中文摘要:
      针对以波纹管蓄能器和隔膜泵为基本元件的喷码机墨路循环系统中存在的压力脉动现象,通过对关键部件隔膜泵(含隔膜、吸入液阀、排出液阀等)与波纹管蓄能器的分析建立墨路循环系统的液压仿真模型,分析了波纹管刚度、阻尼孔孔径等重要参数对脉动吸收效果的影响,获得吸收压力脉动的波纹管的最优参数,通过试验验证了仿真结果,压力脉动抑制的关键在于波纹管的刚度必须与隔膜泵工作压力合理匹配。
英文摘要:
      In reaction to the phenomenon of the pressure pulse within the Continuous Inkjet ink circulatory system, used the bellows as energy storage and diaphragm pump as a primary components, build the hydraulic simulation model of ink circulatory system via analyzing the critical components: diaphragm pump (including membrane, the suction valve and the outlet valve) and bellows. By analyzing the impact of pressure pulse restraint under the different bellows stiffness and the inner diameter of the restrictor, the optimal parameters of the bellows components were determined. The simulation results were verified by experiment on the test bench. The key point of the pressure pulse restraint is the proper matching of the bellows stiffness and the working pressure of the diaphragm pump.
