If someone asks you the role of the air compressor air tank, do you always feel that it is difficult to express in words, or you can only understand it, but not in words. how could be! That's because we generally only know one thing and don't know the other, and there are many functions of gas storage tanks!

Let’s first introduce the basic common sense functions: store air to meet the sudden and instantaneous increase in gas consumption of gas-using equipment; eliminate the pulsation of air flow in the pipeline; initially cool the air and let part of the liquid water precipitate. Therefore, the air storage tank should be drained regularly; it can ensure the automatic shutdown of the air compressor. When the air storage tank is full of air under the set pressure, the air compressor will automatically stop, so as not to let the air compressor keep running and waste electricity.

In theory, the bigger the air tank, the better, which can reduce the number of frequent starts of the air compressor. The star-delta start is a power frequency start, and the instantaneous current of the motor starting is about 7 times the rated current. Frequent start-up will cause great damage to the electrical parts of the air compressor, reducing the life of the electrical parts, and at the same time comparing the impact on the power grid. large, affecting the normal use of other electrical equipment. The variable frequency air compressor is a soft start, the starting current is about 2 times the rated current, and the impact is not very large.

Can the air storage tank of the screw air compressor not be used? The air storage tank at the outlet of the air compressor can not only play the role of stabilizing the outlet pressure and buffering, but also has an important role that ordinary users will not notice, that is, preventing During the shutdown of the air compressor, the compressed air pipeline returned liquid for some reason and poured back into the air compressor, which was damaged. If the air storage tank is removed, the inverted U-bend design should be used to achieve the same effect when designing the pipeline.

In addition, the air storage tank maintains the pipe network pressure of the compressed air system without large fluctuations. Since the air consumption at the end of the compressed air system generally cannot be stable at all times, the air storage tank should be used to balance the stability of the system pressure and reduce the frequent loading and unloading of the air compressor.

Another function is to cool the dried compressed air again to reduce the moisture content in the compressed air. For individual compressed air systems, such as the air compressor with a large displacement (such as a centrifugal air compressor), the volume of the system pipe network is also relatively large (the pipe diameter is large and long) and the gas consumption is relatively stable, it is also necessary to Can not be equipped with gas tank. But the general compressed air system needs to be equipped with an air storage tank.

There is no place to store compressed air inside the air compressor. Once the compressed air is generated, it must be used up. This way of working is not ideal. With an air storage tank, you can first pump the compressed air into the air storage tank to a certain pressure, and then When the air pressure drops to a certain level, the compressor is restarted, which is more ideal both in terms of energy utilization and compressed air quality. So no gas tank will do.

In addition, for equipment that requires a small amount of compressed air and is used infrequently, the air compressor does not need an air storage tank. However, considering the stable performance of the air compressor, the constant pressure and quality of the compressed air, it is best to use an air storage tank. After completing Yunji's answers to netizens, contact the air storage tank from different angles of the air compressor.

1 Air compressor action

Since the action range of the air compressor is relatively large, if the pressure vessel is frequently opened and stopped during work, it will increase the wear of the valve, and on the other hand, it will also make the oil circuit and gas circuit unstable, which will cause the machine to not work properly. Stability, but if a gas tank is configured, this situation will be relatively reduced.

2 Energy saving effect

The air compressor is frequently started and stopped, so the current of the motor will consume a very large amount, so the state of the air compressor will be no-load. If this state stays for a very long time, it will be Waste a lot of traffic. However, if it is equipped with an air system with an air storage tank, the stability of the air compressor will stop, which can ensure a very stable operation and reduce unnecessary waste of idling energy.

3 Provide a stable air source

Why is the air compressor bound to the air storage tank? If there is an air storage tank in the air compressor system, the output air of the air compressor has a buffer place, the air source can be better maintained at a set value, and the air system can obtain a constant pressure, which is suitable for the use of modern factories. Very necessary.

4 good air quality

The compressed air from the air compressor is first sent to the air storage tank, where the air will stay for a certain period of time, which can precipitate foreign matter such as impurities and moisture in the air, and the temperature of the compressed air is also reduced. Can send out higher quality air. In fact, the function of saving is like a reservoir, the air compressor is a gas source, and the gas storage tank is a pool. The air storage tank of the air compressor can set the air pressure balance within a certain pressure range according to the setting, buffer the fluctuation of the air pressure, and reduce the number of starts of the air compressor. In addition, the air storage tank can also precipitate impurities and moisture in the air. and other functions of foreign bodies.
