泵壓力提交
英文
the pumpressure to be confirmed-
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。Apart from these, the paper also proposes several improvements for pump control, which include changeable cut off control that can prevent several kinds of relief loss of hydraulic system, cross sensing control of pump that can enlarge the variable working range and compound control that combine two kinds of valve control method together
此外，還提出了幾種泵控改進方案，其中包括可防止多種系統溢流狀態的可變壓力切斷控制、能增大泵的變量工作范圍的交叉功率傳感控制以及將兩種閥控策略結合在一起的復合控制技術。The peculiar mechanical character about pumping liquid concrete is discussed. based on the supposition that the ability of transferring hydraulic pressure of liquid concrete is orthotropic and the friction forces exists between concrete and steel tube, the pressure formulas of liquid concrete and the allotting formulas of deadweight are reasoned out. a new method is brought forward for allotting deadweight of liquid concrete during simulation analysis in pumping - core - concrete construction phase, which improves the calculation precision
在探討泵送液態混凝土的特殊的力學性質基礎上，在假定液態混凝土傳遞壓強能力為正交各向異性、混凝土與鋼管壁之間的存在有摩擦力的前提下，推導出液態混凝土壓強公式和自重荷載的分配公式，提出了在進行鋼管內混凝土灌注過程的施工模擬分析時處理液態混凝土自重荷載分配的合理方法，從而提高施工模擬分析的計算精度。
