摘要
采用图谱设计法设计具有水力推进器的行走式水下清淤机 ,目的是为了适应水下复杂的土层条件。计算显示 ,装有一个水力推进器后可增加推力 30 0N左右 ,结果令人满意。经实验测试 ,装了水力推进器的清淤机能明显改善工作情况 。
In this paper, the under water purge machine with propeller is designed by using a collection of illustrative plates in order to fit with complex earth condition under water. The calculating result shows that one propeller will increase the force by about 300N. It well meets the requirement. After testing at the site, the purge machine with propeller is obviously advanced to increase its capacity and was approved by inspective authority.
