摘要
通过分析前置泵的运行工况,找出QG400/300前置泵存在残余轴向推力的原因。根据该型泵现有结构特点、现行检修工艺中轴承的安装方式、端盖间隙测量和调整方法,运用轴承室结构分析和公差配合原理,指出其存在的问题,从而提出正确的端盖间隙调整方法,获得了较好的使用效果。
The author identify the reason why the QG400/300 booster pump has residual axial thrust by analyzing booster pump＇s operating condition. According to present characteristics of the pump structure, the existing installation way of maintenance process, cover gap measurement and adjustment methods, the author points out existing problems by the use of analyzing bearing structure and the principles with tolerance and fit ; thus puts forward a correct method for cover gap adjustment to obtain a good application effects.
