variable vane pump 中文意思是什麼
variable vane pump
解釋
變量葉片泵-
In chapter four, according to the analysis on the boundary theory and velocity field of main fluid zone of two - phase fluid pumps, the parameter equations of vane ' s modular curve of centrifugal pump are given, which contact the boundary " layer and eular theory of two - phase fluid pump by the fixing angel of vane as variable and leading into the velocity coefficient a. the results show that, in designing process of vane ' s modular curve of centrifugal pump, the determination of the total shape and parameters relates the flow properties of two - phase fluid and output ability of pump, or the design of the modular curve of centrifugal pump is the kernel of hydraulic design
第四章依據固液兩相流泵的邊界層理論及對主流區速度場的分析，給出了離心泵葉片型線的參數方程；它是以葉片安裝角為參變數，以引入的速度系數k _ v作為中間因子，將兩相流泵的邊界層理論和歐拉理論聯系起來? ?它說明了這樣一個事實，在離心泵葉片型線的設計過程中，它的整個形態或參數的確定都關繫到兩相流體的流動特性和泵的輸出能力，或者說，離心泵型線的設計是其水力設計的核心。 -
Based on the theory of boundary layer and analysis of the velocity field of main flow, the thesis also derives the vane shape equation. in the equation, （ angle of pump vane ） is variable parameter, （ velocity coefficient ） is introduced as medium factor, which connects the theory of boundary layer with the eular theory. it provides a valuable reference for the designation of vane of pump
基於離心泵葉片邊界層理論和對主流區速度場的分析，給出了離心泵葉片型線參數方程，它以葉片角為變參數，引入速度系數作為中間因子，將邊界層理論和歐拉理論聯系起來，並在離心泵葉輪的設計過程中統一起來，能夠在設計中就根據實際的需要防止或控制過流表面的邊界層的分離。
