Recently, in the Aksu area of ​​Xinjiang, a tractor attracted everyone's attention. "This big guy is really strong, the land is frozen, the plowing is effortless, and the most important thing is to drive comfortably. We need such a tractor. With the sound of the rumbling of the tractors in the field, Master Li, the big planter, kept admiring, and the local farmers on the scene discussed the tractor together.

The "big guy" in Master Li's mouth is a high-powered high-end intelligent tractor newly developed by the Revo Apos Group. It is currently testing the performance and reliability of the tractor under low temperature conditions.

It is understood that the Revo Apos Group regularly organizes product development personnel to enter the market. Meet face-to-face with users, dealers, etc. to understand user and market needs. Based on the information collected, R&D personnel conduct statistical analysis and turn it into a new product. However, before the product goes on the market, it is actually tested, simulating all the situations that the user may encounter during use, and testing the various durability of the vehicle with an approximate limit state.

Benazzi, the chief designer of Apos Tractor, told the author, “Product research and development should be guided by customer needs, and must be approached by users and walked into the field to understand what operating conditions the product meets, in order to understand the user's expectations of the product. Field testing The conditions are very strict and our goal is to deliver a product that is satisfactory to the user."

Benasi said that the Apolco high-powered smart tractor being tested in Xinjiang is also customer-oriented. Under the conditions of low temperature and heavy load in Xinjiang, the tester verified the tractor by simulating the daily operation of the user. jobs. Through testing, we can accurately grasp its performance, reliability, safety, understand its problems and deficiencies, and then continuously improve and improve the process and technology.

According to the test engineer's side, the tractors that participated in the test adhered to the environmental protection concept of Apos Green, and the product research and development strictly followed the non-road national four emission regulations. The product comes standard with a 4-speed power shift transmission with up to 60 gear speeds to meet different job speed requirements and optimize work efficiency. Large-displacement load-sensitive closed-heart hydraulic system, up to 5-channel electronically controlled hydraulic output valve, which reduces system power loss and saves fuel consumption for users by meeting the matching requirements of large-scale machines. The body continues the novel shape of the Apos family, the four-column cab has a wide field of view, air suspension operation, and integrated control platform to create a safe and comfortable driving environment for users.

It is understood that this time in Xinjiang, the high-end intelligent tractors of Apos are mainly engaged in 15 major cold test tests, including hydraulic oil pump (high pressure filter, low pressure filter) under low temperature conditions; hydraulic oil pump at low temperature Whether the flow rate under the condition meets the design requirements; whether the oil pipe joint has oil leakage under low temperature conditions; whether the antifreeze pipe joint will leak due to different materials under low temperature conditions; the pressure of each gear shift in the low temperature condition The state performance test under the condition; the temperature rise time of the hydraulic oil under low temperature conditions and the data basis for the gearbox hot car.

In southern Xinjiang, the area is sparsely populated. The test site is in a remote town, about 70 kilometers away from the county seat, and it still needs to cross more than 30 kilometers of the Gobi Desert no man's land. Although the temperature is low and the conditions are tough, the test team members have developed a rigorous test plan and completed it in strict time to ensure that the experimental problems and data are timely feedback, providing a basis for product improvement.

At present, the test team has successively completed one test project. After feedback to the relevant departments, the problems are improved in time, and the product performance and reliability are continuously improved.

The new endless, in the future, Revo Apos Group will continue to intensify innovation, develop new products that are smarter, more efficient and greener, continue to provide intelligent overall solutions for modern agriculture, and make more contributions to China's agricultural modernization.
