variable frequency and speed regulation

基本解释

To this problem, the variable-frequency speed regulation and flow regulation split-ranging coordinated control of the centrifugal pump for energy saving is given.
离心泵的变频调速是目前广泛采用的流量调节方法，高效节能是其最大优点，但是当流量降低时，可能造成压头过低而影响后续流程。
The application of hybrid will attain more technical support along with development of the variable frequency speed regulation techniques and energy storage equipment.
随着变频调速和储能器的不断发展，混合动力在工程机械中的应用也得到了更多的技术支持。
Air-pressure water equipment and frequency variable speed regulation equipment are the main furnishment. Pressure control point and flow of water pump should be considered during designing.
建筑恒压供水系统供水设备主要有气压水设备和变频调速供水设备，设计选择恒压供水设备时，应着重考虑压力控制点和水泵的流量这两项内容。
