The engine is mainly composed of cylinder block, crankcase, cylinder head and cylinder head gasket. The crankcase, the part of the lower part of the cylinder block used to mount the crankshaft is called the crankcase, and the crankcase is divided into the crankcase and the lower crankcase. The upper crankcase is integrally formed with the cylinder block, and the lower crankcase is used for storing lubricating oil and closing the upper crankcase, so it is also called an oil sump, and the oil sump is rarely stressed, and is generally formed by stamping a thin steel plate. The shape depends on the overall arrangement of the engine and the capacity of the oil. The oil pan is equipped with a stabilizing oil baffle to prevent the oil surface from fluctuating excessively when the car is turned. The bottom of the oil pan is also equipped with an oil drain screw. Usually, the oil plug is equipped with a permanent magnet to absorb the metal chips in the lubricating oil and reduce the wear of the engine. A gasket is placed between the upper and lower crankcase joint surfaces to prevent oil leakage.

Promoting green development, building a resource-conserving, environment-friendly society, and significantly reducing the intensity of energy resource consumption and the emission intensity of pollutants have become China's binding indicators, and have become the focus of the development of various industries in China. Developing energy-saving and environmental protection industries and accelerating the transformation of development methods will also be the only way to promote social and economic development.
With the rapid advancement of comprehensive utilization technology of mineral resources and related industries, the total ore mining volume in China exceeded 5 billion tons in 2013. Crusher equipment has been widely used in resource extraction and mine construction. Therefore, upgrading the technological content, optimizing product quality, and accelerating the pace of energy conservation and emission reduction are the main tasks of the crusher industry.
At present, China's crushing machinery industry will usher in great opportunities for development, mainly reflected in three aspects:
First, the fiery development of the construction industry and building materials industry has also led to the development of the sand aggregate industry, which has also promoted the development of the crusher industry. High-quality crusher products can provide high-quality raw materials for construction materials such as concrete and dry mortar, so as to ensure the quality and efficiency of the building.
Second, infrastructure construction has become one of the most important tasks at present, and a large amount of construction waste will be generated during the construction of infrastructure. At present, China's construction waste has accounted for 35% of the total municipal waste. By 2020, China will have a new construction area of ​​approximately 30 billion square meters. Crusher machinery will play a major role in the recycling of construction waste.
Third, the use of crusher manufacturers pay attention to efficiency, but also pay attention to the environmental protection in the production process, such as the dust removal equipment on the production line, the equipment at the entrance and exit of the spray equipment and equipment improvements are to reduce the dust and noise during production The effective measures that these also require crusher manufacturers continue to innovate and improve products. To meet market demand, we can have a foothold and a development path for the company.
To this end, we will take advantage of the opportunity to adapt to the needs of the development of the situation, improve product quality and high-end brand building, while actively innovating and developing new products, vigorously promote the development of cleaner production and recycling economy, lead the development of the mining machinery industry, and seek growth for the green economy. The new way.
The crusher industry responds positively to the green call
With the development of social economy and culture and the increasingly serious environmental pollution, people’s awareness of environmental protection is getting higher and higher. Various industries are embarking on the green development path of energy saving and environmental protection, and they are the main equipment in mining machinery – crushers. No exception.
