Product Overview

The Intelligent Variable Frequency Constant Pressure Water Supply Equipment is a new type of energy-saving water supply device. This 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. The Variable Frequency Constant Pressure Water Supply Equipment sets the water pressure at the pump outlet (or the user's water flow rate) as the control parameter. It regulates the speed of the pump motor by automatically controlling the output frequency of the variable frequency inverter, achieving closed-loop regulation of the user's pipeline water pressure. This maintains the water supply system at a constant pressure value as set: 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 network 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: Water supply by constant-speed pump saves electricity.

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

3. Features automatic inspection function: Inspection interval can be set at will, with options for variable frequency or industrial frequency inspection methods. Prevents pump from rusting or being damaged due to long-term non-operation.

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, 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 is set to the designated pressure. In the event of a fire, the fire protection pipeline system automatically switches to pressure operation.

7. Reliable operation with comprehensive protection features. Equipped with multiple protections such as 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.
