Located in the southwest of Shanwei City, Guangdong Province, Mingre Community of Shenzhen-Shantou Special Cooperation Zone is located in the core area of Ebu Advanced Manufacturing Cluster in Shenzhen-Shantou Cooperation Zone. As the first batch of modern communities planned and constructed in the Shenzhen-Shantou Cooperation Zone, it is not only an important carrier for undertaking Shenzhen's industrial transfer, but also a test field for exploring new urbanization construction. The community is adjacent to the traffic artery of Shenzhen-Shantou Avenue in the east and Xiaomo International Logistics Port in the west, making it an important node for the integrated development of industry and city in the Shenzhen-Shantou Cooperation Zone.

    Among the community infrastructure upgrading projects, the open heat pumping station project undertaken by Guangdong Kenfulai Pump Industry is eye-catching. The project adopts the company's self-developed variable frequency constant pressure water supply unit, which realizes 24-hour constant pressure water supply by intelligently adjusting the speed of the water pump, which is more than 30% energy-saving compared with traditional equipment. The KinAI IoT remote control system is equipped with a three-level architecture of "cloud-pipe-end", which supports managers to monitor 16 operating parameters such as water pressure, flow rate, and energy consumption in real time through mobile APP or PC, and can remotely adjust the operation mode of the equipment. When the system detects abnormal pressure in the pipe network, it can automatically start the protection mechanism within 0.5 seconds to effectively prevent pipe burst accidents.

     The commissioning of this smart water supply system marks an important breakthrough in the field of new infrastructure construction in the Shenzhen-Shantou Cooperation Zone. The edge computing technology it adopts not only realizes the rapid processing of local data, but also interacts with the city brain platform in real time through the 5G network, reserving interfaces for the future expansion of functions such as intelligent irrigation and fire linkage. At present, the pumping station has a daily water supply capacity of 8,000 cubic meters, covering a 2.6-square-kilometer planning area of the open heat community, benefiting the first batch of 12 high-tech enterprises and 680 residents, providing a fresh model for the Shenzhen-Shantou Cooperation Zone to build a smart city with "Shenzhen standards and Shenzhen-Shantou characteristics".

KENFLObrandintegratedpressurizedpumpingstationsystem:anefficientsolutionwithmodulardesignandintelligentcontrol

    KENFLO brand integrated pressurized pumping station system is a modern water supply device integrating water supply equipment, intelligent control and IoT management, and its modular structure is deeply integrated with advanced technology, providing an efficient and reliable solution for urban water supply, industrial water and regional pressurization. The following is analyzed from two aspects: core structure and core advantages:

1. Analysis of the core structure of the system

Steel structure pump room

It is made of high-strength galvanized steel, which has the characteristics of corrosion resistance, impact resistance and long life, and can adapt to the complex outdoor environment. The pump room integrates equipment installation base and shock absorption device to effectively reduce operating noise, while the modular design supports rapid installation and later expansion.

Frequency conversion constant pressure water supply equipment

The whole system is made of 304 stainless steel, including pumps, pipelines and valves, to prevent secondary pollution and ensure water quality safety. The core power unit is equipped with 3 vertical multistage centrifugal pumps (2 with 1 standby), with a single pump flow covering 50-150m³/h and a head of up to 200 meters.

Intelligent control unit

Frequency conversion control cabinet: Built-in high-performance vector inverter, combined with pressure sensor to achieve closed-loop control, automatically adjust the operating state of the pump through the PID algorithm to ensure that the pressure of the pipe network is constant (error ± 0.01MPa).

PLC automatic control cabinet: equipped with industrial-grade programmable logic controller, supporting multi-pump linkage, automatic fault switching, rotation operation and other functions, built-in data acquisition module can record equipment operating parameters, and communicate with the upper system through RS485 interface.

KinAI IoT control system: Build a remote monitoring network based on the cloud platform, support 20+ data such as pressure, flow, energy consumption, fault alarm and other real-time viewing on the mobile APP/PC, and realize equipment positioning and intelligent inspection through geofencing technology.

Second, the core advantages of the system

High degree of intelligence

Adaptive operation: The system senses the status of the pipe network in real time through the pressure sensor, and dynamically adjusts the pump speed and start-stop combination to achieve "on-demand water supply";

Remote IoT management: The KinAI system supports remote device status diagnosis, parameter setting, and firmware upgrade, reducing the cost of manual inspection and shortening the fault response time to less than 5 minutes.

In-depth application of data: After the operating data is uploaded to the cloud, AI algorithms can be used to analyze water consumption patterns, optimize scheduling strategies, and generate energy efficiency reports to help save water and energy.

Outstanding reliability

Redundant design: 2. The configuration of 1 standby pump set ensures that the standby pump will automatically cut in within 0.5 seconds when a single pump fails, so as to ensure the continuity of water supply;

Multiple protection mechanism: The PLC system integrates multiple protection functions such as overload, phase loss, dry rotation, overpressure, etc., and cooperates with the high corrosion resistance of stainless steel equipment to extend the overall service life to more than 15 years;

Environmental adaptability: The IP55 protection level of the steel structure pump room can withstand severe climates such as heavy rain and sandstorm, and the wide temperature range operation from -20°C to 50°C meets the needs of the different regions in the north and south.

Energy saving and stability

Compared with the traditional power frequency water supply system, the frequency conversion technology can reduce energy consumption by 30%-50%, and save tens of thousands of yuan in electricity costs annually;

The constant pressure control accuracy is up to ±1%, which completely solves the problem of water pressure instability at the end of high-rise buildings or pipe networks;

The modular design supports rapid deployment, and it only takes 7-10 working days from installation to commissioning and water supply, which greatly shortens the construction period.

Application Scenarios and Values

The system is especially suitable for industrial parks, high-rise residential buildings, rural centralized water supply and other scenarios, and its compact design can save more than 40% of the floor space. Taking the open heat pumping station in the Shenzhen-Shantou Cooperation Zone as an example, the KENFLO pumping station has saved 15% of water per day and reduced the equipment failure rate by 90% through intelligent scheduling and remote operation and maintenance, becoming a benchmark case of smart water construction. In the future, with the continuous upgrade of the KinAI system, the platform can also be expanded to access subsystems such as fire and water supply and water quality monitoring, helping the digital and networked transformation of urban infrastructure.
