| Product Name: V5-IS (asynchronous servo injection molding machine is mainly used for new machine) | | | Price: | | manufacturer: | | Add Time: 2013/4/28 15:56:52 | |  | | | Three ways of energy-saving injection molding machine:
1, V/F inverter and induction motor, variable frequency energy-saving, no feedback system, low control accuracy, reduce the efficiency of production, which belongs to the elimination of type.
2, vector drive + synchronous motor + speed and pressure feedback, namely synchronous servo energy-saving, energy-saving effect is good, installation of complex, high price, high maintenance cost.
3, the asynchronous motor vector drive + + current feedback, namely energy-saving asynchronous servo, simple installation, good power saving effect, low maintenance cost, high ratio of performance to price.
Asynchronous servo introduction
For energy-saving injection molding machine, servo is realized closed-loop feedback control system, fast dynamic response, high control precision.
Servo is the advanced stage in the development of the inverter, inverter is the mother of servo. Innovation asynchronous servo, ingenious combination of advantages of variable frequency energy-saving technologies and synchronous servo energy-saving technology, but also overcomes their disadvantages, based on lifting machine production efficiency, good power saving effect, and has the absolute price advantage. After quantitative pump injection molding machine supporting asynchronous servo, with the new competition, the whole industry, subversive significance.
Asynchronous servo energy-saving principle
Injection molding machine electricity consumption in the main oil pump motor, so reducing the pump motor power consumption is a key energy-saving injection molding machine. In the hydraulic system, quantitative pump, motor in 50Hz high-speed operation, fuel supply pump is basically unchanged, the actual traffic demand is far greater than the working condition of injection molding machine, high pressure oil surplus through the relief valve is returned to the oil tank, there is a huge waste of energy. But oil and motor oil pump speed is proportional to, so we can reduce the speed of the motor in each action, the actual traffic demand fuel supply and injection molding machine oil pump is consistent, virtually eliminates overflow phenomenon, the motor can stop cooling, in order to achieve the purpose of energy saving. | | | Clicks: 12816 |  |
