风机、水泵的耗能在工业部门耗能中占有很大的比例,为此解决风机和水泵的节能问题就成了一项重要任务。目前,国外已广泛应用调节转速的方法来提高风机和水泵的运转效率,从而取得了显著的节电效果。调速液力偶合器就是被广泛应用调速装置之一。船用柴油机研究所研制成功的YDT、YDTW、YDTZ系列调速液力偶合器已被用于全国许多工矿企业,均获得很大的节能效果,一般投入运转后一年左右就可收回投资。
Fan, pump energy consumption in the industrial sector accounts for a large proportion of energy consumption, to solve the energy-saving fans and pumps has become an important task. At present, foreign countries have widely used to adjust the speed method to improve fan and pump operating efficiency, which achieved significant energy-saving effect. Speed control fluid coupling is one of the widely used speed control devices. YDT, YDTW and YDTZ series speed governing fluid couplings successfully developed by Marine Diesel Engine Research Institute have been used in many industrial and mining enterprises all over the country and have achieved great energy-saving effects. Investment can be recovered in about one year after put into operation.
