The technical superiority of the Intelligent Constant Pressure Water Supply System is defined by its core components and precise engineering specifications. The system typically utilizes a Variable Frequency Drive (VFD) pump set as its heart, which adjusts motor speed to match the exact water demand. This eliminates the inefficiency of traditional pumps that constantly start and stop. Key performance metrics include maintaining pressure within a tight tolerance of ±0.01 MPa and temperature stability of ±1°C. The control panel features a user-friendly digital interface for setting parameters and viewing real-time operational data, including flow rate, pressure, and system status. Constructed with corrosion-resistant materials like stainless steel for wet parts, the system ensures a long service life and minimal maintenance. It is also designed with multiple built-in safety protections, such as dry-run protection, over-current protection, and over-voltage protection, to ensure fail-safe operation. The following tables provide a detailed breakdown of the standard configuration and performance parameters for a typical Intelligent Constant Pressure Water Supply System model.

The system's capabilities can be further understood through its operational features:

  • Auto-Rotation & Standby: The system features a pump alternation function, which automatically rotates the duty pump to ensure even wear and extend the overall lifespan of the pump set. A standby pump automatically activates if the primary pump fails.
  • Sleep Mode: During periods of zero or very low demand, the system enters an energy-saving sleep mode, drastically reducing power consumption until flow is detected again.
  • Data Logging & Communication: Modern systems often include data logging capabilities to track performance and energy usage. They also support communication protocols like Modbus for integration with Building Management Systems (BMS).
  • Compact & Modular Design: Designed for easy installation in space-constrained mechanical rooms, the skid-mounted, modular design simplifies maintenance and potential future expansion.
