1988年10月在意大利维罗纳举办的水产养殖展览会上,西德生产的一种新颖奇特、功能多样的增氧机受到了极大关注。该增氧机形似一个巨大的塑料蘑菇,总重量41公斤,直径1300毫米,所用电压可选380伏或220伏。该机利用水下一个550瓦螺旋泵,使水以20升/分的流量通过附加在其上方的弯盘,产生出表面积远远大于水珠的薄薄水膜,增氧效果比普通池塘增氧机提高5倍,而耗能量相同.如果水流位差达0.6米以上,甚至可以不用水泵,从而
At the aquaculture exhibition held in Verona, Italy, in October 1988, a new, exotic and versatile aerator produced in West Germany received much attention. The aerator resembles a giant plastic mushroom with a total weight of 41 kg and a diameter of 1300 mm. It can be used at 380 volts or 220 volts. The machine uses a 550W underwater spiral pump, the water flow of 20 liters / min through the attached to the top of the curved plate, resulting in a surface area is much larger than the water droplets of a thin film of water, aerobic effect than ordinary ponds Oxygen machine increased by 5 times, and the same energy consumption. If the water flow up to 0.6 meters above the level, or even without a pump, which
