1.改进的必要性若沥青洒布车导热油管路出现漏油问题,会引起管路烧坏、导热油起火,可造成重大经济损失和安全事故。因此在新的沥青洒布车下线后设置了检测工序,对导热油管路进行气密性试验,以检测导热油管路是否渗漏。此外,沥青洒布车投入施工生产后,按照使用手册的规定必须每隔1个月检测1次导热油管路是否产生泄漏。上述检测的具体方法如下;首先将沥青洒布车开到设有固定气源的地方,用气管、压力表、接头、密封件将气源 1. The need for improvement If oil leakage occurs in the HTF pipe of asphalt sprinklers, the pipe will be burned out and the HTF may catch fire, which may cause significant economic losses and accidents. Therefore, the new asphalt sprinkler off the assembly line set up the testing process, the conductance test of the heat-conducting oil pipeline to detect heat-conducting oil pipeline leakage. In addition, asphalt sprinkler into construction after production, in accordance with the provisions of the user manual must be detected once every 1 month HTF pipeline leaks. The specific methods of detection are as follows: Firstly, asphalt spreading truck is opened to a place with fixed gas source, gas source, pressure gauge, joint and seal
