The live water washing equipment for electrified railway insulators utilizes the running gap of the train to realize the live washing operation, which greatly improves the work efficiency and greatly reduces the labor intensity. In this equipment, the structure and machining accuracy of the nozzle directly affect the flushing effect. Since the degree of scattering and turbulence of the water flow ejected from the existing nozzle is relatively large, the flushing force of the ejected water column is relatively small, which affects the flushing effect.
