Air in dredge pumps will greatly reduce the efficiency of the pumps during dredging operations.The paper analyzes how the air is formed in dredge pumps,how the air affects the working efficiency of dredge pumps,and how the air can be removed from the pumps.The paper also describes in detail the composition and working mechanism of dredge pumping system on Trailing Suction Hopper Dredger,Wanqingsha.The results show that the de-aerating system can enhance the dredging efficiency both theoretically and in actual practice.
