Equipped with energy efficient servo motor Technology and robust gear pumps, the JU/j series machines are optimized for peak performance. Haitian’s patented servo motor technology system ensures superior performance compared to machines on the market today.
The motors are cooled by air or oil which provide Stable and lower operating noise compared to normal electric motors. The compact size of the servo system provides more space with ease of access compared to traditional systems. The hydraulic system is optimized for quick response and Energy efficiency. The clamping system utilizes servo control with pressure feedback for constant and effective control throughout the cycle. Major benefits can be observed during the hold pressure phase of the cycle. The motors only provide oil flow which is required for maintaining pressure stability, which greatly reduces energy consumption.
Another benefit of the JU/j series is the overall Operating noise levels. The machine is much quieter compared to traditional machines, providing for a better work environment. The overall service life is extended due to the lower oil movement through the hydraulic system. The cooling requirement for the System is 80% less than traditional systems, which is better for the environment and conserveswater consumption.
Overal l the JU/j series machines provides significant Customer advantage for large machine energy savings.
