Constant pressure water dispenser

Product Details

1、 Product Overview:

The constant pressure water replenishment device is a type of stabilizing water replenishment device, which mainly consists of a stabilizing tank, a water pump, a pressure switch, an intelligent control box, a safety valve, a base, and pipelines; The product is widely used for domestic and fire water supply in multi story or high-rise buildings such as air conditioning, heating systems, residential areas, factories, commercial areas, hotels, hospitals, military facilities, etc. It can replace traditional expansion water tanks, reduce the number of times the main system circulation pump is started, adjust the water pressure and volume of the system, and is easy to achieve automatic water replenishment.

2、 Working principle:

The constant pressure water replenishment device operates by utilizing the expandability of gas. After the installation of the constant pressure water replenishment device, the upper limit P2 (pump stop pressure), lower limit P1 (pump start pressure), and pressure values of the pressure switch can be set (specific setting values can be set according to customer needs). After the above work is completed, the power can be turned on to start water supply. Start the water pump and fill the building pipeline network and pressure stabilizing tank with water. As water is an incompressible liquid, the volume of the water chamber continues to expand as the water volume increases. The bag shaped diaphragm continuously expands outward, squeezing the air chamber and causing its volume to continuously decrease. The pressure inside the tank also increases continuously. When the set maximum pressure P2 is reached, the water pump automatically stops. Due to the decrease in the volume of water in the system, when the system pressure drops, the gas inside the tank expands, pushing the water pressure in the bag back into the system. In this way, the volume of the water chamber continues to shrink, and the sac shaped diaphragm continues to contract. When the water in the water chamber is almost used up, the pressure inside the tank drops to the design pressure P1. At this time, the pressure switch touches the set minimum pressure contact, and the water pump automatically starts, allowing water to fill the pipe network and water chamber again. Repeat the above process in this way to ensure the water supply of the water supply system. The above operation process is achieved by the pressure switch controlling the start and stop of the water pump through the electrical control box.

3、 Product features:

1) One inflation can maintain long-term use, and users do not need to set up additional inflation equipment.

2) The tank is a closed device, and the gas and water do not come into contact, which can fully ensure that the water quality is not contaminated by external factors.

3) Small footprint, investment savings, fast installation, simple operation, and convenient maintenance.

4) Eliminating the need for high-level water tanks for living and firefighting on the roof of buildings is beneficial for structural seismic resistance and building aesthetics; It can reduce water flow noise, cavitation, pipeline resistance, and water hammer effects, avoiding the phenomenon of inaccurate measurement due to water meter idling.

5) Flexible and adaptable, the installation location is not limited by height, making it easy to renovate, expand, and relocate.

6) Automatic control, easy to use, and reliable operation.

7) Can ensure the water supply pressure required for water points and fire hydrants, ensuring safe and reliable water supply.
