Changben Company participated in the 13th China International Foundry Expo

2022-02-22

On March 31st and April 3rd, the Shanghai National Convention and Exhibition Center kicked off. This exhibition ushered in the participation of domestic and foreign foundry industry organizations, scientific research institutions and manufacturers. After more than 13 years of development and growth, the exhibition has become a "world-class foundry fair, the world's largest casting exhibition." This exhibition is an exhibition of achievements in the foundry industry with trans-age significance. The world is attracting the exhibition of new equipment, new products and new technologies. It is also the flagship exhibition that leads the development direction of the foundry industry and promotes the globalization cooperation of the foundry industry. . Quality, efficiency and green are the highlights of this exhibition. This is also the stage where Changben Company is connected with international casting. Changben Company has carefully prepared castings that can highlight the company's casting strength to participate in the exhibition, especially different types of ductile iron castings and gray iron castings. The company also specially printed brochures and hanging axes, and introduced the company's new equipment, new products and new technologies in detail to expand the company's popularity. During the exhibition, the company booth attracted many experts, buyers and foreign traders in the same industry. The company's technical staff received the visitors and sought cooperation opportunities. Changben Company also organized the company's internal squad leader and workshop director to participate in the exhibition, to learn about new technologies and equipment at home and abroad, to learn the advantages of others while discovering their own shortcomings

Basic structure and principle of diesel generator sets

2022-02-22

The advantages of diesel engines are high torque and good economic performance. The working process of a diesel engine has many similarities with that of a gasoline engine. Each working cycle also undergoes four strokes of intake, compression, work, and exhaust. However, since the fuel for diesel engines is diesel, its viscosity is larger than that of gasoline, it is not easy to evaporate, and its auto-ignition temperature is lower than that of gasoline. Therefore, the formation and ignition of combustible mixture are different from those of gasoline engines. The main difference is that the mixture in the cylinder of a diesel engine is compression-ignited rather than ignited. When the diesel engine is working, the air entering the cylinder is air. When the air in the cylinder is compressed to the end point, the temperature can reach 500-700 ° C, and the pressure can reach 40-50 atmospheres. When the piston approaches the top dead center, the fuel injector of the fuel supply system injects fuel into the cylinder combustion chamber at a very high pressure in a very short time. The diesel fuel forms fine oil particles, which are mixed with high-pressure and high-temperature air, and the combustible mixture burns by itself. The violent expansion produces explosive power and pushes the piston down to work. At this time, the temperature can reach 1900 to 2000 ° C, the pressure can reach 60 to 100 atmospheres, and the generated torque is very large, so the diesel engine is widely used in large diesel equipment.
