A new type of mud pump with high flow, high pressure, compactness and light weight is designed for truck mounted water well drill rig, tackling the difficulty in mud pump matching.

为车装水文水井钻机设计大流量、压力、体积、质量的新型泥浆泵，解决其泥浆泵配套难的问题。

By the study,the authors find that the pressure distribution is characterized by "nonlinear" and the motion of pump valve is the same,too.

对有杆抽油泵泵阀运动规律的研究和确定抽油泵泵阀筒内液体压力的分布是提高抽油机井系统效率研究的关键性课题。

Applied to adjust the casing pressure for ESP wells, it automatically discharges through the bleeding valve, the casing gas into oil/gas manifold, for the purpose of controlling the reasonable submergence depth of ESP intake, and preventing the shut-down of ESP due to gas lock or under-load. This not only ensures the normal pump operation but also enhances the pump efficiency and production rate.

常用于电潜泵套管压力调节，套管气通过放气阀排入输油管汇，以控制合理的电泵吸入口沉没度，防止潜油电泵发生因气锁现象的发生导致的欠载停泵，保证电泵的正常运行，提高泵效及产量。

"The delivery rate of two-cylinder piston pump with the patented concrete valve can be adjusted from 2 cubic meters/h to a maximum of 34 cubic meters /h, for pumping pressures of up to 65 Bar ."

气缸摘要：在往复泵中旋转气缸，吸气阀和排气阀是非常重要的部件且是易损部件，它们工作的好坏直接影响往复泵的极限压力、抽气速率、功率消耗以及运行的可靠性。

The twin vortex at the tip clearance of hub side and the asymmetric recirculation at wall of inlet duct are also observed. 4 The mass-weighted average of flow parameter at inlet and outlet of every passage of impeller changes with different positions. In addition to the above, with the unsteady method, the head rise, shaft power and efficiency have been predicted well.

再次，采用整机非定常计算准确预测了三种工况下部分流泵的扬程、轴功率和效率；发现了叶轮进出口质量加权平均的速度、压力、动量矩的宏观不变特性；蜗壳内流动的非定常性对部分流泵的外特性有重要的影响。
