初始的抽沙龙头都是采用了角式密封，并且在进行抽沙的过程中经常会造成进入空气，造成泵空。主要的原因就是抽沙龙头的角式密封不够牢固，会造成空隙，造成整个首杀龙头的不可使用。将角式密封改为圆环密封，并采用了圆箍进行固定，提高了泵的真空度和仇杀效率。.叶轮的安放角度由原来的27°改为现在的22°，降低了叶轮的角度；  2.将原来的两段弧型叶轮改为对数螺线型叶轮；3.提高了叶轮对水的束缚作用，加大了包角，用以增加叶片长度。由原包角度数为65°调整为82°。改进包角，加大了过流金属面积，从而降低了磨损强度。改装后通过实验可以提高使用寿命和抽沙效率水上管路系统固定浮体采用钢管焊接成固定的浮桥，灵活度不够，抽沙船移动极其不便。根据现场施工特点，固定浮体改为专用配套的聚苯乙烯工程泡沫塑料浮体，大大的增加了水上管路系统布置的灵活度，提高了抽沙船转移的机动性原设计抽沙船输沙管路系统全部采用6英寸（150mm）管道向集浆池里输送泥浆。由于管径小，阻力损失大，较大的束缚了砂砾泵的送浆能力，没有能够大的发挥砂砾泵的抽沙、输沙效率。为了提高管路输浆效率与管路系统工作稳定性，对输浆管路系统的改进包括调整管径与采用管路专用的固定系统“聚苯乙烯工程泡沫塑料”浮体

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
