风机紧固件的失效和控制措施

Invalidation and Control Measures of Fan Fastener

从冷却塔轴流风机对轮毂处紧固螺栓易发生松动和断裂等问题入手,再结合现场实际运行情况深入分析了失效的原因,并采取了相应的控制措施,在一定程度上降低了螺栓失效的故障率,从而确保了风机的可靠运行。

Starting with problems of fastening bolt at the hub of axial fan for cooling tower being easy loose and breaking, the invalidation reason is deeply analyzed combining with the practical running condition in field, and the measure is taken, trouble rate of bolt invalidation is reduced to a certain extent, and thus, the reliable running of fan is ensured.
