本文提出了用绘制液力传动泥浆泵工况曲线来描绘其工作情况的方法。以4500米钻机为例,从分析其泥浆泵工作情况入手,求解出液力传动泥浆泵正常工作条件是:输入泥浆泵的功率应为其额定功率的88％,从变矩器输出轴至泥浆泵输入轴之间的减速比应使变矩器最高效率点的输出转速与泥浆泵额定冲数的0.94倍相对应。 This paper presents a method for plotting the performance of a fluid-driven mud pump by plotting its operating conditions. Taking a 4,500-meter drilling rig as an example, starting with analyzing the working conditions of its mud pump, the normal operating conditions of the hydraulic mud pump are as follows: The input power of the mud pump should be 88% of its rated power, from the torque converter output shaft to the mud The reduction ratio between the input shaft of the pump should allow the output speed of the torque converter at the highest efficiency point to correspond to 0.94 times the rated impulse of the mud pump.
