摘要

输油泵在输运成品油和原油时，其非驱动端轴承箱的垂向往往出现剧烈振动的情况，这些振动会引发泵壳开裂、加速轴承磨损、密封泄露以及泵上部分辅助管路焊缝开裂、出现油品泄露等情况，对设备管理提出很大的挑战。针对输油泵定频工作的特点，本文应用动力吸振技术研制了一款金属波纹管吸振器，输油泵安装该吸振器后的减振效果达到55%，验证了动力吸振技术是一种输油泵振动控制的较好方法。

Abstract

When oil product and crude oil are transported by oil delivery pumps, the violent vertical vibration often occurs at the non-driving end of bearing box, which will lead to some unfavorable effects, such as pump shell cracking, fast abrasion of bearings and seal leakage of the pipe. Besides, auxiliary lines on pump would crack at the welding position and as a result the oil will leak out. All of the possible problems bring great challenges for management of equipments. Considering that the oil pump often works at the fixed frequency, the bellows type dynamic vibration absorber (DVA) is employed to reduce the vibration of oil delivery pumps. The obtained results show that the vibration level of pumps with the bellows type DVA can be suppressed by more than 55%, and it proves that the proposed dynamic vibration absorber can provide one ideal approach for the vibration reduction of oil pumps.
