Because the servo motor does not use permanent magnet structure, and because the torque and inertia closely cooperate, the servo motor drive system eliminates the pulsating torque under the low inertia rotor, and has a good dynamic response range in the speed. Because the torque is generated by the induced current and has a high flux density, it can maintain a very low torque ripple.
The principle of automatic hollow forming machine is that the high speed of hydraulic pump is 1800 r/min. Considering the high speed noise and service life of hydraulic pump, the working speed of hydraulic pump is less than 1800 r/min, and the driving system of large displacement hydraulic pump and servo motor can not give full play to the excellent characteristics of AC servo motor for high speed operation. Improve the cost driven system. Plasticization capacity is greatly improved by the use of water-cooled closed groove feeding device, the use of advanced energy-saving speed control system, improve energy efficiency. In the past, most of the DC high-speed energy consumption or electromagnetic speed control technology, in recent years began to use AC frequency conversion energy-saving control technology, speed range, dynamic response, intelligent control efficiency factor and power.
A frequency converter motor energy in 20% ~ 30%, an energy-saving motor sliding more than 50% of plastic products, reducing electricity. Whether from the downstream market of food and medicine or plastic bottle manufacturers, China is still a small and medium-sized enterprise. In particular, the manufacture of some plastic bottles is still a family workshop for RS. For these groups, they must consider their cost when buying hollow molding. Automatic Dalian hollow molding price is high, will naturally make the manufacturer Else to consider purchasing semi-automatic handmade simple Dalian hollow molding. Therefore, the future is unlikely to achieve 100% of the market from Dalian hollow molding. Dalian hollow molding manufacturer Dalian hollow molding Market layout, but also to grasp the hollow molding market.
