HTD系列高压离心鼓风机(简称节能风机)自问世以来,作为冲天炉专用鼓风机,以耗电省、噪音小、效率高、操作维修方便、价格低廉的特点,正引起广大铸造厂家的注意。近年来,用它取代普通低压头离心式鼓风机化铁,一般都能取得良好的溶炼效果。而用它取代使用最广泛的罗茨鼓风机化铁,则使用效果有好有坏,各不相同。对它的评价也褒贬不一。于是,能否在中小冲天炉上用节能风机取代罗茨式鼓风机化铁,便成为广大铸造工作者十分关心的一个问 HTD series of high pressure centrifugal blower (hereinafter referred to as energy-saving fan) since its inception, as a cupola dedicated blower to power-saving province, low noise, high efficiency, easy operation and maintenance, low price, is attracting the attention of the majority of foundry. In recent years, use it to replace the ordinary low-pressure centrifugal blower iron, generally can get a good melting effect. And use it to replace the most widely used Roots blower iron, the use of the results are good and bad, vary. The evaluation of it also mixed. So, can small and medium cupola with energy-saving fan to replace Roots blower iron, it has become the majority of casting workers are very concerned about the question
