What are the technical difficulties in manufacturing large conveyors?

What are the technical difficulties in manufacturing large conveyors?

对于现在市场上的输送机产品来说，主要的还是中小型的输送机机械，大型的输送机产品在技术上有一定的难度，安徽永生机械股份有限公司对于目前大型输送机产品的技术总结可以看出，主要的技术难点有以下几个方面。 一、功率器件的选型，目前通用型变频器在国内外都已经是非常成熟的产品，我们没必要再去对其内部构造及原理做更多的研发工作，所应做的就是对功率元器件及主机驱动部分选型。 二、功率器件的散热，散热是防爆变频器遇到的最大难题。在变频器内部：逆变模块是发热最多的器件，据专家诂计，它约占整个变频器所有散热量的一半；整流模块也是发热相当多的，它所散发的热量约占整个变频器的45％；而剩下的5％则是电解电容、充电电阻、均压电阻以及印制板上的发热元件等所散发的热量。据了解，变频器的热功耗大约为其额定功率的2％～3％，也就是说若电机的额定功率为400kW，其发热量大约为8～12kW。那么在一个密闭的防爆腔里怎样能把这些热量及时、迅速地传递出去并散发掉，这是防爆变频器能长期正常运作的关键。 三、电磁兼容(EMC)，变频器由主回路和控制回路两大部分组成，但由于主回路的非线性(进行开关动作)，变频器本身就是谐波干扰源，所以对电源侧和输出侧的设备会产生影响。输送机的技术难点，安徽永生机械股份有限公司相信在未来技术高度发展的时代里，会得到很好的解决，安徽永生机械股份有限公司也将不断努力，争取为输送机的发展做出贡献。 大家如有需要优质输送机的，可以电话联系0556-6203328，同时也可以进入我公司网站“安徽永生机械股份有限公司”www.ys-machine.com进行详细了解。
