In general, it is believed that, the impingement angle of particles in the hydraulic machinery is small.

醫(yī)學 一般而言，大多數(shù)人相信在液壓的機械裝置里粒子的角度影響是很小的。

Even though actual data for impingement angle are not available so far, it can be considered as spectrum of low impingement angles when the water is flowing almost parallel to the surface.

雖然目前沒有什麼實際的資料可以驗證粒子角度的影響，但當水的流動跟表面幾乎是平行時，角度影響的幅度相對的會比較低欧美国产精选。

Then, the method to estimate cavitation erosion characteristic of high pressure piston plunger pump by analyzing impingement angle on outlet of throttling groove is put forward. That is, to hold the impingement angle range of 30°～60°as appraisal criterion of cavitation erosion characteristic on high pressure hydraulic plunger pump.4 The throttling characteristic of hydraulic control valve is studied by CFD calculation and experiment.

最后，提出了一個通過分析節(jié)流槽出口處的射流方向來評價高壓軸向柱塞空蝕特性的空蝕評價方法在线视频福利第一网，即將節(jié)流槽出口的射流角范圍30°～60°作為評價高壓軸向柱塞泵空蝕特性的標準91三级片在线视频观看。4對液壓控制閥的節(jié)流特性進行了CFD數(shù)值計算和試驗研究。
