Panda Group Leads Innovation and Development in Variable Frequency Water Supply Systems

With the continuous advancement of technology, high-tech, environmentally friendly, and energy-saving products have become mainstream in the field of water supply and drainage, as well as heating and ventilation. As one of the leaders in this field and an important partner of Shanghai Songjiang Group which excels in manufacturing rubber bellows and spring isolators, Panda Group has been committed to promoting technological innovation and product development. Among them, variable frequency technology, as an important technical means, has been increasingly adopted by industry professionals, achieving significant results in reducing operating costs and environmental noise. Panda Group, as the developer and user of variable frequency water supply systems, has considerable research and development and application experience.

Panda Group continuously promotes technological innovation in variable frequency variable speed constant pressure systems. The latest development, HLS variable frequency complete water supply equipment, is equipped with intelligent variable frequency pumps, ensuring constant outlet pressure regardless of peak or off-peak water usage. Its control system is advanced, utilizing fuzzy control principles, precise and fast PID calculation functions, as well as configuration communication and other state-of-the-art control technologies, with a touch-screen human-machine interface. Using MODBUS/RTU communication protocol, PLC communicates with multiple frequency converters, and establishes a powerful remote and mobile wireless cluster monitoring system and intelligent microcomputer automatic processing software system, with high control accuracy and reliability.

The pictures below illustrates the specific installation and application of rubber expansion joints produced by Shanghai Songjiang Group in the variable frequency water supply system developed by Panda Group.

The system operates reliably, with functions such as variable frequency operation, constant outlet pressure, pump redundancy, timed switching, automatic fault handling, and alarm systems. At the same time, the system adopts advanced pressure transmission systems and digital signal transmission conversion systems to ensure accurate and error-free data collection and transmission. The equipment has a high degree of automation, achieving automatic operation and unattended operation, with simple and user-friendly operation. The full Chinese touch-screen human-machine interface makes operation more convenient and simpler. Advanced dynamic display technology and design concepts allow users to intuitively and clearly understand various operational statuses, fault statuses, and historical technical data of the equipment, improving the visualization level and user experience of the equipment.”
