However, due to the wide range of applications for refrigeration equipment, the requirements in different fields are also different. With the rapid development of various industries, the requirements for refrigeration equipment are getting higher and higher. From the current point of view, there are still three major shortcomings in China's refrigeration industry.
First, the introduction of foreign advanced technology can not be digested and absorbed in time. In the industrial field, China's refrigeration industry is relatively early in contact with foreign countries. In the mid-1980s, China began to introduce advanced foreign technology and established some joint ventures. But up to now, the technological progress of China's refrigeration industry is far from meeting the needs of other industries, especially some cutting-edge technologies and products are still not developed independently.
After the reform and opening up, a large number of imported products flooded the domestic market, and domestic products were gradually swallowed up by foreign products because of the lack of timely technical updates and development.
Second, the overall quality of the refrigeration industry needs to be improved. Like other domestic industries, the current high-tech workers in the refrigeration industry in China are seriously lacking in fact. Most of the old mechanics have retired, and new skilled workers can't make up. This phenomenon of "green and yellow" has seriously hindered the healthy development of China's refrigeration industry. Therefore, experts suggest that enterprises should hire old technicians with unique skills to let them bring their disciples, through "passing, helping, and bringing", to alleviate the contradiction of the shortage of skilled workers in China.
Third, insufficient investment in technology development funds, serious brain drain, and domestic brands are unknown. As we all know, the compressor is the most critical component of the refrigeration equipment. But when it comes to compressors, the first thing people think of is the American Copeland. Their products are of excellent quality and have been deeply rooted in the market. In order to prove that their products are good and the quality is guaranteed, domestic manufacturers always like to tell users that our products use American Copeland compressors. In the long run, there has been such a concept in the minds of Chinese people. Only the refrigeration equipment using foreign compressors can guarantee the quality of products. And the domestic brand of compressors will be even more "out of the day."
Another product is a refrigeration valve. At present, China's valve products have spread all over the national economy, but it is difficult to establish a domestically produced valve in the refrigeration industry. Most refrigeration equipment manufacturers can hardly tell the manufacturers of domestic refrigeration valves, but these companies do not know Danfoss refrigeration valve products.
The main reason for the above phenomenon is that China has insufficient funds for technology development and lacks funds. “Digestion, absorption and innovation†is an empty talk. In addition, most domestic companies have short-term behaviors, and they like to do things that are effective. However, technology investments that are high in investment and can receive benefits after 5 or 10 years are often not active. In this respect, domestic companies are quite different from foreign companies.
The movement of a tumbler screening machine is usually compared with simple hand screening similar to the [gold washing pan". Basic rotary motion is similar to hand screening. The eccentricity is adjustable from 25 to 40mm, low speed V belt drive is adjustable from 120 to 360rpm. Each product` dwell time can be adjusted in a radial and tangential angle, towards the drive axis.Therefore, establishing the horizontal and throwing three dimensional rolling movement, materials are evenly dispersed on the entire sieve surface from the center to the outer edge, and thus spread towards the axis by spiral movement. Small particles are then finished in the whole sieving process. The horizontal and vertical acceleration are increased with the movement of the particles, and then the particles which are close to mesh size will be successfully separated; The larger particles are transported to the exit, the flow can be controlled by a regulated oriented device at the exit, the oriented device is another factor which controls the dwell time of the materials.
