摘要：为研究叶顶间隙的改变对半开式叶轮离心泵内部流场及性能的影响，选取某半开式叶轮离心泵进行全流道数值模拟。结果表明，不同相对间隙下叶轮内压力变化大体趋势一致，沿着叶轮进口到叶轮出口等压线周向呈均匀分布，且总压由叶轮进口向出口逐渐递增；随着相对间隙值增大，沿圆周方向叶轮流道内压力梯度逐渐减小，由于叶顶间隙增大使叶轮流道中高压流体沿着轴向的泄漏量增加引起叶片做功能力减弱，叶轮叶片出口处局部高压区逐渐减弱。在同一径向位置间隙层中靠近叶片工作面附近流体压力较背面大，且在叶片工作面与背面两侧间隙层存在较大的压力梯度。间隙层出口处存在局部高压区，随着间隙值的增大该局部高压区有所减弱，不同相对间隙值下相对速度沿径向均匀增大。叶轮轴向截面内存在着回流、绕流等不稳定流动，轴向截面中有明显的回流涡产生。叶片工作面（PS）高压流体横跨叶顶间隙从高压区向低压区泄漏并与相邻叶片背面流道主流相互掺混并在叶片背面（SS）形成较为明显的间隙泄漏涡（TLV），间隙泄漏涡的尺度随相对间隙值的增大而增大。

Abstract: In order to study the influence of the change of the tip clearance on the internal flow field and performance of the semi-open impeller centrifugal pump, a semi-open impeller centrifugal pump was selected for full-channel numerical simulation. The results show that the pressure changes in the impeller under different relative clearances are generally consistent, and are uniformly distributed along the isobaric line from the impeller inlet to the outlet, and the total pressure gradually increases from the impeller inlet to the outlet; As the relative tip clearance increases, the pressure gradient in the impeller flow path decreases along the circumferential direction. Due to the increase in the tip clearance, the leakage of the high-pressure fluid in the impeller flow path along the axial direction increases, which causes the blade to weaken its function. The impeller blade outlet The local high-pressure area gradually weakened. The fluid pressure in the tip layer near the blade pressure side in the same radial position is larger than that on the suction side, and there is a large pressure gradient between the tip between the blade pressure side and the suction side. There is a local high-pressure zone at the exit of the tip layer. As the tip clearance increases, the local high-pressure zone weakens, and the relative velocity increases uniformly in the radial direction at different relative tip clearances. In the axial section of the impeller, there are backflow and circumfluent unstable flows, and there are obvious backflow vortices in the axial section. The high-pressure fluid of the blade pressure side (PS) leaks from the high-pressure region to the low-pressure region across the tip clearance and blends with the main flow channel of the back surface of the adjacent blade and forms a more obvious tip leakage vortex (TLV) on the suction side (SS) of the blade. The size of the tip leakage vortex increases with the increase of the relative tip value.

Key words: centrifugal pump; semi-open impeller; tip clearance; numerical simulation; tip leakage vortex

Abstract: Based on the description method of inclined azimuth, the film thickness model considering radial profile is proposed. The radial surface profile of valve plate is measured using a surface testing machine and the ideal level, inner convex and inner concave cylinder are assumed. Then the steady lubrication model considering the radial profile is established and the law distributions of dynamic pressure are analyzed. The steady lubrication test rig is built for verifying the model. The following conclusions could be obtained. The dynamic pressure generating ability of inner convex cylinder is too poor to be used, and the inner concave cylinder has a strong dynamic pressure generating ability for valve plate design. Finally, the influence of surface concave distance on the steady-state lubrication characteristics is studied, and then the design suggestions are given.

Abstract: At present, mechanical crushing technology is usually used in the demolition of concrete buildings. This technology is not only easy to damage the surrounding buildings, but also pollute the environment. Ultra high pressure water jet demolition technology can effectively solve this problem and improve the work efficiency. The three-dimensional model of the driving mechanism of the manipulator arm of the ultrahigh pressure water jet breaking robot is established by virtual prototyping technology. AMESim is used to simulate and analyze the driving system of the manipulator arm to obtain the important working parameters. It can be seen from the simulation results that the mechanical arm and spray gun tray can reach the set position according to the preset speed by setting parameters, which lays a foundation for the optimization of the hydraulic system and structural parameters of the robot.

Abstract: The multi-directional rotation hydraulic parallel mechanism is widely used in the complex industrial scene, and its position detection system needs real-time and high-precision acquisition of position information. Aiming at the problem that the multi-directional hydraulic parallel mechanism has strong mechanical coupling and large position detection accuracy error under complex working conditions, based on the kinematics model of the multi-directional hydraulic parallel mechanism, a full order dynamic observer is constructed to observe the real-time state of the system by analyzing the information characteristics of the active sensing devices, so as to further study the multi-directional hydraulic parallel mechanism. The model of the position detection system of the driving parallel mechanism is reconstructed, and the minimum variance self-tuning and adaptive PID control methods are used to reduce the position detection error. The position detection system experiment platform is built. The experiment results show that the double control method can quickly improve the position detection accuracy of the position detection system and realize the control of the whole system Strong robustness.
