摘要
隔膜计量泵当前已成为流体计量应用的主力泵型,但由于其具有周期性的吸入排出浆料的工作特点,导致管道系统内产生了激振力,激振力使管道产生振动,严重时导致管道破裂、介质外泄,引起严重的生产事故。笔者通过实际应用中的案例,从各方面分析了产生激振力的原因,并根据分析、计算结果解决了所遇到的激振力所产生的振动破坏问题,对实际应用有一定的参考意义。
Diaphragm measuring pump has become the main type of pump in the application of liquid measuring. However, the working characteristic of this pump is periodic suction and discharge of slurry, which causes pipe vibration and in severe case pipe breakage and medium leakage as well as serious oper- ation accidents. Based on practical application, lution to the vibration damage brought about by tion. this article analyzes the cause of vibration, provides a so- the exciting force, which can be a reference to applica-
