在航道整治、水利疏通及江河湖泊的管理工程中，絞吸式挖泥船是主要的施工設(shè)備之一。
如何進(jìn)步絞吸式挖泥船的綜合效益，一般來(lái)說(shuō)，首先想到的是進(jìn)步泥漿泵的效率，多少年來(lái)泥漿泵研究職員為此付出了大量的辛勤勞動(dòng)。但是，泥漿泵屬雜質(zhì)泵，其葉輪的結(jié)構(gòu)特點(diǎn)，如葉片的進(jìn)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(jìn)步泥泵的吸入濃度上。由于從綜合利益來(lái)講，每進(jìn)步5%的泥泵吸入濃度，所創(chuàng)造的效益，比每進(jìn)步5%的泥泵效率所節(jié)省的用度要高的多，同時(shí)實(shí)現(xiàn)前者的難度要比實(shí)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。
為了進(jìn)步泥漿的吸入濃度，進(jìn)一步進(jìn)步疏通效率，就產(chǎn)生了將泥泵移出機(jī)倉(cāng)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(jī)能制約的水下泥泵獲得較大的吸入濃度。
In waterway regulation, water conservancy and dredging of rivers and lakes management project, the cutter suction dredger is one of major construction equipment.

How the comprehensive benefits of progress of cutter suction dredger. Generally speaking, first thought is progress of mud pump efficiency, how many years to mud pump researchers paid a 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.
為了進(jìn)步泥漿的吸入濃度，進(jìn)一步進(jìn)步疏通效率，就產(chǎn)生了將泥泵移出機(jī)倉(cāng)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(jī)能制約的水下泥泵獲得較大的吸入濃度。
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.
