Air compressor is a kind of power equipment that is extremely important in modern industrial manufacturing and construction. However, in many occasions, a single air compressor cannot be directly applied, but a complete compressor is composed of a dryer, an air storage tank and a pipeline. air system.
Among them, the compressed air storage tank or the air storage tank does not always attract the attention of users due to its low technical cost and low investment, but in fact it is an important part of the compressed air system, and it is even impossible in many working conditions. Missing equipment.
A compressed air storage tank is a simple pressure vessel, with vertical and horizontal types, used to receive compressed air from an air compressor and store it under pressure for use on the gas end. The configuration of the air storage tank in the compressed air system can effectively improve the use efficiency of the system, and its functions can be simply summarized as air storage, voltage stabilization, cooling and purification.
(1) Storage gas volume
Providing temporary storage space for compressed air is the most important role of the air tank. The air compressor is just a device that compresses air, and there is no space for storing air inside itself. Once the compressed air is generated, it must be discharged to the outside, otherwise it will affect the action of the next compression cycle. However, in the normal production process, compressed air is not always required, and once unloaded, when compressed air is needed downstream, there will be a delay in reloading and producing air. However, if an air storage tank is configured, even when the air compressor is not running, the air stored in the tank can still be used for a period of time without delaying the production gas.
Conversely, without an air receiver, over time, frequent loading and unloading would lead to premature failure of switches and other compressor components, excessive motor contactor wear, and even a direct short-circuit to the motor due to damaged winding insulation.
(2) Stable air pressure
Without a gas storage tank, uneven end demand would result in frequent loading and unloading of air compressors to meet changing gas demand. The air compressor is affected by various factors such as temperature, voltage, pipeline, etc., the air pressure is not always stable during operation, especially the reciprocating piston compressor, etc., often produce obvious air pressure fluctuations under some working conditions. Equipped with a gas storage tank, the compressed gas has a buffer space, which can effectively reduce the loading and unloading frequency of the air compressor and the pulsation of the gas in the pipeline, and control the system air pressure within the ideal value range.
(3) Cooling and purification
Air compressor manufacturers know that the process of air being compressed by external force is also a process of converting kinetic energy into potential energy, but a large part of the energy cannot be completely converted, but will be converted into heat energy, which is manifested in the form of an increase in air temperature. Depending on the type of air compressor used, the temperature of the air discharged from the compressor may exceed 100°C. This is not directly available in most cases, and requires post-processing equipment in the compressed air system for processing, one is cooling, and the other is filtration.
The water vapor contained in the atmosphere is sucked into the air compressor for compression along with other air. If it is not removed, the water vapor will condense into liquid water in the pipelines and equipment tools leading to the gas end, which will bring the production system very troublesome. Therefore, the compressed air discharged from the air compressor must be cooled and dried before use. The air tank acts as a storage device. When the air stays in the tank or flows slowly through it, it will naturally cool down over time, and condensate water will be precipitated. The precipitated liquid condensed water and oil vapor condensed into oil, particulate impurities and other mixtures will be collected at the bottom of the tank and discharged.
