Servo energy saving injection moulding machine systems, energy-saving 50%~80%:
Servo energy saving injection moulding machine, plastic injection molding machine energy-saving reconstruction, plastic injection molding machine frequency converters, servo frequency conversion energy saving:
A disadvantage of high energy consumption, traditional injection molding machine: currently most of the plastic injection molding machine for quantitative pump hydraulic system, provide a constant flow of pump motor at a constant speed, excess hydraulic fluid through the relief valve backflow, this process known as high voltage throttling. efficiency is generally 40%~65% a stream of high pressure, energy loss by up to 45%~75%.
At the same time, long-term hydraulic oil circulating flow at full speed, and hydraulic parts, intense friction of mechanical parts, causing excessive oil temperature, excessive noise, mechanical life shortening and so on.
Second, special AC servo system of injection molding machine design principle: is based on the process of injection molding machine in the specific operation you want in the control of pressure and speed parameters specially designed, after program optimization, with pressure rises quickly, precision control, high repeat positioning accuracy. Compared with conventional hydraulic control, with energy-saving, high efficiency, low waste rates, power levels between 7.5KW is optional. To meet maximum 4,000 tons of plastic injection molding machine, in the peer is unique.
Third, servo control system of composition: servo systems by servo controllers, servo motor, pump, encoder, pressure sensors, and other components,
Four, transformation and how it works: the original inlet and outlet tubing on the injection molding machine removed, on the transfer to the servo control system on pump, can change the power lines on the original motor directly after in-line to the servo controller, at the same time taking the injection machine, pressure and flow of signals.
Used to generate magnetic fields which use electromagnetic or permanent magnet inductor produces a magnetic field is more efficient because avoiding a coil losses and Eddy current losses. Servo motor from 0rpm to 2000rpm, only 0.05 seconds. Therefore, with variable speed servo motor to drive the oil pump, motor speed more quickly than normal.
