上海人民电机厂于1978年5月研制成功了一种低噪声管道电泵,该管道泵主要用于大型、现代化建筑的空气调节系统中,以及在采暖工程中作为暖水循环泵。电机功率: 1.3千瓦极数:4极水泵参数: NB30--7型,额定扬程7米、额定流量27米~3/时; NB10--15型,额定扬程 15米、额定流量5米~3/时。该厂在试制过程中,针对产品噪声低(指标不大于45分贝),性能好,质量好的要求,在设计,工艺方面采取许多措施,使试制成功的低噪声管道电泵能满足使用要求。该厂降低管道电泵噪声主要采取了以下
Shanghai People’s Motor Factory in May 1978 successfully developed a low-noise pipeline pump, the pipeline pump is mainly used for large-scale, modern building air-conditioning system, as well as in the heating project as a warm water circulating pump. Motor power: 1.3KW Pole number: 4 pole Water pump parameters: NB30--7 type, rated head 7 meters, rated flow 27 meters ~ 3 / hour; NB10--15 type, rated head 15 meters, rated flow 5 meters ~ 3 /Time. In the course of trial production, the factory adopted many measures in terms of design and technology to meet the requirements of low noise electric pump with low noise (less than 45 dB), good performance and good quality. The plant to reduce the pipeline pump noise mainly taken the following
