Precautions When Using the Constant Pressure Water Make-up System

The constant pressure water make-up system can be used to ensure that the central air-conditioning system, heating system and water supply system operate under a stable pressure, and realize the functions of automatic water replenishment, automatic exhaust and automatic over-pressure protection. So what are the functions of the constant pressure water make-up system when using it? What to pay attention to, Nanjing Beite will tell you below.

1. The volume of the expansion tank is divided into two parameters: total volume and adjustable volume. The total volume refers to the volume that can be accommodated by the cavity on the inner wall of the tank. The adjustable volume refers to the maximum volume of water that can be replenished under the working condition of the expansion tank. The two parameters should be accurately distinguished for selection.

2. When selecting, you need to determine the working pressure and maximum working pressure of the system.

3. According to the length and size of the installation space, you can contact us to customize various units according to the size.

4. The constant pressure device has two functions: simultaneous absorption of expansion volume and constant pressure of water replenishment, and single water replenishment and constant pressure. When determining the adjustable volume, please refer to the system statistics to accurately determine the data of the adjustable volume.

5. The constant pressure water make-up system can be placed in the basement thermal room or in the mezzanine of the unit. Because the pipes of this device are of small diameter and are easily damaged by freezing, be sure not to install it in the open air, which will affect normal work.

6. The power supply of this kind of equipment needs to be stable and reliable, otherwise technical measures need to be taken.

7. The exhaust pipe and expansion pipe of the constant pressure water make-up system should be connected to the return water main pipe on the suction side of the circulating pump. The exhaust pipe should be connected first according to the direction of water flow, and then the expansion pipe should be connected 2 meters away. That is, the return water flows through the exhaust pipe first. The tracheal node then flows through the expansion tube junction.

8. The connection point of the water supply pipe can be calculated according to the height of the floor. If the water replenishment pressure does not meet the requirements, then you need to consider replacing a suitable water make-up pump.
