WATERJET SYSTEM WITH ROPE CUTTER

摘要

PURPOSE: A water jet system with a rope cutter is provided to prevent the halt or failure of an impeller by cutting a unwanted object, such as a rope or a fishing net, with a cutter before the unwanted object is caught in the impeller. CONSTITUTION: A water jet system with a rope cutter(100) comprises an inflow pipe(10), an impeller shaft(20), an impeller(30) and a nozzle(40). The water flows into the inflow pipe through an inflow port(11). The impeller shaft is rotated by an engine. The impeller is installed at the impeller shaft. The water flows back by the impeller and is sprayed back through the nozzle to generate driving force. A cutter is installed at the front end of the impeller and is rotated by an impeller rotation shaft. The cutter cuts the unwanted material flowing into the inflow pipe.
