High Pressure No Negative Pressure Frequency Conversion Complete Secondary Booster Water Supply System Product Resume
1. Product Overview
This high-pressure non-negative pressure frequency conversion integrated secondary booster water supply system is a new intelligent energy-saving water supply device for municipal pipe network secondary pressurization. It integrates frequency conversion speed regulation, intelligent monitoring and closed-loop protection technologies, fully utilizes residual pressure of municipal water pipe networks, eliminates pipe network negative pressure and water secondary pollution, and solves insufficient and unstable water pressure in high-rise buildings, urban fringe areas and large public buildings. Featuring high integration, full-automatic unattended operation and environmental friendliness, it fully complies with municipal water supply standards.
2. Core Composition
The system adopts integrated modular design with complete supporting parts. All core components adopt high-quality anti-corrosion and pressure-resistant materials for long-term stable operation, and the main configurations are as follows:
Stainless Steel Steady Flow Compensation Tank: Sealed pressure-bearing structure with precision sensors and vacuum suppressors, which dynamically compensates water volume, eliminates municipal pipe network negative pressure and protects pipe network safety.
High-Pressure Frequency Conversion Pump Group: Equipped with IE5 high-efficiency permanent magnet motors and stainless steel multistage booster pumps, supporting multi-pump parallel operation. 25Hz-60Hz stepless frequency conversion realizes adaptive speed regulation with water consumption changes.
Intelligent Frequency Conversion Control Cabinet: Equipped with PLC controller and high-precision pressure acquisition modules, forming a closed-loop control system to realize automatic start-stop, pump switching, fault self-diagnosis and constant pressure regulation.
Auxiliary Supporting System: Complete with stainless steel pipes, valves, backflow prevention, overpressure protection, shock absorption and water quality monitoring modules to ensure full-process safe water supply.
Optional IoT Remote Module: Supports remote monitoring, parameter adjustment, fault alarm and data statistics for intelligent remote equipment management.
3. Working Principle
The system is directly connected to municipal water pipe networks, adopting closed relay boost water supply. High-precision sensors collect real-time pipe network and terminal water pressure data, and the PLC system adjusts pump speed and operating quantity via frequency conversion. It preferentially utilizes municipal residual pressure; automatically boosts pressure during peak water consumption and runs at low frequency/standby during low water consumption to save energy.
The built-in vacuum suppression and steady flow compensation module keeps the municipal pipe network in positive pressure state at all times, completely avoiding negative pressure, backflow and water pollution, realizing stable constant-pressure variable-flow water supply.
4. Core Product Advantages
4.1 No Negative Pressure & Safe Water Supply
Advanced steady flow compensation and vacuum suppression technology thoroughly eliminate municipal pipe network negative pressure, preventing pipe network damage and water backflow. Fully sealed structure avoids external pollution, solves secondary water pollution problems and ensures drinking water safety up to national standards.
4.2 Intelligent Frequency Conversion & Super Energy Saving
The system tracks real-time water consumption for stepless frequency conversion regulation, making full use of municipal residual pressure. It reduces invalid energy consumption with a 30%-50% higher energy-saving rate than traditional fixed-frequency equipment. Alternating pump operation avoids single pump overload and extends equipment service life.
4.3 Stable High-Pressure Water Supply & Wide Adaptability
It achieves high-precision constant-pressure water supply with adjustable pressure, adapting to 10-100m high-rise water supply scenarios. It operates stably under fluctuating water flow and long-distance water delivery conditions, effectively solving high-floor low water pressure and insufficient water volume problems.
4.4 Integrated Installation & Low Maintenance
Integrated modular design realizes on-site quick installation with short construction period and small floor space. The whole machine has simple structure, stable operation and low failure rate, requiring only daily routine inspection, greatly reducing later maintenance cost and workload.
