用于采矿和矿物加工的起重机驱动器

安全、精确的起重性能

在采矿和矿物加工中，起重机(如矿吊、桥式起重机和龙门起重机)是生产和维护工作中必不可少的设备。

对于矿井提升机来说，起重机的运动是完全垂直的。关键因素是在高扭矩的精确控制和快速响应的机械制动器的安全考虑。交流驱动器提供恒转矩控制和快速响应，以满足这些要求。

对于移动起重机和龙门起重机，负载通过缆绳从一个抓取装置上悬吊，并像钟摆一样工作。这些摇摆荷载是一个安全隐患，并在起重机结构上施加额外的应力。解决方案是在电机的输入端使用交流驱动器紧密地控制运动。

丹佛斯提供配备起重机性能优化功能的驱动器，以服务于不同的起重机应用。

优越的矿井提升机可靠性

矿井提升系统由五个主要部分组成:提升机、输送机、钢丝绳、竖井和井架。这些组件中的每一个都需要广泛的设计考虑。

在矿井提升机的运行中，电动机正在逐渐取代柴油电动机和涡流电动机。电机可由交流驱动器控制，提供最佳的安全性和优越的提升性能。早期的技术使用直流电提升驱动，利用晶闸管，也称为固态转换器。然而，现代矿井提升机是用交流电工作，由交流驱动器(也称为vfd或vsd)进行变频控制。丹佛斯的交流驱动器在静止和运行条件下可靠地保持精确和恒定的扭矩。它们还确保了机械刹车在安全危急情况下的快速反应。

快速响应矿井卷绕系统

矿井卷绕系统的主要组成部分是带绳布置的滚筒;气动刹车;带推力器制动器的齿轮箱;收卷电机及控制台。

丹佛斯驱动在闭环应用中提供快速响应和准确的性能，这在起重应用中至关重要。驱动器与PLC和控制台的简单接口使过程操作非常顺利。该驱动器通过对故障的高速响应，提高了矿井提升机的安全性。

在滚筒提升机施工中。滚筒位于离轴一定距离的地方。这个距离通常被称为飞行角。绳子缠在鼓上。一般来说，鼓式提升机被认为比其他类型的提升机更灵活。单滚筒提升机和双滚筒提升机均采用交流驱动控制，提高了性能。

做生意

丹佛斯驱动提供来自我们的驱动专家的个人建议和应用设计，以支持原始设备制造商、系统集成商和工业用户。我们还为硬件和软件提供定制的解决方案，实现无缝集成，并提供一系列功能，优化整个系统。
