Description

Technical Field

[0001] The utility model relates to the technical field, in particular to a gas engine pipeline sealing detection tool. Background Art

[0002] The gas turbine pipeline refers to the pipeline system that supplies the fuel and air mixture to the combustion chamber of the gas turbine. It usually consists of a fuel delivery pipeline, an air delivery pipeline and other related pipelines. The main function of the gas turbine pipeline is to deliver fuel and air to the combustion chamber to ensure the correct proportion and stable supply of the fuel and air mixture. The design and layout of the pipeline need to consider the requirements of fuel and air flow, as well as the need to ensure safe and efficient operation of the gas turbine. The sealing of the pipeline is crucial for the normal operation of the gas turbine. First of all, the gas turbine pipeline needs to have good air tightness to ensure that fuel and air do not leak into the external environment. Fuel leakage may cause fire and explosion; while air leakage may affect the combustion process and combustion efficiency. In order to ensure the sealing of the gas turbine pipeline, common detection methods include pressure testing and leakage testing. The existing detection cannot tighten and clamp the gas turbine pipeline, which cannot ensure the smooth progress of the detection process. Utility Model Content
