针对仓储中心不仅储存品种多、数量大的电驱动燃油泵,而且缺乏通用综合型的电驱动燃油泵检测设备,致使燃油泵库存期满后无法实现性能检测,只能返回承制厂处理的现实难题。该文首先简要介绍了电驱动燃油泵的功用和工作原理,在此基础上,详细说明了流体测试系统的的基本组成和特点,利用平板电脑、PLC、智能调节阀和比例调节阀技术设计了该装置的电控系统,给出了电控系统的硬件、软件和操作界面的实现方法。实际应用表明:该测试装置能够满足电驱动燃油泵性能的测试要求,测试精度和效率高,可靠性强,结构科学合理,操作界面友好,可为产品性能检测提供有力的技术支持。
For storage center not only store a large variety and quantity of electric drive fuel pump, and lack of general-purpose electric drive fuel pump testing equipment, resulting in the expiry of the fuel pump inventory can not be achieved after the performance test, only to return to the reality of factory processing problem. In this paper, the function and working principle of electric fuel pump are briefly introduced. Based on this, the basic composition and characteristics of fluid testing system are described in detail. The design of the testing system is based on the technology of tablet PC, PLC, intelligent regulating valve and proportional regulating valve The electronic control system of the device gives the realization of the hardware, software and operation interface of the electronic control system. The practical application shows that the test device can meet the test requirements of the performance of the electrically-driven fuel pump. The test precision and efficiency are high, the reliability is good, the structure is scientific and reasonable, the operation interface is friendly, and the test device can provide powerful technical support for product performance testing.
