YQG series domestic water supply equipment is divided into:

1、 Variable frequency speed regulation water supply equipment for daily life;

2、 Domestic air pressure water supply equipment:
1、 Overview of Variable Frequency Speed Control Water Supply Equipment Products:
YQG... life specific type, fire (life) shared type, variable frequency speed regulation, constant pressure variable water supply equipment. The system is efficient, energy-saving, and technologically advanced. It adopts an internationally advanced AC frequency converter, which automatically controls the power frequency and voltage of the AC motor of the water pump through a microcomputer according to the changes in water consumption in the water supply network, thereby achieving automatic adjustment of the water supply volume, automatic selection of the number of water pumps to start and operate, ensuring the water supply pressure in the network, and significantly saving electricity and water, achieving the most reasonable and energy-saving optimization system.
=Product performance and features:
1. Due to the system's ability to adjust the water pump speed according to the user's water demand at any time, thereby changing the water supply volume and ensuring water quality, the energy-saving effect of water pump speed regulation operation is very significant.
2. The soft start of the water pump completely avoids the strong starting current.
3. Fully automatic control, complete protection functions, automatic fault diagnosis, with multiple protection functions such as overvoltage, overcurrent, and short circuit of input power supply.
4. Adopting internationally advanced imported variable frequency drive (WVF) ABB brand and industrial microcomputer (PLC) Omron with reliable performance.
5. Water pump control method: cyclic soft start, which means that both motors have soft start. The motor that starts running first will stop working, and the water pump will be switched at regular intervals, greatly extending the service life of the equipment.
6. Various additional functions can be added according to the user's special requirements, such as timed start stop equipment, liquid level control, etc.
Scope of application:
1. The energy-saving effect is particularly significant for urban tap water and gas stations with a daily water supply of less than 100000 cubic meters.
2. Domestic water supply for residential areas, hotels, and other large public buildings.
3. Production (living) water supply for large, medium and small industrial and mining enterprises.
4. Fire water supply systems for residential areas, hotels, large public buildings, and various industrial and mining enterprises.
5. Constant pressure (variable pressure) cooling water supply and heating, air conditioning, hot and cold water circulation water supply systems, and other infusion systems for industrial and mining enterprises.
6. Sewage pumping station, sewage lifting and water supply system in water treatment.
7. Agricultural irrigation and drainage, garden spraying, water features, and music fountain systems.
