瑞典勒威尔衣用机械公司生产出一种新型的自动水轮泵。这种水轮泵只要在流速不低于0.4m/s水深不低于0.25m 的渠道或小河的水流中就可以自动抽水。它的最大特点是,当水的流速发生变化时,能自动调节旋转叶轮的角度来保证机泵抽水。这种水轮泵已有从小到大的16种系列规格的产品,供不同的流速和水深选用。 Sweden Lerweier clothing machinery company to produce a new type of automatic water pump. This kind of hydraulic pump can automatically pump water only in the water flow of the channel or small river whose flow velocity is not lower than 0.4m / s and not lower than 0.25m. Its most important feature is that when the water flow rate changes, can automatically adjust the angle of the rotating impeller pump to ensure that the pump. This type of water pump has grown from 16 to the largest series of specifications for different flow rates and depth of selection.
