Emotron泵用低压范围可调速驱动器问世

    瑞典专业从事电机和驱动器生产的Emotron公司最新研发出VSA/VSC系列产品,该产品可以在低压范围下调节电动机的速度。该公司说，这种驱动产品能为泵类，风扇类，压缩机，混合机器等产品提供高级应用服务。该系列产品适用功率范围是0.18-7.5千瓦，完全包含在Emotron公司的0.18-1500千瓦的功率范围里。


Emotron公司说，VSA/VSC驱动器能够有效的开始和停止，减少了水的冲力和其他的损害的危险系数，这就缓解了对于昂贵的马达控制阀的需求。这种控制器同样采用了马达控速，以其达到所需要的水准。这种产品在与节流阀阀或者调节阀对比中体现出了良好的节能效果。当机器不需要运行就能保持需要的压强时，一种嵌入式“休眠系统”会发挥作用，暂停机器的相关任务。

该类产品能都适应和应用于不同的负荷条件下，例如，对于泵类、风扇类、压缩机和混合机器不同的情况，该产品有八种不同的预设程序以适应它们。

Variable speed drives for low power applications


Swedish motor and drive specialist Emotron has developed VSA/VSC, a range of compact variable speed drives for low power applications. The drives are equipped with several advanced functions for pumps, fans, compressors, mixers and cranes, the company says. The series is suitable for motors of 0.18-7.5 kW, and completes the Emotron range which now covers motor powers of 0.18-1,500 kW.

The VSA/VSC drives have efficient starts and stops, which eliminate the risk of water hammer and other damage, lessening the need for expensive motor-controlled valves, Emotron says. The drives also adapt motor speed to the level required, saving energy when compared to throttling valves or dampers. A built-in sleep function pauses the motor when it does not need to be run in order to keep up the required pressure.

Different load types can be handled by the drives, using, for example, constant torque for cranes and mixers and square torque for pumps and fans, and the drives have eight programmable pre-set speeds, the company says.
