Abstract

In order to reduce the vibration of vane pump in the process of crude oil exploitation, the operating impact caused by sudden change of acceleration should be eliminated as much as possible. The mathematical model of the stator internal cavity curve was obtained by deducing the octagonal curve equation. The transition curve was fitted by MATLAB software. In order to verify the dynamic performance of the vane pump, an experimental scheme was designed, and the variable speed and variable pressure experiments of the vane pump were carried out. The experimental results showed that at the speed of 500 r/min, the lift reached 23.14 m and the flow reached 2.44 m³/h, which met the design requirements of low speed; the vane pump had certain requirements for external pressure load, and its maximum value could not exceed 0.5 MPa. If this value was exceeded, the vane pump would lose its self-priming performance; with the increase of rotating speed, its flow and noise would increase; as the pressure load increased, the outlet flow increased first and then decreased, and the noise generally increased, but it rose slowly after the pressure load was greater than 0.25 MPa, and the flow in the pump gradually approached 0.At this time, the noise of the pump mainly came from the friction between the vane and the stator. The research results provide a reference for reducing the vibration and noise of the vane pump and further optimizing the structure of the vane pump.

八次方定子曲线对叶片泵动态性能的影响

为了降低叶片泵在原油开采过程中的振动，应尽量消除其由于加速度突变而造成的运行冲击。通过推导八次方曲线方程，得到定子内腔过渡曲线的数学模型。采用MATLAB软件对过渡曲线进行拟合。为了验证该叶片泵的动态性能，设计了实验方案，进行叶片泵变速和变压实验。实验结果表明：在500 r/min转速下，扬程达到23.14 m，流量达到2.44 m³/h，满足了低速设计要求；叶片泵对外部压力负载有一定的要求，其最大值不能超过0.5 MPa，若超过此值，叶片泵将失去自吸能力；随着转速的提高，其流量和噪声增大；随着压力负载增大，流量呈先上升后下降的趋势，噪声总体呈上升趋势，但在压力负载大于0.25 MPa后上升有所缓慢，泵内流量逐渐趋近于0，此时泵的噪声主要来源于叶片与定子的摩擦。研究结果为减小叶片泵的振动和噪声以及叶片泵结构的进一步优化提供了参考。
