摘要针对汽车电动燃油泵手工检测操作不便,数据精度、效率低等问题,以某款汽车燃油泵为研究对象,研制一种基于LabVIEW环境和数据采集卡的汽车电动燃油泵性能测试系统。该系统通过NI-USB 6210数据采集卡采集燃油压力、燃油流量、油泵工作电压和工作电流等参数,以LabVIEW编制的上位机界面实现控制参数的设定、油泵性能评价、数据显示、存储、历史记录查询等功能。实验结果表明,该系统的测试时间较传统检测方法缩短了 90%以上,燃油泵性能的测试精度和检测效率均有大幅提高。

AbstractA set of oil pump performance testing system based on automotive oil pump is designed for the problems of complex operations,data inaccuracy and low efficiency in the handle testing of oil pump.With the help of LabVIEW environment and data acquisition card,this testing system tests the automobile oil pump performance with NI-USB 6210 data acquisition card to collect fuel pressure,fuel flow,pump working voltage and current parameters.PC interface is compiled by LabVIEW to realize the control parameters setting,pump performance evaluation,data display,storage,query and other functions based on historical records.The experimental results show that the testing time of this system is reduced by 90% with dramatically improved accuracy and efficiency compared with the traditional test method.

电动燃油泵是汽车发动机燃油供给系统中的关键部件,其作用是提供足够的燃油压力和流量,满足发动机各种工况对燃油的要求[1-2]。燃油泵性能的好坏直接影响发动机的工作性能[3],因而必须对燃油泵的输油性能进行检测。目前,国内电动燃油泵的种类较多,但性能检测技术却相对落后,主要采用人工读表检测和真空度法[4-5]。

人工手动检测法的测量精度差、效率低、稳定性不高,不适合电动燃油泵大批量生产检测。而真空度法缺点是燃油泵容易过热损坏。……
