一种在消声水池中使用的潜水泵的降噪装置
摘要：
本发明提供一种在消声水池中使用的潜水泵的降噪装置，包括隔离箱、第一侧面板、引水管、储水箱、第二侧面板、进水管、悬挂索、吊环、钢丝软管，隔离箱是缺一个侧面的正方体，所述第一侧面板位于隔离箱侧面，所述引水管位于隔离箱内部，所述储水箱是缺一个侧面的正方体，所述第二侧面板位于储水箱侧面，所述进水管位于储水箱外部，所述悬挂索位于隔离箱吊环和储水箱吊环之间，所述吊环位于隔离箱内侧的顶部和储水箱外侧的顶部，所述钢丝软管位于引水管和进水管之间。本发明利用储水箱的第一阶容许频率高，使得潜水泵因振动产生的低频辐射噪声不能传播至外面，利用悬挂索衰减储水箱与隔离箱之间的振动传递。
摘要（英）：

The invention provides a noise reduction device for a submerged pump used in an anechoic tank. The noise reduction device comprises an isolation tank, a first side plate, water diversion pipes, a water storage tank, a second side plate, water inlet pipes, suspension cables, lifting rings and wired hoses. The isolation tank presents a cube, one side face of which is nicked out. The first side plate is located on the side of the isolation tank and the water diversion pipes are located inside the isolation tank. The water storage tank presents a cube, one side face of which is nicked out. The second side plate is located on the side of the water storage tank and the water inlet pipes are located outside the water storage tank. The suspension cables are located between the lifting rings of the isolation tank and the lifting rings of the water storage tank. The lifting rings of the isolation tank are located on the top of the inner side of the isolation tank and the lifting rings of the water storage tank are located on the top of the outer side of the water storage tank. The wired hoses are located between the water diversion pipes and the water inlet pipes. The first order tolerable frequency of the water storage tank is high, so that the propagation of the low frequency radiation noise caused by the vibration of the submerged pump can be avoid. The vibration transmission between the water storage tank and the isolation tank can be decreased by the suspension cables.
