Frequency converter with synchronous motor in the extruder on the successful application of
Recently, Delta CH2000 series high performance vector frequency converter withsynchronous motor synchronization control scheme in a certain brand of plastic extrusion machine after successful application, personnel customer post test, the extruder discharging stability, fluctuation of current, speed stability, especially with thestep motor is more energy saving, low noise, stable running, the bearing capacitycharacteristics of large, long service life, less to the reducer, won the customer's high praise.
Mainly out of soft, hard polyvinyl chloride used in screw extruder, polyethylene plastic,with a variety of plastic machinery can be processing a variety of plastic products,such as film, pipe extrusion, pressing, pulling ribbon, can also be used to meltgranulation. As extrusion equipment host extrusion rate and pressure -- screw extruder extrusion machine became the main symbol of production efficiency and quality. In general, an extruder need to smooth in a certain range of speed regulation,with different kinds of plastic machinery production of different varieties of products. At the same time, plastic machinery is generally constant torque load, we must also have the torque to certain mechanical smooth starting at low startup. So not only canguarantee the stability of product quality, but also because of huge power consumption makes the production cost.
Delta have long been concerned about the environment and sustainable developmentissues, with professional experience in driving, control, power electronics field for many years, introduced plastic extruder synchronization solution, can effectively improve the production efficiency, improve product quality, reduce the cost of. In view of the current problems of plastic extrusion machine, configuration of the delta Cseries inverter synchronous motor control, using CH2000 90KW converter withsynchronous motor 80kW, delta technical personnel according to the customer's specific needs several computational experiments, and ultimately to achieve the best results.
This scheme is successfully implemented, plastic extrusion machine discharging stability, sound operation is greatly reduced, speed and fluctuation of current balance,improve the stability of product quality, but also greatly reduce the energyconsumption, to achieve energy efficiency, has won the trust of users.
