河北程跃泵业的泥浆泵性能参数

date.png 2019-07-31 17:47:24

泥浆泵性能的两个主要参数为排量和压力。排量以每分钟排出若干升计算﹐它与钻孔直径及所要求的冲洗液自孔底上返速度有关﹐即孔径越大﹐所需排量越大。要求冲洗液的上返速度能够把钻头切削下来的岩屑﹑岩粉及时冲离孔底﹐并可靠地携带到地表。地质岩心钻探时﹐一般上返速度在0.4~1米/分左右。泵的压力大小取决于钻孔的深浅,冲洗液所经过的通道的阻力以及所输送冲洗液的性质等。钻孔越深﹐管路阻力越大,需要的压力越高。随着钻孔直径、深度的变化﹐要求泵的排量也能随时加以调节。在泵的机构中设有变速箱或以液压马达调节其速度﹐以达到改变排量的目的。为了準确掌握泵的压力和排量的变化﹐泥浆泵上要安装流量计和压力表﹐随时使钻探人员瞭解泵的运转情况﹐同时通过压力变化判别孔内状况是否正常以预防发生孔内事故。、

The two main parameters of mud pump performance are displacement and pressure. The displacement is calculated by discharging several litres per minute. It is related to the diameter of the borehole and the required speed of the flushing fluid from the bottom of the hole. That is to say, the larger the diameter of the hole, the larger the displacement required. It is required that the upward and backward velocity of the flushing fluid can flush the cuttings and rock powder from the drill bit off the bottom of the hole in time and carry them to the surface reliably. When drilling for geological cores, the upward and backward velocities are generally about 0.4-1 m/min. The pressure of the pump depends on the depth of the borehole, the resistance of the passage through which the flushing fluid passes and the nature of the flushing fluid transported. The deeper the borehole is, the greater the resistance of the pipeline and the higher the pressure required. With the change of borehole diameter and depth, the displacement of pump is required to be adjusted at any time. The pump mechanism is equipped with a gearbox or a hydraulic motor to adjust its speed in order to achieve the purpose of changing displacement. In order to accurately grasp the changes of pump pressure and displacement, flowmeters and pressure gauges should be installed on mud pumps to keep drillers informed of pump operation at any time. At the same time, pressure changes can be used to judge whether the condition in the hole is normal or not in order to prevent accidents in the hole.
