  1. Fluid noise mainly comes from out put pulsation of rate of flow, the main reason of out put pulsation of rate of flow is the instant high pressure return flow that obturation cubage produced when the big round curve pressure transition. the v trough on the port plate can reduce the fluid noise. in this paper, the author based on the acting of dam a river and condensability of liquid and used matlab language as tool to calculate the v trough on the original port plate and drew out the p - t diagrammatic curve and analyzed its shortcoming and improved the design of original v trough and got that the best size of its angle was 12. 3 and its length was 5mm and the cross section was an equilateral triangle

    流體噪聲主要來源於輸流量動,造成輸流量動的主要原因是閉死容積在大圓弧段壓力切換時產生的瞬時高壓迴流,在配流盤上開設v型尖槽可降低因高壓迴流而引起的流體噪聲,本文以截流作用和液體的可壓縮性為理論依據,以matlab語言為工具,對原配流盤上的v型尖槽進了理論計算,繪制p - t圖線,分析了它的不足,並對原有v型尖槽進了優化設計,得了v型尖槽的最佳幾何尺寸:配流盤面上的v型尖槽的兩邊的夾角為12 . 3 ,槽長5mm ,槽的截面為等邊三角形。
