Liming Heavy Industry leads the development of domestic spring cone crusher
2011-07-29
The world's first cone crusher patent was published in 1878, and it was not manufactured until 1898. The United States began to use cone crushers at the end of the 19th century. The spring cone crusher was designed by the Simmons brothers in Milwaukee, USA, hence the name Simmons cone crusher. The aircraft has a history of about a hundred years. Although it has been gradually improved and its structure is becoming more and more perfect, the basic structure has not changed significantly. On the basis of imitating the 2100 and 1650 spring cone crushers of the Soviet Union in 1954, our country designed and produced 1200 spring cone crushers by ourselves. In 1958, a large-scale 2200 spring cone crusher was designed and manufactured. After years of repeated research and practice, we have successively overcome the insufficient spring pressure of the old series, low parts strength and some shortcomings in the structure. The spring cone crushers are now mass-produced in five specifications: 600, 900, 1200, 1750, and 2200. 14 kinds of cavity. Compared with similar crushers in advanced countries, the domestic spring cone crusher still has a gap in quality and performance. In order to catch up with the world's advanced level, the domestic heavy machinery factory introduced the Simmons and rotary disc type of Nordberg Company from the United States. Cone crusher technology, and cooperate to manufacture this series of cone crushers. The basic parameters specified in the new standard for cone crushers are also equivalent to Simmons cone crushers. Therefore, in the future, the spring cone crusher produced in China will be the Simmons crusher, and the old products will be gradually eliminated. The Simmons cone crusher developed and manufactured by Liming Heavy Industry is based on the introduction and absorption of foreign technology, according to customer needs, based on the principle of laminated crushing and the concept of more breaking and less grinding. It is designed and developed with high swing frequency, optimized cavity shape and reasonable Modern high-performance spring cone crusher with stroke in one. Practice has proved that the CS series high-efficiency spring cone crusher has won the trust of global users with its excellent performance, reliable quality and high cost performance. It is an ideal substitute for traditional cone crushers. Liming Heavy Industry leads the development of domestic spring cone crushers with its own brand, technology and strength.

Yesterday, the opening ceremony of the 2011 National Spring Industry New Products, New Technologies and Scientific and Technological Information Exchange Exhibition was held in Dongguan for the first time. Dozens of Chinese and foreign spring manufacturing companies gathered to exchange new technologies. The fair is jointly organized by the National Spring Standardization Technical Committee, the General Parts Product Quality Supervision and Testing Center of the Machinery Industry and other institutions. Well-known spring manufacturing companies and experts from Italy, Japan, and Taiwan attended the meeting. The person in charge of a spring manufacturing company in Dongguan said that there are dozens of spring manufacturing companies in Dongguan, but the level of technology is generally not high. Many companies rely on price competition to survive. Companies that want to grow need to improve their technical level, and the fair is A good platform for technical exchange and learning.

1. Observe the range, that is, the measurement range. As shown in Figure 1, the range of the spring dynamometer is 5N. The measured force must be estimated before use. The measured force cannot exceed the range of the spring dynamometer, otherwise it will be damaged Spring dynamometer. 2. Observe the division value of the spring dynamometer, that is, the value represented between the smallest two scales, and understand the size of the division value, which is conducive to correct reading. As shown in Figure 1, the division value of the spring dynamometer is 0.2N. 3. Observe whether the pointer is pointing to the zero scale line. If it is not, adjust to zero, otherwise the measurement result will be inaccurate. As shown in Figure 2(d), the pointer is below the zero scale value when no force is applied, and the section above the pointer when reading after measurement The value is read in, causing the measurement result to be too large. 4. Before using the spring dynamometer, you should gently pull the hook back and forth several times, the purpose is to see if the spring is in contact with the shell, rubs, and is not flexible.

The air suspension is structurally consistent with the traditional suspension, and is also composed of two major components, a spring and a shock absorber. The difference is that the air suspension spring is equipped with high-pressure air, and the softness and hardness of the spring can be changed according to different needs; the damping of the shock absorber is not static, and it is also adjustable. In other words, the biggest difference between air suspension and traditional suspension is that the characteristics of the suspension are variable, such as height, softness and hardness, etc. can be adjusted according to different road surfaces. So the user has a lot of choice in the suspension characteristics setting. Models equipped with air suspension are mostly set to automatic, comfortable, normal and sports modes. Users can choose different modes according to the road conditions and their preferences. In automatic mode, the on-board computer will adjust the height of the chassis and the softness of the suspension according to the vehicle speed and various dynamic parameters of the body. For example, the chassis will automatically lower at high speeds, and the suspension will become hard during intense driving. Of course, the computer calculates Not necessarily accurate, and the response is not necessarily very positive, so there are several other modes of choice. When the comfort mode is selected, the chassis will be adjusted to the highest level and the suspension will become the softest. This mode is more suitable for driving on potholes and greatly improves driving comfort. If you drive violently at this time, the vehicle will shake more severely and the limit will be relatively low. In the normal mode, the height of the chassis and the hardness of the suspension are in the middle level, which is suitable for good pavement. In the sport mode, the chassis is adjusted to the lowest and the suspension becomes the hardest, suitable for intense driving, and the comfort is inferior to the previous two modes. From our experience, in addition to the sports mode, the chassis height can be manually adjusted in other modes to improve the passing of the vehicle, which is very user-friendly. The emergence of air suspension gives a car multiple personalities and greatly improves road adaptability. It is an equipment that is beneficial to the car. As the air suspension technology is more sophisticated, the cost is high, and the maintenance cost is relatively expensive. Most of the air suspension is equipped on luxury cars, such as Mercedes-Benz S-class, Porsche Cayenne, Audi Q7, etc., but with the popularity of technology and cost Decrease, the current equipment has a downward trend, and the current minimum has been "decentralized" to some luxury brand models of around 500,000 yuan.

How to maintain a spring mattress
2011-07-29
As long as they are used properly, high-quality spring mattresses are generally strong and durable and can last a long time. But you need to pay attention to: 1. Avoid excessive deformation of the mattress during transportation. Do not bend or fold the mattress, and do not directly use ropes to forcefully bind it.  2. Don't let the mattress be locally stressed, don't stand on the mattress for a long time or let children jump on the mattress, to avoid local compression that may cause fatigue and deformation and affect elasticity. To 3. Do not sit on the edge of the mattress for a long time. To 4. Regularly turn the mattress over and use it. It can be turned upside down or reversed. Generally, the family should change it every 3 months. To 5. In addition to using bed sheets, it is best to put on a mattress cover to prevent the mattress from getting dirty. Or choose a mattress cover for easy removal and washing. To 6. Remove the plastic packaging bag when using it to keep the mattress ventilated. Prevent the mattress from getting wet. Do not expose the mattress to the sun for too long. To 7. Pay attention to placing a cotton felt or bedding on the contact part of the spring mattress with the bed frame to reduce friction and extend the life. To 8. There must be a wooden board under the all-brown mattress, and it cannot be placed in the air.
