Pressure Sensors in Non-Negative Pressure Water Supply Systems

(Summary description) To ensure urban water supply stability and avoid disruptions to residents, regulations prohibit directly installing domestic or industrial water pumps on municipal pipeline networks. This creates the need for non-negative pressure water supply systems, which allow water supply equipment to integrate with municipal pipelines without generating negative pressure or affecting other users. To achieve this, components like flow controllers and sub-cavity stabilized pressure compensation tanks are installed between the water pump inlet and the municipal pipeline. The flow controller continuously monitors the municipal pipeline’s pressure, ensuring negative pressure is avoided while maximizing the existing pressure in the system. A pressure sensor plays a critical role in maintaining system balance and efficiency. How Non-Negative Pressure Water Supply Systems Work When municipal tap water enters a regulating tank at a certain pressure, the air in the stabilized pressure compensation tank is vented via a vacuum eliminator. Once the tank is full, the vacuum eliminator automatically seals. If the municipal tap water meets the required pressure and volume, the system directly supplies water to the network through a bypass check valve. If the municipal pipeline pressure is insufficient, the system activates the pump using signals from a pressure sensor, pressure controller, or electric contact pressure gauge. Variable Frequency Constant Pressure Water Supply System This advanced system consists of a PLC control unit, frequency converter, pump motor, water supply network, storage tank, and pressure sensor. The constant pressure water supply pump station operates multiple pumps, which activate based on water consumption. Key features include: Energy Efficiency: Pumps with lower power requirements operate according to demand, while backup pumps ensure continuous operation during maintenance. Dynamic Control: The PLC adjusts pump activity and motor speed via the frequency converter to handle varying water demands. The Role of Pressure Sensors A pressure sensor is a crucial component in both non-negative pressure and variable frequency water supply systems. Upgrading traditional remote pressure gauges to modern water pressure sensors has resolved challenges such as: System Instability: Conventional gauges often caused fluctuations in water supply. High Maintenance Costs: Frequent replacements of outdated gauges increased operational costs. Pressure sensors ensure stable water pressure and durability, significantly reducing maintenance needs. These sensors detect changes in the water supply network's pressure and transmit real-time signals to the system’s microcomputer. This dynamic control maintains consistent pressure across the network, ensuring user satisfaction. Types of Pressure Sensors Pressure sensors can be categorized based on their output signals and functionality: Pressure Sensor vs. Pressure Transmitter: Sensors without built-in amplifiers vs. transmitters with amplified outputs. General vs. Isolated: General-purpose sensors vs. models designed for corrosive environments. Signal Type: Current-Type: Outputs 4-20mA signals. Voltage-Type: Outputs 0-12V signals.
