摘要

辽宁东方发电公司黄金泵站#1和#2 2台8sh-6J型回水泵

由于长期运行和设备老化

存在入口底阀经常堵塞、轴套磨损严重、盘根漏气等缺陷

造成出力低或不工作的状况

严重威胁机组的正常安全、稳定运行。经分析考证需将8sh-6J型回水泵由填料密封改为机械密封。就改进过程进行了叙述

探求项目改造的技术方案

同时对改进的原因、实施途径和效果加以分析

根据现场实际应用情况

确立了改造后的可靠性。

Abstract

Because of the long-term operation and equipment aging

# 1 and # 2 2 8sh-6J type pump of Liaoning eastern power company gold pump station have some problems

such as bottom valve jams often exist entry

bushing wear

packing defects such as leakage

lead to the low output or not working

a serious threat to the normal safe and stable operation of unit.Analyzing showed that packing seals of 8sh-6J type water pump need to be replaced by mechanical seal.Improved process has been described

and changes to projects of technological solutions are searched.At the same time

improvement reasons

approach and effect are analyzed.Based on practical application

the reliability of transformation is established.
