non-negative pressure water supply equipment
1、 Overview
The YLY-WFY type non negative pressure water supply equipment fully utilizes the original pressure of the tap water pipeline network, and achieves pressure superposition on the basis of the original pressure, reducing the selection of secondary pressurization equipment and saving investment. At the same time, it can also save a lot of energy during use, and is currently the most advanced and new type of secondary water supply method.
2、 Equipment features
1. Sanitary and pollution-free 4. Low investment, low operating costs 7. High degree of automation
2. No energy waste 5, simple installation
3. Equipment management is convenient, simple, and occupies a small areaWater supply equipment
3、 Application Fields
The pipeline boosting equipment is suitable for residential areas, factories, hospitals, offices, and other places that require secondary boosting water supply due to insufficient incoming water pressure; Intermediate booster pump stations for various water sources; Various pressurized circulation systems.

4、 Working principle
By setting the water supply pressure required by the user through a microcomputer, when the user's water consumption increases and the microcomputer detects that the pressure of tap water is lower than the user's required water pressure, the microcomputer will automatically control the frequency converter to start, and the pipeline pressure regulation system will work until the pipeline pressure increases to the user's required water pressure. The microcomputer controls the frequency converter to output a constant frequency, and the pipeline pressure regulation system operates at a constant pressure to ensure that the user's water pressure is constant.
When the user's water consumption decreases, the pressure of tap water gradually returns to the water pressure required by the user. The frequency output of the microcomputer controlled frequency converter gradually decreases until the booster pump stops running. The system fully utilizes the original pressure of tap water while ensuring the stability of the user's water supply pressure.Disinfection equipment
