Application of Biteman Modular-units Dryer in Automobile Welding





Automobile manufacturing industry is one of the world's major pillar industries. in the fierce market competition, it need to create a personalized car as soon as possible what consumer satisfaction based on market demand. welding is one of the four major processes of automobile manufacturing, it’s one of the important conditions that the rapid & efficient construction of welding production system quickly respond the market demand for the automobile manufacturing industry. Fixture occupies a large proportion in automobile welding line, its design accuracy &progress of manufacturing directly affect automobile’s manufacturing accuracy and production cycle.




In the past, the welding fixture of domestic automobile is designed by traditional manual method. With the gradual implementation and adoption of agile manufacturing, flexible production and integrated manufacturing system of computer, traditional design method can not meet the development requirements of advanced welding production technology, while the emergence of pneumatic technology can improve this situation. In modern manufacturing technology, pneumatic technology plays an increasingly important role, no matter whether in automobile manufacturing, or other manufacturing industry.



Modern pneumatic technology has the advantages of simple structure, low cost, high reliability and long service life. This is also in line with engineering concept with high standard and high quality for modern manufacturing enterprises, which are constantly pursuing high automation rate, low production cost and stable operation of equipment. it greatly improving the manufacturing efficiency and product quality due to wide applications of the pneumatic technology in a variety of automated production equipment and production lines.




However, the attendant problems are also to be solved. the power of pneumatic technology is closely related to air supply, while the air supply is compressed air, compressed air final connection with gas equipment through air compressor, gas storage tank, dryer (adsorption / refrigeration), filter, which is essential to source of power to ensure normal work of pneumatic system during this process. It bring various degrees of damage to gas equipment of back-end connection, and bring different levels loss to enterprise compressed air purification if not so clean and dry to purify compressed air.


It will damage the pneumatic components, increase purchase cost of spare parts, increase maintenance costs, increase the loss of downtime, increase production costs, increase product defect rate(increase equipment cost), long-term impact of water content, shorten service life, increase business costs, and other intangible and tangible losses due to substandard gas supply.




Many losses has brought unpredictable damage to the enterprise, while its urgent problem is whether meet standard of gas source. energy consumption of refrigeration dryer reach above 10%, pressure dew point is only +3 ℃ or so, gas source basically can’t meet standard compared with most gas equipment; the traditional twin tower adsorption dryer can achieve -70 ℃ pressure dew point what gas equipment require , but its energy consumption reach 25% or so, it means that the gas supply meet standard but large energy consumption, then enterprise can not afford it, so meeting standard of air supply is much less in a certain energy consumption. compared with above types dryers, biteman modular-units dryer —pressure dew point of heat-less model can reach -70 ℃, energy consumption is only about 6%, while energy consumption of micro heat model is only about 2% , air supply can meet standard, energy consumption is also relatively small.





In the actual application, BYD (Changsha, Xi'an, Shenzhen), Chongqing Changan Automobile, Wuling Automobile, Dongfeng Liuzhou Automobile and many other automobile manufacturers have been significantly improved and resolved after using biteman modular-units dryer for pneumatic equipment, energy consumption, comprehensive cost, product defect rate and other issues.




Stamping, welding, painting, assembly is the four major automobile manufacturing process, while entire automobile manufacturing process quite rely on compressed air , then it becomes particularly important for compressed air quality. biteman can guarantee both the reduction of comprehensive cost and high production efficiency as for compressed air purification equipment.




Compressed air purification equipment should be carefully chosen according to the actual situation for an enterprise , biteman modular-units dryer is only much more advantages.

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

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

Analysis on Advantages and Disadvantages of Compressed Air Dryer

They are common compressed air drying equipment : refrigerated dryer and adsorption dryer , enterprises need to understand the advantages and disadvantages of refrigerated dryer and adsorption dryer first during selecting compressed air dryer, so that they can choose the appropriate production Dryer equipment. Refrigerated Dryer Advantage: 1. Don’t need to regularly add &replace the adsorbent; 2. Without compressed air consumption, but there are power consumption; 3. Low noise running; 4. Without valve wear . Disadvantages: 1. The compressed air quality can not meet the production requirements due to technical principles; 2. Outlet quality of instability with liquid water, the pressure dew point is generally above +10 ℃; 3. Adopting refrigerant (Freon) to refrigerate, it will cause serious air pollution; 4. Refrigerant compressor continues to work , the energy consumption is about 6% when the pressure dew point is +10 ℃. 5. Intake temperature has a great impact on pressure d
