Description
技术领域 technical field

背景技术Background technique
汽车的燃油供油系统是汽车燃油箱到发动机之间的供油管路系统，而燃油软管部分是供油系统中最薄弱且最重要的部件。燃油软管的密封性，尤其在接口处的密封性能是决定燃油软管稳定性的重要指标，一旦燃油软管的密封性能降低，则会对汽车的供油造成很大的影响。由于没有专门的燃油软管测试装置，通常对燃油软管的性能进行测试试验是采用集成式燃油供油系统试验台，这种试验台的功能多，可靠性较高，但是相应的该试验台的结构复杂，造价昂贵。2008年1月2日公告的CN201000395Y的中国实用新型专利说明书公开了一种汽车燃油供油系统寿命试验台，该试验台包括高低温保温防爆箱、试验燃油供给与流量、压力调节系统以及计算机测量机防爆电气系统，该试验台的功能集成度高，可靠性也较高，但是结构复杂，造价过高，在流水线式的汽车生产中，每一个环节的测试项目不同，所以不需要用到昂贵的燃油供油系统试验台，单独为燃油软管设计一种密封性能试验装置则非常必要。 The fuel supply system of a car is the fuel supply pipeline system between the fuel tank of the car and the engine, and the fuel hose part is the weakest and most important part of the fuel supply system. The tightness of the fuel hose, especially the sealing performance at the interface is an important indicator to determine the stability of the fuel hose. Once the sealing performance of the fuel hose is reduced, it will have a great impact on the fuel supply of the car. Since there is no special fuel hose testing device, the performance of the fuel hose is usually tested by using an integrated fuel supply system test bench. This test bench has many functions and high reliability, but the corresponding test bench The structure is complex and expensive. The Chinese utility model patent specification CN201000395Y announced on January 2, 2008 discloses a life test bench for an automobile fuel supply system, which includes a high and low temperature thermal insulation explosion-proof box, a test fuel supply and flow rate, a pressure regulation system, and computer measurement. Machine explosion-proof electrical system, the test bench has high functional integration and high reliability, but the structure is complex and the cost is too high. In the assembly line automobile production, the test items of each link are different, so there is no need to use expensive It is very necessary to design a sealing performance test device for the fuel hose separately. the
