摘要
目的针对压力抗血栓装置中气泵流量压力性能检测需求,设计开发了一种气泵性能测试系统。方法该测试系统主要由气动回路系统和测试控制系统两部分组成。系统基于人机交互测试模块,以PC机为系统控制和测试核心,利用传感器实时检测气泵的压力和流量信号,通过数据采集卡将获得的压力和流量信号传送给PC机;基于LabVIEW开发环境编写测试系统软件,完成流量-压力曲线的绘制和显示,并结合数据分析判断气泵的性能是否正常;最后对SC3601PM型气泵进行性能测试,验证系统的可行性。结果实验所得的流量-压力拟合曲线与标准曲线的相关系数R均为0.9996,拟合曲线与标准曲线的最大绝对误差均在最大允许误差范围内。结论该测试系统可以较好完成气泵的流量压力性能的测试,并且该测试系统操作简便、精确度高且智能化,使气泵能更准确地应用于压力抗血栓装置中,推广和应用前景良好。
Objective A testing system of gas pump performance is designed and developed to meet the requirements of pressure flow pressure testing in pressure anti-thrombotic devices. Methods The test system is mainly composed of a pneumatic loop system and a test control system. Based on the human-machine interaction test module,the system takes PC as the core of system control and test,uses sensors to detect pressure and flow signals of the air pump in real time,and sends the obtained pressure and flow signals to PC through the data acquisition card. Test system software is written in the development environment of Lab VIEW,and the flowpressure curve is plotted and displayed,and whether the performance of the air pump is normal or not is judged by combining with the data analysis. Finally,the performance test of the SC3601 PM air pump is carried out to verify the feasibility of the system. Results The correlation coefficient R between the flow-pressure fitting curve and the standard curve obtained by the experiment is 0. 9996,and the maximum absolute error of the fitted curve and the standard curve are within the maximum allowable error range. Conclusions The experimental results show that the testing system can better finish the flow and pressure performance testing of air pump. The test system is easy to operate, high precision, and intelligent,which make the pump can be applied more accurately in the pressure anti-thrombotic equipment,andhas good prospects for promotion and application.
