The theme of this competition was “Chinese Machines Gathering the World†. Vice Governor of Zhejiang Province Sun Jingxi, Vice Governor of Henan Province Wang Tie, President of China Agricultural Mechanization Association Liu Xian, Chairman of China Agricultural Machinery Industry Association Chen Zhi, Chairman of China Agricultural Machinery Distribution Association Mao Hong, and Editor-in-Chief of Farmer Daily News Hu Leming Jiang Weidong, chairman of Shandong Wuzheng Group, jointly unveiled the 4th China Agricultural Robot Contest.
The 4th China Agricultural Robot Contest kicked off
The China Agricultural Machinery Contest has been successfully held for three times, and it is becoming more and more attractive to the national agricultural machine operators. It is understood that the content of this year's competition is very practical. The competition type is set up for men's and women's competitions, individual/team competitions, field competitions, regular seasons, invitational competitions, and combined with the timely characteristics of the agricultural conditions, to achieve the "land ratio" Wide appeal.

The designated model of this competition is Wuzhengshan Taishan 1404 tractor, corn harvester and so on.
Expansion Tank
Normally expansion tank is made by semi-transparent materials, such as plastic. The reason why use this kind material is that we can easily observed the liquid level directly through the box instead of opening the cap.
The operating principle of expansion tank is that, when people run cars, the temperature of the coolant circulating through the water jackets naturally increases which will increase pressure in the cooling system. When the pressure builds to a high enough point, the radiator cap allows that pressure to escape into the coolant reservoir through a small hose, called an overflow hose connected by the neck of the radiator to the expansion tank. Most of the coolant that is forced into the expansion tank returns to the radiator naturally after a few hours or when the engine is cold.
As engine coolant heats up, it expands. The coolant expansion tank provides additional storage for the expanding coolant and is commonly the location where coolant is added to the engine.
Without expansion tank, cooling systems would explode under pressure or the coolant would be forced from the overflow tube on the radiator and leak onto the road. It is advisable to check expansion tank regularly.
We can provide all kinds of expansion tank and brake fluid tanks with high quality and reasonable price. As we all know, expansion tank is a vital component in our car`s cooling system.
