DA-350系列离心压缩机是苏联四十年代产品,六十年代我国沈阳鼓风机厂开始仿制。目前国内尚有近百台该产品在运行,用户普遍反映压缩机排气量不足。主要原因是由于中冷器冷却效果不好,化工部门已用庞大的光管冷却器来代替原翅片管冷却器。因此,为了降低能耗和成本,对目前的DA-350系列离心压缩机的中冷器进行适当的改造以适应日益扩大的生产需要是必要的。
DA-350 Series Centrifugal Compressors are the products of the 1940s in the Soviet Union. In the 1960s, our Shenyang Blower Factory began to imitate. At present, there are still nearly 100 domestic products in operation, users generally reflect the lack of compressor displacement. The main reason is that due to the poor cooling effect of the intercooler, the chemical sector has replaced the original finned tube cooler with a large tube cooler. Therefore, in order to reduce energy consumption and cost, it is necessary to properly modify the intercooler of the present DA-350 series centrifugal compressor to meet the expanding production needs.
