jinan City has been a resounding success. Our advanced technology, customized solutions, and collaborative partnership approach have contributed to the efficient and reliable operation of the water supply system, benefitting the residents and businesses in the region. As we continue to expand our presence in the field of frequency conversion technology, FGI is committed to delivering innovative solutions that drive positive outcomes for critical infrastructure projects like the one in Jinan City.
