锅炉给水泵故障机理及诊断技术的研究

本文介绍了锅炉给水泵的故障机理及表现形式，并对锅炉给水泵常见的状态监测和故障诊断方法进行归类和分析。本文还开发了锅炉给水泵的故障诊断软件，介绍了该软件的硬件组成和软件功能．提出了把信号处理方法和分频段控制技术结合起来诊断给水泵故障的方法，并用此方法对M-S型离心泵进行了大量的振动、压力信号测定和分析，初步证明所采用的诊断方法的实用性和准确性。

A Study of Fault Mechanism and Diagnosis Technology on Boiler Feed Pump

This paper introduces the diagnosis mechanism and manifestation of feed pump. Based on the investigation of mechanism, this paper especially classifies and analyses the commonly vibration monitoring and fault diagnosis method on the feed pump. This task includes a fault diagnosis program system which combined the signal processing method and the spectral bands technique. After a mass of determination and analysis on vibration and pressure signal of the M-S Centrifugal Pump, the diagnosis method adopted is proved applicable and reliable.
