Product Description

     VY−JY Servo Feature Energy Saving Cabinet Inverter is a high-performance vector control Servo Feature Energy Saving Cabinet Inverter released by Shenzhen V&T Technologies Co., Ltd. for the Injection molding machine industry.
        The driver adopts speed sensorless vector control technology technology,  the world-leading technology, to offer excellent control performance and combine the application characteristics in China market to further enhance the driver reliability, environment adaptability and customized and industrialized design. It can better meet the demands of the various drive applications.
       Using vane pump or gear pump, hydraulic oil pump for injection molding machine is generally typical positive displacement pump, whose oil supply is proportional to the pump's rotating speed. The oil supply of the pump is constant when the pump is under mains supply 50Hz basically constant speed rotation, while the actual operating pressure and flow of the injection molding machine vary all the time, sometimes big, sometimes small, and sometimes even zero. When the actual flow is low, the oil supply of the pump is far greaterthan the load's actual consumption, and all superfluous hydraulic oil under high pressure overflows through an overflow valve, and gives forth a lot of thermal energy, which is actually a portion of electric energy absorbed by the oil pump motor from the power grid. Since low flow lasts long, the electric energy wasted is big. Therefore, the hydraulic system of injection molding machine has serious energy waste problem.
