Agricultural machinery has various shapes, complicated structure and extreme standards in work. Agricultural machinery has many special requirements for hydraulic components, such as high price and stability. The key requirements of agricultural machinery for hydraulic technology include:
1. Environmental protection and energy saving technology. The driving force of agricultural machinery in China has reached 450 million KW. The application of environmental protection and energy saving technology can not only Rail car cycloid motor The server features have been improved, reducing environmental pollution to the natural environment, and every point of energy consumption reduction represents the driving force of saving 45 billion kilowatts. Its great social development and economic benefits have attracted many researchers to invest great energy and intelligence in this fund, and have achieved many results and progress.
2、 Cabin opener hydraulic motor Requirements for hydrostatic drive technology. Hydrostatic driver equipment can change speed steplessly, which is convenient for reasonable layout, with large specific power, wide range of speed changes, and good reliability of low gear. It is especially suitable for agricultural machinery and road building machinery with diversified structure and shape and low driving speed. The combined harvester with hydrostatic drive has higher working efficiency and less auxiliary working time than that with mechanical drive. The working efficiency is increased by 10~30%, and the net yield is 1~2% higher than that of mechanical drive. The actual operation is convenient, comfortable, reduces labor efficiency, facilitates maintenance, and has low equipment failure rate, At present, 30% of the common failures of domestic mechanical transmission combine harvesters are caused by the transmission, which vibrates greatly and endangers the service life of other working components. The combine harvester with hydrostatic drive can make the automobile engine work under the objective and fixed working conditions, ensure the constant frequency work of other components, and have a good low and stable driving speed, which is suitable for obtaining increased crops and fallen crops. However, the mechanical transmission combine harvester is more likely to be blocked when it has a bumper harvest. What it brings to farmers is not the joy of a bumper harvest, but the damage of redundant energy.
3. No leakage technology. Leakage and noise, which are common faults in the early stage, are persistent diseases in the hydraulic field, and are also key factors limiting the application of hydraulic technology. At present, the non leakage technology in hydraulic technology will be widely used, including the development and design of new three-way joint components and external thread cartridge valve. The slow marketing and promotion of the related technologies, such as the sealing property of components and the environmental pollution control technology of hydraulic system software, play a key role in improving the physical performance of agriculture and animal husbandry in China.
Hydraulic technology has great potential in the application of agricultural machinery. The application prospect of hydraulic technology in agricultural machinery is very broad, and the application of hydraulic parts of agricultural machinery in China should be said to be the general trend. With the increase of farmers' consumption power in China, farmers are moving from the pursuit of perfect low price to the pursuit of perfect good characteristics and comfortable practical operation, which has created resource advantages for agricultural machinery using hydraulic technology. Due to the application of hydraulic technology, the quality and technical composition of agricultural machinery in China will be significantly improved. It plays an overall role in reducing and improving the technical differences in China, promoting the capture of China's sales market, and has obvious harm to farmers in alleviating labor efficiency, improving the quality of life, and improving the return on project investment.
