泵振动的原因及其消除措施

Cause of vibration of pump unit and measures to eliminate the vibration

针对泵机组的各部件存在的振动,分析了产生振动的原因。从泵的水力、机械结构设计,到泵的安装、运行、维护等方面,提出了减轻泵振动的措施。结果表明,保证泵零部件结构尺寸、精度与泵的无过载性能等水力特性相适应;保证泵的实际运行工况点与泵的设计工况点吻合;保证加工精度与设计精度的一致性;保证零部件安装质量与其运行要求的一致性;保证检修质量与零部件磨损规律的一致性,可以减轻泵的振动。

The cause for the vibration of the pump unit was discussed. Some measures to reduce the vibration were proposed concerning design installation, run and maintenance. The results indicated that the vibration of the pump unit could be alleviated through retaining some consistency between the dimension and precision of mechanical part of the pump unit, avoiding overloading, and ensuring the pump unit worked under the design requirements.
