Sunward made a breakthrough in electro-hydraulic control of construction machinery

September 09, 2021

April 13, Hunan Machinery Industry Association held in Changsha organized by the Sunward Intelligent Equipment Co., Ltd. developed "engineering machinery electro-hydraulic transmission and control system key technologies" project scientific and technological achievements appraisal. Appraisal Committee by the National Defense Science and Technology University, Central South University, Hunan University, the National Building Urban Construction Machinery Quality Supervision and Inspection Center and other seven universities and third-party testing agencies professors and experts. The committee listened to the project team's work report and technical research report, scrutinized the appraisal materials and observed the demo of the result prototype on the spot. Experts at the meeting agreed that the project achievements of "key technologies of electro-hydraulic transmission and control system for construction machinery" have made a contribution to breaking through the bottleneck of China's construction machinery industry that has long been subject to restraint of core technologies and development of the industry but not strong. The project achievements are advanced Highly appraised by nature, innovation and market application prospect.
Appraisal experts pointed out: The project abandoned the long-term domestic mapping imitation model in the development of electro-hydraulic control system of construction machinery and proposed a brand-new development method to form a key core component development flow. Through the research of system integration and control technology, the energy utilization rate and dynamic performance of construction machinery are effectively improved. The highly efficient and energy-saving electro-hydraulic control multi-way valve set developed has complete independent intellectual property rights, good product versatility, low pressure loss, Good, can be achieved full arm and boom control; developed construction machinery controller computing ability, the underlying procedures open, rich library functions. The project passed the test of the third-party authority and obtained end-user approval, which has great market potential.
