In January 2015, Dongfeng Cummins' product and application engineer teamed up with the deputy chief engineer of Dongfeng Heavy Industry to come to a white and green mountain range about 20 kilometers southwest of Mozhugongka County in Lhasa City, Tibet to understand the operating environment of the mining area and discuss the complete vehicle and engine pairing of the mining area. Adaptability requirements for working conditions. This belt, with an average elevation of 5,400 meters above sea level, has a bad climate, is deserted but has huge wealth, and is China's largest copper mining area. The mining area is the largest single industrial project in the Tibet Autonomous Region. The mining area is currently undergoing preparations such as road construction and infrastructure. A large-scale blasting operation is about to commence afterwards. The mining period will last for 50 to 70 years, and the mountains here will be leveled out and even become deep pits. The Dongfeng Heavy Industry Mining Dump Truck with Dongfeng Cummins QSZ13 engine will be transported here as a protagonist of “Yugong Yishanâ€. After investigation, engineers concluded that the most common problem of the engine in the mining area is that the fuel filter is easy to be clogged, leading to difficulty in starting. This type of problem is mainly caused by the poor quality of the oil in the mining area. In response to this type of problem, Dongfeng Cummins's electronically controlled engines have all installed “oil-water-bao†devices. At the same time, the entire vehicle will also be installed with high-accuracy filtering, high-capacity ash, or even secondary vehicle coarse filtering to maximize the Remove impurities from the fuel and reduce engine failures that may result. In addition, maintenance on time according to the maintenance cycle of the Dongfeng Cummins engine is also a preventive measure to reduce breakdowns. We believe that after careful and detailed customer research and analysis, we will take appropriate measures and make full preparations. In the future, Dongfeng Heavy Industry Mine Dump Trucks equipped with “Consumers†will soon emit more light and heat on the roof of the world to bring more benefits to customers. Multi-value returns.
