Power saving devices

Power saving device market potential

      China's current total installed capacity of the motor accounted for more than 70% of the current total electricity consumption, of which nearly 70% of the motor drag the load is the fan, pumps, compressors, etc., of which nearly 70% of the motor for speed , That is about 200 million kilowatts of the motor in a state of wasteful operation. In contrast, China's GNP energy consumption is made
Up to 4-8 times the country, the energy utilization rate is less than 70% of the developed countries, and coal, oil and other primary energy and increasingly tense, energy issues have become China's largest strategic issues, both from the current business efficiency and future The energy of the links are very important.

     Our company combined with the current motor design margin is too large, the use of frequent changes in operating conditions, the use of frequency control, fixed frequency transfer, harmonic control, power factor improvement and soft start and other technical means to design a new generation of power saving device , Effectively improve the efficiency of the motor, save energy, reduce equipment maintenance costs.

Saving principle

     Power-saving device is designed for all types of motor-driven power-saving devices, the power-saving principle mainly: frequency control, fixed frequency power, harmonic processing, dual CPU operation, regulation, power improvement, automatic tracking.

Applications

     Mainly used for: injection molding machines, air compressors, fans, pumps, central air conditioning, escalators and other power consumption of large power equipment, energy-saving transformation.

Application of Power Saving Device for Injection Molding Machine

First, the injection molding machine power consumption analysis

    1, the hydraulic system of the pump power consumption;
    2, the power consumption of the heater;
    3, the circulating cooling water pump power consumption.

　　Which the hydraulic pump power consumption of the entire injection molding machine power consumption of more than 80%, so reduce its power consumption is the key to energy-saving injection molding machine. Injection molding machine in the mold, clamping, injection, cooling and other stages of the required pressure and flow
Are changing, when the injection molding machine oil demand changes, by the oil pump outlet in the relief valve to adjust the load pressure and flow, while the motor output power unchanged, resulting in energy waste.
At the same time, the motor in low load state work: motor efficiency and power factor is very low, reactive power consumption is great. Taken together, the traditional injection molding machine hydraulic system there is a serious waste of energy.
Injection molding machine dedicated energy-saving device can automatically according to the injection molding machine's own working pressure and flow signal, real-time analysis and calculation, synchronous control of the energy-saving device output frequency and voltage, so as to accurately adjust the pump
Speed, so that the actual pump fuel supply and injection molding machine working flow demand is consistent. In order to ensure the stability of the system under the premise of the work, the original injection molding machine to control the phenomenon of the minimum state, thus substantial savings
Can consume.
Example: The following figure is a comparison of the measured power consumption curve in the energy saving state and in the normal state when the power saving device is applied to a Yilida E160 machine (motor power 18.5KW).

Second, the characteristics of injection molding machine energy-saving devices

1, the general conditions of energy-saving rate of up to 30% -50%; under normal circumstances, 6-12 months to recover all the investment;    2, to reduce the use of injection molding machine pump, motor bearings, pump blades and other wear and tear to extend its service life, reduce replacement maintenance costs;    3, if the cost of saving maintenance included, then the recovery period can be shortened;    4, reduce the hydraulic oil temperature, reduce the amount of cooling water. With soft start characteristics, no large current shock when starting;    5, electricity / power switch. If the power-saving operation fails, can switch to the mains running, does not affect the production;    6, perfect operation instructions and fault query function. Keep the injection pump oil pump original Y / △ start running the same;    7, improve the power factor, reduce reactive power loss, reduce line loss, to prevent line aging;    8, the original injection molding machine hydraulic system and computer control system does not make changes;    9, the device is equipped with a special reactor to eliminate the equipment generated by the third harmonic, 5th harmonic, 7 harmonics, 13 harmonics and other high-order harmonics, but also to eliminate the surge, to avoid the grid voltage Fluctuations in the equipment caused by interference to ensure the quality of power supply;    10, high-quality movement, warranty for one year, the normal life of equipment for nearly a decade, reliable quality.
