Vertical injection molding machine energy-saving technologies: the drive system

In the cost structure of vertical injection molding products, the traditional vertical injection molding machine pump motor power consumption ratio of 80% to 90% of the total power consumption of the device, at the cost of vertical injection molding products accounted for a considerable proportion. Energy saving vertical injection molding machine presses represents the development direction, who go ahead and who is bound to grab market opportunities. It is seen that, more energy-efficient production enterprises will develop into an important position.

Vertical injection molding machine energy-saving technologies, in fact encompasses three main perspectives: energy-saving injection molding technology; energy executive body; the most important energy saving drive systems, vertical injection molding machine that is powered systems.

With the current domestic-driven approach than the traditional, the structure replaced the three-phase AC induction motor with three-phase permanent magnet servo motor; fuzzy control method to complete servo motor with variable pump control coordinated to match the control method.

Vertical injection molding machine system total power loss is mainly controlled servo pump consists of two parts:

Power loss 1) of the motor, this loss includes copper loss and iron loss with the mechanical loss of the motor. This part of the loss can not be avoided in general, only use high-performance motors to reduce losses.

2) loss of hydraulic power systems. Since the adoption of the servo motor control system for variable pump. This part of the loss without throttling losses with overflow losses, but only with the volume loss, including losses due to leakage of hydraulic mechanical transmission system caused. So this total system power loss is very small, with better energy efficiency.
