Study and application of new sucking entrance of preventing sand and deposit from electrical submersible pump 新型潜油电泵防砂防垢吸入口的研究应用
Effect of Sucking Side Resistance on Maximum Flow Rate of Water Pump 吸入侧阻力对水泵最大流量的影响
The inner fluid in the steam pump was discussed through theoretical study, the mathematic model on sucking was educed, and the extension of the model was in conformity to the experimental value of steam eject pump in actual practice. 主要对蒸汽喷射泵内流体进行理论研究,推导出了蒸汽喷射泵的抽气数学模型,并给出了该模型与实际蒸汽喷射泵实验值的符合范围。
On the basis of compared and analytical results of all sorts of pumps, the suction condition of self-sucking sliding-vane pump is described. It is pointed out that the sucking device of the pump must meet the needs of sucking ability. 在与各类泵对比分析的基础上,论述了滑片自吸泵的吸入条件,指出滑片自吸泵吸入装置必须满足吸入能力的要求。
Monitoring sucking condition of mud pump with wavelet analysis of vibration signal 用振动信号的小波变换监测泥浆泵的吸入状态
Mud particle size has little effect on sucking efficiency of dusupant; When mud concentration increased, the velocity of outlet will decrease. And, to keep the rated flow, the mud pump pressure must be increased. 泥浆颗粒大小对吸泥效率的影响不大;当泥浆浓度升高时出口速度会减小,要保持额定流量必须增加泥泵的排泥压力。
