1、 Overview:

The amount of water used by users is constantly changing, and situations of insufficient or excessive water supply occur from time to time. The imbalance between water use and supply is mainly reflected in the pressure of water supply, where more water is used and less water is supplied, resulting in lower pressure; If there is less water and more water, the pressure is greater. Maintaining a constant water supply pressure can balance the supply and use of water, with more water supplied when using more and less water supplied when using less, thereby improving the quality of water supply. The constant pressure water supply system is very important for certain industries or special users. For example, in some production processes, if the water supply pressure is insufficient or the water is cut off for a short period of time due to some reasons, it may affect the quality of the product, and in severe cases, it may cause the product to be scrapped and the equipment to be damaged. For example, in the event of a fire, if the water supply pressure is insufficient or there is no water supply, the fire cannot be quickly extinguished, which may cause significant economic losses and casualties. Therefore, adopting a constant pressure water supply system has significant economic and social significance.

2、 Working principle:

The constant pressure water supply energy-saving device adopts the latest computer control technology, using pressure sensor signals and related electrical control signals to control the speed of the water pump motor according to the pressure value of the water supply pipeline, maintaining the pressure at the required pressure value, saving energy that does not need to be consumed normally, thus achieving the goal of energy saving.

3、 Characteristics:

Keep the original control program unchanged, easy to install. Adopting the energy-saving control method of mains power, equipment failure does not affect production. By utilizing electrical control, the original on/off pressure control can be changed to continuous pressure control, resulting in more precise pressure control and smoother water supply pressure. Soft starting device, stepless speed control, can avoid starting current shock. The power factor of the system has been greatly improved, with almost no reactive power loss. Easy to operate, efficient computer control, and almost zero failure rate. Synchronized operation without any adjustment required.

4、 Energy saving effect prediction:

The constant pressure water supply energy-saving device can minimize the power consumption of the water pump. Due to the implementation of stepless speed control, the power consumption of the water pump is closely related to the equipment usage. After retrofitting with energy-saving devices, the energy-saving effect generally reaches 25%.

5、 Application scope:

Waterworks, booster pump rooms, residential areas, hotels, guesthouses and other buildings, enterprise production water, boiler circulating water systems, farmland irrigation systems.
