The working principle of full-automatic hollow molding machine is the quantitative pump system driven by AC servo motor, which is an advanced high-performance energy-saving system developed in recent years. It solves the performance problem of frequency control technology by adjusting the speed of hydraulic pump and slow response speed. At the same time, due to its operation characteristics, the utilization efficiency of power is improved. Because the servo motor does not adopt permanent magnet structure, and because the torque and inertia are closely matched, the pulsating torque is eliminated under the low inertia rotor coordination, and it 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 keep a very low torque ripple.


At very low speed, it can also have a large fixed torque area to achieve constant flow output. The hydraulic system basically does not need cooling water. The plastic hollow products with long cooling and solidification time can save up to 80% energy. During refrigeration, the motor is in the stop state, which can give full play to the energy saving characteristics and improve the precision control performance of the system. The maximum speed of AC servo motor can reach 40oor / min. Theoretically speaking, the displacement of the matching hydraulic pump can be selected according to the maximum speed, and the displacement hydraulic pump smaller than the ordinary system can be selected to reduce the application cost of the hydraulic pump in the system.
