The fire protection constant-pressure water supply unit is considered one of the earliest introduced domestic water supply and drainage equipment, widely used in the overseas HVAC market as early as the 1970s. Its principle of operation combines the functions of both a booster pump and a water supply pump. When it comes to water supply and drainage equipment, the development overseas has been relatively rapid. Several years ago, the Fillough constant-pressure water supply technology was introduced from the United States, and now it has continuously expanded and improved, developing more product categories, and quickly sparked a surge in the development of energy-saving and environmentally friendly equipment in China.
According to information, in the HVAC industry, the investment in water supply and drainage equipment typically accounts for 10% of the total system investment. Therefore, for industries like ours that produce waterway accessories, it's crucial to focus on producing more energy-efficient and environmentally friendly products. The fire suppression constant-pressure water-supply device, due to its energy-saving advantages, is considered a major "candidate." Energy conservation and environmental protection will also remain an eternal topic for industry development in the future.
What is a fire suppression pressure maintenance water supply device?
Definition: A fire suppression constant pressure water supply device is a combined multi-functional hydraulic regulating device selected based on the flow and head of the water supply pump, also known as a hydraulic pressure stabilization unit.
Composition: Consists of a series of components including a voltage stabilizing pump, a pressure relief tank, a pressure sensor, an electric control cabinet, and a weighing sensor.
Operating Principle:
1. Pressure Relief and Water Storage Regulation: Upon heating the medium, its volume expands due to the temperature increase, causing the entire system's pressure to rise. When the pressure reaches the set pressure, the pressure relief solenoid valve in the equipment opens, releasing the expanded volume of the medium due to heating into the atmospheric tank, thus maintaining a constant system pressure.
2.补水定压调节 function: After the hot water passes through the heat dissipation equipment and cools down, its temperature decreases and volume shrinks, causing the overall system pressure to drop. When the pressure drops to the set pressure, the water pump will replenish the system from the water stored in the atmospheric pressure tank or other peripheral supply sources through the make-up pump, maintaining the system pressure and temperature.
3. Vacuum Degassing: This process can remove dissolved gases, free gases, and large bubbles from the water in the system or extracted from the system under vacuum conditions, thereby protecting the equipment and ensuring stable operation of the system.
Category: Application Function Category: Divided into types such as small fire extinguishing constant pressure water supply units, bladder-type variable frequency constant pressure water supply units, atmospheric pressure constant pressure water supply units, and constant pressure water supply vacuum degassing units, etc.
By application field: divided into air conditioning constant pressure water replenishment equipment, circulating water constant pressure water replenishment equipment, boiler constant pressure water replenishment equipment, fire protection constant pressure water replenishment equipment, etc.
