Syringe pumps are very useful tools to ensure a constant and pulsation-free flow rate, however usability is limited to batch processes. This article shows an open-source method for manufacturing a push pull syringe pump, valid for continuous processes, easy to build, low-cost and programmable. The push-pull syringe pump (PPSP) is driven by an Arduino nano ATmega328P which controls a NEMA 17 in microstepping via the A4988 stepper driver. The Push-Pull Syringe Pump setup is configurable by means of a digital encoder and an oled screen programmed using C ++. A PCB was designed and built to facilitate the assembly of the device. The continuous flow is guaranteed by four non-return valves and a dampener, which has been sized and optimized for use on this device. Finally, tests were carried out to evaluate the flow rates and the linearity of the flow. The device is achievable with a cost of less than 100 €.
注射泵是确保流速恒定且无脉动的非常有用的工具，然而其可用性仅限于间歇过程。本文展示了一种用于制造推拉式注射泵的开源方法，该方法适用于连续过程，易于构建，成本低廉且可编程。推拉式注射泵（PPSP）由Arduino nano ATmega328P驱动，它通过A4988步进驱动器以微步控制一个NEMA 17。推拉式注射泵的设置可通过数字编码器和使用C ++编程的OLED屏幕进行配置。设计并制造了一块印刷电路板（PCB）以方便设备的组装。四个止回阀和一个阻尼器确保了连续流动，该阻尼器的尺寸已针对此设备的使用进行了调整和优化。最后，进行了测试以评估流速和流量的线性度。该设备的制造成本低于100欧元。
