In our operations in the process of injection molding machine, we will know how to how to transform the detailed parameters for injection molding machine more energy saving province electricity, then teach you how to set the parameters of injection molding machine by injection molding machine company. The advantage of injection molding machine and energy saving system, servo energy-saving system: the advantages of super energy-saving: compared to using quantitative pump hydraulic system, the energy saving effect of 40 and 80%. High stability: due to the pressure and flow closed loop system, obviously improve the system stability, under normal circumstances, the repeat precision products weight can be controlled at 0. 3%, after customers to use servo system, product qualified rate is high, the original per shift phenomenon without the need to adjust the machine parameters, technical personnel can make time for study more innovation, efficiency, etc. High precision: due to the moment of inertia of tiny servo motor, system response speed, up to 50 ms, to be precise adjustment of injection molding process is more easy to meet the requirements. Low noise: servo system relative quantitative pump system, noise is decreased obviously, change the working environment more environmentally friendly. Low oil temperature, due to the system itself fever decreased significantly, even without the need for cooling water, also can keep the oil temperature at lower temperature, significantly prolong the service life of hydraulic oil and hydraulic accessories. Low-input high returns: in general, investment in equipment in 6 - 12 months can take back ( According to the product process and regional electricity prices have certain differences) 。 Super energy-saving: compared with the traditional quantitative pump and variable pump system, servo oil pump control system is a combination of servo motor stepless speed regulation characteristic of rapid and independently regulate the hydraulic characteristics of hydraulic oil pump, a huge energy saving potential, compared the quantitative pump energy saving 40% 80% high stability: 1, the repeat precision, fast response speed, safeguard the open, clamping precision shoot glue end point position precision can reach 0. 1 mm: cooperate with precision mould, can achieve zero. 3% of the precision injection molding. 2, pressure control precision, high precision, high response of PID algorithm module is very stable, the system pressure pressure fluctuation below & plusmn; 0. 5 bar, compared with the traditional hydraulic press showed stronger stability of shoot rubber molding product percent of pass is greatly increased. High precision: due to the moment of inertia of tiny servo motor, system response speed, up to 50 ms, to be precise adjustment of injection molding process is more easy to meet the requirements. Low noise: equipped with low noise screw pump servo energy-saving injection molding machine, under the excellent PID control algorithm module, noise is much lower than normal injection molding machine, quiet operation, improve the working environment. Low oil temperature, due to the system itself fever decreased significantly, even without the need for cooling water, also can keep the oil temperature at lower temperature, significantly prolong the service life of hydraulic oil and hydraulic accessories. Low-input high returns: in general, investment in equipment in 6 - 12 months can take back ( According to the product process and regional electricity prices have certain differences) 。 Energy-saving reconstruct servo economizer injection molding machine, injection molding machine, injection molding machine frequency converter, servo variable frequency economizer: a, the shortcomings of high energy consumption of the traditional injection molding machine: most of the current quantitative pump injection molding machine for hydraulic system, the oil pump motor at a constant speed to provide a constant flow of redundant hydraulic oil backflow through the overflow valve, this process is called high pressure throttle. High-pressure throttle is commonly 40% ~ 65% efficiency, energy loss up to 45% ~ 75%. At the same time, due to the long-term circulating at full speed, hydraulic oil and hydraulic parts, mechanical parts of the violent friction, causing the oil temperature is too high, the noise is too large, the phenomenon such as mechanical life expectancy. Second, the injection molding machine special design principle of the ac servo system, is based on injection molding machine in the process of concrete operation needed to control the pressure and speed of the parameter to designer, after program optimization, with pressure rise faster, control precision, high repeat positioning accuracy. Compared with the traditional hydraulic control, energy saving, high efficiency, low rejection rate, power rating from 7. 5 kw to 55 kw optional. Can meet the 4000 tonnage injection molding machine, is unique among the counterparts. Of three, servo control system: servo system by the servo controller, servo motor, oil pump, encoder, pressure sensor, etc, four, transformation and working principle: the original injection molding machine in and out of the tubing to be removed, transfer to the servo control system of oil pump, can change the original motor on the power cord after series directly to the servo controller, at the same time take the injection molding machine's pressure, flow rate signal. Permanent magnet is used to produce magnetic field is also higher than the efficiency of the magnetic fields generated by electromagnetic or inductance, because to avoid the loss of the coil and the eddy current loss. Servo motor RPM speed from 0 to 2000 RPM, need only 0. 5 seconds. Therefore, using variable speed servo motor to drive oil pump, motor speed faster than normal. Servo motor in braking in the generator, drive braking resistor, the kinetic energy is on the brake resistance to heat, send out in the atmosphere. Some plastic injection factory in the whole machine adopts absorbs the kinetic energy of braking energy storage battery, and then release the drive motor. Finally, the injection molding machine factory has pointed out that this fully embodies the essence of energy saving: use additional equipment to save ( Here should be called recycled) Energy. Is popular said, under normal circumstances, servo motor under the same power consumption, can produce the equivalent of more than three times of general motor's power output, also is to use less than a third of the power can reach the same general motor power output.
