摘　　要：随着石油、天然气资源勘探开发等领域的快速发展，挖沟机的研制成为了水下作业装备领域的研究热点。抽吸扬泥系统是水力冲射式挖内机设计的关键技术之一，论文针对水力冲射式挖沟机的作业特点，采用了环形多喷嘴射流泵作为抽吸扬泥系统的核心工作部件；同时结合射流基本理论，对抽吸系统的主要技术参数进行了初步设计，并对其性能参数进行了计算，为挖沟机总体设计和主要设备选型提供了重要依据。With rapid development of offshore oil and gas resources exploration, underwater trencher has become a research hotspot in the field of underwater operation equipment. Mud suction pump system is one of the key technologies in the design of hydraulic jet trencher. Based on the operation characteristics of hydraulic jet trencher, annular multi-nozzle jet pump is used as the core part of mud suction system. Combined with basic jet theory, main technical parameters of pumping system are designed and the performance parameters are calculated, which provides an important basis for overall design and main equipment selection.
