Current Solving Method&Major Problem for Compressed Air Impurities

First, Filtration

Processing method

Compressed air will be initially treated by filtering particles and impurities, oil droplet, part of liquid water through filter. for traditional cartridge whose bottom is sealed, impurities will be gathered into internal filter. after penetrating into the bottom of filter chamber, impurities are drained out.


Main problem

Solid particles  can not penetrated from the filter cartridge, it can be attached to inner wall of filter element, which will increase air resistance, at the same time penetrating water droplet and oil droplet may be taken away by compressed air again.


Second, refrigeration

Processing method

Mainly use refrigerated dryer to cool the air, then decrease temperature of water content saturation from hot to cold. some water will be condensed into liquid water , and then drained out.


Main problem

The refrigerant evaporation temperature shouldn't be less than 2℃ due to the limit of refrigerated dryer's working principle and structure.  otherwise the pipework will be blocked for freezing, while heat transfer efficiency and water separator efficiency determine that actual dew point of outlet will rarely reach evaporator's settings value. it should increase refrigerant compressor power if you want to get lower dew point, which will not only increase purchasing cost of dryer, but also increase its operation cost. Currently, most of measured dew point is  20~35℃ in practice and it has plenty of liquid water.


Third, adsorption

Processing method

Dryer absorbed water from compressed air in high pressure and desorption and regeneration in low pressure,then recycling by PSA principle of water adsorption characteristics,after that get dried compressed air, general pressure dew point can reach -20℃~-70℃.



Main problem


Currently, the twin towers or a combinational twin tower adsorption dryer is mainly used at domestic market. its major problem is that desiccant is difficult to fill up closely. it is easy to form tunnel effect, leading to substandard performance, and higher energy consumption, it is also difficult to proceed second replacement&filling.

Modern Planning in the Field of Compressed Air

图片
In the past, people only consider the initial investment and operating energy costs such as some simple economic factors, they often overlook the influence pollutants in the compressed air for system when established a compressed air system , thus ignoring the compressed air quality (it can not reach standard will bring huge invisible waste for enterprises), and these losses are often much higher than the high quality purchase and operating costs of purification equipment. Perhaps many companies believe that compressed air equipment just little impact when select ordinary one, but what will actually appear on us? In the 1980s, the industry lagged far behind today, the developed countries put forward ISO8573 standards for the purity of compressed air as for different gas equipment, while it failed to supply the gas equipment standard of compressed air, which caused serious impact, such as shorten the service life, decrease accuracy, increase failure rate, poor quality, and the safet

The Importance of Brand Awareness

图片
Brand is an invisible asset for the enterprise, it’s also the most valuable wealth. in the rapid development of the modern life, the difference become shrinking for product performance, quality, sales service from different enterprises, so the brand will become the main factor to choose products for consumer. "Stupid businessmen sell products, smart businessmen sell brand" This sentence fully illustrates the importance of the brand for the enterprise . therefore, companies should have enough brand awareness, and strive to run the business brand. it is the core content of the product, and brand awareness isn’t all other means of marketing, such as Atlas, Ingersoll Rand, Sullair, Kobelco, etc. these enterprises prefer to brand recognition rather than products identification , and it’s also become the only element of market choice. Brand not only refers to the product quality, but also includes the appearance, technology, function, utility and others, it need long-term accumulat

“Throw a sprat to catch a herring" to get the maximum benefit in a short period

There is a question, why do we establish business? Companies just considering saving cost regardless of construction of enterprises, but it real should need the cost of consumption. later hear a manager says to the subordinate, " I have to find ways to earn back for company spent every penny", perhaps this is a lot of top management staff thought, which is good point for a top manager, then we will be reach the business target to obtain the greatest benefits in a short period.  It is not so easy to realize how to get the maximum benefit in a short period. such as a lot of leading brands seem to be impeccable, while the leading brand's business is far less flexible than some small businesses for imbalanced development of different regional market, much longer product line, and imbalanced development in different products. it is difficult to develop appropriate products and marketing strategy according to local conditions due to consider the national market.
