1、 Energy consumption analysis of injection molding machine
2、 Advantages of LD servo system
1) At present, the vast majority of domestic injection molding machines are hydraulic drive injection molding machines with high energy consumption, which are well-known "electric tiger". In 2008, the total output of plastic products processed and exported by domestic demand (7.8 kg plastic products per capita) was 55.1 million tons, and the unit consumption of plastic products was 0.8 kW · H / kg. The power consumption of plastic injection molding products was quite amazing. The power system accounted for 70% of the power consumption of the plastic machine. If the whole system was replaced by Shengmai servo system, 60% of the energy could be saved, and 6.2 billion kwh of electricity could be saved in one year.
2) Water saving servo control energy saving precision injection machine can also save a lot of cooling water and power consumption of cooling water pump. If all of them are switched to Shengmai servo power system, 300 million cubic meters of water resources can be saved a year to ease the current water shortage.
3) Compared with the traditional hydraulic power system, the hydraulic oil consumption of the oil saving servo power system is reduced by 1 / 2-1 / 3, and the service life of the hydraulic oil is extended by 2-3 times compared with the traditional hydraulic power system, which greatly reduces the use cost and reduces the pollution emission.
