摘要
四台350S44型循环水泵在工厂做完试验合格后,在现场运行中出现了振动故障。分析中发现引起振动的原因为:(1)伸缩节两端法兰没用长螺杆刚性联接;(2)泵有汽蚀,从而引起振动。并采取了合理有效的措施解决了这一问题。
4 circulation pumps happened with vibration malfunction during run at the site after they are tested to be qualified at manufacturer. There may be two reasons in relation to vibration: ( 1 ) No grid connection with long screw bolt at the flanges of at two ends of extension joint; (2) Vibration' arose out from cavitations. The vibration and cavitations problem have been resolved hy reasonable and effective methods.
