Product Description

Product Description

Constant pressure water supply equipment is an intelligent water supply device that achieves stable pipeline pressure through variable frequency speed regulation technology and closed-loop control system. It mainly consists of a water pump group, pressure sensors, variable frequency drives, and PLC controllers. Its working principle is to monitor the pressure of the pipeline network in real time, compare the detection signal with the set value, and use PID algorithm to dynamically adjust the speed or start stop quantity of the water pump, so as to maintain a constant output pressure when the water consumption changes. It has the advantages of energy saving of 20% -40%, small footprint, and automated operation, and is widely used in high-rise buildings, industrial production, municipal water supply and other fields

Core components
Component	Function Description
Water Pump Set	Includes 2-4 main pumps (including backup pumps) and auxiliary pumps, with flow regulation achieved through variable frequency speed regulation
Pressure sensor/transmitter	Real time monitoring of pipeline pressure, converted into standard electrical signals (such as 4-20mA) and fed back to the controller
Frequency converter	Receive PID regulation signals, adjust motor speed to control water pressure, and have soft start function to prevent water hammer effect
Plc controller	Integrate logic control and communication modules to achieve pressure data analysis, pump scheduling, and human-computer interaction

Application Scenarios

Municipal water supply: secondary pressurization of high-rise buildings, pressure compensation for old pipeline networks;
Industrial production: cooling water supply for chemical processes, pure water transportation for electronic manufacturing;
Public facilities: fire water supply system, agricultural irrigation pipeline network;
Special fields: oil field water injection, geothermal reinjection and other scenarios that require precise pressure control.

Technical Advantages

Energy saving and efficient: Compared with traditional valve regulation, variable frequency speed control can save energy by 20% -40%, avoiding unnecessary energy waste;
Stable and reliable: Through real-time closed-loop control, the pressure fluctuation range can be controlled within ± 0.01MPa;
Extend equipment lifespan: Soft start reduces mechanical impact, and cyclic switching strategy balances pump wear;
Intelligent compatibility: Supports protocols such as Modbus and Profinet, and can integrate with the Internet of Things to achieve remote monitoring
