Under the guidance of the "dual carbon" goals, industrial energy-saving upgrades are expanding from large-scale equipment to core components. Shandong Yueheng Precision Bearing Manufacturing has seized this opportunity to enhance its core team's R&D and innovation, achieving phased results.
For example, the pump and fan, which occupy the largest part of the factory electricity, have been upgraded from ordinary bearings to low friction and high efficiency bearings, which has become a shortcut of energy saving with low investment and quick effect.
Friction is the 'invisible killer' of energy efficiency. A major water utility group upgraded its water supply pumping stations by replacing conventional bearings with high-efficiency bearings featuring optimized raceway design and sealing structures. Field tests revealed that each pump's operating current decreased by over 10%, resulting in an annual electricity savings of 45,000 kWh. With 20 such units in operation, this upgrade alone saves over 500,000 yuan in annual electricity costs.
Similar cases are common in cement plant fans and central air conditioning cooling water pumps. High-efficiency bearings employ ultra-precision machining to reduce friction torque and utilize low-resistance grease, enabling the equipment to operate more efficiently at the same output while significantly lowering energy consumption. Typically, the retrofit investment can be fully recovered within 1-2 years through electricity cost savings, with continued economic benefits thereafter.
