為了進步泥漿的吸入濃度，進一步進步疏通效率，就產(chǎn)生了將泥泵移出機倉安裝在絞刀架智商的設(shè)想，使泥泵盡可能靠近吸口，抽沙船讓不受氣蝕機能制約的水下泥泵獲得較大的吸入濃度。，一般來說，首先想到的是進步泥漿泵的效率，多少年來泥漿泵研究職員為此付出了大量的辛勤勞動。但是，泥漿泵屬雜質(zhì)泵，其葉輪的結(jié)構(gòu)特點，如葉片的進出口寬度相等，葉片數(shù)目少，通常為3-5片等，抽沙船決定了泥泵的效率作為主要追求目標(biāo)，而把其目標(biāo)追求轉(zhuǎn)移到進步泥泵的吸入濃度上。由于從綜合利益來講，每進步5%的泥泵吸入濃度，所創(chuàng)造的效益，比每進步5%的泥泵效率所節(jié)省的用度要高的多，同時實現(xiàn)前者的難度要比實現(xiàn)后者的難度在一定程度上要小，由于目前泥泵效率已較高。
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.
