This paper supplied a new way through variable frequency variable speed ( vfvs ) to change its output flow rate and adding a constant - pressure - drop valve, which could solve the defects in hydraulic pressure servo control system, such as low efficiency in control system, short life, poor ability in resisting pollution, low efficiency in driving system and flow rate, pressure pulse. and this way was proved to be effective
本論文針對傳統伺服控制系統效率不高、元件壽命短、抗污染能力差、驅動系統效率低、存在流量及壓力脈動等缺陷,利用先進的交流變頻調速技術改變液壓泵轉速的容積調速新方法,提出了在液壓系統中加一個定差減壓閥的新思路,較好地解決了液壓伺服系統存在的上述問題。Based on physical experiments, establishing mathematical model, carrying on theoretical calculations, and contrasting experimental results with theoretical ones, it turned out that under the same initiate flow rate, the quicker the closing of the ball valve, the longer the stable time when the liquid gets to vaporizing pressure, and the bigger the water hammer in water interception collision ; under the same closing velocities of the ball valve, the larger the initiate flow rate, the longer the stable time when the liquid gets to vaporizing preesure, and the bigger the water hammer in water interception collision
在試驗研究的基礎上,建立了含氣水錘數學模型,進行數值計算,並與試驗結果進行了比較,結果表明,在管道初始流量相同的情況下,球閥關閉速度越快,液體達到汽化壓力凡時穩定的時間越長,彌合水錘壓力也越大;在球閥關閉速度相同的情況下,管道初始流量越大,液體達到汽化壓力凡時穩定的時間越長,彌合水錘壓力也越大。When the electrohydraulic push rod works, if the external force suffered by the piston rod is more than the setting output torque, the piston moves to the end ; oil pressure in the oil pipeline increases rapidly to the setting value, the safety valve overflows rapidly, to achieve overload protection
