随着水产养殖业的发展,近年来各种型号增氧机的销售行情日益见好,一是过去从未使用过增氧机的养鱼地区,也用上了增氧机;二是随着养殖密度的提高,增氧机的需求量也就大了。过去叶轮式增氧机所配的浮筒,一般由增氧机和生产厂利用薄铁皮敲敲打打自己生产的,由于薄铁皮易锈蚀,加上可能漏焊、虚焊等原因,质量难以保证,加之钢材价格上涨,目前大部分均以上海生产的塑料浮筒取而代之。而用户对塑料浮筒所持的观点也已由十年之前的试试看转变到现在主动要求配用塑料浮筒了。
With the development of aquaculture, in recent years, various models of aerator sales are getting better and better, one in the past never used aerator fish area, also used aerator; the second is with Raising the density, aerator demand is also large. In the past, the pontoon provided by the impeller aerator was generally tapped by an aerator and a production plant using a thin sheet metal to beat itself. Due to the easy rusting of the tinplate and the possibility of leak welding and weld-joint, the quality is hard to guarantee. Coupled with the rising price of steel, most of the current production of plastic floats in Shanghai instead. The user’s point of view of the plastic buoy also changed from a decade ago to now take the initiative to request the distribution of plastic buoys.
