As global energy crises intensify, energy-saving technologies for hydraulic systems have become a key research focus. Chuangyuecheng's Enterprise Technology R&D Center has recently achieved a significant breakthrough in this field.
I. Research on Variable Pump Control Technology
Traditional hydraulic systems use a fixed-displacement pump with a relief valve for constant-pressure control, resulting in significant energy losses. Our R&D team developed an intelligent variable-pump control system that adjusts output flow and pressure in real time based on load requirements, achieving energy savings of 30%–50%.
II. Application of Energy Recovery Technology
In the lowering phase of construction machinery, gravitational potential energy can be converted into electrical energy by hydraulic motors. Our energy recovery system has been successfully deployed in a crane project for a major port group, achieving an overall energy savings rate of 25%.
3. Optimization of Intelligent Control Strategy
Using a fuzzy PID control algorithm, the system automatically optimizes control parameters based on operating conditions to reduce pressure fluctuations and energy loss. Test data show that system response speed increased by 20% and energy consumption decreased by 15%.
Chuangyuecheng Enterprise will continue to deepen research on hydraulic energy-saving technologies and promote green, sustainable development in the industry.
