　　根据中国民用航空总局《运输类飞机适航标准》（CCAR-25-R3）条款的要求，飞机压力加油系统的工作情况必须通过地面试验进行验证。然而ARJ21-700在压力加油试验中，飞机加油接头入口压力无法达到试验要求的0.343MPa，试验被迫中止。本文通过对加油车加油流程、原理等进行分析，提出了调节加油车管内压力控制阀和拆除加油接头处稳压阀的办法来提高飞机接头入口油压，最终成功解决了飞机加油接头入口油压过低的问题。

According to the requirements of the provisions of "transport category airplane airworthiness standards" of Civil Aviation Administration of China, the pressure refueling system of aircraft must be veriifed by ground tests. However, the pressure of refueling joint entrance of ARJ21-700 cannot meet the pressure which must get to 0.343MPa in tests of pressure refueling, so that the test is suspended. In order to increase the pressure of refueling joint entrance, this paper analyses the process and principle of fuel truck’s refueling system, adjusts the pressure control valve of fuel truck’s pipe and removes the regulator valve and eventual y the problem is successful y solved.
