On April 1, 2011, Kumho (China) Tire announced the recall, and Kumho became the first tire recall company in China. Up to now, 270,386 tires have been replaced. These include products that are not within the scope of the recall, but that are hidden due to positioning or wear. In addition, Kumho also implements free testing services for all products, and sets up official inspection sites in large and medium-sized cities throughout the country. The time for free testing is extended to December 30, during which an integrated test of 539,923 vehicles has been completed. It is reported that the replaced tire will be treated by thermal decomposition or smashing so that it will no longer retain the prototype of the tire and ensure complete destruction. It is reported that Kumho products extended warranty period, warranty time from 3 years to 5 years. At the same time, we will implement a VIP product protection policy for product protection systems sold during the period from August 1, 2011 to March 15, 2012, and implement special safeguard policies for products sold from August 1, 2011 to December 31, 2011. With the protection system, Kumho also launched a large-scale promotional raffle campaign for consumers, with “Hao Li sent members, good rewards and rejoicingâ€. A total of 5032 lucky users were created throughout the country, sharing prizes worth a total of RMB 3.2 million. In order to further meet the needs of consumers, Kumho intensified the KU28, extended the sidewall cord cover in the structure, effectively strengthened the sidewall strength and safety performance, and brought the dragon's design inspiration into the sidewall in appearance. Line design. It is reported that the recall of Kumho Lake has prompted relevant policies to be further improved. China’s 20-year-long “Some Regulations on Meridian Tire Technology†will be revised, and the introduction of the “Regulations on the Supervision and Recall of Automobile Products†has also played a role in promoting the development of the industry. Widespread use of tires and maintenance knowledge. The dryer is a kind of mechanical equipment that uses heat energy to reduce the moisture content of materials. It is used to stop the drying operation of objects and vaporize the moisture (usually moisture or other volatile liquid components) in the materials after heating to obtain solid materials with regular moisture content. The purpose of drying is to meet the requirements of material application or further processing.

The future development of dryers will develop and improve dryers under the conditions of deepening the study of drying mechanism and material drying characteristics, and controlling the operation conditions of different materials; In addition, large-scale, high strength, high economy, and improved compliance with raw materials and quality are the fundamental trends of dryer development. Now let's introduce the function, working principle, classification, operating procedures, selection instructions and cleaning methods of the dryer.
The dryer acts as a refrigeration compressor to suck the low pressure (low temperature) refrigerant in the evaporator into the compressor cylinder. The refrigerant steam is compressed, and the pressure and temperature rise at the same time; The refrigerant steam with high pressure and high temperature is pressed to the condenser. In the condenser, the refrigerant steam with higher temperature and cooling water or air with lower temperature stop heat exchange.
The heat of the refrigerant is taken away by water or air and condensed, and the refrigerant vapor becomes liquid. This local liquid is then sent to the contraction valve, which is throttled into a low temperature and low pressure liquid and enters the evaporator; The low temperature and low pressure refrigerant liquid in the evaporator absorbs the heat of the compressed air and vaporizes (commonly known as "evaporation"), while the compressed air condenses a large amount of liquid water after cooling; The refrigerant steam in the evaporator is sucked away by the compressor.
