Generally, the normal type supercharged diesel engine can be normally used in the plateau area at an altitude of 25003500m or less. However, since the original supercharger is not specially designed and matched for special working conditions in ultra-high altitude areas, its power and economy are used in areas above 3500m. The indicator will drop and cause problems such as a sharp rise in the supercharger speed, a right shift in the matching surge line, a left shift in the blocked zone, a narrower flow range, and a reduced working range of the compressor.
The machine is re-matched, and the amount of change is increased to increase the cost, but it is greatly beneficial to the reliability and service life of the whole machine. For example, the Komatsu D65 matched S6D125 has a displacement of 11L turbocharged diesel engine, and the Carter D6 bulldozer matches the engine to 1015L. Therefore, it is better to use a large displacement engine with a large power reserve on the bulldozer product. Method.
For wheeled construction machinery products adapted to the plateau environment, the engine should be re-matched first, considering the adaptability to the altitude of 20003000m, and sufficient space for the high altitude environment of 4500m. Due to the low price of wheeled products, domestic products have been in the low-end low-price stage in engine matching.
The harsh working conditions of the plateau environment put forward high requirements for all aspects of engine performance. It is necessary to ensure product reliability. In terms of engine matching, it is necessary to consider both power and torque reserves, and to select advanced technical performance indicators and reliable quality. Brand-name products, the introduction of technology as the first choice, but also leave sufficient room for power reserves. The matching of the 6CT813) 215 diesel engine produced by Dongfeng Cummins on the ZL50 wheel loader is a better choice.
This inflatable river tubes is more secure than the ordinary swimming pool circle. If it is a natural river, it is easy to have sharp edges such as stone and other sharp margins to cut the swimming ring. Generally, wearing bubble life jackets. Air chamber.
The Pool Floats can customize the color and pattern, or the inflatable river tubes used by multiple or single people. The materials used are also more wear-resistant, not easy to damage and leak, and can be more pleasant to play in the river.
