Strengthening Social Responsibility 2015 Diesel Engine Show Dongfeng Cummins Re-manufacturing Remanufacturing Technology

The 14th China International Combustion Engine and Components Exhibition was held in Beijing on November 2, 2015. From the first year of 1994, it witnessed the development history of China's internal combustion engine industry for more than 20 years, and it has become the most professional and most influential in the world. The power of the internal combustion engine exhibition.

Dongfeng Cummins 14th China International Engine & Parts Exhibition

At last year's internal-combustion engine exhibition, Dongfeng Cummins has demonstrated its ingenuity in remanufacturing products. At this session of the internal-combustion engine exhibition, Dongfeng Cummins once again pushed "remanufacturing" technology to such an important stage, fully demonstrating that Dongfeng Cummins is in the green environment. Efforts in terms of resource conservation and resources, on the other hand, are also a reliable solution for the consideration of the vital interests of users and provide more choices. This is also an important manifestation of the combination of corporate social responsibility and long-term industrial development.

Cummins ISLe 8.9L Remanufactured Products

The Dongfeng Cummins Engine exhibited a Cummins ISLe 8.9L remanufactured product, which was remanufactured with Dongfeng Cummins cylinders, cylinder heads, connecting rods, turbochargers, and injectors. We can see that the remanufactured products are basically the same as the original spare parts and are all genuine spare parts produced according to Cummins remanufacturing technology. It is understood that these parts are in full compliance with the original quality standards and specifications, and have the same product quality as the new ones. performance.

"Recycling" has always been one of the core concepts of environmental protection. Remanufacturing is a high-level form of renewable resource use. It uses advanced cleaning technology, repair technology and surface treatment technology to achieve the same performance of used components as new products. It not only makes full use of the secondary resources contained in used products, reduces the exploitation of primary resources, but also facilitates maintenance and reduces cost.

Domestic users have doubts about the "reliability" of remanufactured engines. This is also the main reason why remanufactured engines are difficult to develop rapidly. However, the actual use of remanufactured engines is not the case. Currently, Dongfeng Cummins's remanufactured products are mainly targeted. It is the old machine replacement market for users of large-scale transportation and logistics enterprises. It uses the model of “new machine + price difference” in exchange for “remanufacturing” or “old machine + price difference” in exchange for a new engine. On the one hand, it will save users' procurement costs; on the other hand, “remanufacturing” will foster a stable and gradually expanding end-user group. According to Dongfeng Cummins professional technicians, the remanufactured engine technology of Dongfeng Cummins is very mature, and the service life of remanufactured products can reach more than 70% of the new products, and the price of the engine after passing the “old change” is only About 50% of the original price of the engine is very cost-effective.

The remanufactured engine is certainly the main direction of future engine sales. At present, Dongfeng Cummins' remanufactured engine products already have mass production capacity. In terms of price, remanufactured products are more competitive; in terms of performance and quality, remanufactured products adopt the same standards as new products; enjoying the same warranty claim policy in terms of after-sales, maintenance and maintenance gives users more peace of mind.

Pneumatic Valve

Pneumatic ball valve is a ball valve equipped with a pneumatic actuator. The execution speed of the pneumatic actuator is relatively fast. The fastest switching speed is 0.05 seconds / time, so it is usually also called pneumatic quick cut-off ball valve. Pneumatic ball valve is usually equipped with various accessories, such as solenoid valve, air source treatment triplet, limit switch, positioner, control box, etc., to realize local control and remote centralized control. The valve can be controlled in the control room without running to the site or high altitude and dangerous areas for manual control, which saves human resources, time and safety to a great extent.

The pneumatic ball valve can be closed tightly only by using the pneumatic actuator to rotate 90 degrees with the air source and a small rotating torque. The completely equal inner cavity of the valve body provides a very small resistance and straight flow channel for the medium. It is generally considered that the ball valve is most suitable for direct opening and closing. The main feature of the ball valve is its compact structure and easy operation and maintenance. It is suitable for general working media such as water, solvent, acid and natural gas, as well as media with poor working conditions, such as oxygen, hydrogen peroxide, methane and ethylene. The ball valve body can be integral or combined.

Pneumatic butterfly valve is composed of pneumatic actuator and butterfly valve. Pneumatic butterfly valve is a pneumatic valve that uses the circular butterfly plate rotating with the valve stem as the opening and closing property to realize the opening and closing action. It is mainly used as a block valve. It can also be designed to have the function of regulation or section valve and regulation. Butterfly valve is more and more used in low-pressure large and medium-sized pipelines. Classification of pneumatic butterfly valve: stainless steel pneumatic butterfly valve, hard seal pneumatic butterfly valve, soft seal pneumatic butterfly valve and carbon steel pneumatic butterfly valve. The main advantages of pneumatic butterfly valve are simple structure, small volume, light weight and low cost. The characteristics of pneumatic butterfly valve are particularly remarkable. It is installed in a high-altitude concealed channel, controlled by two position five way solenoid valve, easy to operate and can also adjust the flow medium.
