Air pressure tank use

Air pressure tanks are widely used in fire water supply systems to stabilize water supply, central air conditioning circulating water stabilizer, domestic water supply, steam supply expansion system, heating system circulating water stabilizer, frequency conversion water supply stabilizer, boiler water supply, pneumatic water supply and other occasions. The diaphragm air pressure tank is an energy storage device composed of a steel shell and a rubber diaphragm inner tank. The rubber diaphragm completely separates the water chamber and the air chamber. The air in the tank is compressed. According to Boyle's gas law, the volume of the gas becomes smaller after being compressed, and the pressure rises to store energy. The expansion of the compressed gas can press the water in the rubber diaphragm out of the tank.

Air pressure tank equipment characteristics

1. The diaphragm structure inside the tank ensures that the water does not contact the tank wall, so there is no rust inside the tank wall, no condensation outside, and the service life is greatly extended.

2. The rubber diaphragm can relax more than 200,000 times, and can be used for a long time after inflation.

3. It can effectively smooth the pressure fluctuation in the water system and reduce the start and stop frequency of the water pump.

4. The diaphragm is food-grade natural rubber. The diaphragm can be used in drinking water systems.

How air pressure tanks work

　　The air pressure tank is an energy storage device composed of a steel shell and a rubber airbag liner. The rubber airbag completely separates the water chamber and the air chamber. When the system pressure is reduced, the pressure of the pre-filled nitrogen squeezes the water in the air bag into the system, slowing down the pressure drop of the system and acting as a voltage stabilizer; when the system pressure rises higher than the pressure of the nitrogen in the air chamber, the water enters the air pressure tank. In the air bag, the air bag expands at this time, absorbs the pressure, prevents the system pressure from rising sharply, and plays a role in stabilizing the system pressure.

Air pressure tank applicable range

　Air pressure tanks are widely used in central air conditioning, boilers, fire protection, water treatment, water heaters and other fields: central air conditioning circulating water stabilizer, steam supply expansion system stabilizer, heating system circulating water replenishment stabilizer, fire water supply system replenishment stabilizer, Frequency conversion water supply voltage stabilization, boiler water supply, pneumatic water supply and other occasions.

Air pressure tank function

The air pressure tank plays a role in balancing the water volume and pressure in the closed water circulation system, avoiding the frequent opening of the safety valve and the frequent replenishment of the automatic water replenishment valve. In addition, in the water system, the air pressure tank can also reduce the frequent starting of the water pump, and can be used to absorb the water hammer shock caused by the opening and closing of valves and water pumps in the system, as well as a small amount of water at night to make the main pump of the water supply system dormant, thereby reducing the use of water. Electricity, prolong the service life of the water pump, etc. In constant pressure water supply, fire fighting and water treatment, the air pressure tank plays a role in preventing the system pressure from dropping suddenly and stabilizing the system pressure.

Air pressure tank features

　　The airbag structure inside the air pressure tank ensures that the water does not contact the tank wall, so there is no rust inside the air pressure tank wall, no condensation outside the air pressure tank, and the service life is greatly extended. Compared with the traditional expansion tank in refrigeration and HVAC systems, the air pressure tank has many advantages such as easy installation (do not install at a high point), small footprint, no secondary pollution, and long service life.

Air pressure tank installation

1. In the heating system, it is recommended to install the air pressure tank in the place where the water temperature of the system is relatively low. Generally, it is installed at the return water end of the system and the cold water inlet end of the hot water storage tank. The expansion tank of 24L and below can be directly connected to the system pipeline due to its light weight. In order to prevent the pressure tank from entering water and its own weight during operation and causing a large load on the system pipeline, the expansion tank above 24L has its own tripod bracket. Metal hoses can be used to connect the pressure tank to the system, and the pressure tank can be fixed with buried screws. Feet to ensure stability during use.

2. A safety valve should be installed near the air pressure tank to avoid damage to the air pressure tank and other components of the system when the system pressure is abnormal.

3. In the closed circulation system of heating and air conditioning, the air pressure tank cannot be installed at the water outlet of the water pump, which may cause cavitation of the water pump.

4. The pressure tank is delivered from the factory, and the pre-charge pressure has been set, generally 1BAR-4.0BAR. If the user thinks that the pressure is not suitable for the operation of the system, he must use a pressure gauge to test while charging and deflating, or contact the supplier. Charge and deflate without authorization.
