一、如果购买的胶管不是抽砂专用胶管，而是吸引胶管，或者其他用途的胶管。使用过程中，会出现脱层。漏钢丝，漏气，吸扁。直至报废。所以选对专用胶管是主要的。

1. If the rubber hose purchased is not a special hose for sand extraction, it attracts rubber pipes, or other uses. In the process of use, delamination will occur. Leakage of steel wire, gas leakage, suction flat. Until discarded. So the choice of special rubber hose is the main.

二、使用中尽可能不要打死弯，因为钢丝骨架容易变形，变形后，抽砂的过程中，容易吸扁。

Two, do not kill the bending as much as possible, because the steel skeleton is easy to deform, after the deformation, the process of sand pumping, easy to draw flat.

三、使用中不要经常挪动胶管。在地上拉动胶管，容易损坏表皮。影响使用寿命。

Three. Do not often move the hose in use. Pulling the hose on the ground is easy to damage the skin. It affects the service life.

四、抽沙过程中，如果有硕大的石头，请尽量换用好质量胶管，帘子布层数厚的，内层胶用最好质量的耐磨胶，加重耐磨度。钢丝使用厚度应在4.0以上。

Four, in the process of sand pumping, if there are huge stones, please try to replace the quality hose with the thickness of tire cord cloth, the inner layer glue is made of the best quality wear-resistant glue, and the abrasion resistance is increased. The thickness of steel wire should be more than 4.

五、不耐磨跟胶质有关，和内层胶有关，和使用中的强度有关。

Five. The non wear resistance is related to the colloid, which is related to the inner glue, and is related to the strength in the use.
