商业建筑中的泵驱动器

优化舒适性,可靠性和能源效率

Danfoss AC凭借多个泵划分的控制功能,智能保护功能和无传感器泵控制功能,可以优化舒适性和能源效率,并保护系统中的驱动器,电动机和设备。它们还确保在泄漏或管道破裂的情况下确保优化的液体供应。专用功能包括:

嵌入式多泵控制器

泵级联控制器在所有泵上均匀分布操作小时。因此,单个泵的磨损将减少到最低限度,从而大大延长了其寿命和可靠性。

干泵保护和曲线检测的末端

如果泵在不产生所需压力的情况下运行,则驱动器会引起警报或执行其他预编程的动作。例如,当井运行干燥或管道泄漏时,就会发生这种情况。

PI控制器的自动调整

自动调整使驱动器能够监视系统对驱动器进行更正的反应。驱动器从中学习并计算P和I值,因此快速恢复精确和稳定的操作。

流动补偿

靠近泵的压力传感器提供了一个参考点,使压力在系统的放电端保持恒定。驱动器不断调整压力参考,以遵循系统曲线。这种方法既节省能源并降低安装成本。

无/低流量检测和睡眠模式

在低或没有流动的情况下,驱动器进入睡眠模式以节省能量。当压力降至预定义的设定点以下时,驱动器会自动启动。与连续操作相比,此方法降低了能源成本和设备的磨损,并有助于延长应用程序的寿命。

管道填​​充模式

在受控管道填充的所有应用中都有用,例如供水系统。管道的受控(闭环)填充可防止水锤,爆裂的水管或吹出洒水头。管道填​​充模式可用于垂直和水平管系统。

初始/最终坡道

初始坡道可快速加速泵至最低速度,从正常坡道接管的地方。这样可以防止泵上推力轴承的损坏。最终的坡道从最低速度下降到停止的最低速度。

流动确认

流动确认监视器可保护设备免受意外的停止。监视器与外部设备(例如阀门或流动开关)持续通信。如果来自外部设备的信号会耗尽,则监视器会将AC驱动器拖动。

润滑前/润滑

一些机器需要在操作前后的机械零件进行润滑,以防止损坏并减少磨损。在润滑过程中,某些设备必须保持活跃,例如排气风扇。为了实现这一目标,前润滑剂功能支持向外部设备发出信号,以在用户定义的时间段执行特定动作。可用的配置:“仅润滑油”,“ Pre&running”和“ Pre&running&Post”。

免费编程的文本

此功能支持对应用程序的多功能改编。使用基于内部或外部事件的可自由编程的文本消息,以获取信息,警告或警报。该函数还支持基于事件的操作,例如启动阀门触发的坡道。

高级最低速度监视器

当泵速度太低时,潜水泵可能会遭受冷却和润滑不足。高级最低速度监视器通过监视和调整行程速度以减少磨损来保护泵。维护的停机时间最小,不需要外部监控设备。

检查阀坡道

止回阀坡道在停止泵时阻止水敲击,通过确保慢速泵速度向下倾斜,就像止回阀球几乎关闭一样。

无传感器泵控制

无传感器控制是一种分配泵控制方法,该方法可输入液压系统电阻的平均HVAC系统加热或冷却需求,然后调整泵的速度以平衡满足需求,并最大程度地减少所使用的能量。无传感器泵曲线嵌入驱动器中。
