摘要
提出了一种新型的同步回转式混输泵,介绍了该混输泵的结构特点与工作原理.在对其关键运动部件建立动力学模型的基础上,研究了该混输泵的动力学特性,分析了主要结构参数对泵的动力学性能的影响,并对样机进行了功率特性测试.研究结果表明:同步回转式混输泵具有结构简单、运转平稳、制造成本低等优点;转子和油缸之间的相对角速度低于转子角速度的10%;滑板受力随相对偏心距和长径比的减小而减小,转子轴承与油缸轴承的载荷随相对偏心距的增大和长径比的减小而减小;在0.5～2.5MPa的工作压力范围内,样机的实测功率与理论计算值的相对偏差为17.3%～35.1%,其中摩擦功耗所占比例较大,需进一步改进.
A new synchronal rotary multiphase pump（SRMP）is proposed and its structural characteristics and working principle are described.With the dynamic model established for the key moving parts,the dynamic characteristics of the pump and the influence of main structural parameters on the dynamic performance are investigated.The power input of a prototype of the SRMP is tested experimentally.The results show that the pump has the advantage of simple structure and smooth running.The relative angular velocity between the rotor and the oil cylinder is less than 10% of the rotor angular velocity.The forces on the pump slide vane decrease with the decrease of the relative eccentricity and the slenderness ratio.The loads on bearings decrease with the increase of the relative eccentricity or the decrease of the slenderness ratio.Additionally in the working pressure range of 0.5-2.5 MPa,the deviation of the power input tested and calculated is in the range of 17.3%-35.1%,the friction loss in the prototype occupies a large part of the total power consumption.It seems that the pump needs to be improved further.
