| Advantages of energy-saving system for injection molding machine, servo energy saving system:
Ultra energy saving: compared with the use of a quantitative pump hydraulic system, energy saving effect in 40-80%.
High stability: due to the use of pressure and flow closed-loop system, the system stability is significantly improved, the general situation, the weight of the product can be controlled in 0.3%, after the customer use servo system, the product qualified rate is high, the original need to adjust the machine parameters of the phenomenon did not have, the technical staff can spare time to study some of the innovation, efficiency and other aspects of things.
High precision density: because the servo motor of the moment of inertia is very small, the system response speed is fast, the highest reached 50ms, the need for precision adjustment of injection molding process is more easy to meet the requirements. Low noise: servo system relative to the quantitative pump system, noise significantly lower, change the working environment more environmentally friendly.
Low temperature: due to the significant decrease in the self heating of the system, even without requiring the use of cooling water, also can keep the temperature in the low temperature, prolong the hydraulic oil and hydraulic parts service life.
Low investment and high returns: in general, the equipment investment in 6-12 months can be recovered (according to the product process and regional electricity price has a certain difference).
Super energy saving: compared with the traditional variable pump system, the servo pump control system combines the servo motor with the speed stepless speed regulation characteristic and the hydraulic oil pump's independent adjustment of oil pressure. It brings huge energy saving potential, compared with the quantitative pump energy saving 40%-80%
High stability:
1, position accuracy: fast response speed to guarantee the opening and closing precision, the accuracy of the shot end position can be reached 0.1mm: with the precision mold, can achieve 0.3% of injection precision.
2, the pressure control precision: high precision, high response PID algorithm module to make the system pressure is very stable, the pressure fluctuation is less than + 0.5bar, compared with the traditional hydraulic pressure machine performance is stronger than the injection molding product quality improvement. High precision density: because the servo motor of the moment of inertia is very small, the system response speed is fast, the highest reached 50ms, the need for precision adjustment of injection molding process is more easy to meet the requirements. Low noise: the configuration of the servo energy-saving injection molding machine with low noise, the excellent PID algorithm module control, noise is significantly lower than the ordinary injection molding machine, realize the quiet operation, improve the working environment. Low temperature: due to the significant decrease in the self heating of the system, even without requiring the use of cooling water, also can keep the temperature in the low temperature, prolong the hydraulic oil and hydraulic parts service life. Low investment and high returns: in general, the equipment investment in 6-12 months can be recovered (according to the product process and regional electricity price has a certain difference).
Injection molding machine servo energy saving device, injection molding machine energy saving, injection molding machine, servo frequency converter:
One, the traditional injection molding machine energy consumption is high, the current majority of injection molding machine for the quantitative pump hydraulic system, the oil pump motor with constant speed to provide a constant flow, excess hydraulic oil through the overflow valve, this process is called high pressure. The high efficiency of the high efficiency of the 40%~65%, the energy loss of as much as 45%~75%. At the same time, due to the hydraulic oil for a long time of full circulation, and hydraulic parts, mechanical parts of intense friction, resulting in high temperature, noise, mechanical life shortening phenomenon.
Two. The design principle of the special type AC servo system of the injection molding machine is designed according to the pressure and speed parameters of the injection molding machine in the specific operation process. Compared with the traditional hydraulic control, with energy saving, high efficiency, low rejection rate, power levels from 7.5KW to 55KW optional. Can meet the maximum 4000 tons of plastic injection molding machine, in the peer is unique.
Three, servo control system: servo system by the servo controller, servo motor, oil pump, encoder, pressure sensor, etc.,
Four, transformation and work principle: the original injection molding machine into the pipe, the pipe down, to the servo control system on the oil pump, the power on the original motor on the series to the servo controller, while taking the injection molding machine pressure, flow signal.
The use of permanent magnet to produce a magnetic field is also higher than the efficiency of the magnetic field generated by the magnetic field, because of the loss of the coil and the loss of the eddy current. Servo motor from 0RPM to 2000rpm, only 0.05 seconds. Therefore, the variable speed servo motor to drive the oil pump, the motor speed is faster than the normal use. The servo motor is changed into a generator in the braking, the brake resistance, and the kinetic energy is changed into heat energy in the brake resistance, and the energy is distributed in the atmosphere. Some injection molding machine factory in the whole motor uses the energy storage battery to absorb the kinetic energy, and then release the drive motor.
This fully reflects the nature of energy conservation: the use of additional equipment to save (in here should be called recycling) energy. It is popular to say: under normal circumstances, the servo motor in the same power consumption, can produce equivalent to three times the power output of general motors, that is, with less than 1/3 of the power can reach the same power output.
