初始的抽沙龍頭都是采用了角式密封，并且在進行抽沙的過程中經常會造成進入空氣，造成泵空。主要的原因就是抽沙龍頭的角式密封不夠牢固，會造成空隙，造成整個首殺龍頭的不可使用。將角式密封改為圓環密封，并采用了圓箍進行固定，提高了泵的真空度和仇殺效率。.葉輪的安放角度由原來的27°改為現在的22°，降低了葉輪的角度； 2.將原來的兩段弧型葉輪改為對數螺線型葉輪；3.提高了葉輪對水的束縛作用，加大了包角，用以增加葉片長度。由原包角度數為65°調整為82°。改進包角，加大了過流金屬面積，從而降低了磨損強度。改裝后通過實驗可以提高使用壽命和抽沙效率水上管路系統固定浮體采用鋼管焊接成固定的浮橋，靈活度不夠，抽沙船移動極其不便。根據現場施工特點，固定浮體改為專用配套的聚苯乙烯工程泡沫塑料浮體，大大的增加了水上管路系統布置的靈活度，提高了抽沙船轉移的機動性原設計抽沙船輸沙管路系統全部采用6英寸（150mm）管道向集漿池里輸送泥漿。由于管徑小，阻力損失大，較大的束縛了砂礫泵的送漿能力，沒有能夠大的發揮砂礫泵的抽沙、輸沙效率。為了提高管路輸漿效率與管路系統工作穩定性，對輸漿管路系統的改進包括調整管徑與采用管路專用的固定系統“聚苯乙烯工程泡沫塑料”浮體
Crown-drilling pumping sand:
Sharon initial pumping head seals are based on the angle, and during the process of pumping sand often result into the air, causing the pump empty. The main reason is that the head of the corner salon pumping seal is not strong enough, it will cause the gap, causing the entire first kill leading unusable. The angle ring seal to seal, and uses a round hoop fixed to improve the efficiency of the vacuum and pump vendetta. . Placement angle of 27 ° from the original impeller changed now 22 °, reducing the impeller angle; 2. the original two curved impeller to linear logarithmic spiral impeller; 3. improve the impeller on the water bound effect, increasing the corners, to increase the blade length. Original package for 65 ° angle adjustment for the number of 82 °. Improved wrap angle, increasing the overcurrent metal area, thereby reducing wear and tear strength. After modification experiments can improve the life and efficiency of water pumping sand floating body fixed piping system used in the steel welded into a fixed pontoon, flexible enough, pumping sand movement is extremely inconvenient. According to the construction site characteristics, fixed float dedicated to projects supporting the polystyrene foam floating body, greatly increasing the flexibility of the water piping system layout, improved mobility shift pumping sand pumping sand sediment original design piping systems all using 6 inches (150mm) to set the pulp slurry pipeline pond. Due to the small diameter, high pressure loss, the larger the shackles of the gravel slurry feed pump capacity, there is no maximum to play gravel pump pumping sand, sediment transport efficiency. In order to improve the efficiency of slurry pipeline transport and pipeline system job stability, the improvement of the slurry pipeline transport system including adjusting the diameter of the fixed piping system using a dedicated "polystyrene foam project" floating body
