The air compressor is a mechanical device that compresses the volume of the gas and increases the pressure of the gas and delivers the gas. It can reduce the volume of the gas, increase the pressure, and have a certain kinetic energy, which can be used as mechanical power or other purposes.
Since the compressed high-temperature gas and high-temperature oil play the role of transmission power and power source in the air compressor, for the safe and benign operation of the air compressor, high-efficiency heat dissipation of the high-temperature gas and oil is required plate-fin heat exchange. It is widely used in air compressors with the advantages of high pressure resistance and large heat dissipation power per unit volume. We offer standard coolers or special custom cooler solutions for current different cubic air compressors, ensuring that the air compressors work long hours.
In summary, the industries used for compressed air include machinery, automotive, electronics, electric power, metallurgy, mining, construction, building materials, petroleum, chemical, petrochemical, textile, environmental protection, military and other industrial and civil production and life. each field.

[China Agricultural Machinery Industry News] In 2015, China's corn planting area was 572 million mu, with a total output of 223 million tons, accounting for 35.91% of China's total grain output of 621 million tons. It is a large food crop in China. In the same year, the total number of corn combine harvesters in China reached 420,000 units, an increase of 63,000 units, an increase of 17.8%. The national corn machine harvesting area reached 360 million mu, and the corn machine harvest level reached 63%, an increase of more than 6 percentage points over the previous year.
A total of more than 99,000 corn harvesters in the main corn producing areas participated in cross-regional machine harvesting operations, completing nearly 70 million mu of trans-regional operations, accounting for 19.6% of the total area. The inter-regional corn harvesting machine and operating area are obviously low, which is another “Nugget Land†to be developed in the field of agricultural machinery in China.
Maize cross-regional machine harvesting conditions mature balance corn machine supply and demand relationship
The conditions for carrying out corn inter-regional harvesting have matured. Taking Hanzhong City of Shaanxi Province as an example, the city's corn planting area is nearly 2 million mu, of which the suitable machine area is 1.5 million mu. However, China's agriculture faces many problems. First, the rural labor force has entered the urban secondary and tertiary industries in a large amount, and has absorbed about 280 million rural laborers, accounting for more than 65% of the rural labor force. Due to this factor, it is possible to make mechanical substitution of manpower in the field of agricultural production. Second, the continuous development and improvement of the socialist market economic system. With the rapid development of urbanization and the national economy, agricultural production is no longer the only means for farmers to make a living, but has become a commodity economic behavior of farmers. As a business behavior, we must pay attention to economic benefits and attach importance to input and output. The third is the commercialization of agricultural labor services. The daily value of labor has increased by more than 10 times compared with 15 years ago. If large-scale operation is realized, the planting area of ​​the household is 100 mu, and only one employee will be harvested. It takes 5 working days/mu and the cost is 300 yuan/mu (harvest, transportation, straw treatment, threshing, etc.). The machine is harvested, the ear picking type is 80 yuan/mu, and the harvesting grain type is 95 yuan/mu. The silage function is completed once and the grain harvesting and straw chopping silage operation is 125 yuan/mu, and the time is only artificial 1 /40-1/60, the cost of reducing the cost of 175-220 yuan. Therefore, the realization of corn harvest has become a necessary way to achieve large-scale agriculture.
How to make a dream come true
As can be seen from the above analysis, the potential market for corn harvesting is huge. Coupled with the successful practice of harvesting wheat and rice across the country in these years, and the demonstration and application of corn harvesting, the conditions for promoting corn harvesting across regions have been fully mature. If the local time requirements are met, the time for the good time is 6 days. With a working area of ​​250 mu/set, the city needs to achieve corn harvesting, and the number of corn combiners required is 6,000. According to the current corn market price of 8-12 thousand yuan / Taiwan, a special investment of 4.8-720 million yuan is required. Among them, agricultural producers are required to invest 3.36 to 504 million yuan, and the state machine to make up 1.44 to 216 million yuan.
From the perspective of corn production in China, China currently has coastal provinces in the east, Tibet and Xinjiang in the west, Hainan Province in the south, and Heihe River in Heilongjiang Province in the north. It is the only town in the world that is the “four seasons of corn†in spring, summer, autumn and winter. From the production time point of view, the time difference from east to west is 80-90 days, and the time difference from the south to the north is as high as 100 days. From a geographical perspective, this time difference is also more obvious. For example, Shaanxi Province, divided into southern Shaanxi, Guanzhong, and northern Shaanxi, is obviously three different time-spaces. Take the corn machine to collect, Shaanxi spring corn began to harvest in early July; autumn corn began harvesting in mid-September in southern Shaanxi, Guanzhong in mid-October, and northern Shaanxi in early November. The time difference is about 80 days. If properly organized, three operating areas can be realized in the province. The Taiwanese realized an area of ​​900-1300 mu, and the annual gross income can reach 9000-140,000 yuan. Based on net income, the investment payback period is less than 2.5 years. Such expected benefits, as long as the organization is right, cross-regional corn machine harvest will achieve extraordinary leaps and bounds.
Suggestions and countermeasures
Vigorously organize corn cross-regional collection and socialization services. In accordance with the idea of ​​“clear work area, moderate service radius, firm service target and stable operation incomeâ€, we will guide the new agricultural machinery service organizations such as large agricultural machinery, agricultural machinery cooperatives and agricultural machinery associations to start orders by implementing cross-regional operation services in specific areas. Work, farming, and one-stop work in the region, improve the professionalization, organization, and scale of the corn machine social service. Strengthen the maintenance and repair capacity of machinery and tools, grasp the safe production of corn machines, establish and improve the information dispatching service platform, further develop and develop the corn machinery harvesting operation market, improve the economic benefits of operators, and enhance the development potential of corn harvesting mechanization promotion and application. .
From the perspective of agricultural machinery cross-regional operations, macro-control of agricultural machinery increments is required. This is worth thinking about:
To maintain this rate of agricultural machinery development, we must let uneven development exist. From a nationwide perspective, it is necessary to maintain the balance of the total amount of machinery that can meet the demand through inter-regional operations, instead of pursuing an increase in quantity.
Second, to meet the development requirements of higher quality, we must give strength to the replacement. Retire and update the “double subsidy†for its scrap updates.
Third, to promote the development of cross-regional operations in depth and breadth, we must deal with the relationship between macro-control and micro-development.
Fourth, we must do something to make up for the opportunity, do something wrong, advance and retreat, adjust in time, and play the guiding and guiding role of machine compensation to ensure the quality and efficiency of development.
Plan ahead to prevent excessive development risks and improve the quality and efficiency of development. At present, the corn harvest has undergone polarization. The corn harvest in the fast-growing regions has reached more than 90%, while the slow-growing areas are still less than 20%. In some places, corn harvesting has not yet been initiated. We must treat this differently and adjust the policy as soon as possible so as to avoid the waste of social resources caused by excessive development. From the national level, we should grasp the balance between the total demand and total supply of corn machines in China under the conditions of inter-regional operations. In areas with high level of machine collection, the subsidy policy for agricultural machinery purchase should be changed from supplementary increment to supplemental replacement; in areas where the level of machine collection is relatively low and the supply is seriously insufficient, corn harvesting machinery should be listed as a purchase of governments at all levels. The scope of subsidies is tilted. Central government subsidy funds should gradually expand the scope of implementation of corn harvest machinery subsidies, increase subsidies, establish a diversified investment mechanism, create favorable conditions for the development of corn harvest mechanization, and accelerate its development.
