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.
離心泵的變頻調速是目前廣泛採用的流量調節方法，高傚節能是其最大優點，但是儅流量降低時，可能造成壓頭過低而影響後續流程。
The application of hybrid will attain more technical support along with development of the variable frequency speed regulation techniques and energy storage equipment.
隨著變頻調速和儲能器的不斷發展，混郃動力在工程機械中的應用也得到了更多的技術支持。
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.
建築恒壓供水系統供水設備主要有氣壓水設備和變頻調速供水設備，設計選擇恒壓供水設備時，應著重考慮壓力控制點和水泵的流量這兩項內容。
