An expansion tank is a device that stores hot water and is widely used in homes, businesses, and industries. Combined with the hot water heating system, it can help adjust the water pressure of the system, prevent the bursting of the system's water reservoir and pipes, and achieve a more stable, safe and efficient heating effect. I believe many people must have the same doubts as me, why is the appearance of a rectangular water tank designed to have an expanded shape? There must be a certain reason why the water tank is designed like this. Today, the editor of Aike Water Tank will let you know what an expansion water tank is and its function.  Expansion tank The expansion water tank is a container made of welded steel plates, usually round or rectangular, and available in various sizes. It is an important component in the hot water heating system and central air conditioning water system. Its function is to contain and compensate for the expansion and contraction of water in the system. Generally, the expansion water tank is set at the highest point of the system, and is usually connected to the return main pipe near the water suction port of the circulating water pump (central air-conditioning chilled water circulating water pump). The expansion water tank is usually connected to the following pipes, including: expansion pipe, overflow pipe, signal pipe, circulation pipe, drainage pipe, and water replenishment valve. 1.Expansion tube：It transfers the increased volume of water in the system due to heating expansion into the expansion tank (connected to the return water trunk). 2. Overflow pipe：Used to drain excess water above the specified water level in the water tank. When the water expands and the volume of water in the system exceeds the overflow pipe opening, the water will automatically overflow and can generally be connected to a nearby sewer. 3.Signal tube：Used to monitor the water level in the water tank. It can be connected to the sewage basin of the bathroom or toilet on the ground floor of the building, or it can be connected to the boiler room. Generally, it should be connected to a place where people can easily observe to see whether there is water in the expansion tank. 4. Circulation pipe：When the water tank and expansion pipe may freeze, it is used to circulate water (at the center of the bottom of the water tank, connected to the return water trunk). Connect it to the horizontal return main pipe in front of the system's constant pressure point. A distance of 1.5~3m should be maintained between this point and the constant pressure point, so that part of the hot water can slowly flow through the water tank through the expansion pipe and circulation pipe to prevent the water in the tank freezing. 5. Drainage pipe：It is used for cleaning and emptying the water tank, and can be connected to the nearby sewer together with the overflow pipe. 6. Water replenishment valve：It is connected to the float ball in the …Read More

Combined with the hot water heating system, it can help adjust the water pressure of the system, prevent the bursting of the system's water reservoir and pipes, and achieve a more stable, safe and efficient heating effectI believe many people must have the same doubts as me, why is the appearance of a rectangular water tank designed to have an expanded shape? There must be a certain reason why the water tank is designed like this. Today, the editor of Aike Water Tank will let you know what an expansion water tank is and its function.  What is the function of expansion tank? 1、Water holding effect It can also be called the water capacity regulator of the system. The expansion tank is a very important component in the heating system. It can contain the water in the heating system. Because the water in the heating system is easily affected by thermal expansion and contraction, when the hot water heats up, the volume of water in the heating system will increase and expand, and the water pressure in the heating system will also increase. The water tank absorbs excess water from the system due to thermal expansion; When the system cools down and leaks, add water to the system. When the water cools, the volume of water in the heating system will decrease, which will affect the normal operation of the heating system, so an expansion tank needs to be installed. The purpose of installing an expansion tank is to accommodate this excess water expansion, reduce water pressure, and improve the operating efficiency of the heating system. 2、Constant pressure effect The point where the expansion tank is connected to the system is often used as the fixed pressure point or constant pressure point of the system, thereby ensuring that the system does not empty, overflow, or overpressure. The expansion water tank is often connected to the inlet of the water pump. Through the constant pressure function of the expansion water tank, it plays a certain protective role for the water pump. 3. Exhaust function When the heating system leaks or cools down, the water level in the expansion tank will drop, and the water in the expansion tank will be automatically replenished into the heating system. Water generally releases some air during the heating process, and the expansion tank will discharge the air to improve the operating efficiency of the heating system. In addition, the expansion tank can also make the pressure in the heating system more stable and safe. 4、Add chemicals to chemically treat the cooling water. 5、Heating, if a heating device is installed in it, the cooling water can be heated to warm the cylinder. Pay attention to the problem （1）The installation position of the expansion water tank should be considered to prevent the water in the tank from freezing. If the water tank is installed in an unheated room, …Read More

How to maintain and upkeep stainless steel water tanks? Stainless steel water tanks, as equipment for storing domestic water, can only store domestic water (fire water) and cannot store liquids with high acidity and alkalinity such as hydrochloric acid and sulfuric acid. During the use of stainless steel water tanks, do not store other lightweight machinery and equipment at the top of the tank. Do not use hard blocks to randomly tap or paint the surface and pipes of the water tank. If there are any problems, inform the stainless steel water tank manufacturer in a timely manner, contact their technical maintenance personnel, and drain all the water from the tank during maintenance. Do not open the stainless steel water tank inlet cover casually to avoid secondary pollution of water quality. The water tank should be regularly cleaned, disinfected, and sterilized 1-2 times a year.
