Product Overview

The Intelligent Variable Frequency Constant Pressure Water Supply Equipment is a new type of energy-saving water supply equipment. The Variable Frequency Constant Pressure Water Supply Equipment utilizes modern microcomputer control technology, combining a variable frequency speed regulator with an electric motor pump to form 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 the control parameter, and automatically adjusts the output frequency of the variable frequency inverter to regulate the speed of the pump motor, achieving closed-loop regulation of the user's pipeline water pressure, ensuring the water supply system remains stable 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 always has sufficient water pressure (consistent with the user's set pressure) and water volume (which varies according to the user's water usage).

● Model Significance

Product Features

1. Energy-saving: Provides electricity saving compared to constant-speed pump water supply.

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

3. Equipped with automatic inspection function: Inspection intervals can be set at will, with options for variable frequency or industrial frequency inspection methods. This eliminates the risk of pump rusting or damage due to prolonged non-operation.

4. Equipped with an automatic shutdown feature for low water level in tanks or reservoirs: The equipment will automatically shut down when the water level reaches the preset 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: Capable of automatically detecting inverter faults, such as short-circuit damage to sensors, etc.

6. Pressure Pre-set Function: Dual constant pressure control is extremely convenient for use in both domestic and industrial fire protection systems. During normal water supply, the pipeline system is set to a designated pressure. During fire protection, 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, significantly enhancing the equipment's reliability. Nighttime auxiliary pump maintains pressure to avoid noise from the main pump during nighttime operation, and also helps reduce energy waste and noise.
