spool valve 中文意思是什麼
spool valve
解釋
短管閥-
Then pid flow rate control algorithm is introduced. all experiments made in this chapter are about measuring the valve parameters according to spool positions, single actuator flow rate control by the calculated flow rate feedback control method, free flow rate dividing control under the sufficient pump discharge flow rate situation, proportion flow rate dividing and flow rate dividing based on meter - in flow rate feedback control method under insufficient pump discharge flow rate situation. the results of all experiments proved that the method presented in this thesis is an effective way to overcome the unreasonable flow rate dividing when simultaneously operating multi - actuators with different inertia loads
第四章介紹了多執行器復合控制實驗系統和實驗方法；介紹了實驗採用的流量控制的pid演算法；並測定了執行器控制閥和閥芯位移相關的系數；做了單個執行器計算流量反饋流量控制、流量足夠情況下多執行器流量任意分配、流量不足情況下多執行器按比例調節流量分配和多執行器進油側流量反饋分流控制實驗；通過實驗說明了論文提出的分流控制方法能實現大小慣性負載復合操作時的合理分流。 -

In order to overcome the disadvantages of servo valves and the spool valves, the fast hydraulic system controlled by the fast on - off valve is researched which uses the on - off valves as the pilot valves. they are used to control the opening and closing of the logic valves, thus they can control the pressure and the flow. so they can control the movement direction and the velocity of the piston
為了克服伺服閥和滑閥的不足，本文所研究的基於快速開關閥的快速液壓系統採用快速開關閥作先導閥，控制邏輯閥的開啟和關閉，從而控制液流的通斷和壓力的高低、流量的大小，以實現對活塞運動方向、速度的控制。 -
