Description
技术领域technical field
本实用新型涉及汽车零部件领域，特别涉及一种尿素罐气密性试验台。The utility model relates to the field of auto parts, in particular to a urea tank airtightness test bench.
背景技术Background technique
气密性对于尿素罐的技术要求很高，一旦尿素罐发生泄漏，会导致尿素溶液漏出，挥发成气味刺鼻的氨气，同时导致后处理系统失效无法对尾气进行有效反应，致使排放超标。因此，在尿素罐出厂前都要进行气密性检测。Airtightness has high technical requirements for urea tanks. Once the urea tank leaks, the urea solution will leak out and volatilize into pungent ammonia gas. At the same time, the after-treatment system will fail to respond effectively to the exhaust gas, resulting in excessive emissions. Therefore, the air tightness test must be carried out before the urea tank leaves the factory.
目前，现有的尿素罐气密性检测设备采用传统的冒泡法，工作人员需要用手动夹具将尿素罐固定在水槽中，然后用气枪往罐内加压，同时观测尿素罐周边是否有气泡析出，且要根据气泡数判断其泄露程度，操作者工作强度大，容易疲劳，易造成漏检。At present, the existing urea tank air tightness testing equipment adopts the traditional bubbling method. The staff needs to fix the urea tank in the water tank with manual clamps, and then use an air gun to pressurize the tank, and at the same time observe whether there are bubbles around the urea tank Precipitation, and the degree of leakage must be judged according to the number of bubbles. The operator has a high work intensity and is prone to fatigue, which may easily cause missed inspections.
