Development and Optimization of Mechanical Seal for Mud Pump with Large Flow,High Head and Super Large Shaft Diameter
The operation of"Tiankunhao"has greatly improved the construction efficiency of dredging engineering.However,at present,the L-type rubber seal adopted by"Tiankunhao"dredge pump is quickly worn under high discharge pressure,resulting in leakage and shutdown,which seriously affects the construction progress.To solve this problem,a method of replacing L-type rubber seal with mechanical seal is proposed.Through the calculation of technical parameters and the sealing part is simulated,the mechanical seal is designed and manufactured,and the performance of the mechanical seal is verified through two real ship tests.In order to solve the problem of short service life of dredge pump seal under large flow,high head,super large shaft diameter and high pressure,a new scheme is provided.
