加油机计量精度测试装置的研发

Experimental Study on Measurement Accuracy of Refueling Machine

针对加油机长周期使用下计量性能的测试要求,研发了加油机流量计老化试验和计量精度测试装置。装置由智能控制系统、检定计量装置、测试液循环系统等组成。通过设定加油机老化总量、阶段性老化累积量、单次加油量以及间歇时间等参数,实现对加油机进行长周期老化试验和精度检定。对某两个厂家的加油机流量计进行实验测试,结果表明经500 000 L的加油量老化试验后,流量计仍保持了很好的测量精度;该实验装置能够实现加油机流量计老化和精度测试流程,并获得有效而可靠的数据。

Aiming at the test requirements of measuring performance of refueling machine under long period application, a refueling machine flowmeter aging test and measurement accuracy testing device were developed, which consisted of intelligent control system, calibration and measurement device, and the test liquid circulation system. By setting the refueling machine aging amount, staged accumulation of aging amount, single refueling volume, and intermittent time and other parameters, the long period aging test and accuracy verification of refueling machine were realized. The refueling machines from two manufacturers were tested by aging experiment, after the refueling amount of 500000 L, the flowmeter still maintained a good measure accuracy. The test results showed that by the experiment platform,the flowmeter aging and the accuracy of testing process could be implemented with the valid and reliable data obtained.
