深水三危场合下的切割技术

Cutting technology in deep water and dangerous conditions

讨论了高压水射流技术具有的"软、冷"切割特点,分析了前、后混合磨料射流的优缺点及在深水条件下的使用问题和配套设施。随着技术的成熟,高压水射流水下切割技术将越来越受到人们的欢迎。

The cold and soft cutting performances of highpressure water jets are analyzed in the paper. The advantages and disadvantages of abrasive suspension jets, premixed abrasive water jets and abrasive entrained water jets are discussed, and the application of the cutting technology and its necessary accessories are put forward. With the development of highpressure water jets, the jet cutting technology becomes more and more popular in submerged condition.
