孟津电机厂是冷却塔配套动力的生产厂家之一。年产电机3万千瓦,风机3000余套。我们对风机总成电机,应用VE进行了深入地研究和改进,由原来的6.8极电机通过减速装置改为12极电机,取消中间减速装置直接与风机相连。同样降低了转速,满足了冷却塔性能要求,对进一步节能降噪起到了良好效果,给企业和社会增加了显著的经济效益。 一、对象选择 我厂生产的风机系列产品,由Φ0.7～Φ6米,共30余种规格型号。其中Φ1.4～Φ1.8米三种规格型号产量较大,产值较高。对节能降噪,降低成本有显著作用,决定选Φ1.4～Φ1.8米风机总成作为VE分析的对象。
Mengjin Motor Factory is one of the manufacturers of cooling tower supporting power. With an annual output of 30,000 kilowatts of motors, more than 3,000 sets of fans. We have conducted in-depth research and improvement on the fan assembly motor and applied VE. The original 6.8-pole motor was changed to a 12-pole motor through a deceleration device, and the intermediate deceleration device was directly connected to the fan. It also reduced the rotational speed, satisfies the performance requirements of the cooling tower, and played a good effect on further energy saving and noise reduction, adding significant economic benefits to enterprises and the society. First, the choice of objects I plant production of fan products, from Φ0.7 ~ Φ6 meters, a total of more than 30 kinds of specifications and models. Among them, Φ1.4～Φ1.8m three types of models have larger output and higher output value. For energy-saving noise reduction and significant cost reduction, it was decided to select φ1.4-Φ1.8m fan assembly as the object of VE analysis.
