根据建立的函数关系式,可直接计算泵的容积效率和所需的泵的体积排量,或迭代求出地面产液量。
Based on the established functional relation, the V_e and the required P_d can be calculated directly, or the total liquid production rate at surface can be calculated indirectly.
利用上面的原理,对BB - B80油泵进行齿形设计,同时以“单位体积排量最大”为目标对此泵进行优化设计。
With used of principle which is upside, we redesign the gear form of BB-B80 oil pump. At the same time, proceed optimum design for the goal of "swept capacity of unit volume".
它具有径向液压力平衡、流量均匀性好、噪声低、排量大、体积小等优点。
The strong points of the compound gear pump are balanced hydraulic pressure of radius, uniform of flow rate, small volume, large displacement and low noise and so on.
