【摘要】：在泵控马达调速系统中,泵和马达在工作时不断的吸油和排油以及油液有可压缩性等原因,使得系统流量产生脉动、压力不稳定,所以马达输出轴转速产生较大的波动,从而影响回转工件的加工质量。通过在马达轴安装惯量盘,预在系统工作时使惯量盘吸收流量脉动,系统流量波动减小、压力稳定性提高,马达轴转速波动降低。经过实验验证了该方法的可行性,说明在马达输出轴上加装惯量盘能够减小系统流量的脉动,使马达轴转速更加稳定。研究结论为在实际工况中解决流量脉动对马达转速的影响提供可靠方法。
[Abstract]:In the pump control motor speed regulation system, the pump and motor continuously absorb and drain oil while working, and the oil has compressibility, which causes the system flow rate to fluctuate and the pressure is unstable, so the speed of the motor output shaft is fluctuated greatly. Thus, the machining quality of the rotary workpiece is affected. By installing the inertia disk in the motor shaft, the inertia disk absorbs the flow pulsation while the system works, the system flow fluctuation decreases, the pressure stability increases, and the motor shaft speed fluctuation decreases. The feasibility of this method is verified by experiments. It is shown that adding inertia disk to the output shaft of the motor can reduce the pulsation of the system flow rate and make the rotation speed of the motor shaft more stable. The results provide a reliable method for solving the effect of flow pulsation on motor speed in actual working conditions.
