Nozzle design and test of water seal lubrication system for large gate

In order to solve the problem of poor lubrication effect of water seal in large gate, three kinds of nozzles with different structures are designed. In order to further explore the best installation form of nozzle, the water flow animation of 3# nozzle at different angles, different installation positions and different water pressures was simulated by using Blender and ANSYS-CFD, the best lubrication effect is obtained when the distance from water seal section is 40mm and the water pressure is 0.5MPa. The experimental results show that the model test results of 3# nozzle are basically consistent with the simulation results, and the optimum 3# nozzle has the best lubrication effect. The research results can provide technical reference for the optimization transformation of water seal lubrication and the design of water seal lubrication for the same type of gate.
