变频器在挤出机操作中的应用原理

发布日期:2017-10-21 00:00 来源:http://0558gs.com 点击:

挤出机属于工业设备,拥有着复杂的结构和繁复的技术轴承。变频器作为变频器领域的领导品牌,多年来致力于深研变频器领域!现在我们要思考的是在挤出机应用过程中,变频器能够发挥什么作用呢?

  要想弄明白变频器的应用原理,那么我们就先要搞清楚螺杆挤出机的工作原理!固态粒子原料首先从漏斗喂入,然后被加热塑化或熔化,螺杆旋转将熔化为胶态的原料推向挤出机的出口,挤出机出口装有特定的模具,决定了最终产品的形状。塑料薄膜、塑料管、型材和化纤等产品都可以用挤出机生产。

  交流驱动方法其实并不难,它和变频器的工作原理息息相关!仅在数年以前交流驱动还不能提供直流驱动那么优异的性能,而且价格还很贵。但随着近年功率电子器件和微处理器技术的快速发展,交流控制理论的提出以及实际交流控制软件的具体完善,交流驱动技术在很多应用领域有了比直流驱动更佳的成本效益。目前的FC302系列变频器用在挤出机上有比直流驱动更好的转速控制性能和转矩响应速度,开环转速控制精度优于0.5%,闭环转速控制精度优于0.1%。

  一般工厂里挤出机耗能要占到总耗能相当大的比例,FC300驱动器有比直流驱动器和其他通用变频器的输入谐波电流小很多,保证总输入功率因数大于0.9,因此无需放大工厂供电变压器和电缆的容量。
