A. Project Overview

    Project name: Living pump room system in the basement of Baihe Xinyuan, Wuyi, Nanping, Fujian Province

    Project location: Basement of Baihe Xinyuan Community, Wuyi, Nanping City, Fujian Province

    Project content: Complete water supply system design, equipment supply, installation and commissioning and system integration for domestic pump rooms

    Project status: It has successfully passed the completion acceptance, the system is running stably, and all indicators meet the design requirements.

B. Project background and requirements

Wuyi Baihe Xinyuan is a newly built residential complex. In order to solve the problems of unstable water supply pressure, high energy consumption, hygienic water storage and system automation control for high-rise residents in daily life, it is necessary to build a high-efficiency, energy-saving and intelligent domestic pump room water supply system. The project requires the system to have the following capabilities:

    Constant pressure water supply: ensure stable water pressure on each floor of the community and avoid pressure fluctuations during peak water use periods;

    Energy-saving operation: realize intelligent adjustment of water pump through frequency conversion control to reduce energy consumption;

    Water quality safety: The water tank has a reasonable structure and anti-pollution design to ensure residents’ water hygiene;

    Automated control: Realize intelligent monitoring of the entire system, reduce manual operations, and improve management efficiency.

C. Core technical solutions

This project adopts a variable frequency constant pressure water supply system, combined with an intelligent control platform. The main configuration is as follows:

1. water tank system

    Combined stainless steel water tank (specifications:10m×3m×2.5m, with partition)

      The volume is sufficient to meet the daily water needs of the community;

        Internal partitions are installed to optimize the water flow state, reduce dead water areas, and facilitate water quality maintenance;

        The material is food-grade stainless steel, which complies with drinking water hygiene standards.

2. Pump and valve system

    Complete valve set for water inlet (model:PHB-50-3): Equipped with filtration, voltage stabilization, and anti-backflow functions to ensure the safety of water inflow;

    Outlet complete valve set (model:PHL-50-3): Integrated check, adjustment, pressure relief and other functions to ensure stable water output;

    Diaphragm pressure tank (model:SQL800×1.0MPa): It plays the role of buffering pressure fluctuations, reducing frequent starts and stops of water pumps, and extending the life of the equipment.

3. Intelligent control system

    fullABBFrequency conversion control cabinet (model:PK-3H/4.0-Q）：

        carryABBHigh-performance frequency converter realizes soft start and stop of water pump and stepless speed regulation;

        Automatically adjust the running frequency of the water pump according to real-time water consumption, resulting in significant energy saving;

    PLCControl cabinet:

        Integrated automation program supports multi-pump cycle operation, automatic fault switching, remote monitoring and other functions;

        It has real-time collection and alarm functions for water level, pressure, current and other parameters.

4. Supporting equipment

    Water pump units, cables, pipe accessories, etc. are selected and installed in accordance with national specifications to ensure the overall compatibility and reliability of the system.

D. Highlights of Project Implementation

    Energy efficient and efficient: PassedABBThe frequency conversion system enables the water pump to operate on demand, and the comprehensive energy saving rate is expected to reach25%-30%；

    Intelligent monitoring:PLCThe system supports remote operation and data upload, and properties can check the operating status in real time through the terminal;

    Hygiene protection: water tank with partition design+Fully closed system, effectively reducing the risk of secondary pollution of water quality;

    Stable and reliable: the pressure tank and the valve group work together to significantly reduce the water hammer effect, and the system operates smoothly and quietly;

    Convenient maintenance: modular design, key equipment has reserved maintenance interfaces, reducing later maintenance costs.

E. Project results

    After the system was delivered, it was tested and found that the water supply pressure was stable within the set range, fully satisfying the needs of the community.24Hourly demand for water;

    The operating noise of the equipment is lower than the national standard and will not cause any disturbance to residents;

    It successfully passed the joint acceptance of the construction unit, property management and related departments, and was highly praised for its “efficient operation, intelligent control, and convenient maintenance”;

    It has been put into daily use with good feedback from users and the workload of property management has been greatly reduced.

F. Summary

Wuyi Baihe Xinyuan life pump house project integrates advanced frequency conversion control, intelligentPLCManagement and sanitary water tank system, creating an energy-saving, safe and smart urban residential water supply solution. The project fully reflects the comprehensive value of efficient design, reliable equipment, and intelligent control in modern building supporting projects, and provides a reference example for the construction of pump stations in similar communities.
