通过对Ｈ２型泵在东雷抽黄泵站２０年运行状况的总结，揭示出水泵轴封漏水严重、轴承断裂、过流部件破坏的主要原因是高泥沙水质所致，在修筑沉砂池改善水泵水源条件后，水泵运行状况已有好转。
Through the summary of the operation status of H2 pump in Donglei Pumping Pump Station for 20 years, it is revealed that the water pump shaft seal has serious water leakage, bearing breakage and the damage of overcurrent components are mainly caused by the high sediment water quality. After improving the pump water conditions, the pump operating conditions have improved.
