Detailed Description

ENERGY SAVER FOR INJECTION MOULDING MACHINE Principle It is investigated that the power consumption of hydraulic oil pump occupies over %80 of the total power consumption in injection moulding machine. The direct cause is that the running speed of oil pump motor is constant, that is to say, oil pump motor always rotates with topmost rated speed while hydraulic system of injection moulding machine is a load that has big heavy pressure and fluctuation of flow;in the process of clamping, mold-closing, injection, holding, cooling, knocking out, mold-opening, clearing material, the needed pressure and flow vary regularly. Consequently constant speed of rotation makes flow uncoordinated between oil pump and load, and waste power seriously. In view of this situation, our company has developed the energy saver for injection moulding machine, which adopts advanced computer control technology to control oil pump motor according to required technology of injection moulding machine.Constant pump has been developed to match energy saving variable pump and minimize the quantity of reflux of overflowing valve, it does not only greatly improve running effect but also saves the power and reduces noise. A. Features a) Energy saving ratio is up to %20 ~ %55. b) It can improve running effect of device, reduce the wear of device and lower maintenance cost. c) Free double circuit switch reverses between energy saving power and normal power to prevent power failure from normal production. d) Smooth startup and power-off eliminate hydraulic shock. and avoid strong electric current. e) The operation is simple and it is running synchronously. with injection moulding machine without any regulation. B.Applicable devices It is used in those places where they produce plastic, toys and mould with injection moulding machine.
