  6. Among them the flow pulse is more standing - out, which is the main reason of its not more widely used. because high flow pulse will lead to the worse of the smooth movement of hydraulic motor and pipe, also cause pressure pulse which lead to a high noise, and give the destructive damage to the axial, bearing, valve, the connect of pipe etc. how to make the flow pulse low has become the research of scholars of many country

    其中流量脈動問題顯得尤其突出，它嚴重製約著齒輪泵的應用，因為泵的流量脈動大，不僅會使液壓缸運動的平穩性、液壓馬達回轉的均勻性性變差，而且會引起壓力脈動，進而使管道、閥門乃至整個系統振動（特別是在共振時） ，並發出很強的噪聲，這對軸、軸承、管接頭及密封都有破壞性影響。
  7. The simulation shows that the valve throttle area should be little as possible but must be more than 40 % of pipe section area ; when the total length of pipe is same, and the flow quantity is enough, pipe before primary valve should be thin and long, and the pipe after primary valve should be thick and short, the upriver and downriver small pressure fluctuation will badly lead to waterdrammer pressure rising, and spending more time in establishing pressure and flow quantity

    模擬表明，閥門過流面積在滿足大於管道截面積40 %的條件下應盡可能小;在管道總長一定並滿足流量要求的條件下，主閥前應採取長而細的管道，閥后則應採用短而粗的管道;上下游微小的壓力波動都會嚴重增大開關閥門引起的水擊，並使壓力、流量的建立需要更長的時間。
