化肥厂的高压管道,大多存在噪声和振动问题.噪声大的达95～100分贝.振动剧烈的,十余日甚至一两日管道焊口即开裂.为了降低振动,有的工厂被迫减产,甚至停产.一个工厂一年损失即达数百万元.由于管道破裂而造成的火灾、爆炸事故也曾发生多起. 西安交通大学工程力学系近十年来已为30余家企业解决了管道振动问题,为此,多次受到表彰. 化工部特于今年3月6日成立了“化工部化肥
Most of the high-pressure pipelines of fertilizer plants are subject to noise and vibration problems with large noise levels of 95 to 100 dB. Severe vibrations can crack more than ten days or even a day or two in pipe welds. To reduce vibration, some factories are forced to cut production, Even stop production.A factory lost millions of dollars a year.As a result of the pipeline rupture caused by fire and explosion accidents have occurred more than.Xi’an Jiaotong University Department of Engineering Mechanics over the past decade has been more than 30 companies to solve the pipeline vibration Issue, for which, many times by the commendation.Ministry of chemical especially in March 6 this year, set up a "Ministry of chemical fertilizer
