3. The top of the diesel Engine Piston often has a variety of pits, and its specific shape, position and size must be adapted to the formation and combustion requirements of the diesel engine mixture.
The production process of a piston usually involves several steps, including casting, machining, heat treatment, surface treatment and assembly. MITSUBISHI Piston set,Engine piston set for MITSUBISHI,Original piston Set,Original MITSUBISHI Engine piston 1D auto parts , https://www.1dauto.com
The increase in demand, intensified development competition in the industry, indirectly brought about upgrading of the drying equipment industry, and has shown several major development trends in recent years.
First, the products tend to be high-grade. The technical level of drying equipment has been further improved. The development of environment-friendly drying equipment products has become an important task for the company. The industry began to aim at ergonomic design, improve the operation of intelligence, reduce noise and vibration, pay attention to the appearance of modeling The design requirements are even higher. Second, the market moved westward. With the further improvement of China's transportation facilities and the rising demand for western industrial development, the central and western regions have become new investment hotspots and have great potential for exploitation. Thirdly, many well-known foreign companies have increased their investment in the Chinese market, the internal development pressure has increased, competition has intensified, and technology upgrading has become impatient.
Analysts of the industry analyzed that in the type of drying equipment, atmospheric pressure drying equipment and vacuum drying equipment will be mainly used for hot air heating, and users in other special fields such as far-infrared drying equipment and microwave drying equipment will gradually expand the number of applications; For drug drying, the demand for larger-scale equipment in vacuum freeze-drying equipment will increase; the demand for equipment with a combination of functions (eg, granulation drying, dry filtration) will also increase; high-automated drying equipment will be used in some applications. popular. In addition, the appearance quality of drying equipment will be more and more emphasized. The corrosion resistance and reliable service life of corrosive material drying equipment will be of particular concern to users.
In fact, China's drying equipment industry has entered the stage of rapid development along with the adjustment of the green development direction of the “Twelfth Five-Year Planâ€. It has already ended the problem of importing a large number of high-end core technologies, indicating that China’s technological level and energy-saving awareness are both high. has seen an increase. However, compared with foreign companies, the scale of development is still relatively small. Moreover, the technology reserves are insufficient and the means of processing equipment are somewhat primitive. At the same time, many dry companies are ignoring the quality of their products in order to pursue profits, and products will show deviations during use.
In the new period of development, some new requirements are also prompting the industry to break from the inside out. At present, the hottest issue is environmental protection and energy conservation. Saving energy and reducing consumption is a global development issue. In the manufacturing process of drying equipment, it is also necessary to point out that although the current development from the traditional coal-type drying equipment to the power drying machine has been achieved, many innovations are still needed in the subsequent development. . For example, various joint heating methods, transplantation of heat pump and heat pipe technology, development of solar dryers, etc., as well as the development of automatic control technology for dryers to ensure the realization of optimal operating conditions, in addition to improving the environmental protection measures of dryers Reducing the leakage of dust and exhaust gas, etc., will also be a need for further research.
As the process of economic globalization accelerates, more multinational companies will shift their targets to the Chinese market, and domestic drying equipment manufacturers are facing tremendous pressure. The increasingly fierce competition requires that our enterprises must improve their product quality through technological advancement, the absorption of advanced foreign technology, and independent innovation. The idea of ​​product development should focus on the large-scale equipment, the degree of automation of control, the surface treatment quality of equipment, and the selection of corrosion-resistant materials, and develop multi-functional combined machines to promote the continuous extension of the product life cycle. Industry associations should organize more enterprises to participate in international technical exchanges, absorb the latest technological achievements, and accelerate the improvement of the industry-wide technology level.
1. Casting: The first step in the piston production process is casting. This involves pouring molten metal, such as aluminum alloy or cast iron, into a mold to form the desired piston shape.
2. Machining: Once the piston is cast, it is machined to perfect its shape and size. This involves using cutting tools, such as lathes and milling machines, to remove excess material and create the final shape of the piston.
3. Heat treatment: After processing, the piston is usually heat treated to improve its mechanical properties. This involves subjecting the piston to high temperatures and then cooling it slowly to achieve the desired level of hardness and strength.
4. Surface treatment: The piston is then subjected to surface treatment, such as anodizing or coating, to prevent wear and corrosion. Anodizing involves forming a protective oxide layer on the surface of the piston, while coating involves coating a material, such as ceramic or polymer, on the surface of the piston.
5. Assembly: Finally, the piston is assembled into a complete engine assembly with other components, such as piston rings and connecting rods.
The installation process must properly assemble the piston and other components together to ensure the normal operation and performance of the engine.
At present, the conventional drying equipment needed in the domestic market, as well as the main drying equipment needed in the international market, can basically be manufactured in China. This shows that the history of importing drying equipment in China has ended.

Piston is a reciprocating movement in the cylinder body of an automobile engine.
1. The basic structure of the piston can be divided into top, head and skirt. The top of the piston is the main part of the combustion chamber, and its shape is related to the selected combustion chamber form.
2. Gasoline engines mostly use flat-top pistons, which have the advantage of small heat absorption area.
