配流盤
英文
port plate-
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出流量脈動，造成輸出流量脈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型尖槽進行了理論計算，繪制出p - t圖線，分析了它的不足，並對原有v型尖槽進行了優化設計，得出了v型尖槽的最佳幾何尺寸：配流盤平面上的v型尖槽的兩邊的夾角為12 . 3 ，槽長5mm ，槽的橫截面為等邊三角形。In this paper, a safe, reliable, and intellectual control plan is provided aiming at the heat charge for dwelling district, which contains epigynous machine responsible for data processing and hypogynous mahcine responsible for unlocking the valve, by means of serial communication between them, combining homemade three - channel valve, to adminstrate the charge data and the valve efficiently. the main idea is based on the homemade three - channel valve. the vavle is locked at peacetime, while it is opened with the help of open tool and a water flow in the caliduct. as soon as the flow stops, the valve locks automatically. the open tool has data in its memory, and implement function by lcd and keyborad. so it can identify data and drive motor, to open the valve intellectually. the epigynous machine database manage system administrator the dweller information, standard heat charge and payment infomation etc, including store, configure, query, print etc, then store in the memory of open tool. as a result, the plan can do well in the experiment
