Description
技术领域technical field

背景技术Background technique
轴流泵是一种应用非常广泛的通用机械，国内要求非常巨大，主要适用于低扬程、大流量的场合，如灌溉、排涝、船坞排水、运河船闸的水位调节，或用作电厂大型循环水泵。传统轴流泵具有以下优点： 1）双重机械密封，可靠的防止漏水，大型泵因轴向力大，采用专用推力轴承，结构设计合理，润滑充分，散热良好，轴承使用寿命长；2） 泵站规模小，土建、建筑结构简单，投资大为减少，可减省泵站工程造价的30%-40%；3）机泵一体化，安装维修省时省工，节省费用；4）机泵潜入水中，冷却条件好，机泵运行平衡性好，稳定、振动小、噪音低。Axial flow pump is a kind of general-purpose machinery with wide application, and the domestic requirements are very huge. It is mainly suitable for occasions with low lift and high flow, such as irrigation, drainage, dock drainage, water level adjustment of canal locks, or as a large circulating water pump in power plants. . Traditional axial flow pumps have the following advantages: 1) Double mechanical seals, which can reliably prevent water leakage. Large-scale pumps use special thrust bearings due to their large axial force, with reasonable structural design, sufficient lubrication, good heat dissipation, and long service life of the bearings; 2) Pumps The scale of the station is small, the civil engineering and building structure are simple, and the investment is greatly reduced, which can save 30%-40% of the construction cost of the pumping station; 3) The machine-pump integration saves time, labor and cost for installation and maintenance; 4) Machine-pump Submerged in water, the cooling condition is good, the pump operation is well balanced, stable, small vibration, low noise.
由于轴流泵在排涝、船坞排水、运河船闸的水位调节等江海场合的广泛应用，然而江海中有大量的鱼类生物，鱼类等在轴流泵吸力作用下进入轴流泵的内部，但现有的传统轴流泵叶轮的高速旋转使鱼类很难幸免于难。为了降低轴流泵工作时鱼等河海生物的死亡率，本发明根据轴流泵的特点，设计出一种新型的轴空轴流泵，当鱼类经过轴流泵时，在轴流泵的轴空部分经过，保证了鱼等河海类生物的生命安全。Due to the wide application of axial flow pumps in river and sea occasions such as waterlogging, dock drainage, and water level adjustment of canal locks, there are a large number of fish organisms in the river and sea, and fish enter the interior of the axial flow pump under the suction of the axial flow pump. The high-speed rotation of the existing traditional axial flow pump impeller makes it difficult for fish to survive. In order to reduce the mortality rate of fish and other river and sea organisms when the axial flow pump is working, the present invention designs a new type of axial flow axial flow pump according to the characteristics of the axial flow pump. The hollow part of the shaft passes through, ensuring the life safety of fish and other river and sea creatures.
