Product Overview

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

● Model Significance

Product Features

1. Energy-saving: Water supply by variable-speed pumps saves electricity.

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

3. Features automatic patrol inspection: The patrol interval can be set at will, with options for variable frequency or industrial frequency patrol methods. This avoids the issue of pump rusting or damage due to prolonged non-operation of the pump.

4. Equipped with an automatic shutdown feature 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 up 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, highly convenient for use in both domestic and industrial fire protection systems. During normal water supply, the pipeline system maintains a set pressure. In case of fire, the fire protection pipeline system automatically switches to pressure operation.

7. Reliable operation with comprehensive protection features. Equipped with functions like phase failure, short circuit, overcurrent, overload, overvoltage, undervoltage, overheating, and stall protection, significantly enhancing the equipment's reliability. Nighttime auxiliary pump pressure maintenance avoids noise from the main pump running at night and can reduce electrical energy waste and noise.
