Product Overview

The Smart Variable Frequency Constant Pressure Water Supply Equipment is a new type of energy-saving water supply device. The Variable Frequency Constant Pressure Water Supply Equipment utilizes modern microcomputer control technology, combining a variable frequency speed regulator with an electric motor and pump to create an integrated mechanical and electrical energy-saving water supply unit. This equipment sets the water pressure at the pump outlet (or the user's water flow rate) as a parameter, and uses a microcomputer to automatically control the output frequency of the variable frequency inverter to adjust the speed of the pump motor, achieving closed-loop regulation of the water pressure in the user's pipeline network, ensuring the water supply system remains automatically constant at the set pressure value: when water usage increases, the frequency rises, and the pump speed increases; when water usage decreases, the frequency drops, and the pump speed slows down. This ensures that the entire user pipeline network always has sufficient water pressure (matching the user's set pressure) and flow (which changes according to the user's water usage).

● Model Significance

Product Features

1. Energy-saving: More efficient than constant-speed pump water supply, saving electricity.

2. High degree of automation, comprehensive features, and easy to use and manage.

3. Equipped with automatic patrol inspection: the patrol interval can be set at will, and either variable frequency or industrial frequency patrol mode can be selected. This eliminates the risk of pump rusting or damage due to prolonged inactivity.

4. Equipped with an automatic shutdown function for low water level in tanks or pools: The equipment will automatically shut down when the water level reaches the set low level to protect the equipment. The pump to restore normal water level can automatically start and resume operation.

5. Fault Self-Diagnosis Function: Automatically detects inverter faults and determines issues such as short-circuit damage to sensors.

6. Pressure Pre-set Function: Dual constant pressure control is highly convenient for both residential and industrial fire protection systems. During normal water supply, the pipeline system is set to a predetermined pressure. In case of fire, the fire protection pipeline system automatically switches to pressure operation.

7. Reliable operation with comprehensive protection features. Equipped with multiple protection functions including phase loss, short circuit, overcurrent, overload, overvoltage, undervoltage, overheating, and stall, which significantly enhance the reliability of the equipment. Night auxiliary pump pressure maintenance avoids noise generated by the main pump during nighttime operation, and also reduces electrical energy waste and noise.
