How to correctly debug and common troubleshooting and maintenance methods for variable frequency constant pressure water supply equipment
Why is digital integrated full frequency control constant pressure water supply equipment more energy-efficient


The variable frequency constant pressure water supply scheme is a new energy-saving water supply scheme. The variable frequency constant pressure water supply equipment uses DSP control technology and is a high-tech energy-saving water supply device that combines a variable frequency speed controller with a motor and water pump. The variable frequency constant pressure water supply equipment takes the water pressure at the outlet of the water pump (or the user's water flow rate) as the control objective, and adjusts the speed of the water pump motor by automatically controlling the output frequency of the frequency converter through a microcomputer, achieving closed-loop regulation of the user's pipeline water pressure, and automatically stabilizing the water pressure in the water supply system within the set pressure range; When the water consumption increases, the frequency increases, the pump speed accelerates, and the water supply increases; When the water consumption decreases, the frequency decreases, the pump speed slows down, and the water supply is reduced. This ensures that the entire user network has sufficient water pressure (consistent with the pressure set by the user) and water volume (varying with the user's water usage situation) at all times.


Composition of variable frequency constant pressure water supply equipment
The variable frequency constant pressure water supply equipment mainly consists of a water pump unit, a pressure measuring and stabilizing tank, a pressure sensor, a variable frequency control cabinet, etc. It can always maintain the pressure gauge pressure (i.e. the water pressure of the user's pipeline network) equal to the user's set value. Can be used for general living or production water supply. The composition of the water supply system includes:
1. Variable frequency water supply equipment is connected to the municipal pipeline network for constant pressure water supply. When the water supply pressure can meet the needs, all pumps will be automatically shut down. Otherwise, the constant pressure water supply equipment will start and increase the pressure to meet the water requirements.


2. Additional small pumps or pressure tanks can be added to completely eliminate the power consumption of low flow or zero flow water supply. When the water supply pressure is low, the main pump will automatically stop and the small pump or pressure tank will operate.
