| 1， 水面使用的漂浮吸沙胶管。此种软管要求可以自浮在水面上，由于矿坑的落差比较大（100米）和输送的距离比较长，所以此部分的软管要有很高耐压力，根据测算设计压力为25公斤/平方厘米。要考虑到浮船会随水位的升降而上下移动和波浪引起横向位移。其内部结构与离岸使用的吸沙胶管一样不同之处是在软管外面加装了浮体。 1. Floating sand suction hose for water surface. This kind of hose is required to be able to float on the water surface. Because the drop of the mine pit is relatively large (100m) and the conveying distance is relatively long, the hose in this part should have high pressure resistance. According to the calculation, the design pressure is 25kg / cm2. It should be considered that the floating ship will move up and down with the rise and fall of the water level and the wave will cause the lateral displacement. The internal structure of the hose is the same as that of the sand suction hose used offshore. 2， 离岸使用的吸沙胶管采用高耐磨橡胶生产，管壁厚度为22毫米，内胶层厚度为7毫米，含胶量为75%，比同等厚度的Q235钢管耐磨性能要好。采用12层D3纤维帘线增强层，设计工作压力25公斤/平方厘米，可以满足2000米管线的压力要求。螺旋钢丝骨架线径为5.5毫米，要考虑到在停泵的情况下矿浆倒流产生虹吸现象，抽沙泵要加装回止阀。外胶层选用抗老化的EPDM橡胶。 2. The sand absorption rubber pipe used offshore is made of high wear-resistant rubber. The thickness of the pipe wall is 22 mm, the thickness of the inner rubber layer is 7 mm, and the rubber content is 75%, which is better than that of Q235 steel pipe with the same thickness. With 12 layers of D3 fiber cord reinforcement layer, the design working pressure is 25kg / cm2, which can meet the pressure requirements of 2000m pipeline. The wire diameter of the spiral steel wire skeleton is 5.5mm. In consideration of the siphonage caused by slurry backflow when the pump is stopped, the sand pump shall be equipped with a check valve. The outer rubber layer uses anti-aging EPDM rubber. |
