The variable capacity pump makes the hydraulic output power always match with the system requirement. No extra-energy lost via the overflow valve. Comparing with traditional proportioning pump machines, energy saving efficiency is around 25%-50%, which reduces cost obviously.
Moreover, a larger flow rate pump can be used with the same output motor, which increases machine efficiency for about 30% in particular models. Not only the production cycle time is shorter, but also it can achieve the requirements of precise thin wall parts injection.
Additionally, the V-series machines produce less heat to the workshop and work in more stable hydraulic oil temperature. It means less than 70% cooling water is needed, and less air-conditioning expenses for the workshop also. And, O-ring & oil sealing are much more long lasting in lower working temperature. Consequently, the machines have less service problems and save expenses in maintenance.
V-series Energy-saving Star is equipped with high precision oil filtering device, the high quality imported parts. In normal operation, the pollution rate is as low as the NAS (National Aerospace Standard) level 8. V-series Energy-saving Star, it is the ideal machine for the modern workshop, environmental-friendly and cost-effective.
