Common Sense of Purification Equipment


Air supply system


Gas source system consists of generates, processes and stores compressed air equipment. A typical air supply system consists of following components: air compressors, rear coolers, filters (including pre-filter, oil-water separator, pipeline filter, degreasing filter, activated carbon filter, sterile filter etc.), gas storage tank, dryer (refrigeration and adsorption), automatic drainage&sewage device and gas pipeline, pipeline valves, instruments and so on. It combines into a complete air supply system according to the different needs of the technological process.

Why must process air supply system?


Compressed air (output from air compressor) contains a large number of harmful impurities, it will cause great harm to the gas source system if without appropriate method to remove these impurities:

1. Degenerative lubricating oil will make rubber, plastic, sealing material deterioration, and then plug holes, resulting in valve failure, pollute products;

2. moisture and dust will cause rust corrosion of metal devices and pipeline，moving parts stuck or wear, making pneumatic components malfunction and leakage, moisture and dust will plug throttle hole or filter net, moisture freeze cause pipeline freezing or crack in cold areas;

3. The reliability of pneumatic system greatly reduces service life due to poor air quality, resulting in its loss is often much higher than air supply handling device and maintenance costs, so it's absolutely necessary to correctly choose air supply handling system.

What are the criteria for air supply quality?


Different users have different requirements on air supply quality, the national standard GB / T13277-91 of general compressed air quality level (adopting ISO8573 by equivalent) is developed for this purpose. The standard specifies the number of solid particles, moisture and contained oil in the compressed air. In a broader sense, a good air supply should be stable pressure during use, so its pollution is the smallest for surroundings environment.

What kinds of compressed air drying method?


Compressed air can remove water vapor via pressurized, cooled, adsorption and other methods, and then remove liquid water by heating, filtration, mechanical separation and other methods. Wherein refrigerated dryer cools compressed air temperature to remove contained water vapor, while adsorption dryer removes water vapor in the compressed air by adsorption, thus obtaining a relatively dry compressed air.

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.
