本文提出了射流泥浆泵装置的设计理论和方法。结合葛洲坝水利枢纽船闸深井排泥的要求,设计和研制了射流泥浆泵装置。试验表明:该装置性能达到设计要求,同时验证了本文提出的理论和设计方法。它们具有较大的普遍性,可供水利、水电、交通等部门设计射流泥浆泵装置时使用。 This paper presents the design theory and method of jet mud pump device. Combined with the requirement of deep well sludge discharge of Gezhouba Dam, the jet mud pump was designed and developed. The experiment shows that the performance of the device meets the design requirements and the theory and design method proposed in this paper are validated. They have greater universality and can be used by water conservancy, hydropower and transportation departments to design jet mud pump devices.
