In the view of practice a determination method of maximum braking oil pressure for braking system during the operation of JK mine hoister is put forward. 从实用的角度提出了JK型矿井提升机在工作过程中制动系统最大制动油压的确定方法。
The mathematical analysis shows that, with disregarding local head losses and by means of different simplified rigid models, the calculated results of the maximum pressure in a pressurized pipe system containing trapped air mass are equal to and independent of the initial length of the water-column. 通过数学分析证明,在不计局部水头损失时,目前常用的几种简化刚性数学模型的最大气压计算结果相等,并与管道内初始充水段长度无关。
The Determination of Maximum Oil Pressure for JK Mine Hoister Braking System JK型矿井提升机制动系统最大油压的确定
Never exceed the maximum pressure or flow ratings of any component in your system the component with the lowest rating determines the maximum performance available from your system. 不要超过你所选择的水泵系统中任何部件的最大压力或流量的额定值;额定值最低的部件决定了水泵系统的最佳可用性能。
The total cubage of the pressurized-type water supply unit depends on the ratio of maximum dynamic and static water pressure of the fire protection system as well as the net dilatation cubage of the water in the system. 消防气压给水设备的总容积是由消防系统最高动水压与静水压的比值、系统的水净膨胀容积决定的。
