摘要
水泵填料轴封经常滴漏的原因是现有水封结构和密封材料不利于密封，改造后，取消水封结构更换了密封材料，密封效果较好，可达到填料压盖处长期不滴漏，泵耗功减少的效果。
The reason of often leakage for water pump packing shaft seal is that the present water seal structure and seal material are not suitable for seal. After reconstruction,the water seal structure is canceled,the seal material is changed.The seal effectiveness is fairly good.So that,the packing at gland does not leak for a long time,and the energy comsumption of pump is decreased.
