机械化清淤是保证池塘养殖业可持续发展的重要手段,在池塘不排水的情况下进行机械化清淤作业称为水下清淤,漂浮式水下清淤是最常用的一种。而泥浆泵是漂浮式清淤机械——清淤船的重要部件,要提高清淤船的工作效率,必须保证泥浆泵的工作泥浆浓度。研究证实,提高泥浆泵工作泥浆浓度的综合措施有:选用耐高温油浸石棉绳作为泵的密封材料以及改进泵的内部结构,使泥浆轴向进、径向出通道流畅;改进吸泥盘设计;稳定泵的工作条件——即控制船速在3km/h左右。
Mechanized dredging is an important means to ensure the sustainable development of pond aquaculture. Mechanized dredging in the case of undrained ponds is called underwater dredging, and floating dredging is the most commonly used method. The mud pump is a floating dredging machinery - an important part of the dredging ship, to improve the working efficiency of the dredging ship, we must ensure that the slurry pump working mud concentration. The research proves that the integrated measures to improve the mud concentration of the mud pump are as follows: selecting the asbestos rope with high temperature resistant oil as the sealing material of the pump and improving the internal structure of the pump to make the mud flow smoothly in and out of the axial direction; improving the design of the mud suction plate ; Stable pump working conditions - that control the speed of 3km / h or so.
