为了进步泥浆的吸入浓度，进一步进步疏通效率，就产生了将泥泵移出机仓安装在绞刀架智商的设想，使泥泵尽可能靠近吸口，抽沙船让不受气蚀机能制约的水下泥泵获得较大的吸入浓度。，一般来说，首先想到的是进步泥浆泵的效率，多少年来泥浆泵研究职员为此付出了大量的辛勤劳动。但是，泥浆泵属杂质泵，其叶轮的结构特点，如叶片的进出口宽度相等，叶片数目少，通常为3-5片等，抽沙船决定了泥泵的效率作为主要追求目标，而把其目标追求转移到进步泥泵的吸入浓度上。由于从综合利益来讲，每进步5%的泥泵吸入浓度，所创造的效益，比每进步5%的泥泵效率所节省的用度要高的多，同时实现前者的难度要比实现后者的难度在一定程度上要小，由于目前泥泵效率已较高。
 

To progress the mud suction concentration, to further improve the dredging efficiency, the installation of the mud pump is removed from the cabin envisaged in the cutter frame IQ, the mud pump as much as possible near the suction mouth, pumping sand let constrained by the cavitation performance of underwater mud pump to obtain higher suction concentration. Generally speaking, the first thought is, improve the efficiency of the mud pump, mud pump for many years researchers have paid a lot of hard work. However, the slurry pump is impurity pump, the impeller structure characteristics, such as import and export of the blade is equal to the width and number of leaves less, usually 3-5 tablets, pumping sand determines the mud pump efficiency as the main goal, and the pursue the goal transferred to the progress of the slurry pump inhalation concentration. Due to in terms of comprehensive benefits, every progress of 5% of the mud pump inhalation concentration and create benefits, every progress of 5%, the efficiency of the mud pump can save more costs than to high. At the same time, the difficulty of the former than the latter difficulty in a certain extent to small, due to the current mud pump efficiency is higher.
